The purpose of this study was to observe the science teaching practices of six primary school teachers in Standards 5 through 7, to learn about their perceptions of teaching science and to examine whether or not their teaching practices were in keeping with what they were taught during teacher preparation as well as Malawi's educational expectations for primary school science based upon MIITEP (Malawi Integrated In-service Teacher Education Program) handbooks. Three research questions were posited: (a) What is the teacher preparation program for primary teachers in Malawi? (b) What were the instructional practices of the six beginning primary school science teachers who were prepared in the teacher training college programs? (c) What connections were evident between what beginning primary school science teachers were expected to learn and what they demonstrated in the classroom? All of the six participants (5 males and 1 female) had completed MIITEP in the past three to five years. The data sources for these science teachers included a self-assessment form, pre-observation interviews, post-observation interviews, and lesson observations. Data were also gathered from MIITEP handbooks and three science teacher educators who were interviewed. The data were analyzed using descriptive analysis. The study revealed that there were matches, partial matches, and mismatches between what the six primary school teachers demonstrated in their classroom as compared with the Malawi Ministry of Education science teacher preparation expectations. Of particular interest were that science teachers did not fully engage pupils in most of the process skills for science teaching, nor did they utilize a variety of appropriate teaching and learning strategies and materials for teaching science. In addition, allotted time for teaching science lessons was not fully utilized due to, among other factors, time conflicts with other official and community welfare duties, and mixing English with vernacular during teaching. Implications for practice and for further research have also been suggested. / Ph. D.

This study began with a concern about elementary teachers, as a whole, avoiding the teaching of science in the elementary classroom. The three main factors noted as reasons for this avoidance were: (1) minimum science requirements to reach certification, leading to a lack of preparedness; (2) lack of exposure to science in elementary school; and (3) general dislike for and understanding of science leading to a low self-efficacy in science teaching. The goal of the Environmental Science Lab for Elementary Educators (ESLEE) was to conduct an intervention. The intervention was lab-based and utilized in-context, constructivist approaches to positively influence participants' abilities to retain science content knowledge and to affect their belief in themselves as teachers. This intervention was created to respond to all three of the main avoidance factors noted above. The research utilized a quasi-experimental, pretest-posttest control group design. Two pretests and two posttests (science teaching efficacy and content knowledge) were given to all 1,100 environmental science lab students at the participating institution over two long semesters. Three experimental/control groups were formed from this population. The Experimental Group was comprised of 46 students who participated in the ESLEE Intervention. Control Group 1 was comprised of 232 self-described preservice educators (SDPEEs) in "regular" labs. Control Group 2 was comprised of 62 nonSDPEEs taught by ESLEE instructors in "regular" lab settings. A DM MANOVA was used to analyze the data. The results demonstrated that the ESLEE Intervention was statistically significant at the p> .05 level for science teaching efficacy between the Experimental Group and Control Group 1, and was statistically significant for both content knowledge and efficacy between the Experimental Group and Control Group 2. More notably, the effect size (delta) results ranged from .19 to .71 and .06 to .55 (partial eta squared) and demonstrated the practical significance of implementing the ESLEE Intervention.

The goal of primary science education is to foster children’s interest, develop positive science attitudes and promote science process skills development. Learning by playing and discovering provides several opportunities for children to inquiry and understand science based on the first–hand experience. The current research was conducted in the children’s laboratory in Heureka, the Finnish science centre. Young children (aged 7 years) which came from 4 international schools did a set of chemistry experiments in the laboratory. From the results of the cognitive test, the pre-test, the post-test, supported by observation and interview, we could make the conclusion that children enjoyed studying in the laboratory. Chemistry science was interesting and fascinating for young children; no major gender differences were found between boys and girls learning in the science laboratory. Lab work not only encouraged children to explore and investigate science, but also stimulated children’s cognitive development.

The international and national assessment results indicated that Turkish students&rsquo / conceptual understanding in science and basic inquiry skills are far behind the expected levels. The reason of low achievement could be attributed to many sources such as family background characteristics, students&rsquo / attitudes, and teaching methodologies. The low socioeconomic environment in the school and crowded classrooms are important facts that should be somehow considered by the educational researchers. The way a teacher teaches in a crowded classroom is important to help students&rsquo / understanding of concepts and development of inquiry skills. The present study aimed to propose a methodology that helps teachers to enhance students&rsquo / understanding of concepts and develop inquiry skills in many schools with various socio-economic-status environments and large classrooms. The method proposed could be called as guided (teacher-directed) inquiry to develop concepts, skills, and affective characteristics of the students such as attitudes. This study was conducted with 168 sixth grade public elementary school students in Ankara in 2006-07 academic year. Repeated measures design was used in the study. Intact groups received either traditional or teacher-directed inquiry instructions. The students in both groups were measured with the unit achievement and science process skills tests, and attitudes toward science questionnaire before and after the instructions, and repeatedly after no treatment by a retention or delayed test. It was found that while the guided (teacher-directed) inquiry instruction made a difference on student achievement in the first unit (Reproduction, Development and Growth in Living Things), it could not make a difference on student achievement in the second unit (Force and Motion). The instruction also made a difference on students&rsquo / science process skills test performance and both the composite and individual attitude scores. It is concluded that guided (teacher-directed) inquiry instruction generally helps students&rsquo / understanding of science concepts and results with achievement in science. It helps students&rsquo / development of scientific skills with authentic experiences. Guided (teacher-directed) inquiry instruction also has an effect on students&rsquo / development of positive attitudes toward science and technology course, specifically on self-concept, anxiety, interest, career, enjoyment, and usefulness dimensions.

The science and technology program developed by the Ministry of National Education of Turkey aims at training students as science and technology literates. In order to achieve this, method implemented by teachers should enhance science process skills, increase achievement and actualize differentiation in the conceptual structure of students. The present study aims to investigate the effectiveness of guided inquiry experiments over traditionally designed experiments on the acquisition of science process skills, content knowledge achievement and differentiating conceptual structure of 8th grade students about floating, sinking, buoyancy and pressure subjects. Guided inquiry laboratory manuals were developed for the experimental group. Traditional confirmation type laboratory manuals were developed for the control group. The study was conducted with 55 eighth grade students at a private elementary school in the Bah&ccedil / elievler district, Istanbul. In this quasi-experimental study, two of the three intact groups assigned as experimental group, while the control group. Unit achievement test (UAT), science process skills test (SPST) and two-tiered test for determining differentiation in conceptual structure (DDSCT) were used as data collection instruments. All of these instruments were administered to the students as pre-test and post-test. It was found that guided inquiry experiments were effective than traditional confirmation type experiments in differentiation of students&rsquo / conceptual structure about floating, sinking, buoyancy and pressure. However, there was not a significant difference in the effectiveness of both inquiry and traditional methods on enhancing the students&rsquo / science process skills and their achievement at the unit of force and motion.

Self-motivated activities, or play, that children choose to engage in are manifestations of a variety of science process skills being used to construct knowledge about their environment. While many people agree that science skills should be fostered at an early age, due to the possible positive influence of a wider base of experiential knowledge and the development of a love of science, there is a lack of research available to support the development of early childhood science curriculum (Bredekamp & Copple, 1997, Brenneman, Stevenson-Boyd & Frede, 2009). This study follows the daily activities of four- and five-year-old children attending a science-based preschool in the southwestern United States. The play activities of the children were observed for their use of the science process skills of observing, comparing, classifying, measuring, communicating, inferring, predicting and experimenting. A wide range of play activities centered around the foundational skills of observing, comparing, measuring, communicating and inferring. The teachers and students combine to create a unique environment promoting excitement and exploration. / text

The purpose of this study was to investigate the difficulties encountered by the grade ten township learners with respect to the concept of electricity. More specifically, the study attempted to explore the learners’ scientific knowledge by investigating their conceptions or alternative conceptions about electricity; the influence of learners’ age, career interests and gender issues on their conceptions of electricity and; the effectiveness of concept mapping (a pedagogic tool designed by Novak in the 1970s) in facilitating the learners’ understanding of electricity. The study was premised on socio-cultural constructivism as well as meaningful learning as espoused by Ausubel (1968). A Pre-Test-Post-Test Control Group Design was adopted in the study in which two comparable groups were used. The data was analyzed using both qualitative and quantitative research methods and the instruments that were used included a conception of electricity (COET) (originally adopted and administered in the Western Cape, Northern Cape provinces and in Norway in 1999 for the purpose of Science and Technology Literacy Project (STLP) with the hope that their reliability and validity was guaranteed); selected learner interviews and evaluation forms. The summary of findings has suggested that the Grade ten learners held misconceptions about the concept of electricity even after they were exposed to intervention that included concept mapping. In terms of the gender issues, there was no significant difference in performance between the boys and girls though the females outperformed their male counterparts at both groups. The underachievement of the older learners compared to the younger ones has also surfaced and that is against expectation since a number of studies carried out earlier (see Ogunniyi (1999)) have already corroborated such findings. With respect to career interests, what the learners indicated as their future dreams, i.e. what they intend to do and become, seems to have been influenced their performance at the pre- and post-test stages. / Magister Educationis - MEd
