We describe research carried out with a prospective secondary biology teacher, whom we shall call Miguel. The teacher’s conceptions
of the nature of science and of learning and teaching science were analyzed and compared with his classroom practice when
teaching science lessons. The data gathering procedures were interviews analyzed by means of cognitive maps and classroom
observations. The results reflected Miguel’s relativist conceptions of the nature of science that were consistent with his
constructivist orientation in learning and teaching. In the classroom, however, he followed a strategy of transmission of
external knowledge based exclusively on teacher explanations, the students being regarded as mere passive receptors of that
knowledge. Miguel’s classroom behavior was completely contrary to his conceptions, which were to reinforce the students’ alternative
ideas through debate, and not by means of teacher explanation. 相似文献

We explore the initial characterization of the pedagogical content knowledge of four, in-service, Colombian pre-university secondary education physics teachers on the concept of electric field. Two of them teach the content in English as a second language. The aim of the study was to obtain an image of the participants’ teaching of electric field and the inherent complexities that go with that. The results revealed that factors which involved their personal educational models, such as, how they interpret their school’s curriculum, the relationship they see between physics and mathematics, the most effective strategies for teaching physics, and the time they have available to develop the topic played a significant role. The teachers considered it essential to establish new strategies that would motivate the pupils by helping them visualize the electric field. 相似文献

The interest on engineering and scientific studies can be raised up even from the early years of academic instructional process. This vocation may be linked to emotions and aptitudes towards technological education. Particularly, students get in touch with these technological issues (namely STEM) during the Compulsory Secondary Education in Spain (12–16 years old).This work presents a preliminary evaluation of how relevant is Gardner's multiple intelligence theory (MIT) in the teaching–learning process within the Technology Lessons. In this sense, MIT was considered as an explanation variable of the emotional response within the different educational parts (so-called syllabus units, SU) in the Technology spanish curriculum. Different intelligence style (IS) will orient the student to a vision of the engineering and technology. This work tries to identify which relationships can be established between IS and specific technology and engineering learning. This research involved up to 135 students were subsequently tested about their predominant (IS) and on the emotions that arouse in them when working with each SU. The results were statistically significant and only those with a Logic-arithmetic or Environmental IS were not affected by the SU.Best teaching and learning practicesare required for encouraging further engineering studies. 相似文献

Using the responses to open questions, this qualitative study examines the personal metaphors expressed by prospective secondary education teachers, 46 science graduates and 41 economics graduates. The metaphors are classified into the four categories of Leavy, McSorley, and Boté: the behaviourist/transmissive, the cognitivist/constructivist, the situative, and the self-referential. The results showed most metaphors to fall into the behaviourist/transmissive category, followed by the cognitivist/constructivist, self-referential, and situative categories, although some teachers expressed metaphors framed in more than one category. Of the 129 metaphors detected in the study, only one, of a chemistry graduate concerning the equilibrium between reactants, was associated with the prospective teachers' specific undergraduate education. The rest were expressions of their overall vision of teaching and learning, regardless of the speciality. 相似文献

This study analyses the evolution of the personal metaphors of 31 science graduates enrolled in a Master’s degree course in Secondary Education Teaching during the 2012–13 academic year. The instrument used was an open questionnaire that included asking the participants to make drawings representing the roles of the teacher. Four categories of metaphor were considered: behaviourist/transmissive, cognitivist/constructivist, situative/socio-historical, and self-referential. It was found that most of the prospective teachers were indeed able to conceptualize their roles in the form of metaphors. Comparison of the results before and after the teaching practicum revealed no changes in most of the participants’ metaphors and associated models. Instead, these appeared to be firmly set already at the beginning of the Master’s course, and remained uninfluenced by either the course or the practicum. Only a minority of the participants showed changes in their metaphors—5 with progressive changes, and 5 with regressive changes. 相似文献

The self-efficacy of prospective primary teachers was studied, considering in particular the relationship of that construct with the emotions they expect to experience as future science teachers, differentiating between when they will be teaching the content of the ‘nature sciences’ (biology and geology) and that of the ‘hard sciences’ (physics and chemistry). The study instrument was a questionnaire completed by 188 prospective primary school teachers in their initial education at the University of Extremadura during the academic year 2009/2010. The results showed them to mostly have positive emotions towards nature sciences and negative towards the hard sciences. While their beliefs concerning their self-efficacy are significantly related to their emotions about their future teaching of the hard sciences, high self-efficacy was significantly correlated with more positive emotions and fewer negative emotions towards physics and chemistry. 相似文献

One of the most important topics on the international agenda in educational research is to gain an understanding of the processes
of educational change in teachers and of the factors that favour or hinder it. Such understanding is, for instance, an essential
element in planning and putting into practice initial and ongoing teacher education programs. This article reviews the research
on science teachers’ educational change. To organize the information, an analogy is made with the process of scientific change,
analyzing and evaluating the contributions of the different models taken from the philosophy of science – positivism, Popper’s
principle of falsifiability, Lakatos’ scientific research programs, Laudan’s research traditions, Toulmin’s evolutionism,
and Kuhn’s relativism. We conclude the article with the implications for science teacher education. 相似文献

A study was made of different emotions that prospective primary school teachers report with respect to science subjects, when they were pupils, and during their practice teaching, taking into account the variables gender and the speciality they studied in the secondary education. The study consisted of a questionnaire completed by 63 primary education students at the University of Extremadura, Spain. The results show a great difference between the emotions related to the subjects of physics/chemistry and the nature sciences （biology/geology）. The scientific subject influences the emotions of pre-service primary teachers, both in learning and teaching. In physics and chemistry, the emotions are mostly negative. While in nature sciences they are very positive. In nature sciences, there is a correlation between the emotions felt as secondary school pupils learning science and those they feel as teachers. In physics and chemistry, there is a correlation in the women between the emotions felt as secondary school pupils learning science and those they feel as teachers, but not in the men. The memory of their emotions in learning science at school is more negative than in teaching science during their teaching practice, except in nervousness in physics/chemistry. By gender, men declared a greater predilection for science content than women, with more of them describing such feelings as sympathy or confidence. The results highlight the influential role that emotions play throughout the professional growth of future primary teachers. 相似文献

The results are described of two case studies on the conceptions and classroom practice of two Portuguese physics and chemistry teachers on the role of problem solving in the teaching/learning of science. One of these teachers was a novice and the other had about 20 years of teaching experience. The data were obtained from a questionnaire, a semi-structured interview, classroom observation, personal documents, and stimulated recall. The analysis was carried out with instruments organised into categories and specific indicators. The results showed there to be major differences between the intention behind the new curricula, the teachers' conceptions, and their practice. Some suggestions are put forward on the basis of these results for the initial and ongoing education of secondary education teachers of physics and chemistry in Portugal. 相似文献
