An activity in which students use manipulative materials to help solve simple algebraic equations using the operations of adding inverses, removing opposites, and sharing equally is presented. Directions, examples, the rationale, and cautions are included. (KR)

The idea that the methodologies provided by research should serve as models in developing practices in the classroom and in finding adequate solutions to students' and society's problems is discussed. The thoughtfulness of science, the scientific method, and science teaching are included. (KR)

An astrophysics course based on the constructivist approach to science teaching is described. The study of galactic structure is given as an example. Direct experiences and observations, representative-symbolic language, organized knowledge, and formal strategies are emphasized. (KR)

An integrated lesson for kindergarten that familiarizes students with the phases and the surface of the moon is provided. Activities allow students to draw comparisons between the surface of the moon and the earth. Questions to ask students, directions for the activities, and a list of needed materials are included. (KR)

Described is a programing application of the software, Mathematica, which allows students to explore the various cases involved in minimizing the sum of squares for the best fit of a regression line. Several examples are included with appropriate software commands. (JJK)

Student comments about having time in class to think and solve problems are presented. Stressed are teaching methods which allow students to familiarize themselves with the problem, think about solution processes, work through the solution process, and reflect while solving a problem. (CW)

Discussed are teaching methods that can be used in association with amusement park rides. The basic principles behind the effects of several rides are reviewed and illustrated. (CW)

Revoicing as a classroom technique is considered. Three examples illustrate the potential of the classroom discourse strategy revoicing to position students with regard to propositions and allow them to claim or reject the positions; share reformulations to credit students with teacher inferences; and scaffold and recast problem-solution…

Provides guidelines for classroom discussions of bioethical issues. Equipped with an ethical reasoning model, teachers can help to prepare students to make responsible decisions about science-related issues. (ZWH)

Defines critical thinking and provides a practical approach to applying it to teaching physical education (PE). Critical thinking in PE can result in improved skills, fitness, and knowledge. Examples of the kinds of questions and challenges appropriate for a critical thinking lesson in PE are provided. (SM)

Describes the interactions and applications of three models of learning: Bloom's taxonomy, the Jungian or Myers-Brigg's Typology, and William Perry's model of attitude toward learning. (PR)

Examined the differential effects of two instructional strategies (explicit schema-based and traditional-based) on the acquisition, maintenance, and generalization of mathematical word problem solving among elementary students at risk or with mild disabilities. Pretesting and posttesting indicated that both groups' performance increased from…

Describes how Problem-Based Learning (PBL) was adapted for use in social studies teacher education. Reviews the background of PBL as used in professional faculties, and offers curricular justification for its use. Examines difficulties experienced in adapting PBL to teacher education, taking into account perspectives from prospective teachers and…

Discusses strategies for teaching social skills to children with learning and behavior problems, including how to select students for training, which social skills to use, teaching discrete skills and problem-solving routines, and helping students generalize training. Different types of social skills and assessment approaches are identified.…

Two experiments involving 90 primary and intermediate-grade students studied how the COPPERS computer-based mathematical learning environment advances children's understanding that multiplication problems have many different correct solutions. Factors affecting learning and theoretical implications are discussed in terms of scaffolding learning.…
