Instructors are constantly baffled by the fact that two students who are sitting in the same class, who have access to the same materials, can come to understand a particular chemistry concept differently. Variation theory offers a theoretical framework from which to explore possible variations in experience and the resulting differences in…

The discipline of education is a multi-faceted system that must constantly integrate new strategies and procedures to ensure successful learning experiences. Enhancements in education provide learners with greater opportunities for growth and advancement. "Open Learning and Formal Credentialing in Higher Education: Curriculum Models and…

To practice effectively, one must first know how to practice. The practice process is affected by one's ability to set goals, design strategies, self-assess, and to have an aural image of the music being learned. The author proposes a model reflecting the factors involved in practice and proposes a number of strategies that can be used to…

For the past five summers, the authors have taught summer school to recent immigrants and refugees. Their experiences with these fourth-grade English language learners (ELL) have taught them the value of using models to build scientific and mathematical concepts. In this article, they describe the use of different forms of 2- and 3-D models to…

We used four different methods to determine the best means of assessing over 200 preservice elementary teachers' growth in knowledge of models and their use in K-8 classrooms while participating in the Science Capstone course that focused on the unifying themes of models in science. Each assessment method probed a different aspect of models (from…

Since Widodo, Duit and Muller (2002) addressed that there is a gap between teacher's theoretical knowledge and their practical classroom constructivist behavior, we presented a sample teaching activity about Endothermic-Exothermic Reactions for teacher usage. Therein, the aim of this study is to design a 5E model to include students' alternative…

Describes a three-step process to help teachers honor what children bring to each reading situation and to model for children the importance of accessing appropriate knowledge sources before reading. (FL)

This report describes the role of analogies in science instruction and presents research on a model for teaching with analogies. This model is being developed from research studies of textbooks and exemplary teachers; it provides guidelines for the strategic use of analogies during science instruction to explain fundamentally important concepts in…

This study describes the multiple analogical models used to introduce and teach Grade 12 chemical equilibrium. We examine the teacher's reasons for using models, explain each model's development during the lessons, and analyze the understandings students derived from the models. A case study approach was used and the data were drawn from the…

Designed to provide specific instructional suggestions for integrating basic reading and writing instruction in the elementary school, the lesson ideas presented in this booklet are applicable across grade levels and can be used with any basic reading and language arts textbook series. The 30 ideas cover a variety of areas, including the…

Earth science teachers know how frustrating it can be to spend hundreds of dollars on three-dimensional (3-D) models of Earth's geologic features, to use the models for only a few class periods. To avoid emptying an already limited science budget, the author states that teachers can use a simple alternative to the expensive 3-D models--sand. She…
