Reform efforts are often unsuccessful because they failed to understand that teachers play a key role in making educational reforms successful. This paper describes a long‐term teacher professional development (PD) program aimed at educating and training teachers to teach interdisciplinary topics using case‐based method in science. The research objective was to identify, follow and document the processes that science teachers went through as they assimilated the interdisciplinary, case‐based science teaching approach. The research accompanied the PD program throughout its 3‐year period. About 50 teachers, who took part in the PD program, were exposed to an interdisciplinary case‐based teaching method. The research instruments included teacher portfolios, which contained projects and reflection questionnaires, classroom observations, teacher interviews, and student feedback questionnaires. The portfolios contained the projects that the teachers had carried out during the PD program, which included case studies and accompanying student activities. We found that the teachers gradually moved from exposure to new teaching methods and subject matter, through active learning and preparing case‐based team projects, to interdisciplinary, active classroom teaching using the case studies they developed. 相似文献

For an educational reform to succeed, teachers need to adjust their perceptions to the reform’s new curricula and strategies
and cope with new content, as well as new teaching and assessment strategies. Developing students’ scientific literacy through
context-based chemistry and higher order thinking skills was the framework for establishing a new chemistry curriculum for
Israeli high school students. As part of this endeavor, we developed the Taste of Chemistry module, which focuses on context-based chemistry, chemical understanding, and higher order thinking skills. Our research
objectives were (a) to identify the challenges and difficulties chemistry teachers faced, as well as the advantages they found,
while teaching and assessing the Taste of Chemistry module; and (b) to investigate how they coped with teaching and assessing thinking skills that include analyzing data from
graphs and tables, transferring between multiple representations and, transferring between chemistry understanding levels.
Research participants included eight teachers who taught the module. Research tools included interviews, classroom observations,
teachers-designed students’ assignments, and developers-designed students’ assignments. We documented different challenges
teachers had faced while teaching the module and found that the teachers developed different ways of coping with these challenges.
Developing teachers’ assessment knowledge (AK) was found to be the highest stage in teachers’ professional growth, building
on teachers’ content knowledge (CK), pedagogy knowledge (PK), and pedagogical-content knowledge (PCK). We propose the use
of assignments designed by teachers as an instrument for determining their professional growth. 相似文献

The goals of this study were to compare self‐perceptions of self‐efficacy, mood, effort, and hope between 123 adolescents with learning disabilities (LD) and a group of 123 Non‐LD peers, who were matched for their level of academic performance and gender, and to explore the relations between measures of self‐perception and achievement. The results showed that students with LD reported lower academic self‐efficacy and lower social self‐efficacy. They also rated their mood as more negative and reported lower levels of hope and less investment of effort in their academic work. At the same time, no significant differences were found for emotional self‐efficacy in comparison to the Non‐LD peer group. In addition, among students with LD who were successful in their studies, a subgroup continued to report low levels of hope. The results demonstrated that even when the academic performance of students with LD is similar to their Non‐LD peers, their specific and global self‐perceptions continue to reflect their distress. It is not clear if these results represent past difficulties, day‐to‐day struggles, and/or future worries. Resilience models are proposed and research limitations are specified. 相似文献

Understanding of Earth’s systems, including the crucial role of human beings within them, is an important part of citizens’
ability to think intelligently and critically about the environment, pollution, sustainability and other socio-economic and
scientific issues central to life in the modern world. Part of this understanding involves seeing the world as an integrated
whole in which what happens in diverse places in the world may be equally relevant for students' lives. In this regard, it
makes sense to study both remote and local environments within the system thinking approach—where such distinctions naturally
become blurred. The present research, accordingly, focuses on a study unit entitled “Life at the Poles” and investigates the
development of junior high school students’ understanding of Earth systems and their level of conceptual complexity as a result
of participating in it. The “Life at the Poles” unit is based on the “explanatory story” approach where one central theme
is used as a focal point for an interdisciplinary study of certain natural phenomena, in this case, the possibility of life
under the extreme conditions at the poles. Concept maps and Likert-type questionnaires were employed as research tools, allowing
the collected data to be analyzed both qualitatively and quantitatively. The research findings indicate that the students
significantly improved their Earth systems understanding and, importantly, greatly increased their awareness of human beings’
influence on the environment, including remote environments such as the pole. 相似文献

This article is an attempt to place mathematical thinking in the context of more general theories of human cognition. We describe
and compare four perspectives—mathematics, mathematics education, cognitive psychology, and evolutionary psychology—each offering
a different view on mathematical thinking and learning and, in particular, on the source of mathematical errors and on ways
of dealing with them in the classroom. The four perspectives represent four levels of explanation, and we see them not as
competing but as complementing each other. In the classroom or in research data, all four perspectives may be observed. They
may differentially account for the behavior of different students on the same task, the same student in different stages of
development, or even the same student in different stages of working on a complex task. We first introduce each of the perspectives
by reviewing its basic ideas and research base. We then show each perspective at work, by applying it to the analysis of typical
mathematical misconceptions. Our illustrations are based on two tasks: one from statistics (taken from the psychological research
literature) and one from abstract algebra (based on our own research).

How do undergraduate students cope with abstract algebra concepts? How should we go about researching this question? Based on interviews with undergraduate students and on written questionnaires, a theoretical framework evolved which could coherently account for most of the data. According to this theoretical framework, students' responses can be interpreted as a result of reducing the level of abstraction. In this paper, the theme of reducing abstraction is examined, based on three interpretations for levels of abstraction discussed in mathematics education research literature. From these three perspectives on abstraction, ways in which students reduce abstraction level are analyzed and exemplified. 相似文献
