Discusses research into problem-solving skills that have caused the theoretical methods of teaching and learning problem solving to evolve rapidly. Presents issues and questions that still need to be explored. (PR)

Outlines how a group of primary teachers developed a range of design briefs using textiles, and describes how students were taught explicit skills which enabled them to successfully solve the design tasks. (WRM)

Suggests that simple riddles can be used effectively to make students interact in science class. Proposed teaching methods require the student to provide answers to riddles in order to develop the discussion about a given topic. Presents sample riddles related to elements and their compounds. (WRM)

Describes the nature and existence of both model-data fit and conceptual problems in science, then examines two curricular projects--one in genetics and one in evolutionary biology--that attempt to integrate these problems into classroom instruction. (Author/SAH)

Evaluates an instructional method in general chemistry that attempts to bridge the gap between algorithmic problem-solving abilities and conceptual understanding of chemistry students and emphasizes conceptual problem solving in the initial phase of a concept. Concludes that using a conceptual focus for the chemistry courses had many positive…

Introduces the "Where are We?" software and lessons that are designed to help children in grades 2-4 learn to translate between the visually-perceived world that they sense around them, and the schematic representation of that landscape on a map. Evaluates the skills practiced in the software. (Contains 26 references.) (Author/YDS)

Describes a contest in which students attempt to build a device that produces a donut-shaped air pulse that will travel the greatest distance with the most accuracy. (WRM)

Describes an experiment undertaken to determine what relative electric charges would result if three or more pieces of transparent tape were placed on top of each other and then separated one at a time. Makes suggestions for using the project in high school and undergraduate classes. (WRM)

Discusses Newton's long struggle with the concepts of inertia and centrifugal force as an example of high-grade scientific thinking. Discusses the role of textbooks and how they largely emphasize memorization. Suggests that the historical approach can be more time-consuming than textbook-based teaching and that it requires a good understanding of…

Presents an activity that allows students to apply problem-solving skills and chemical principles to calculate the cost for converting a gasoline-powered vehicle to propane. (Author/ASK)

How can teachers make science learning relevant to today's technology savvy students? They can incorporate the Internet and use it as a tool to help solve real-life problems. A group of university professors, a field biologist, and classroom teachers teamed up to create an exciting, interactive Web-based learning environment for students and…

A simple circuit problem treating an inductor, resistor and battery in series has uncovered a basic misconception of first-year students. The misconception is not about circuits or electrical properties but concerns rather the meaning and interpretation of the rate of change (instantaneous slope or derivative) of physical quantities. Resolving the…

Giving students good feedback on all their schoolwork is one of the toughest challenges every teacher faces. But here at last is a guide that helps you always know how to give the right feedback for all kinds of assignments, in every grade level and subject area. Susan M. Brookhart covers every possible aspect of the topic, including: (1) What…

In this study, we discuss the scaffolded design of ODRES (Observe, Discuss, and Reason with Evidence in Science), a computer tool that was designed to be used with elementary school children in science, and report on the effects of learning with ODRES on students' conceptual understandings about light, color, and vision. Succinctly, dyads of…

Modeling has been shown to correct weaknesses of traditional instruction by engaging students in the design of physical models to describe, explain, and predict phenomena. Although the modeling method can be used without computers, the use of computers allows students to study problems that are difficult and time consuming, to visualize their…
