This introductory activity explores the advantages of different roof shapes for different climates or situations. It addresses questions such as "When you walk or drive around your neighborhood, what do the roofs look like?" and "What if you lived in an area with a different climate, how would that affect the style of roof that you might find?"…

This document presents a sample of the Arkansas science curriculum and identifies the content standards for physical science systems, life science systems, and Earth science/space science systems for kindergarten students. Each content standard is explained and includes student learning expectations, kindergarten benchmarks, assessments, and…

Consistent with the current reform movement in science education, the purpose of this study was to examine how the introduction of an innovative curriculum influenced teachers' beliefs. Six teachers each implemented an Acids & Bases Curriculum Unit in a variety of middle school settings. The teachers were interviewed regarding their beliefs…

Describes a system for remedial assistance with problem solving for first year physics by using synchronized tape-slide materials with provision for control to be exercised by a group rather than by individuals. (PR)

Taken from a paper delivered to a group of Nigerian physicists in 1970 on short-term, long-term, and 5-to-20-year term planning and development of scientific programs. (IR)

Raises questions about the widely accepted rationale of teaching scientific methodology in order to help students become better problem solvers in nonscience settings. Argues that it is better to teach problem solving skills within familiar contexts not complicated by difficult subject matter. (DC)

A large-scale computer managed training program in problem-solving in applied mathematics and basic physics for first-year medical students at the University of Leuven is described. Students do calculations away from the terminals, but are corrected and evaluated at terminals. Some tentative results are presented. (Author/MSE)

Mathematical modelling and an example used with undergraduates were presented in part 1 (v17, n5, p212-18, 1982). A second example, Power from Windmills, is provided which has considerable potential for development both as a model and as a series of modelling experiences of increasing difficulty for students with different backgrounds. (Author/JN)

Suggests a scientific approach for teaching problem solving that would aim at understanding the underlying cognitive mechanisms responsible for good problem solving and would then use the resulting insights to design explicit instructions for enhancing student's problem solving skills. (Author/SK)

Describes the heating of a baby's milk bottle (an exercise in modelling) and the interaction between lecturer and students as they formulate the problem, produce a tentative solution and interpret the solution. (Author/JN)

Discusses laboratory investigations designed to allow students to solve problems without using predetermined mathematical formulas. As a result, laboratory problems force students to think. In addition, some students formulate their own mathematical relationships and enhance their understanding of the connection between mathematics and…

Presents an exercise using linguini noodles to demonstrate an aspect of DNA fingerprinting. DNA maps that show genetic differences can be produced by digesting a certain piece of DNA with two or more restriction enzymes both individually and in combination. By rearranging and matching linguini fragments, students can recreate the original pattern…

Describes chemistry laboratory experiments that can be done with student-designed investigations. Suggests approaches for restructuring traditional chemistry laboratories. (DKM)

Details an investigation concerned with the composition of a grape to illustrate how food and nutrition topics can drive inquiry-oriented science learning. Students design experiments that surround the development of a fictitious new beverage. (DDR)

Analyzes student performance on solution calorimetry problems in an introductory university chemistry class. Includes data from written classroom exams for 207 students and an extensive longitudinal interview with a student. Indicates learning difficulties, most of which appear to originate from failure to understand, that net increases and…
