An exploration into the school related factors that causes high matriculation failure rates in Physical Science in public high schools of Alexandra Township
The exploratory study investigated school related factors responsible for high matriculation failure rates in physical science in public high schools of Alexandra Township in South Africa. The target population included all Further Education and Training (FET) science educators and learners in Alexandra Township. An extreme-case sampling method was used to select a sample of two schools. Data was collected through two different closed questionnaires, one for educators (n=10) and the other for learners (n=250). The results were analyzed using mainly descriptive statistics. The results, according to the views and opinions of educators and learners showed that the main causes of high failure rates are poor educator qualifications, outdated teaching methods, massive workloads, high levels of absenteeism and acute deficiencies in aspects related to: resources, subject content, classroom management skills, proficiency in language of instruction and assessment, motivation and perseverance. Recommendations for practice and policy are suggested.
Computer Assisted Learning For Enhancing Mastery Of Concepts In Science
This study examined the effects of Computer Assisted Learning (CAL) on the mastery of Science concepts by learners in universities. Teaching and learning of Science concepts present learners with numerous challenges. Of critical concern is the negative perception by learners that Science based subjects are difficult, thus contributing to widespread poor performance by the learners in the national examinations and subsequently poor choice of the subject in the universities. Solomon Four Group experimental design was employed for the study. The target population comprised all first-year students taking science subjects in 8 universities in western Kenya. A sample size of 335 students was determined using Krejcie & Morgan table (1970). The universities were divided into two forming experimental and control groups.  The study was carried out in 4 months spanning 16 weeks where pretest was administered after the first 8 weeks of conventional teaching and post-test administered after the next 8 weeks of treatment. Pretest and post-test Science Achievements Test (SAT) on two topics, digestive system and light and optics, were designed and administered by the respective lecturers, and scores recorded. Piloting was carried before the use of the instruments, and a reliability coefficient of 0.85 on SAT was recorded.  Data were analyzed using t-test one-way ANOVA. The study found that 171 students taught using CAL achieved significantly higher scores in SAT compared to164 students taught through conventional methods with a mean gain of 2.851. The study demonstrated that CAL enhanced active manipulation of content and promoted interaction with content, and gave reality to abstraction. The study may be significant to educationists, lecturers, researchers, and policy makers as it provides insight on the benefits of applying Computer Assisted Learning in Science Education.
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.
