As in all fields, values are an important component of classroom's affective environment in mathematics course, too, and have a significant impact on students' mathematical efforts. As it would directly affect classroom practices and learning, it is deemed important to determine preservice teachers' value profiles. This research aimed to address mathematical and mathematics educational values of mathematics students receiving pedagogical formation in terms of constructivist and positivist approaches and examine these values along with their opinions on the use of different teaching strategies, methods and techniques (SMTs) in courses. The participants were 288 mathematics students receiving pedagogical formation at two public universities. As data collection instruments, Mathematical and Mathematics Educational Values Scale and a written interview form were used to associate their values with their teaching preferences. The study concluded a significant difference in favor of constructivist values when comparing participants' levels of having positivist values with their levels of constructivist values. The findings achieved from the interview forms indicated that majority of participants preferred student-centered teaching strategies, methods and techniques; in other words, they regarded themselves rather as constructivists.

Storytelling is a popular instrument used in every domain of natural and social interaction for human communication and commonly used in classrooms to enrich the learning experience. With the use of technological tools in every field of our daily lives, its use in educational environments has become inevitable and in parallel with the development of these tools, digital stories have started to replace traditional storytelling. Digital storytelling offers advantages such as providing diverse applications in the classroom environment, personalizing the learning experience, being interesting, helping difficult subjects explained, addressing real-life-related situations, supporting active learning, allowing for the creation of costless learning environments, and improving motivation and achievement. Materializing a course such as mathematics in which abstract concepts are given, helping students use the learned information with stories and associate it with daily life, developing activities to make learning environments enjoyable when learning and applying by taking students away from the traditional understanding of instruction are considered some of the most important duties of teachers in this process. In accordance with the related considerations, this study aims to investigate the effects of mathematics courses instructed by association with digital storytelling on 8th-grade students' academic achievements and the teacher and student opinions on the application process. The study using the quasi-experimental method was conducted with 58 students. The Achievement Test, written opinion forms to receive student opinions and interview form for teacher were prepared by the researchers to this end. At the end of the study, although no statistically significant differences were found between the groups in the posttest and the delayed-posttest in terms of academic achievement score averages of the students in the experimental group were found to be higher than the score averages of the students in the control group. The results achieved in this study show that digital storytelling is a powerful instrument to create more interesting and enjoyable learning environments which facilitate association with daily life, allow for effective learning and participation. It was also stated that the students and the mathematics teacher had positive opinions on use of digital stories in the courses and its contribution to the courses.

Differentiated instruction is an instructional method complying with the constructivist approach that takes individual differences into consideration. Importance of pre-service education becomes apparent so that the differentiated instruction of which positive contributions such as having positive effects on students' academic achievements and enabling them to develop a positive attitude toward mathematics have been shown in mathematics education research can be applied in an efficient way. In this context, the purpose of this study is to examine elementary mathematics teacher candidates' competence of differentiated instruction and their opinions on the process during a pre-service education which has the components through which they become informed of the differentiated instruction method, develop differentiated instructional activities, these activities are observed by teachers and they discuss the effectiveness of the practices. The study group of the research was composed of 49 pre-service elementary mathematics teachers. Accordingly, competence level of differentiated instruction was found to be a value very close to the high level. It is thought that this study will provide information on the points to be taken into consideration in future studies to be conducted on obstacles and conveniences presented by pre-service teachers regarding the use of differentiated instruction method and the learning environment in the light of the practices.

WebQuests are designed to ensure meaningful learning by combining technology with a constructivist approach in the classroom setting. This study aims to examine the effect of WebQuests used in instruction on students' academic achievements and the student and teacher opinions on WebQuests. The participants of this study using the quasi-experimental method were composed of 78 ninth-grade students and five mathematics teachers. Within this scope, WebQuests for the attainments in the domains of Data, Counting and Probability learning in the ninth-grade curriculum were developed by the researchers. The academic achievement test developed by the researchers was applied to the experimental and control groups as pretest, posttest and delayed posttest. In the implementation process, the experimental group was expected to solve the non-routine problems within WebQuests. The student and teacher opinions on the implementation were received at the end. The SPSS software package was utilized for quantitative data analysis and the qualitative data were subjected to a content analysis in the study. Consequently, it was discovered that the WebQuest teaching strategy had a positive impact on the student learning retention. Furthermore, the themes obtained through teacher and student opinions and recommendations of the study emphasize important issues for future studies.

A natural outcome of change in technology, new approaches towards teaching and learning have emerged and the applicability of the flipped classroom method, a new educational strategy, in the field of education has started to be discussed. It was aimed with the study to examine the effect of using flipped classroom method in academic achievements and motivations of students and reveal the student opinions. The quasi-experimental method was used in this study and the participants were 50 sophomores studying Elementary Mathematics Education in a state university. The results of the study shows that the flipped classroom method does not have a significant effect on improving students' perceptions of technology use, and the students in the experimental group were more successful and had higher levels of motivation than the students in the control group. It was also revealed that the students had positive thoughts about the implementation of the flipped classroom method.

As it has changed all fields in our lives, technological advancements have also improved education in such a large extent that integrating technology into education is inevitable. For this reason, teachers and teacher candidates are supposed to get acquainted with technology related information and skills. This study was conducted to determine the pre-service mathematics teachers' opinions about information and communication technologies. A questionnaire was applied to 104 mathematics teacher candidates from a university in the Black Sea Region as the data collecting tool. The data was analyzed with statistical software (SPSS 13.0) in terms of average mean, standard deviation and t-tests. Current findings show that mathematics teacher candidates have positive attitude towards applying ICT in classroom settings. Results show no significant difference between the attitudes and owning a computer, using the internet and the department being studied; however there is a significant correlation between attitudes and gender; favoring males.
