Chi (1992, 1993) Chi et al. (1994) suggests that many of the difficulties encountered by students in learning Physics concepts arise because they attribute the ontology of material substances to these concepts. These concepts are actually a special type of process - 'Constraint-Based Interactions' (CBI). Slotta and Chi (1996) reported on a study where a group of students explicitly trained in the CBI ontology showed significant gains over a control group in problem solving performance in eight simple electric circuit problems. This paper reports on a series of four studies which explore the usefulness of the ontological categorization framework in investigating students' alternative conceptions of electric circuits and in developing a teaching strategy for promoting conceptual change in the learning of basic electric circuitry concepts. 相似文献

Abstract In this study we describe and examine the effectiveness of an instructional program designed to teach learning disabled adolescents to make better personal decisions. We presented problems in short narratives based on the types of problems these students must solve in their own lives. The program, conducted as part of the students' regular resource room curriculum, incorporated schema‐general questions for problem solving coupled with practice in generating problem‐specific questions to reach an appropriate decision. Participants were 70 resource room students in two large, urban high schools. We employed a pretest‐posttest comparison group design. On the posttest, instructed students performed significantly better on (1) identifying a general schema for making a personal decision and (2) applying the schema to reach appropriate decisions concerning novel problem narratives. The results support the view that application of a general schema to specific problems can be an effective instructional method to improve critical thinking and decision making. 相似文献

In 2013, The Better Image (TBI) was contacted to examine A Play of Selves, a unique work created by artist Cindy Sherman during her graduate studies in 1975. The work is composed of 244 paper doll-like photographs of Sherman that are presented within 72 frames. During initial condition checks, it was noted that a number of individual elements had begun to show signs of chemical staining. Over the course of 2013/2014, a collaborative response was developed with the help of the artist, the artist's printer, the representing gallery, TBI staff and the owner. The main goal was to address the physical and chemical issues present and preserve this work for future exhibition and study. Determining an effective decision- making model based on a hierarchy of values was crucial before undertaking any conservation treatment, as there were several invested parties, each with a different perspective. The focus of this paper is the interplay of our responsibilities as conservators with the concerns of the artist, her gallery, her printer, and the owner to balance aesthetic vs. physical integrity of the artwork, reversibility of treatments, importance of record keeping while developing a balanced response within a world of rapidly disappearing traditional photographic papers. 相似文献

Can research on science learning and instruction inform standards for science education? 总被引:1,自引:0,他引:1

We contrast the current science education reform effort with the reforms of the 1960s and suggest how the current effort could be enhanced. We identify insights from recent research that we believe can inform the reform process, in particular, to reach all science students and also impart a cohesive view of science. We propose an alternative models view of scientific explanation and show how this view would contribute to reforms of (1) course goals, (2) social aspects of science learning, (3) instructional practices, and (4) roles for technology.This paper summarizes discussions and debates that the authors have had over the last few years. The dialogue stems, in part, from our joint participation in the American Educational Research Association Special Interest Group on Education in Science and Technology (AERA SIG:EST) leadership. This paper communicates the spirit of our thinking and does not necessarily reflect the view of SIG:EST, or any other organization.We gratefully acknowledge the support of National Science Foundation Grant MDR-9253462 in work related to this paper.

The following article presents a small-scale qualitative study in which the student learning experiences from service user and carer (SUAC) involvement in social work, mental health nursing and social welfare courses at an English university were evaluated for any effects on student perceptions, knowledge, skills and practice. Using focus group methodology, student participants reported positive outcomes from exposure to SUAC classroom inputs such as a greater valuing of SUAC knowledge as expert knowledge, help with the development of empathy and an appreciation of constructive challenges to mainstream curricular delivery. Notes of caution were identified, particularly in respect of the sometimes unexpected levels of emotion displayed by SUAC presenters. Recommendations for meaningful SUAC involvement in higher education are made regarding the need to involve SUACs across the whole duration of a course; the need for the preparation of both students and presenters regarding boundaries; the fit of presentations with intended learning outcomes; more partnership delivery in classrooms between academics and SUACs (possibly with a differentiation between theoretical and practice inputs); the opportunities for SUACs to present their own situations as real rather than hypothetical case studies for students and the possibilities that may result from introducing a ‘buddying’ system between students and SUACs throughout their studies. It is suggested that the insights from this small-scale study merit further exploration on a larger scale if policy and practice in the field of service and user involvement in higher education are to move forward in an inclusive manner. 相似文献

RESEARCH FINDINGS: The purpose of this study was to examine the relations of children's effortful control and quality of relationships with teachers to school attitudes longitudinally in an ethnically diverse and economically disadvantaged sample. Data were collected as part of a larger intervention project during mid-fall, winter, and late spring (ns = 823, 722, and 758, respectively) for 2 cohorts of 3- to 5-year-olds (collected during 2 different school years). Children's effortful control was assessed in the fall with parents' and teachers' reports and 2 behavioral measures. Teacher-child relationship quality was assessed mid-year with teachers' reports of closeness and conflict. Attitudes toward school were assessed in late spring using teachers' and students' reports of school avoidance and liking. Effortful control, in general, was positively correlated with teacher-child closeness and school liking and negatively correlated with conflict and school avoidance. Using structural equation modeling and controlling for sex and ethnicity, we found that effortful control was positively related to teacher-child relationship quality, which in turn was positively related to school attitudes. Furthermore, the relation of effortful control to school attitudes was mediated by teacher-child relationship quality. PRACTICE OR POLICY: Results provide evidence for the importance of relational processes that take place within the classroom context and have implications for teachers and clinicians working to increase school success in ethnic minority and low-income children. 相似文献

Early childhood teacher educators frequently enhance their teaching by reading children’s books to their adult students. It
is not unusual for faculty outside of early childhood to question devoting precious class time to read-alouds which they may
consider a curious, if not frivolous, instructional strategy. Quality children’s literature can, however, enhance students’
experiences in the college classroom, contribute to their understanding of course content, promote their personal growth and
self-understanding, increase their appreciation for quality children’s literature, and enhance their ability to integrate
storybooks into their own teaching. Children’s books often capture a child’s point of view. They have the potential to provide
historical or cultural perspectives on children and families. They also can lead to the examination of universal truths and
can facilitate the discussion of sensitive or emotional issues A list of books with suggested uses is included. 相似文献
