This standard lesson on identifying salt and sugar crystals expands into an opportunity for students to develop their observation, questioning, and modeling skills. Although sugar and salt may look similar, students discovered that they looked very different under a magnifying glass and behaved differently when dissolved in water. In addition,…

Collaborating closely with a 10th-grade science teacher, we designed a Web-based learning environment (Web-LE) to improve student motivation to learn science. Factors believed to enhance intrinsic motivation (challenge, control, curiosity, and fantasy) were integrated into the instructional design of the Web-based learning tool. The Web-LE was…

Understanding the basic principles of structural biology is becoming a major subject of study in most undergraduate level programs in biology. In the genomic and proteomic age, it is becoming indispensable for biology students to master concepts related to the sequence and structure of proteins in order to develop skills that may be useful in a…

The Arizona Collaborative for Excellence in the Preparation of Teachers (ACEPT) Program is one of several reform efforts supported by the National Science Foundation. The primary ACEPT reform mechanism has been month-long summer workshops in which university and community college science and mathematics faculty learn about instructional reforms…

Chemistry learning involves establishing conceptual relationships among macroscopic, microscopic, and symbolic representations. Employing the notion of intertextuality to conceptualize these relationships, this study investigates how class members interactionally construct meanings of chemical representations by connecting them to real-life…

South Africa is a multilingual country with 11 official languages. However, English dominates as the language of access and power and although the Language-in-Education Policy (1997) recommends school language policies that will promote additive bilingualism and the use of learners' home languages as languages of learning and teaching, there has…

The departments of mathematics, biology, and chemistry and the teacher education program at the College of Saint Elizabeth (New Jersey) are working in partnership with a public school to improve the teaching of mathematics and science in preschool through high school levels and to recruit minority science and mathematics teachers. The program aims…

This training manual is intended to enable educators to utilize the SAGE Tri-Fold Model as a means for developing a process-oriented differentiated curriculum for elementary grade gifted students using either the separate classroom, the resource room, or the consultant teacher model. The program, a nationally validated National Diffusion Network…

In response to the poor achievement, negative attitudes, and anxiety of limited-English-proficient (LEP) ninth-grade students (n=90) in science classes, a cooperative learning approach to instruction was adopted. In an effort coordinated with teachers of English for Speakers of Other Languages (ESOL), the students were assigned to cooperative…

This study examined the moral values embedded in the instruction and practice of higher education, focusing on instruction within three disciplines at a mid-sized residential university in the Pacific Northwest over the course of three semesters. Through classroom observations and transcriptions of tapes of classroom interaction in 46…

Science process skills include basic skills like observing, inferring, measuring, communicating, classifying, and predicting, as well as integrated skills like controlling variables, defining operationally, formulating hypotheses, interpreting data, experimenting, and formulating models. Recognition of the value of science process skills has…

This Dwight D. Eisenhower Mathematics and Science Education in-service project in northwest Indiana, based on a contextual constructivist perspective, sought to enhance science learning by improving science teaching in grades K-8. Elementary and middle school teachers from urban, suburban, and rural public and parochial schools attended a summer…

This book was written on the premise that learning science should be fun and rewarding. The teacher may use it as the foundation for an extended middle school curriculum spanning more than one year or to supplement an existing curriculum with individual sections or exercises from the book. The activities have been organized and designed in a…

This paper describes the task analysis of performance-based science tasks that were designed for the 1994 National Assessment of Educational Progress (NAEP) science assessment, now postponed until 1996, and field tested in 1993. A brief description of the science performance tasks is followed by a description of the task analyses performed and a…

This document presents the framework of standards in New York state for mathematics, science, and technology at elementary, intermediate, and commencement levels. This revised edition incorporates changes to the content standards and performance indicators based on extensive review by the public. As educational practice improves, these standards…
