Explains that, to teach students how to solve problems, defining the problem should be the focus, and the skills to solve the problem should be analyzed. Differentiates between exercises and real problems. (PR)

Carries on from an article about the context for assessment of problem solving skills. Describes other forms of evidence in problem solving skill besides the options given in the previous article. Lists eight forms of evidence related more directly to the problem solving process. Analyzes the relationship among some of these suggested forms of…

Describes differences in modes of thinking between natural sciences and engineering practitioners and presents a study investigating the differences in how engineering and chemistry faculty approach problem solving. (YDS)

An ARO/Rh Blood-Typing kit useful for students to visualize blood-typing activities and practice problem-solving skills with transfusion reactions is presented. The model also enables students to identify relationships between A, B, and Rh antigens and antibodies in blood and to understand molecular mechanisms involved in transfusion agglutination…

Problem-solving is one of the main goals in science teaching and is something many students find difficult. This research reports on the development, implementation and evaluation of a problem-solving heuristic. This heuristic intends to help students to understand the steps involved in problem solving (metacognitive tool), and to provide them…

This article examines issues that arise from learning and knowledge in technology education. The issues examined are, first, the definition of technological knowledge and what the nature of that knowledge should be, where the concern is with "how" we define and think about that knowledge, especially in the context of how students learn and use…

In this article, the author describes how middle schools can prepare young people for the challenges and opportunities of the 21st century. Integrating 21st century skills deliberately and systematically into middle school education will empower educators to accomplish many of the elusive goals they have tried to reach for years. Twenty-first…

This paper examines the intersection between creativity, problem solving, cognitive psychology and neuroscience in a discussion surrounding the genesis of new ideas and innovative science. Three creative activities are considered. These are (a) the interaction between visual-spatial and analytical or verbal reasoning, (b) attending to feeling in…

In an era in which time is more compressed than it has ever been before, the life cycle of any innovation is extremely brief, and an unexpected, bold idea that is quickly put to work in the sphere of virtual reality can result in a "super-breakthrough" in the world of new industrial technologies. In order to accomplish cutting-edge…

In this article, the authors discusses Visualization in Technology Education (VisTE). VisTE units are designed to enhance students' knowledge in science, develop good visual and presentation skills, understand emerging technologies, and most of all help with the integration of standards that promote technological literacy. Technological changes…

The purpose of this study was to increase the science education community's understanding of the experiences and needs of girls who cross the traditional categorical boundaries of gender, race and socioeconomic status in a manner that has left their needs and experience largely invisible. A first of several in a series, this study sought to…

Many terms such as "balance of nature" and "pollution" are metaphors that are used in many courses. We should analyze terms we plan to use in courses and avoid the use of terms such as "pollution" if we desire to stress rational thinking. (RH)

In a previous study (Watson, 1960), college students were told that a three-number string ("2, 4, 6") conformed to a rule and that they had to guess the rule by proposing other three-number strings; they were then told whether each guess was right or wrong. However, it was suspected that, since the subject's hypothesis was falsified by…

Examined the problem-solving performances of novices (11 undergraduates) and experts (9 graduate students and instructors), comparing them in terms of background expertise and problem-solving success. Also examined problem-solving behaviors reported in other domains and determined whether or not genetics is a fruitful area for problem-solving…

Human expert problem-solving in science is defined and used to account for scientific discovery. These ideas are used to describe BACON.5, a machine expert problem solver that discovers scientific laws using data-driver heuristics and "expectations" such as symmetry. Implications of BACON.5 type research for traditional science education…
