This paper reports on how different types of teachers responded to in-service aimed at developing investigative-based science education (IBSE) in primary schools, and the extent to which they applied their new skills in the classroom. Common items from evaluation questionnaires allowed data to be combined from three major in-service programmes. Using complete data sets from 120 teachers, cluster analysis enabled three teacher types to be identified: a small group of ‘science unsures’, with low attitude scores and little confidence, who showed no response to the innovation; ‘holistic improvers’, who showed the largest improvement in science teaching confidence; and ‘high level, positive progressives’, who were very positive to science teaching throughout and showed gains in confidence in teachingphysics and chemistry, as well as in demonstrating the relevance of science to their pupils. Taking account of these teacher types alongside interviews and observations, nine developmental stages in how teachers apply their new expertise in the classroom and the whole school are suggested. Major factors influencing application in the classroom are the teachers’ initial science knowledge and pedagogical expertise, and motivating feedback to teachers when pupils responded positively to the innovation. Assessing teachers’ initial level of subject knowledge and science pedagogical expertise to inform the approach and amount of in-service provision is important. Subsequent mentoring as well as support from the school principal when teachers first try IBSE with pupils promotes successful implementationin the classroom.

Science teachers in the England have always relied on the support of largely self‐taught technicians when preparing classroom practicals. The technicians have acquired some of their expertise through ad hoc mentoring by senior colleagues, but very few have had any extended training. This research set out to explore the changing attitudes of 40 science technicians in the English East Midlands who attended four‐day training courses during 2005. Their attitudes towards their current jobs and career as well as the effect of more formal training was explored by using pre‐ and post‐course questionnaires along with in‐depth interviews. Teachers who worked closely with them were also interviewed to gauge the impact of the training courses on the work of their departments. The study revealed that the courses increased most participants’ job satisfaction and their confidence in their craft, but that training benefits could be compromised if communication with line managers was poor.

Three Saturday sessions were provided for 22 pre‐service primary teachers in the Midlands of England to help address their problems in understanding science. The course focused on developing understanding of the major concepts relating to the particulate theory of matter, energy, genetics and evolution rather than knowledge recall. A constructivist strategy using peer discussion of science problems with minimal practical work was used. Participants were given word and picture problems to provoke discussion and challenge existing ideas. Students were encouraged to raise and explore their own questions in a supportive environment. Cognitive change was assessed by examining the students' written explanations of the same problem at the beginning and end of each day. New problems requiring the transfer of ideas, discussed during the sessions, were also posed at the end of each day. Students completed a questionnaire and were interviewed about the teaching approach at the end of the course. They repor...

Changes in 70 teachers’ confidence, attitudes and science understanding were tested before and after a major in‐service programme. Attitudes were assessed using a 49‐item Likert‐scale test that probed attitudes to practical science teaching and in‐service training. Multi‐choice and open‐ended questions measured understanding of electricity; melting, dissolving and evaporation; forces; and investigations. Data on pupils’ attitudes and cognition were also collected. After in‐service, teachers’ confidence about science teaching had improved significantly. The majority, but not all, had developed satisfactory levels of understanding and more positive attitudes. Four broad types of response were identified: high attainers who improved attitudes and confidence; teachers with limited science knowledge who found the course difficult but made improvements; unaffected professionals who were already working well and for whom the course had little effect; and disaffected teachers who showed low levels of confidence a...

This article reports on attitude changes of 300 children, aged 10 or 11 years, from four schools, who visited the UK National Space Centre. Attitudes toward science and space were explored by examining responses to five different attitude scales. These were administered before, immediately after, and 2 months and 4–5 months after a visit to the main exhibition area and Challenger Centre. Observations during the visits and interviews of teachers and a sample of children were carried out. Before the visit girls were more anxious than boys. Immediately afterward, children showed more interest in space and a moderate increase in their views about the value of science in society. Nearly 20% of the pupils showed an increased desire to become scientists in the future. These children also showed a positive advantage over the other children with regard to science enthusiasm and space interest. Two months later, they continued to be more positive about being future scientists but only the girls' scores were still significantly raised. Most children found the Challenger experience positive but had more problems with the exhibition area. Teachers' preparation and support during the visit as well as their personal interest had a significant long-term effect on children's attitudes. © 2004 Wiley Periodicals, Inc.

This paper reports the development of attitudes to science and science teaching scales for primary teachers. The investigation is part of a project intended to improve pupil achievement in science in 16 English city schools. The baseline performance of the attitude scales is reported with 76 teachers, half of whom formed a control group. The 49-item attitudes to science teaching scale of Cronbach-alpha reliability 0.96 has sub-scales of practical science teaching and professionalism. The project teachers were less confident of teaching science than teaching the English language. They particularly lacked confidence in teaching physical processes, 'guided discovery' investigations and planning lessons within the National Curriculum as required in English schools. Attitude findings suggest appropriately focused in-service might be successful. Being a promoted teacher with some subject or administrative responsibility tends to lower certain attitudes to effective science teaching. This 'regression upon promot...

A test to assess teachers' science knowledge and understanding was developed to monitor change over two years of a primary science in-service programme in 31 schools. Two cohorts took a six-month core course on 'Developing and Assessing Investigations'. The 70 teachers' science understanding was measured by multi-choice and open-ended questions on electricity; melting, dissolving and evaporation; forces; and investigations. Three sub-scales were developed that provide good discrimination. Despite the moves to improve primary teachers' subject knowledge, many still have the typical misconceptions that have been identified in the past. Teachers also had a poor understanding of variables and their control. The analysis of the results has enabled a pattern of development to be identified. While the in-service programme enabled the majority of teachers to progress through these stages, this progress did not always take the teachers to the scientific stage. It was clear that teachers need a thorough understandi...

This research explored how the Challenger experience influenced over 655 elementary boys' and girls' general attitudes to science and space during the 5 months after their visit by examining their responses to four different attitude scales. These were administered to the 10- to 11-year-olds immediately before and after the Challenger experience as well as 2 and 5 months later. Knowledge tests were also administered before and after the visit. A sample of children completed an existing measure of anxiety. Although there were mainly positive outcomes immediately after the Challenger experience, there were some negative effects. There were also noticeable differences between boys and girls. Some 24% of pupils were inspired to become scientists. There was also less fear of space travel with a greater appreciation of the use of science to protect the planet after the visit. Most girls improved and maintained their attitudes toward science in society. A sizeable number of pupils were relatively unaffected by the experience and there was a significant negative effect on a small group of anxious girls. There are indications that previsit preparation and careful choice of roles during the simulation are important. © 2002 Wiley Periodicals, Inc. J Res Sci Teach 39: 979–1000, 2002

A pupils' attitude test was developed to monitor change over the two years of a primary science in-service programme. It explores pupils' views about school in general so that changes in science attitudes can be contextualized within the whole school experience; feelings towards science experiments; and perceptions of real-world science. The test was piloted with schools outside the in-service programme. Approximately 2000 pupils were tested in January 1999, September 1999 or January 2000. A random sample of children were retested in June 1999 and compared with a ‘control’ school. All the children in the project were tested again in July 2000. The results indicate a generally positive attitude towards coming to school, with particular preferences for work with computers and working together. As the pupils get older, their enthusiasm for science falls as they find it less difficult or demanding. This relationship appears to be broken by teacher in-service to some extent. Girls in particular also showed a g...

This paper reports on the development stages of three attitudes to science and school scales for use with children aged from 5-11 years. The investigation is part of a project intended to improve pupil achievement in science in 16 schools in an English city. The base-line performance of the attitude scales with over 800 pupils is reported. Attitude sub-scales measure 'liking school', 'independent investigator', 'science enthusiasm', the 'social context' of science, and 'science as a difficult subject' with Cronbach Alpha reliabilities for the year groups varying from above 0.8 to below 0.7. For the sample, both boys' and girls' enthusiasm for science declines progressively with age alongside a similar decline in their perception that science is difficult.

Support material to assist primary teacher mentors to help trainee teachers improve their medium-term and individual lesson plans, as well as their science lessons, was developed. This support material comprised checklists that focused on science, rather than generic teaching, illustrated by examples of trainee teachers' work, with a commentary. The trial of the material involved 64 teacher mentors and 26 trainee teachers. Trainees' practice in science was found to have improved in subsequent unmentored lessons, but good practice was not transferred to other subjects. Teachers also reported that their own practice improved and indicated that the material would be valuable in science in-service training with their colleagues.

A year-long evaluative study of the effects of professional development courses for teachers of primary science and design technology collected data from 21 participants about their pre-course qualifications, university-based course behaviour, concept development, and their views from interviews and written evaluations. In-depth visits to 10 of the participants' schools to monitor classroom change were also carried out. Although progress was identified in all teachers, greater progress was made by teachers on the science course. This appeared to be related to several factors. A limited personal framework due to constant changes in the Technology National Curriculum inhibited the learning of the technology teachers. Additionally the technology course was provided by several experts, whereas the science course presented a consistent model of effective teaching. An additional finding was that conceptual change was only noticeable after 10 days indicating the importance of providing long-term INSET a...

Two instruments designed to ascertain children's conceptions of ‘technology’ were given to 315 English children in Years 2–6. A subset of 81 children and their teachers were interviewed. Responses to the same instruments were collected from 745 Western Australian children in the same year groups. Subsequently their teachers and 164 Australian children were interviewed. The Australian and English children had a similar range of concepts to explain technology, but the frequency of concepts varied. The results suggest that the stages of developing an inclusive concept of technology are mainly chronological, but the rates vary with individuals depending on a number of inter-related factors including home and school influence, ability, gender and opportunity to discuss ideas. Examination of these factors suggests there is a need for specific curriculum provision in technology based on adequate in- service training of teachers, which should also clarify the differences between science and technology. Children also need to be enabled to clarify their ideas through focused activities.

This project evaluated the effect of collaboration via email links on the quality of 10–11 year old students’ science investigative skills in six primary rural schools. After a joint planning meeting, sixty children collected, identified and shared information via email about moths in their area, in order to produce a joint booklet. All email traffic was monitored throughout the project. Indepth structured observations and interviews were carried out at the schools. Children completed daily diaries. The children demonstrated a variety of science skills, particularly observation and recording. Their competence and confidence in using computers, handling email and in manipulating a data base developed during the project. The project identified a number of important issues relating to teacher inservice training requirements, the importance of a suitable progression of IT experiences throughout the school, development in cooperative groupwork for children, and software design.

Children's perceptions about technology were measured using a Writing/Drawing Activity and a Picture Quiz, administered to approximately 300 grade three to six children in six primary schools in th...

Between 1992 and 1994, a picture quiz and writing/drawing activity were administered to three samples of 142 primary teachers in English schools, in order to explore their perceptions of technology. Interviews were also carried out with 13 teachers from six of the schools. The perceptions held by primary teachers ranged from technology as the application of science to designing and making artifacts. Many teachers appeared to be confused about the relationship between the National Curriculum view of technology and that held by general society, with the effect that they are thinking increasingly of technology solely in the school context. Consequently there is an over‐emphasis on model‐making in the classroom. Additionally, teachers were confused about the distinction between technology and science in a way that may be detrimental to both subjects.

This paper reports the development and use of three instruments which comprise a comprehensive technique for describing children's perceptions about technology. The instruments are a questionnaire for upper primary school children, a quiz using pictures instead of written items for lower primary school children and, for both age‐groups, a combined writing/drawing activity which complements the questionnaire or quiz. The instruments are designed to cater for children from a range of age levels, provide information helpful to teachers about children's perceptions of technology, and be suitable for use in research. The instruments were trialled in a total of 28 classes in Western Australian schools and construct validity established by examining the pattern of responses between pairs of instruments completed by the same children. The teachers stated that participating in the processes of developing and administering the instruments was useful and gave them valuable information about children's views...

This study examines children's choice of drawing to communicate their understanding of the concept “technology”. The study explored whether the children's drawings accurately reflected the depth and range of their understanding of technology in a way that was interpretable by others. Data were collected from 314 primary school children in England and 745 children in Western Australia. Children were invited to demonstrate their knowledge and understanding about technology by responding to a writing/drawing activity and a representative subsample were then interviewed about their responses. About two-thirds of children's responses to the activity included drawings. Children held a wide range of ideas about technology and only rarely was a drawing difficult to interpret. Although overall the drawings reflected the range of children's ideas, sometimes they did not reveal the depth or breadth of an individual child's understanding. Consistent with the ideas represented in the drawings, the interviews found that younger children held simpler ideas about technology, while older children held more complex, and sometimes quite abstract concepts of technology. A notable difference between the two countries was the emphasis on “design and make” and a smaller proportion of no response in the English sample, reflecting the greater length of time technology education has been implemented in England compared to Western Australia.

This paper compares the perceptions about technology held by elementary school children in England and Australia. Children's perceptions were measured using a writing/drawing activity, designed for children of all ages, a picture quiz, devised for young children, and a questionnaire intended for older children. In each country, samples of about 800 children in Years 3‐6 were chosen from schools representative of those in their region. The results indicate that although many children only associate technology with computers and modern appliances, overall there is an enormous variety of ideas about technology with the more complex and coherent among older children. Children's attitudes are positive, although older children expressed less interest in technology. The high profile of design and make in the England and Wales Technobgy National Curriculum is reflected by children's emphasis on model‐making, an aspect generally ignored by Australian children. The diverse views children hold underscores t...

This pilot study set out to ascertain whether the level of dependence on resource material is related to teaching experience, existing understanding in mechanics, and perceived self confidence in science and technology. Details of teaching experience and qualifications were obtained from 11 experienced teachers and 10 initial teacher trainees, and understanding of mechanics was assessed by a written test. Each teacher worked through one commercially produced inservice pack about levers, pulleys or gears, and then prepared a 30 minute session for 4 ten year old children. Videos of the sessions were analysed with respect to the extent to which the pack was the sole focus; the amount of integration with other teaching aids and approaches; and the extent individual children's needs were satisfied. Although science qualifications influenced teacher confidence, they were not accurate predictors of relevant knowledge and teaching competence. As the majority of teachers followed pack instructions closely, the children's needs were not always well matched.

Teachers’ confidence and attitudes towards science teaching and science understanding were tested before and after a major in-service programme in 31 schools. The 70 teachers’ attitudes were assessed using a 49-item Likert-scale test. Science understanding was measured by multi-choice and open-ended questions. Data on pupils’ attitudes and cognition was also collected. After in-service, overall teachers’ initial confidence about science teaching had improved significantly. The majority of teachers, but not all, had developed satisfactory levels of understanding and more positive attitudes. Teachers responded to the in-service programme in different ways. Four teacher types were identified: high attainers who improved attitudes and confidence; teachers with limited science knowledge who found the course difficult but made improvements; unaffected professionals who were already working well and for whom the course had little effect; and disaffected teachers who showed low levels of confidence and competence throughout. Pupil cognition and attitudinal differences related to these types were found.

In order to take full responsibility in this increasingly technological and scientific world, citizens need to understand the nature of science so that their decisions are informed appropriately. In addition to young children understanding the nature of science, it is also important that every child appreciates that he or she could aspire to a scientific career.
