This study on the Estonian lower secondary (7-9th grade) science curricula, is seen as an important framework for educators preparing students as tomorrow's citizens able to reflect on sustainable energy development. As the curriculum is taken to be the major document allowing insights into Estonian educational standards, this study identifies components within the intended lower secondary science curricula for subjects of biology, chemistry, earth science, physics, and interdisciplinary science. Using document analysis, verbs associated with career-related learning outcomes are detected, allowing the relatedness of the energy conceptualizations and determination of their cognitive level utilizing SOLO (Structure of Observed Learning Outcomes) taxonomy. A team of coders identify a total of 782 learning outcomes across three learning domains: psychomotor (176), affective (32), cognitive (574) at unistructural (33), multistructural (225), relational (276), and extended abstract (40) levels. The majority of energy concept learning outcomes (274) are identified in the source (form) and transfer (transform) categories. Very few career-related learning outcomes are detected with the science education relevance dimensions (individual, societal, career). The suitability of the findings is discussed. The current analyzing method can be applied to other educational disciplines for raising awareness of disciplinary crosscutting concepts.

The phlogiston theory was established around 1700 and lasted for about one hundred years. According to the Phlogiston Theory, phlogiston is released during heating processes, and the remaining material becomes lighter. The demise of this theory started with Lavoisier’s new insights into the phenomena of chemical reactions in general and combustion in particular, as well as about the composition of air. The rise and fall of the Phlogiston theory is a good example to the process of the replacement of one theory by another, due to new facts and new discoveries. In addition, it stresses the advantages and limitations of scientific models and theories, as well as the nature of science. A brief program, planned for two lessons, was developed around the Phlogiston Theory, in the framework of teaching and learning the “Science: An Ever-Developing Entity” program. Semi-structured interviews with teachers and students were conducted after the completion of the Phlogiston topic. Based on the findings, it is suggested that the brief program, reached its goals. The students, who studied the program, learned more about the scientists – their curiosity and their boldness, as well as about the scientific endeavor, consisting of discoveries, models and theories.

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65-83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country.

The use of the historical approach in teaching science has been studied for many years. Many researchers claimed that this approach has the power to improve students’ understanding of the nature of science (NOS) by emphasizing not only the products of science but also the evolution of its ideas. In this paper we will deal with historical stories which were integrated into the science curriculum of primary, middle, and secondary school students from Arab schools in the Israeli Galilee (270 students). Integrating short historical stories in science teaching is a pedagogical approach in which teachers use the chronological story of scientific discoveries and the evolution of scientific ideas in order to render students’ perceptions of the conceptual aspects of science, its processes and contexts more accurately. The stories in this paper refer to discoveries by four scientists: Galvani (the discovery of the electrical current), Fleming (the discovery of penicillin), Archimedes (the discovery of the floating principle), and Kekulé (the discovery of the structure of the benzene ring). At the completion of enacting this curriculum, the students were asked to write their reflections. By reading the students’ reflections we found out that they noticed that certain circumstances must be present in order to enable a scientist to make his discovery.

The main goals of this study were to find why some students in the 10th grade do not choose to major in any of the science disciplines, and how to arouse their interest in science. The assumption was that the way students perceive and evaluate their acquaintance with any kind of knowledge was very important in their learning process. If students were not interested in science, they would tend not to make an effort to learn and understand the meaning of concepts that were being taught to them. It was shown that the most effective factor contributing to students' decision to study science was their interest in the subject. We developed questionnaires, and disseminated it among 10th grade students, all between 15 and 16 years old, from three high schools located in the central part of Israel, among middle to upper socioeconomic homes. Based on the findings we concluded: (1) Despite the fact that 10th grade students studied science for three years in junior high school, many of them were unfamiliar with basic concepts that appeared in the science syllabus, and (2) the degree of interest shown by students in a given subject was greater when they were familiar with the subject and thus wished to hear and know more about it. Therefore, students' exposure to various scientific subjects can be expected to induce them to show more interest, arouse their curiosity and enhance their desire to know more. Following these results, we attempted to use a historical approach to science teaching, with the belief that it would improve the attitudes and interest of non-science-oriented students (those who did not choose to major in any of the scientific disciplines) towards science and science studies.

Action research is suggested as a way to engage teachers in curriculum development and the betterment of teaching practices in schools based on educational research activities. As in other educational domains, action research in science education is employed with both aims to better understand and develop teaching practices and to contribute to teacher continuous professional development. A variety of methodological approaches using action research in science education exists, from more technical toward more emancipatory interpretations. The range of educational settings and goals for which action research is performed is also quite broad. The purpose of this analytical review of the international available literature is to provide an overview of the main aspects in applying action research in science education.

The study describes the process of adopting new curriculum materials, which had been developed in the PARSEL project in several European countries, into the local educational science classroom of another country. The goal of the PARSEL project was to raise the popularity and relevance of science teaching by enhancing students scientific and technological literacy and by identifying suitable teaching/learning materials, based on relevant context-based educational approaches. All PARSEL materials are organized in a website and are freely accessible by science teachers around the world. In order to increase the teachers ownership towards the new materials, a "bottom-up" approach that included a teacher workshop for modifying the PARSEL modules for the needs of teachers was implemented. The teachers used the modified modules in their classes and reflect upon the whole process, after it was completed. Data have been collected using various research tools, such as, teachers questionnaires, teachers interviews and teachers focus group interviews. The results indicate that the "bottom-up" process increased teacher ownership towards the PARSEL modules and helped the teachers to align their teaching with the philosophy and the teaching style of the PARSEL project. It was also indicated that the students found the modules to be popular and interesting. (Contains 1 figure and 3 footnotes.)

Two different approaches for chemistry education are presented in this paper: teaching and learning chemistry through contemporary research and using a historical approach. Essential dimensions in science education are used to study the differences between the two approaches. This includes the rationale of each approach, the scientific content, as well as students’ and teachers’ perspectives. At first glance, the two approaches look different and even contradict each other. However, a deeper investigation shows that there are common themes that connect the two approaches. Chemistry education is used to represent the historical approach and Nanoscale Science and Teachnology (NST) in chemistry education is used as the context for learning science through a contemporary research approach. The paper can be used by chemistry teachers as a preliminary guide for consideration of adapting one of these approaches in their class.

Educational research and policy suggest inquiry as one of the most prominent ways of promoting effective science education. However, traditional approaches towards inquiry learning are not always sufficiently motivating for all learners. The EU-funded project, TEMI--Teaching Enquiry with Mysteries Incorporated, suggests that mysterious scientific phenomena introduced via drama-based pedagogies and showmanship skills could have the potential to engage more students emotionally in science and to entice them to solve the mysteries through inquiry. This paper reports teachers' views on using storytelling in connection with mysteries in the science classroom. The data stem from a case of chemistry teachers' continuous professional development within the TEMI project in Israel. Data were collected from 14 teachers by means of a questionnaire, interviews, observations, and written reflection essays. The case discusses teachers' views on the benefits and difficulties of using story-based science inquiry activities.

This study focused on teachers' transfer of a variety of teaching methods from a teaching module on nanotechnology, which is an example of a topic outside the science curriculum, to teaching topics that are part of the chemistry curriculum. Nanotechnology is outside the science curriculum, but it was used in this study as a means to carry out a change in the way chemistry teachers teach. The participants in the study included nine high school in-service chemistry teachers. Three research tools were used: (1) semistructured interviews that were conducted with the teachers, after they had finished teaching their nanotechnology module, and follow-up semistructured interviews that were conducted 2 years after the teachers had taught the nanotechnology module , and teachers' assessment and evaluation of their own teaching method, determining how the nanotechnology modules influenced the students who learned according to this program. The data collection process continued for 5 years. Most of the teachers indicated that they continued teaching the nanotechnology module that they designed and all of them stated that they integrated the unique teaching methods into their teaching of chemistry. High efficacy beliefs were built based on the self-evaluation process that was part of the teachers' professional development program. Teaching self-efficacy beliefs and organization efficacy beliefs was found to contribute to teachers' sustainable changes. The findings in the current research are only limited to the topic of nanotechnology; however, we believe that similar results can be obtained for any modern scientific topic that is outside the high school science curriculum. We suggest that more research should be done to determine whether the same findings emerge by using the same approach but on another topic.

This paper presents a study focusing on differences in Israeli Jewish and Arab chemistry teachers' beliefs regarding teaching and learning of chemistry in the upper secondary schools. Israel is a country experiencing the problems of diverse cultural orientation of its inhabitants but applying the same educational system to its diverse cultural sectors. Education includes the same curriculum in chemistry for both the Israeli Jewish and Arab cultural sectors as well as final examinations (matriculation) set centrally by the Ministry of Education. Thus, this study can serve as a striking case for other countries facing similar cultural diversity. The study is based on two different instruments that are both qualitative and quantitative in nature. The qualitative data stem from chemistry teachers' drawings of themselves as teachers in a typical classroom situation accompanied by four open questions. The data analysis follows three qualitative scales: beliefs about classroom organization, beliefs about teaching objectives and epistemological beliefs. A quantitative study gives insights into teachers' beliefs about what characterizes good education. The main goal of the present paper is to determine whether both groups of chemistry teachers with different sociocultural background in Israel hold different views about education in general and chemistry education in particular. The findings provide evidence that in Israeli chemistry classrooms, the beliefs of Arabic teachers differ from those of the Jewish teachers, although both groups live in the same country and operate the same educational system.

The current study deals with freshman students who study at the Department of Science at the Faculty of Education. The aim of the study was to investigate the effect of teaching electrochemistry concepts using Predict-Observe-Explain (POE) strategy. The study was quasi-experimental design using 20 students each in the experimental group (EG) and control group (CG). An Open-Ended Test (OET) and Multiple Choice Test (MCT) were used as pre- and post-test respectively. The POE was used to treat the experimental group, post test scores showed a statistically significant difference in performance by the EG, which had less misconception. The results of this study suggest that using The POE strategy is conceptual understanding.

The present research is part of a longitude research study regarding the questioning behavior of students in the inquiry chemistry laboratory in Israel. We found that students who were involved in learning chemistry by the inquiry method ask more and higher-level questions. However, throughout the years, we have observed that differences between the two groups of students, control and the inquiry, have been reduced. The results of our study indicated that the gap between the Jewish and Arab students regarding their questioning ability is minor and inconsistent. If we assume that the source of this difference lies in the culture and different standards for teachers' qualifications in the two sectors, our current results suggested that the differences between chemistry teachers in the two sectors are now diminished. Teachers from both sectors utilized the inquiry program as part of their teaching repertoire, and the students in the two sectors learned the inquiry skill of asking questions.

This paper discusses essential elements of the philosophical works of Ludwik Fleck (1896-1961) and their potential interpretation for the teaching and learning of science. In the early twentieth century, Fleck made substantial contributions to understanding the sociological character of the nature of science and explaining the embedding of science in society. His works have several parallels to the later and very popular work, "The Structure of Scientific Revolutions," by Thomas S. Kuhn, although Kuhn only indirectly referred to the influence of Fleck on his own theories. Starting from a short review of the life of Ludwik Fleck, his philosophical work and its connections to Kuhn, this paper elaborates upon and illustrates how his theories can be considered for science education in order to provide learners with a better understanding of the nature of scientific endeavor and the bi-directional science-to-society links.

One of the goals of science education is to provide students with the ability to construct arguments--reasoning and thinking critically in a scientific context. Over the years, many studies have been conducted on constructing arguments in science teaching, but only few of them have dealt with studying argumentation in the laboratory. Our research focuses on the process in which students construct arguments in the chemistry laboratory while conducting various types of experiments. It was found that inquiry experiments have the potential to serve as an effective platform for formulating arguments, owing to the features of this learning environment. The discourse during inquiry-type experiments was found to be rich in arguments, whereas that during confirmatory-type experiments was found to be sparse in arguments. The arguments, which were developed during the discourse of an open inquiry experiment, focus on the hypothesis-building stage, analysis of the results, and drawing appropriate conclusions.

An inquiry-oriented laboratory in chemistry was integrated into the chemistry curriculum in Jewish high schools in Israel, and after a short period was also implemented in Arab sector. In this study, we investigated the effect of culture on the perceptions of laboratory classroom learning environments by comparing the perceptions of Arab and Jewish high school students who learned the inquiry-oriented chemistry laboratory. The learning environment is influenced by student-teacher relationship and we thought that this relation is an important issue in the inquiry laboratory and is different between the Arab and Jewish populations. However, until recently, the Arab teachers have remained in the centre of the learning process and their students perceived them as the main source of knowledge and information. In this study, we used both quantitative and qualitative methods to determine whether the laboratory learning environment was different in Arab and Jewish classes that learned in the inquiry-oriented laboratory in chemistry. A statistical comparison of Arab and Jewish inquiry groups revealed significant differences in their actual and preferred perceptions. From the qualitative part of the study, we found that the teachers and students from the Arab and Jewish sectors were statistically similar in the categories that we measured during the inquiry phase, but they were statistically different during the pre-inquiry phase of the laboratory. From the interviews with the teachers and the students, we found that there were differences in the student-teacher relationship between the two sectors.

Action research is defined as using research activities to develop concrete societal practices. Action research understands the change of practice as being already a central aim of the research process itself, and it also seeks to contribute to the professional development of all participants in the particular field of study. Even though (or maybe even because) action research has a long history in the literature, there is a wide variety of interpretations of it. These range all the way from research supportive, via interactive, to emancipatory approaches. There is also a broad range of objectives covering both improving professional environments and generating results of general interest. This paper explores the spectrum of justifications given for action research with a specific focus on science education. Two completely different examples of action research selected from Israel and Germany help illustrate the diversity of the topic. The Israeli case focuses primarily on the professional development of a group of teachers; the German example hones in on the development of suitable curricula and lesson plans for wide dissemination. Comparison of these two projects is embedded in a theoretical framework which categorizes the different action research modes and contemplates teachers' professional development. The aim of this paper is to reflect upon the common potential inherent in differing forms of action research on science education, including the aspect of professional development among teachers.

Laboratory activities have long had a distinctive and central role in the science curriculum, and science educators have suggested that many benefits accrue from engaging students in science laboratory activities. Many research studies have been conducted to investigate the educational effectiveness of laboratory work in science education in facilitating the attainment of the cognitive, affective, and practical goals. In Israel, on 2000, the chemical education committee, based on a needs assessment survey, recommended that the new syllabus include a whole unit of inquiry-based laboratory as part javascript:;of the learning sequence. The reform highlighted the laboratory unit as the central component in the new curriculum. In this paper we will describe the chemistry laboratory curriculum in Israel, its development, implementation and assessment strategies. (Contains 1 table and 2 figures.)

Chemical bonding knowledge is fundamental and essential to the understanding of almost every topic in chemistry, but it is very difficult to learn. While many studies have characterized some of the central elements of knowledge of this topic, these elements of knowledge have not been systematically organized. We describe the development and testing of a matrix that represents: (A) a systematic organization of the conceptual knowledge on chemical bonding required at high school level and (B) a tool for representing students' conceptual knowledge of this topic. The matrix contains three strands: the structure of matter at the nanoscopic level, electrostatic interactions between charged entities, and energy aspects related to bonding. In each strand there are hierarchically ordered cells that contain fine grain elements of knowledge. Using various instruments, students' conceptual knowledge of chemical bonding was assessed and mapped onto the matrix, generating graphical representations of their knowledge. New computational and online technologies enable automatic data collection and its analysis. Therefore, we believe that this organization and representation of small grain size elements of knowledge can be useful for the development of a detailed diagnostic tool of knowledge of chemical bonding.

Discussions held in the chemical education community have generated a variety of reports and recommendations for reforming the chemistry curriculum. The recommendations refer to teaching chemistry in the context of real-world issues. This has been suggested as a way to enhance students' motivation. It is suggested that real-world problems emphasize the interdisciplinary nature of chemistry and the relevance of chemistry to the students' lives. An attempt was made to incorporate these recommendations into the teaching of chemistry by teaching analytical chemistry together with environmental chemistry. A unit incorporating analytical chemistry in an environmental context was developed, in which the students learn concepts of a specific environmental issue. The unit "I Have Chemistry with the Environment", consisting of two modules, was developed on the topics of drinking-water quality, and the greenhouse effect. The research questions focus on the change in the attitudes and perceptions of the students toward chemistry and environmental issues, after learning the environmental unit. The results indicate that the students underwent a significant change in their awareness of environmental issues. All the students mentioned that the unit influenced their everyday-life perceptions of environmental issues and that their awareness of environmental issues increased. Another important finding was that more students found that learning the "I Have Chemistry with the Environment" unit encouraged them to learn chemistry. They indicated that they especially appreciated the feeling that they could discover things by themselves. Clearly, the students found that learning the unit was relevant to chemistry learning as well as to their personal lives. Researchers believe that such a program may promote education for sustainable development. (Contains 4 tables and 3 figures.)

In order to cope with complex issues in the science-technology-environment-society context, one must develop students' high-order learning skills, such as question-asking ability (QAA), critical thinking, evaluative thinking, decision-making, and problem-solving capabilities within science education. In this study, we are concerned with evaluating the effect of student-teacher interaction--which is regulated by culture and traditions--on the QAA in science classroom in general and, specifically in our case, in chemistry laboratory classroom. We take Arab and Jewish sectors that are according to the literature different in their culture and tradition, as a model for our investigation. Specially developed and validated tools, including a novel practical test and an adapted article followed by a questionnaire for evaluating QAA, were administered to the research student population, and the responses were analyzed quantitatively. Observations were conducted in order to better understand the quantitative results that we got. Our findings indicate that there was a difference in the QAA between the 2 sectors. According to our findings, we assume that cultures, tradition, norms, social structure, modes of living, and related factors play a significant role as far as the development of students' QAA and apparently any intended attempt targeting the QAA paradigm shift must take into consideration the multicultural context within which it is to be implemented.

In order to help teachers to bring their students into contact with the frontiers of chemistry, a special program for enhancing chemistry teachers' content knowledge as well as their pedagogical knowledge was launched at the Weizmann Institute of Science. The program, which was specifically designed for the chemistry teachers, consists of three stages, in which the teachers attended (1) the course lectures, together with the regular M.Sc. students, (2) a "Follow-up" tutoring lesson, which was prepared especially for them by one of the staff scientists and was aimed at elaborating on the course lecture, and (3) a workshop coordinated by a researcher from the science teaching group, in order to apply the scientific knowledge to the educational field. The model reduced the teachers' anxieties resulting from taking academic scientific courses; they gained modern and advanced scientific content knowledge, and succeeded in applying it in their teaching. (Contains 4 tables and 4 figures.)

Traditional curriculum for teaching bonding often fosters the use of over-simplifications and over-generalizations. Therefore, there is a need for a presentation that is consistent with current scientific knowledge and that provides the student with the proper intellectual infrastructure for further studies. In this article, we present a general framework for bonding that can be presented at different levels of sophistication depending on the student's level and needs. This is achieved without sacrificing the benefits of traditional qualification of different bond types as this qualification is presented along a continuum scale of chemical bonding. The pedagogical strategy for teaching this model is a "bottom-up" one, starting with basic principles and ending with specific properties. It is our hope that its use could remove learning impediments and enhance students understanding of the nature of chemical bonds. (Contains 4 figures and 1 note.)

In this study our goal was to better understand the development of chemistry teachers who are involved in a continuous professional development (CPD) programme, focusing on using the inquiry approach in the chemistry classroom-laboratory, followed by protocols assembled in a portfolio that can be used to demonstrate evidence-based practice in chemistry teaching in the inquiry laboratory. Fourteen experienced chemistry teachers participated in a workshop, coordinated by three CPD providers from the Department of Science Teaching, at the Weizmann Institute of Science. The meetings, lasting about three hours, were conducted once a month. Of the fourteen teachers, some were videotaped while conducting inquiry-type experiments in their classes, and were interviewed immediately afterwards. Based on the findings, we conclude that the CPD programme contributed to the professional development of the teachers. The teachers became more reflective and more aware of their practice. In addition, we observed a change in their pedagogical knowledge and content knowledge regarding the inquiry teaching. Moreover, their anxiety concerning the implementation of the programme was reduced significantly throughout the year. (Contains 1 figure and 5 tables.)

We describe a workshop in which 10 teachers from 10 schools, located in central Israel, participated in the development of alternative assessment tools in the context of implementing a new science curriculum for senior high-school students, namely "Science for All" (an STS type curriculum). In order to assist a group of teachers (who began teaching the "Science for All" program) in both teaching and assessment strategies, it was decided that the Department of Science Teaching at the Weizmann Institute of Science would sponsor a workshop for them. An evaluation study was conducted during the workshop and at its completion. The main goal of the study was to evaluate the outcomes of the workshop and to determine whether its objectives were attained. The research tools consisted of (a) an attitude questionnaire administered to participating teachers, (b) structured interviews with the teachers, (c) structured interviews with students, and (d) an attitude questionnaire administered to the students. Based on the results of the questionnaires and the interviews, it seems that all the teachers who participated in the workshop gained self-confidence in using the teaching strategies and assessment methods of this new interdisciplinary curriculum. The interviews with students revealed that their active involvement in their own assessment improved their sense of responsibility for their achievements. The variety of assignments enabled them to be at their best with certain assignments and to succeed less with others. In conclusion, we found that running a new interdisciplinary curriculum requires a professional development program that will stimulate teachers' creativity and diversify the instructional strategies that they use in the classroom. Such skills should improve their ability to understand the goals, strategies, and rationale of the curriculum, as well as their students' learning difficulties.

The traditional pedagogical approach for teaching chemical bonding is often overly simplistic and not aligned with the most up-to-date scientific models. As a result, high-school students around the world lack fundamental understanding of chemical bonding. In order to improve students' understanding of this concept, it was essential to propose a systemic treatment, namely, revising the scientific content, the pedagogical approach, and the assessment methods regarding this concept. Therefore, the main goal of this study was to build a conceptual framework that provides an advanced scientific and pedagogical foundation regarding the chemical bonding concept--one that will guide chemistry curriculum developers as well. A conceptual framework for a new teaching approach was constructed with lead-chemistry teachers, science (chemistry) educators, and research chemists. We suggest that chemical bonding should be taught based on elemental principles and by using the idea of a continuum of bond strengths. Our process includes the formulation of "learning goals" aligned with current scientific knowledge. Moreover, we suggest that constructing assessment tasks on carefully specified learning goals, which are described in terms of "learning performances," may enable educators to foster and examine much deeper levels of students' understanding.
