AbstractThe problem involved in this experimental study was to ascertain the effect of speed-up teaching methods and procedures on the outcomes of industrial education classes. Speed-up methods and procedures utilized with the experimental group were implemented in eight defined ways. Data for the study were obtained through the experimental method under actual teaching conditions.Teaching methods and procedures designed to emphasize speed of performance were both beneficial and detrimental. Such methods and procedures resulted in a greater quantity of work but also resulted in more errors, greater dependence on the teacher to save time, and the waste of more materials. However, the quality of work was not affected, but the instructor’s task was more difficult. 相似文献

Summaries English The method used to record intellectual transactions in the Science Teaching Observation Schedule (STOS) is examined in the light of the theory of sampling methods and it is concluded that STOS cannot give reliable quantitative data. The usefulness of continued analysis of STOS data is questioned and it is suggested that STOS results should be regarded as indicators for further quantitative examination before scientifically meaningful conclusions can be drawn regarding science teaching styles. 相似文献

Summaries English In this paper, the authors summarize the main findings which resulted from a recent major research study of the processes and products of science teaching in English schools. For the purpose of this study, a Science Teaching Observation Schedule (STOS) was developed by means of which the intellectual transactions taking place between teacher and pupils during science lessons, can be recorded and analysed. Using STOS, the teaching behaviour of some 94 teachers of biology, of chemistry and of physics was studied. On the basis of this, three main styles of science teaching were identified. These styles are described and discussed both in terms of their educational effectiveness (as measured by pupil achievement) and in relation to the implementation of modern school science curricula. 相似文献

Abstract Although teaching is a primary function of social work educators, most instructors receive little training in teaching methods and, once engaged in teaching, have few opportunities to hone their craft and engage in dialogue about their classroom experiences. Teaching Circles are an example of ongoing curricula designed to improve classroom performance, foster support for excellent teaching and, ultimately, improve student satisfaction. This paper describes the rationale, structure, content, incentives, evaluation, and merit of Teaching Circles. 相似文献

Summaries English Scales derived from student responses were used to describe the science learning environments of 14‐year‐old students in 14 different countries. It was found that the best science achievement occured in countries which combined exploratory and authoritarian teaching styles. Within countries, exploratory teaching styles were again associated with high science‐achievement, although the relationship was less strong. These results suggest that some science teachers might improve their pupils’ performance if they adopted more exploratory teaching styles. But no firm conclusions can be reached until the results have been replicated in an experimental study. 相似文献

ABSTRACTThis paper examines the insistent claims by advocates of evidence-based teaching that it is a rigorous scientific approach. The paper questions the view that randomised controlled trials and meta-analyses are the only truly scientific methods in educational research. It suggests these claims are often based on a rhetorical appeal which relies on too simple a notion of “science”. Exploring the tacit assumptions behind “evidence-based teaching”, the paper identifies an empiricist and reductionist philosophy of science, and a failure to recognise the complexity of education and pedagogy. Following a discussion of large-scale syntheses of evidence (Hattie’s Visible Learning; the Education Endowment Foundation’s Teaching and Learning Toolkit), it examines in detail one strand of the latter concerning sports participation, which is used to illustrate flaws in procedures and the failure to take seriously the need for causal explanations. 相似文献

ABSTRACTThis paper assesses the relationship between participation in two tertiary science courses and the science teaching efficacy beliefs (STEBs) of one cohort of preservice elementary teachers over a four-year period. Two Type II case studies were conducted within the courses. Data were collected through 26 administrations of the Science Teaching Efficacy Belief Instrument-B and semi structured interviews. Results showed that participation in the subjects covaried with increases in the participants’ STEBs. These increases in STEBs remained durable for two years. Implications for these findings are discussed within the paper. 相似文献

The intent of the present study is to describe preservice elementary teachers’ understanding of science and how certain contextual variables contribute to this understanding. Eighty students in three sections of an elementary science methods course participated in the study by completing a questionnaire. Six questions dealt with knowledge of science, theories and evolution. In addition, a 21‐item rating scale covering various aspects of science and science teaching was included. The major theme arising out of the data is how beliefs affect preservice teachers’ understandings of science. The anthropocentricity in the subjects’ definitions and purposes of science, theories and evolution is the most explicit and pervasive of the beliefs influencing the conceptualizations of science. The often vague and misinformed definitions of theories add a further dimension of how science is perceived. When evolution is introduced, both the anthropocentric view of science and the misunderstood notion of theory come together to confound the subjects’ understanding. When asked about the teaching of evolution, the subjects’ confusion concerning the nature of science becomes strikingly evident. 相似文献

Summaries English The report describes a study of the teaching behaviour of student‐teachers of science disciplines during the one‐term teaching practice of the English ‘Post‐Graduate Certificate in Education’ course, using the Science Teaching Observation Schedule by Eggleston et al. The results suggest that in several behavioural dimensions, students and teachers achieve a close match. These dimensions, it is suggested, could represent the ‘stable’ elements in the students’ perception of science teacher behaviour learnt during their time as pupils, or they might represent ‘safe’ transactions which do not involve students extensively in problems of classroom management and control. For other behaviour categories, it was found that students tended to behave less like experienced teachers as the training practice proceeded, but this was to some extent determined by the subject taught. Physics student‐teachers substantially maintained their similarity to experienced teachers, whilst chemistry and biology students drifted away. The nature of these drifts is discussed. 相似文献

Background and purpose: The purpose of this study was to investigate the comparative effects of a prediction/discussion-based learning cycle (HPD-LC), conceptual change text (CCT) and traditional instruction on 10th grade students’ understanding of genetics concepts. Sample: Participants were 112 10th basic grade male students in three classes of the same school located in an urban area. The three classes taught by the same biology teacher were randomly assigned as a prediction/discussion-based learning cycle class (n?=?39), conceptual change text class (n?=?37) and traditional class (n?=?36). Design and method: A quasi-experimental research design of pre-test–post-test non-equivalent control group was adopted. Participants completed the Genetics Concept Test as pre-test–post-test, to examine the effects of instructional strategies on their genetics understanding. Pre-test scores and Test of Logical Thinking scores were used as covariates. Results: The analysis of covariance showed a statistically significant difference between the experimental and control groups in the favor of experimental groups after treatment. However, no statistically significant difference between the experimental groups (HPD-LC versus CCT instruction) was found. Conclusions: Overall, the findings of this study support the use of the prediction/discussion-based learning cycle and conceptual change text in both research and teaching. The findings may be useful for improving classroom practices in teaching science concepts and for the development of suitable materials promoting students’ understanding of science. 相似文献

Background: For the past decade, science educators have been exploring the use of Socio-scientific Issues (SSI) as contexts for science teaching and learning, and research indicates that doing so can support significant learning gains. However, research related to how teachers take up the practice of SSI-based instruction is far more limited, due in part to a lack of tools for use in this kind of research.
Purpose: The focus of this research is development and testing of a new classroom observation protocol specifically designed for SSI-based instructional contexts.
Design and methods: Development of this SSI-Observation Protocol (SSI-OP) took place in four distinct phases: review of existing protocols and SSI-based instruction frameworks, writing and revision of protocol items, initial testing of the draft protocol, and soliciting feedback from SSI experts.
Sample: Following the four stages of SSI-OP development, we progressed to a series of field tests. The field tests were conducted with three different samples. The first sample was an experienced (10 + years) high school biology teacher and one of her honors biology classes. The second sample consisted of seven Turkish Pre-service Science Teachers (PST) participating in a science methods course. The third sample included two Thai PST from a field experience course embedded within a teacher education program.
Results: The final version of the protocol addressed five dimensions of SSI-based instructional activities: focus of instruction, teaching moves, role of teacher, role of students, and classroom environment.
Conclusions: The SSI-OP could be used in a variety of ways for research including documentation of current practices, impacts of professional development and/or curricula on teaching practices, and changes in teaching over time. We offer the SSI-OP as a new tool with the potential to contribute to science teacher education and research that may advance the teaching and learning of science through SSI. 相似文献

This paper is, in part, a narrative account of a teacher educator's professional growth during a longitudinal case study of three primary science teachers, Katie, Jean and Ruth, as they made the transition from pre-service to inservice teaching. The study sought to explore ways in which the beginning teachers perceived and dealt with constraints to science teaching in the primary school, and how they changed and adapted the knowledge and skills developed at university in a practical situation. The findings of the study are organised by considering what we, the researchers, saw as three categories of challenge for these beginning primary science teachers, their initial alienation from the study of science, the differences between teaching science and teaching other subjects in the primary school, and the impact of novice status on science teaching. Working with participants to help them respond to these challenges became an occasion for our own development as science educators. 相似文献

Background: In Bangladesh, a common science curriculum caters for all students at the junior secondary level. Since this curriculum is for all students, its aims are both to build a strong foundation in science while still providing students with the opportunities to use science in everyday life – an aim consistent with the notion of scientific literacy.Purpose: This paper reports Bangladeshi science teachers’ perspectives and practices in regard to the promotion of scientific literacy.Sample: Six science teachers representing a range of geographical locations, school types with different class sizes, lengths of teaching experience and educational qualifications.Design and method: This study employed a case study approach. The six teachers and their associated science classes (including students) were considered as six cases. Data were gathered through observing the teachers’ science lessons, interviewing them twice – once before and once after the lesson observation, and interviewing their students in focus groups.Results: This study reveals that participating teachers held a range of perspectives on scientific literacy, including some naïve perspectives. In addition, their perspectives were often not seen to be realised in the classroom as for teachers the emphasis of learning science was more traditional in nature. Many of their teaching practices promoted a culture of academic science that resulted in students’ difficulty in finding connections between the science they study in school and their everyday lives. This research also identified the tension which teachers encountered between their religious values and science values while they were teaching science in a culture with a religious tradition.Conclusions: The professional development practice for science teachers in Bangladesh with its emphasis on developing science content knowledge may limit the scope for promoting the concepts of scientific literacy. Opportunities for developing pedagogic knowledge is also limited and consequently impacts on teachers’ ability to develop the concepts of scientific literacy and learn how to teach for its promotion. 相似文献

AbstractTeaching, learning and assessment methods for teaching students about diversity should be transformative and achieve lasting changes in students’ attitudes and behaviours towards diverse individuals. Therefore, dialogue education in the teaching and learning of an undergraduate course in diversity management at a higher education institution was considered as an alternative to existing practices. This article reports on a mixed method study that was conducted to gather data from students over a period of three years. The results of the study indicated that the majority of students did well with the dialogue approach to education except for a small underrepresented group of Indian females: they experienced low levels of self-efficacy in class discussions and presentations, thereby preventing them from benefitting from the educational opportunity offered. 相似文献

Summary This article describes how a teacher changed her method of teaching after acquiring knowledge about graphing calculators in a Professional development program. It describes one particular unit on understanding variables and graph interpretation taught in a seventh-grade science and math class. The use of graphing calculators proved to be effective in increasing student understanding of relationships between variables, graphing, and experimental design. The teacher in our project also found graphing calculators to be effective tools for teaching constructively. Our study implies that math and science teaching can be improved through the use of graphing calculators. 相似文献

Summaries English One of the main aims in the teaching of science is the acquisition of an experimental methodology. The principal obstacles to this methodological training are briefly analysed; they arise mainly from the shortage of time available for experimental work. In this article, computer‐simulated scientific experimentation is proposed as an aid in overcoming these obstacles. This type of teaching, integrated into a classical curriculum, does not exclude laboratory work, which is still indispensable for the learning of techniques. To facilitate the setting up of the proposed method, the ESSOR system simulation on mini‐computer has been developed. Its technical and pedagogic characteristics are described. This system allows the easy simulation of experiments analogous to those of the laboratory. The student using it is free to adopt individual procedures for the study of a proposed phenomenon; the system follows up automatically the individual activity of students and frees the instructor from most of the difficulties in programming work. 相似文献

This article deals with the following question: how can research in science education enrich the design of teaching innovations? Two possible answers are examined:
-
Students’ own ways of reasoning may be taken into account, either as provisional steps towards more elaborate views or as obstacles to be confronted.
-
The epistemological framework of episodes using an experimental set‐up may be used. This can take different forms, ranging from simple inductions to searches for consistency between given laws or hypotheses and experimental facts.
