The effects of computer use in science and mathematics education upon the computer literacy of preservice elementary teachers

This study investigated the effects of computer use upon the computer literacy of preservice elementary teachers using two methods of instruction: computer assisted instruction in an earth science course and computer programming in a mathematics education course. Computer literacy was measured by the Minnesota Computer Literacy and Awareness Assessment (MCLAA). For each component of computer literacy, differences in group posttest scores were compared using an analysis of covariance with pretest scores used as the covariate. Pre- to posttest increases in scores for each group were also examined. The results indicated that the treatment given to the computer programming group had little or no effect upon the students' computer literacy, while the treatment given to the computer assisted instruction group had a significant effect upon the affective subscale of the MCLAA. A positive effect was also indicated on the cognitive subscale of the MCLAA. Thus, it appears that an effective method for improving preservice elementary teachers' computer literacy is to involve them in computer assisted instruction, possibly through a science course.     

Studies on attitude toward teaching science and anxiety about teaching science in preservice elementary teachers

These studies examined attitude toward teaching science (ATTS) using an adaptation of the Bratt Attitude Test (M-BAT); anxiety about teaching science (ANX-TS), as measured by the State-Trait Anxiety Inventory (STAI A-State); and selected demographic variables in preservice elementary teachers for the 1977–1978 and 1978–1979 academic years and a follow-up of those students who completed their student teaching in May 1979. The M-BAT and STAI were administered in September at the beginning of Science 6 (earth science and biology course), in December on the next to last day of Science 6, in May on the next to the last day of Science 5 (physical science), and in May 1979 after student teaching. In the two academic years, both ATTS and ANX-TS became more positive during the sequence Science 6-5. Both changes in ATTS and ANX-TS continued to change in a positive direction after completion of Science 6-5, after student teaching. There were differences in the times that the greatest changes in ATTS and ANX-TS occurred. In both studies, the greatest change in ATTS took place between September and December, during Science 6. The greatest change in ANX-TS, however, took place during Science 5 between December and May in the 1977–1978 study. In the 1978–1979 study, the greatest changes in ANX-TS occurred in Science 6, between September and December. The delayed reduction of ANX-TS in the 1977–1978 study may be explained by differences in teaching patterns. In 1977–1978, two teachers taught only their academic specialty, biology or earth science, to students who switched teachers midsemester. In 1978–1979, the same two instructors taught both biology and earth science to the same students. Correlation coefficients for successive and corresponding administrations of both the M-BAT and STAI suggest these variables are related. Students with more positive ATTS tended to have reduced ANX-TS. Neither the number of high school or college science and math courses completed nor the level of enjoyment of these courses appears to be related to ATTS or ANX-TS for the initial administration of the M-BAT and STAI. Closer examination of data, however, indicates that students with negative ATTS and high ANX-TS were fairly evenly divided in their enjoyment of mathematics, while students with positive ATTS and low ANX-TS enjoyed math in a 3:1 like/dislike ratio. The relationship between both ATTS and ANX-TS and achievement is reasonalbly consistent for Science 6. In Science 5, however, the relationship between ATTS and achievement is inconsistent and there is no indication of a relationship between achievement and ANX-TS.     

The effect of problem-based learning on the environmental attitudes of preservice science teachers

This study attempted to investigate the effect of problem-based learning (PBL) on the environmental attitudes of preservice science teachers. In the study, an experimental design was used with a pre-test and post-test control group. In all, 51 junior preservice science teachers participated in the study. The study was carried out over 10 weeks within the scope of an environmental science course. During the study, lessons in the experimental group were processed using a PBL approach while lessons in the control group were processed using a traditional teaching approach. Data were collected through a personal information form and environmental attitudes inventory. Data were then analysed using PASW Statistics 18 (SPSS Inc.). The findings of the study revealed a statistically significant increase in favour of the experimental group preservice science teachers’ environmental attitudes. An increase in environmental attitudes was also found in the control group; however, this increase was not statistically significant. As a result, PBL was found to be more effective than the traditional teaching approach in the development of environmental attitudes in preservice science teachers.     

The development of mathematical competence in Flemish preservice elementary school teachers

A large-scale longitudinal study was conducted in which the elementary mathematical knowledge and skills of a large group of Flemish preservice elementary school teachers from 15 different institutes was assessed by means of a paper-and-pencil test that was administered both at the beginning and at the end of their 3-year training. The 30-items test covered the new standards for mathematics in the elementary school curriculum in Flanders. The test was divided in six subsets differing in terms of the curricular subdomain and of the cognitive operations being addressed by the item. The results confirmed the frequently heard concern that at the beginning of their training preservice elementary school teachers have rather weak mathematical competencies. At the end of their 3-year training, the overall test performance had become substantially better, although there were still reasons to be seriously concerned about the readiness of some student teachers to teach mathematics to elementary school children. A number of more specific comparisons helped to identify the relative role of two different factors—selection and instruction—in student teachers’ gain from pretest to posttest. Besides documenting the development of elementary mathematical competence in preservice elementary school teachers, the study also resulted in an instrument for (self-) assessment of elementary school mathematical competence. This instrument is now being used in many institutes for elementary school teacher training in Flanders.     

The effect of videotape and written channels of communication on the science attitudes of preservice elementary teachers

The purpose of this study was to assess the effect of two channels of communication on attitude change in preservice elementary teachers toward the teaching of science. A science attitude scale was administered as a pretest, posttest, and retention test to 66 preservice elementary school teachers. One analysis of variance for repeated measures was conducted. It was found that videotape and written channels of communication were equally effective in science attitude change.     

Checklist for assessment of science teachers and its use in a science preservice teacher education project

The purposes of this study were to develop instruments to assess the nature of student-teacher relations and classroom activities, and the personal adjustment of preservice science teachers in two concurrent programs and to see if the two groups differed significantly in the three areas measured by the Checklist for Assessment of Science Teachers (CAST). The CAST was completed by university supervisors, cooperating teachers, and classroom pupils in terms of 92 secondary student teachers at the completion of three student teaching quarters. Multivariate analysis of variance was used to detect differences between treatment groups. The major differences between the two groups of science student teachers were the types of classroom activities used and the nature of their student-teacher (teacher-pupil) relations.     

Integrating alternative assessment in a project-based learning course for pre-service science and technology teachers

This paper deals with a required methods course, based on the national curriculum of science and technology for junior high schools. The course participants are pre-service teachers who study towards a B.Sc. degree in education in science and technology parallel to their studies in one of the faculties of sciences or engineering. Working in small teams, the students carry out a project in a Project-Based Learning (PBL) environment. The final outcomes of the project are group and individual written reports, a portfolio, a multimedia presentation and a physical model. The research question was: what implementation issues and processes do higher education students encounter in a Project-Based Learning environment which involves an alternative assessment approach? Qualitative and quantitative tools for collecting data included ‘the participant as observer’ observations at the classroom, semi-structured interviews with students, questionnaire, and analysis of students' reports and products. The findings relate to the advantages of PBL from the students' point of view, the challenges students experienced and perceived while conducting their projects, and the benefits students may gain from formative assessment.     

Efficacy of a gender and ethnic equity in science education curriculum for preservice teachers

The purpose of the Gender and Ethnic Equity in Science Education (GEESE) program, conducted during the student-teaching semester, was to provide preservice science teachers with the opportunity to use clinical observations and reflection as vehicles for discovery of the disparate school experiences of the diverse students in their science classrooms. The preservice teachers examined curricular materials in use during their practicum, student and teacher behaviors, the quantity and quality of student–teacher interactions, and grouping and evaluative strategies before attempting self-analysis at the conclusion of the program. Interviews were used as the source of qualitative evidence of change in the preservice teachers' attitudes and teaching behaviors. While students approved of the program initially, they eventually dismissed issues of gender and ethnic equity as critical once they began struggling with the inadequate academic preparation of their students and scant material resources. Ultimately, the preservice teachers identified the GEESE program as useful in that it provided them with specific critical techniques, but inappropriately placed at the conclusion of their professional development sequence. © 1997 John Wiley & Sons, Inc.
