This paper documents the dynamics of the social interactions within two small groups of sixth grade students as they solved problems and attempted to understand the concepts related to the nature of matter and molecular theory. Similarities and differences of social interactions between the two groups are compared, and interpretations presented…

This paper describes two studies designed to examine the effect of instructional analogy training on the level of comprehension of 10 advanced physiological concepts. In the first study, 161 college students received instruction either with or without analogies. Levels of student performances were compared across three conditions: (1) concept…

This paper describes how visual media technologies have been used to support research into the way technical diagrams are represented in people's minds. Two groups of subjects participated in this research, individuals with either a high or a low level of expertise in meteorology, specifically professional meteorologists and non-meteorologists.…

Models and modeling are frequently used as instructional tools in science education to convey important information concerning both the explanatory and structural features of topic areas in science. The efficacy of models as such rests almost entirely upon students' ability to conceptualize them as abstracted "representations" of…

This paper describes an instructional method designed to increase opportunities for students to learn and practice appropriate social skills. The strategies for development and implementation of such structured programs of nature-based and animal-based activities are based in part on a pilot program in three urban elementary and middle schools.…

A study examined the role that an elaborate analogy can play when high school students learn a concept from a leading science textbook. The elaborate analogy had graphic and text components that integrated and mapped key features from the analogy (a factory) to the target concept (an animal cell). The target features were parts of the cell and, by…

This paper documents how eight high school students in a precalculus class enhanced with graphing calculators think about functions. Three models of thinking about functions emerged from students' function images observed over a period of 9 months. In the graph model, students believed that functions are essentially graphs; in the equation model,…

This study investigated whether the van Hiele model accurately describes the geometric thinking of gifted students in the 6th through 8th grades prior to a formal course in geometry and made comparisons with what has been found with other populations. The results from 120 students who completed a 25-item multiple choice paper-and-pencil test,…

At issue in this study was the extent to which large numbers of classroom teachers were able to implement research-based materials with a minimum of inservice education. Also at issue was whether students of these teachers were able to develop the rich mental images for fractions similar to the ones students from previous Rational Number Project…

Traditionally, civic education has been introduced at the eighth grade level. Research indicates that youngsters begin learning political information and attitudes much earlier. With that in mind, this publication is designed around concepts that can be developed throughout the primary and intermediate grades. Elementary students can begin to…

This study was conducted to develop a set of concepts regarding teachers' perspectives on accountability, to present exemplars and discussion of each concept, and to analyze implications of the concept for classroom practice. Data were collected through semi-structured interviews with 18 experienced elementary and high school teachers. Two pilot…

This paper describes the implications of constructivism both for what to teach and for how to teach. The first part discusses three approaches on what to teach: (1) relating mathematical knowledge to other knowledge; (2) checking for self-consistency; and (3) putting thinking before facts. The second part is on how to teach based on…

The relationships among prior knowledge, learning strategy use, interest, learning goals, and conceptual understanding were studied with 72 fifth graders from 3 science classrooms. In September 1996 students completed a knowledge test designed to assess their prior knowledge and conceptual understanding of ecological concepts (plant and animal…

This book serves as a guide for overcoming the challenge of improving schools. It provides a comprehensive view of issues related to serious school reform and describes appropriate attitudes, concepts, and tools needed to rethink and redesign American education. A 5-year study of 10 schools in the Coalition of Essential Schools already involved in…

The development of appropriate science learning environments for young children is an urgent and justifiable concern of many. By applying combined features of cooperative learning and informal inquiry to an investigation of shadow formation, researchers were able to observe closely the natural behaviors adopted by twenty-seven students aged 7-9…
