A University of Toronto pharmaceutics course which organizes information about physical chemistry around real problems, presented as case studies or laboratory projects, is described. Problems were addressed in class discussions or by unsupervised eight-student groups using self- and group evaluation procedures. Results are discussed, and three…

Describes five skills underpinning the understanding of geometry for primary and lower secondary mathematics students. Skill categories identified include (1) visual; (2) verbal; (3) drawing; (4) logical; and (5) application. Gives examples of skills appropriate for Van Hiele levels 1-3. (MDH)

Presents a series of four worksheets to develop students' perception of spatial relationships. The tasks require students to use cubes to build models and describe the models by representing the front, right, and top views on grid paper. Provides reproducible worksheets. (MDH)

In 1987, National Science Teachers Association commissioned the Search for Excellence in Biology Teaching Task Force. This article is a distillation of the task force report, highlighting the criteria for excellence in biology teaching, grades 7-12. The criteria for excellence are in five subsections: Goals, Criteria for Curriculum, Criteria for…

An age-dependent answer-selection sequence of answers on multiple-choice tests suggested by previous studies was supported using statistical rather than clinical means. Results with 2,810 students aged 88 months through 241 months given a reading comprehension test twice during a 5-month interval support the systematically connected age-dependent…

Proposes using student projects to show students how mathematics can be applied to their lives by using statistics. Students identify a topic of interest to them and their community, collect data, discuss the analyzed data in a written report, and present the reports at the local senior-citizen center. (MDH)

Presents activities to supplement lessons on length and mass measurement or as part of a unit on atoms or orders of magnitude. Provides a lesson plan using aluminum foil to estimate unit measures, calculate the foil's thickness, and do an atom count. (MDH)

Provides a brief explanation why instruction designed for use with the microcomputer can enhance students' understanding of the concept of function. Presents five lessons designed to help students develop a thorough understanding of functions and their uses, to encourage students to explore and verbalize mathematical ideas, and to assist in the…

Identified and classified solution strategies of (n=49) 10th-grade students who were presented with linear programming problems in a predominantly visual setting in the form of a computerized game. Visual strategies were developed more frequently than either algebraic or mixed strategies. Appendix includes questionnaires. (Contains 11 references.)…

Briefly explores the issue of conflict resolution (CR) in education; the introduction of CR into the public schools; and whether CR processes such as mediation meet the needs of nondominant groups. It also introduces several articles that discuss specific approaches to the development and implementation of CR programs in schools. (GLR)

Discusses whether the current trend toward implementing conflict-resolution (CR) programs in schools promotes social justice or supports an inequitable, systemic status quo. The authors also examine the relationships between the educational mission of schools and the concept of social justice and CR's impact on school culture and community. Issues…

Reports on conceptual understanding and solution strategies for percent problems of (n=31) students representing 2 ability levels from grades 5, 7, 9, and 11. Strategies evolved from intuitive to formal and increased in diversity with increasing age. Appendix includes concept and computation interview questions. (Contains 15 references.) (MKR)

Detection of calculation errors, operation errors, and unanswerable problems was studied for 78 third graders and 77 fifth graders. The relationship between mathematics achievement and error detection was also examined. Older children and high achievers detected more errors than did younger students and low achievers. (SLD)

Discusses the changing nature of our world, particularly in regard to the technical revolution. Considers the effects of the changing world on primary education. Maintains that young students in our changing world share basic curricular needs regardless of where they live. (BB)

Discussion of spatial skills focuses on a quasi-experimental field study that was designed to test the possibility that elementary and secondary school library users' success in stack searches could be related to a particular spatial skill, i.e., the ability to solve large-scale mental-rotation and perspective-taking problems.
