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 effect of cognitive responses on the attitudes of preservice elementary teachers toward energy conservation

The investigation attempted to determine if subjects' cognitive responses to a persuasive communication are more highly correlated with attitude change than the recall of arguments presented in the communication. Subjects were exposed to a systematically designed persuasive communication and then tested for their retention of arguments presented in the communication and cognitive responses. Attitude change was significantly correlated with cognitive responses elicited immediately following the persuasive communication and cognitive responses recalled three weeks later. There was no significant correlation between recall of communication arguments and attitude change. The results offer a plausible explanation for the contradictory findings reported in the science education literature regarding the dissipation of attitudes changed using persuasive communication.     

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.     

A comparative study of the effect of certain factors on the teaching behavior of preservice elementary teachers of science

Undergraduate teacher education programs have long attempted to improve the prospective teacher's competence in implementing new curriculum programs, materials, teaching strategies, etc. The following study suggests that there are components of a lesson, other than program and materials, which may exert enough influence on the interaction patterns between teachers and pupils to be given closer consideration in the design of a teacher education sequence.     

Relationship between science knowledge levels and beliefs toward science instruction held by preservice elementary teachers

Aspects of science background knowledge and attitudes toward teaching science were examined among preservice elementary teachers. The results indicated a low level of science knowledge, a negative relationship between science knowledge and attitude toward teaching science, and a marked lack of confidence toward teaching science among the prospective teachers. Some interesting paradoxes were also found. Recommendations concerning preservice preparation, inclusion of academic science coursework, and collaborative efforts between college departments are offered.     

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.     

The effects of cooperative learning in a physical science course for elementary/middle level preservice teachers

Although many studies have shown the effectiveness of cooperative learning in a variety of settings in grades K–12, relatively few have focused on higher education. This study compared two physical science laboratory sections in a course for elementary/middle level preservice teachers. One section was taught in the traditional method, and the other was instructed using the Learning Together technique of cooperative learning. Comparisons between the two laboratory sections assessed any differences in student achievement and collaborative skills. In addition, the cooperative learning group completed a questionnaire that assessed their perception of the effectiveness of cooperative learning compared to more traditional methods of instruction, and their attitudes toward the laboratory section. Although no significant differences were observed in achievement, the cooperative learning group exhibited significant gains in collaborative skills. By the end of the course, cooperative learning students indicated a high comfort level for the laboratory.     

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.
