The Relationship of Authoritarianism to the Behavior of Pre-Service Science Teachers

Heard, Virgil G. 05 1900 (has links)
The problem of this study was to investigate the relationship between the degree of authoritarianism expressed by pre-service secondary science teachers and the ways in which they spent their instructional time. This study was conducted on all students enrolled in the secondary science instructional methods course at a large North Texas area university for the fall semester of 1972 and the spring semester of 1973. The total population for the study was 55 students. To aid in resolution of the problem three purposes were formulated. The first purpose was to determine whether authoritarianism expressed by prospective science teachers was related to the ways they spent their instructional time. The second purpose was to determine if the authoritarianism expressed by prospective science teachers was related to their use of an indirect teaching style. The third purpose was to provide feedback to the prospective science teachers on the ways they spent their instructional time. It was concluded that teachers who were very authoritarian asked fewer questions and a different type of question than someone of lesser authoritarianism. The authoritarian asked questions that could be answered with a short answer such as yes or no, while the lesser authoritarian asked questions that allow the student to have more freedom in his response. Further studies of this type should focus on the teaching of questioning techniques to extreme authoritarians to establish whether they might learn to use divergent questions to teach science indirectly.

Exploring natural science teachers' perceptions of their teaching competence, in senior phase township schools in Soweto

Maema, Elijah Krone 28 August 2012 (has links)
M.Ed. / The aim and purpose of the study is to explore the Natural Science (NS) teachers' perceptions of their teaching competence in Senior Phase township schools in Soweto. An in-depth literature review on theoretical perspective in Natural Science teachers' perceptions of their teaching competence in Senior Phase indicated that these partially addressed the key questions of the study, namely: what are the perceptions ofNatural Science teachers' about their teaching competence in Senior Phase township schools? What competences are perceived to enhance and contribute to Natural Science teaching in Senior Phase schools m Soweto? This study identifies a number of motivational competences that have been derived from current theories. The theory developed from the literature on NS teachers' competences review, facilitated the development of an empirical research. Qualitative research was conducted to explore NS teachers' perceptions of their teaching competence in Senior Phase schools in Soweto. This was with a view to facilitating the improvement thereof wherever necessary. Seven NS teachers from three Diepkloof Senior Phase schools were sampled. It also emerged from the findings of the research that there are, teachers who are not qualified to teach NS subject at the Senior Phase level. There also seems to be a lack of competent N.S. teachers in Senior Phase schools in Soweto. The high numbers of learners in NS classes create challenges for NS teachers to provide individual attention to learners. NS laboratories are poorly equipped and that the district officials do not provide sufficient support to NS teachers so that they can be more effective in their teaching. The study gave the researcher the opportunity to explore the teaching competence ofNS teachers in three Senior Phase township schools in Soweto, where the competence gap had already been expressed. There were many challenges identified by the findings. A comprehensive picture of the many inter-dependant aspects affecting the NS teaching competencies was acquired. The research conducted gave the researcher the motivational framework to establish both the current level ofNS teaching competence and the ideal levels of competences to which the three schools and other schools nationwide could aspire.

An Investigation into Teacher Support of Science Explanation in High School Science Inquiry Units

Hoffenberg, Rebecca Sue 18 July 2013 (has links)
The Framework for K-12 Science Education, the foundation for the Next Generation Science Standards, identifies scientific explanation as one of the eight practices "essential for learning science." In order to design professional development to help teachers implement these new standards, we need to assess students' current skill level in explanation construction, characterize current teacher practice surrounding it, and identify best practices for supporting students in explanation construction. This multiple-case study investigated teacher practice in eight high school science inquiry units in the Portland metro area and the scientific explanations the students produced in their work samples. Teacher Instructional Portfolios (TIPs) were analyzed with a TIP rubric based on best practices in teaching science inquiry and a qualitative coding scheme. Written scientific explanations were analyzed with an explanation rubric and qualitative codes. Relationships between instructional practices and explanation quality were examined. The study found that students struggle to produce high quality explanations. They have the most difficulty including adequate reasoning with science content. Also, teachers need to be familiar with the components of explanation and use a variety of pedagogical techniques to support students' explanation construction. Finally, the topic of the science inquiry activity should be strongly connected to the content in the unit, and students need a firm grasp of the scientific theory or model on which their research questions are based to adequately explain their inquiry results.
