A comparison of actual and preferred classroom environments as perceived by science teachers and students

This study of perceptions of classroom environment is distinctive in that, first, it made use of two instruments (the Individualized Classroom Environment Questionnaire and Classroom Environment Scale) which have had very little use in prior science education research and, second, it involved assessment not only of student perceptions of actual environment, but also of student perceptions of preferred environments and teacher perceptions of actual environment. Administration of these instruments to a sample of 2175 junior high school students in 116 classes revealed that the environment scales exhibited satisfactory internal consistency reliability and discriminant validity in each of the three forms (student actual, student preferred, and teacher actual), and that there were some fascinating systematic differences between the profiles of environment scale scores obtained for the different forms. In particular, it was generally found that students preferred a more favorable classroom environment then was perceived as being actually present and that teachers perceived the environment of their classes more favorably than did students in the same classrooms.     

Keeping up: A dilemma for science teachers

This paper is based on interviews with seventy-five science teachers in twelve schools across Australia. The interviews were conducted as part of a D.E.E.T. Project of National Significance. The purpose of the project was to develop a strategy for the professional development of science teachers. The main purpose of our interviews was to listen to teachers' views on what such a strategy should try to achieve. We asked them to talk about conditions affecting the quality of their work, their attitudes to teaching, their professional development, their careers, the evaluation of teaching, and Award Restructuring. Through these interviews we came to understand how many science teachers are loosely connected with potentially valuable sources of support for their professional development. In this paper we focus on one group of “loose connections”; those between science teachers and scientists in other fields, research in science education, and their colleagues within science departments in schools. Specializations: Science education, reflective practice, teaching and learning. Specializations: Professional development, educational evaluation.     

Generative teaching and personality characteristics of student teachers

This study determined the relations between generative teaching and student teachers' social maturity, receptivity to criticism and ability to incorporate criticism. Additionally, the “more effective” and ‘less effective” student teachers were compared with respect to these personality characteristics and generative teaching. The subjects were 97 elementary student teachers. At the end of student teaching assignment, the subjects' generative teaching as well as their personality characteristics were evaluated. Results showed that personality characteristics accounted for 56.8% and 56.6% of the variance in the preactive and interactive generative teaching. The “more effective” student teachers were significantly more generative, more mature, and more receptive; they also incorporated criticism more often than the “less effective” ones.

Characteristics of male and female science teachers

The characteristics of 273 male science teachers were compared with 72 female science teachers randomly selected from a fourteen-state region in the USA. A multivariate analysis of variance found differences between the two groups significant at the p ? 0.0005 level. Female teachers were higher on measures of interest in science and receptivity to change. Males scored higher on science knowledge indicators and on their perceptions of the teaching support they received. No differences were noted on measures of professional development or their perceptions of teaching effectiveness, curriculum, workload, or facilities. The implications of the findings are discussed in terms of science career selection by women.     

A comparison of level of understanding of eighth‐grade students and science student teachers related to selected chemistry concepts

The aim of this study is to investigate and compare level of understanding of eighth‐grade students and student teachers in their final year in the science education department related to concepts of solution, gas, and chemical change. A qualitative and quantitative methodology was used for this investigation. Open‐ended questions and group discussion methods were used for data collection. Moreover, to examine how students visualize these concepts, students were asked to make drawings. The questions were administered to 50 students in Grade 8 and 50 student teachers in the science education department. Group discussions were conducted with 6 students and 6 student teachers. There were surprisingly similar alternative conceptions by both the students and the student teachers despite more instruction on these topics in the education of the student teachers. Based on the results, some suggestions are presented. © 2005 Wiley Periodicals, Inc. J Res Sci Teach     

Research interests of secondary science teachers

In the past few years, science educators and the nation at large have become increasingly concerned about the “Crisis in Science Education.” An underlying cause of this crisis is the nonuniform quality of instruction delivered by secondary science teachers. One way to improve the quality of teaching in the schools is the application of science education research findings to teaching. Most teachers are unaware of the research findings and/or do not apply them in their classrooms. This study helps determine the areas of research which are of greatest interest to secondary science teachers. Results will be used by NSTA to determine the contents of future volumes of the monograph What Research Says to the Science Teacher. A random sample of 600 secondary science teachers was obtained from the National Registry of NSTA. Teachers were sent a 23 item questionnaire that asked them to rate their interest in each research topic on a five point scale. The questionnaire contained the 12 items prepared by a NARST-NSTA committee in 1979 and an additional 11 items using the same format. Demographic data collected from the survey included sex, teaching assignment, role in school, type of school, type of community, years of teaching experience, and familiarity with What Research Says. … Data were analyzed using this demographic data as well as according to whether teachers returned the original or a follow-up questionnaire. Teachers who returned the first questionnaire had basically the same preferences as those who returned the follow-up questionnaire. Sixty percent of the teachers completed the questionnaire in usable form. Overall results of the study based on both frequency of response and on mean rating indicate that the following five topics are of greatest interest to secondary science teachers: laboratory experiences, motivational techniques, effect on college courses, problem solving, and meaningful learning. Analysis of data according to the subject taught indicated that chemistry and physics teachers are more interested in problem solving than biology teachers, and that chemistry, physics, and earth science teachers are also interested in the sequence of the content. Males and females had the same top five interests but in a different order. The same is true for teachers of grades 7–9 versus grades 10–12. Rural teachers preferences varied substantially from those in other settings and differences were also found for teachers familiar with What Research Says … compared to the rest of the sample. For every classification of teacher, the area of least interest was sex difference research.     

Assessment of performance in practical science and pupil attributes

Performance assessment in the UK science General Certificate of Secondary Education (GCSE) currently relies on pupil reports of their investigations. These are widely criticized. Written tests of procedural understanding could be used as an alternative, but what exactly do they measure? This paper describes small‐scale research in which there was an analysis of assessments of pupils' GCSE scores of substantive ideas, their coursework performance assessment and a novel written evidence test. Results from these different assessments were compared with each other and with baseline data on CAT scores and pupils' attributes. Significant predictors of performance on each of these assessments were determined. The data reported shows that a choice could be made between practical coursework that links to ‘behaviour’ and written evidence tests which link, albeit less strongly, with ‘quickness’. There would be differential effects on pupils.

Professional development and perceived needs of science teachers

About 100 science teachers in the Sydney Metropolitan West Region were surveyed to determine their professional development needs and the ways in which these needs could be met. The findings provide a ranking of science teacher perceived professional development needs, a list of possible incentives to motivate science teachers to complete inservice programs (in priority order) and an indication of the preferred modes of presentation to meet professional development needs. In general, science teachers stated a preference for professional development related to modern trends in science education directly related to classroom practice. In contrast to recommendations from DEET, science teachers indicated a preference for traditional models of inservice. Data related to preferred mode of inservice indicated significant gender differences. Specializations: science teacher professional development. Specializations: educational psychology and research design. Specialization: constructivist approaches in science education.     

A “Toolkit” for developing critically reflective science teachers

The purpose of this paper is to describe various “tools” we use to facilitate critical reflection as we teach prospective science teachers. The notion of “tools” refers to materials and experiences used to facilitate prospective teachers’ critical reflection on science teaching and learning. Reflective tools are not intrusive devices used by instructors to analyse mechanically what prospective teachers are learning; rather, these tools are intended to provide prospective teachers with the means to generate and critique their own views of science teaching and learning. Each tool is described herein with respect to its potential use and the way in which it is introduced to prospective science teachers. We conclude with discussion of the potential for reflective tools to contribute to research on reform of science teacher education, with particular attention to primary teacher preparation.     

Studying mathematics problem-solving classrooms. A comparison between the discourse of in-service teachers and student teachers

In the article we compare the approaches of 3 in-service teachers and 3 student teachers when they tried to solve a verbal arithmetic problem in the classroom. Each interaction was studied using a System of Analysis that takes into account the cognitive processes involved in the solution of a mathematic problem and describes the interaction at different levels showing what is done and to what degree teachers and/or pupils are responsible for what is done. The results of the study suggest that both groups of teachers are different in how they direct the student’s attention toward the essential aspects implied in the resolution of word problem. On the one hand, the in-service teachers guaranteed students’ understanding of the problem before dealing with the solution, while students teachers only did so when pupils committed errors. On the other hand, the in-service teachers allowed a high level of student participation, while student teachers took a more prominent role so children’s participation was lower.
