Presents a project that addresses several components of the Algebra and Communication Standards for Grades 9-12 presented in Principles and Standards for School Mathematics (NCTM, 2000). Describes doing mathematical modeling and using the language of mathematics to express a recursive relationship in the perimeter and area of the Koch snowflake.…

Discusses the nature of tasks used to elicit the development of such systems by middle school students. Analyzes mathematical reasoning development of students across tasks and the diversity of thinking patterns identified on problem tasks. Discusses student reasoning about the relationships between and among quantities and their application in…

Presents a case study in which two 8th grade students developed knowledge for modeling a physical device called a winch. Demonstrates that students have and can use criteria for evaluating algebraic representations. Explains how students can develop modeling knowledge by coordinating criteria with knowledge for generating and using algebraic…

Supports the use of a science experiment option in the high school curriculum to enhance student learning. Presents a science experiment rubric and connects the use of science projects with standards. (DDR)

States that recent research suggests that an education in theater beginning in kindergarten and continuing throughout the educational process can teach students valuable skills that will serve them well in the professional world, including problem solving, team work, and decision making. Discusses the program at Jefferson High School and its…

Explains the organization, structure, and assessment of the undergraduate course entitled Clinical Anatomy and Anatomical Skills. The course aims to refocus, vertically integrate, and revise the subject using problem-solving methods plus testing of various clinically relevant skills recorded in a logbook. This report re-emphasizes the importance…

Explores the question of the existence and usefulness of supposed general functions of the mind and the extent to which such functions might be educable. Focuses on the role of education, science education for general development in particular. Contains 99 references. (JRH)

Tested hypothesis that higher levels of positive affect and lower levels of negative affect would predict depression during pregnancy and in the postpartum period. Analysis of 100 women indicated that women at risk for depression during pregnancy and in the postpartum period may exhibit heightened negative moods and a dearth of positive affective…

Maternal instructional behavior at home and maternal ratings of children's temperament when children were 18 months old predicted mothers' problem-solving behaviors and children's performance on a cognitive problem-solving task at 30 months. Mothers' cognitive assistance to children during tasks at 18 and 30 months predicted children's cognitive…

Presents many ideas regarding activities that can be used in science club meetings. Includes hints to problem solvers, problems to solve, ideas for competitions, and an interdisciplinary section about imaginary science. (DDR)

Presents a conceptual model of strong school-based interventions. Notes strong interventions are ecological in nature, naturalistic in scope, contain elements from the research base that are predictive for success, and incorporate the constructs of social validity in a practical manner. Provides suggestions and implications for strong school-based…

Discusses the positive value of conflicts and describes a six-step program, Teaching Students To Be Peacemakers, that instructs students in how to negotiate and mediate conflicts. Reviews research on the effectiveness of the program and the benefits of self-regulation for school discipline programs. Provides steps on how to structure academic…

Explores how teacher collaboration can be expanded to include curriculum considerations. Describes a curriculum-centered collaboration process by which teachers can work together to solve specific classroom problems. Provides vignettes to illustrate each phase of the process. Also addresses curriculum-centered collaboration for broad-based…

Explores the use of simulations as a teaching method for gifted students. Identifies positive effects of simulations and distinguishes different types. Notes disadvantages related to time, money, and experience as are unique features of the teacher's role in this approach to instruction. Lists guidelines for choosing a model and deciding on a…

This paper advocates a philosophy of science teaching that embraces intellectual conflict, suggesting that it is important to engage students in productive intellectual conflict in order to teach for conceptual change. Presents two approaches that could actualize the philosophy of "teaching the conflicts" within science instruction. (SM)
