Compares a group of expert cancer researchers with four groups of fourth year medical students (the "novice" groups) engaged in the task of designing a clinical trial to test a new cancer drug using a computer-based modeling tool, the Oncology Thinking Cap. (Contains 24 references.) (Author/YDS)

Introduces a tornado tube activity to develop understanding of an environmental phenomena. Uses an inquiry-based, hands on science approach. (Contains 24 references.) (YDS)

Suggests an approach to teaching vectors that promotes active learning through challenging questions addressed to the class, as opposed to subtle explanations. Promotes introducing vector graphics with concrete examples, beginning with an explanation of the displacement vector. Also discusses artificial vectors, vector algebra, and unit vectors.…

Describes a simple time-of-flight experiment using readily available equipment. The method of measuring the speed of light uses a modulated laser and introduces students to some concepts of optics, measurement of very small time intervals, modulation of lasers, waveform generation, fast detectors, and data processing. (Contains 20 references.)…

Presents the floral foam activity which explores the relationship between volume and mass. Focuses on helping students to enhance their critical thinking skills. (YDS)

Explores high school students' collaborative efforts in solving qualitative physics problems and investigates how and whether confronting students with varying views improves problem solving skills. (Contains 22 references.) (DDR)

The current study describes an authentic learning experience designed to develop technology and science process skills through a carefully scaffolded curriculum using mealworms as a content focus. An individual mentor assigned to each 4th and 5th grade girl participating in the program delivered the curriculum. Results indicate mastery of science…

Spring is an exciting time in any kindergarten classroom. The children are communicating better, and they have begun working more independently. Their critical-thinking skills are growing each day. Last year, as the warm days of spring teased our senses, a plant unit seemed especially enticing, so the author created four interactive, plant-themed…

Young children do science exploration and observation every day in their play. They spontaneously engage in parts of the scientific inquiry process--wondering, asking a question, planning how to answer the question, documenting their work, thinking about what happened, and sharing their results with others. Conducting an entire experiment is…

Every day the media bombards the nation with concern over childhood obesity. More American children than ever before are developing health problems related to their eating habits and lack of exercise. The classroom is the perfect place to deal with this national crisis by speaking directly to the children. If children could become more aware of…

Although every student must take some science courses to graduate, understanding the process of science is important, and some students never seem to really grasp science. The National Science Education Standards stress process as a major component in science instruction. The standards state that scientific inquiry is basic to science education…

In this study, an interactive process in a Web-based learning environment was planned for the cultivation of students' cooperative learning skills and capacity for scientific inquiry. Based on detailed analyses of students' computer protocols, interview protocols, and test scores, this project sought to analyze the changes in students' scientific…

Most primary science practitioners would immediately list questioning as one of the key ways in which they influence children's learning. Even so, effective questioning is not a straightforward skill. In this article, the author offers ideas to help practitioners understand the relevance and importance of questioning in primary science and how…

The computer numerical control (CNC) flatbed router is a powerful tool and a must-have piece of equipment for any technology education program in which students will produce a product--whether it involves Manufacturing, Materials Processing, or any of the vast array of Project Lead the Way courses. This article describes an activity--producing a…

Creating activities that model engineering design as it appears in industry provides great experience for technology students. Design in general creates an element with special regard to its form and function. Engineering design involves doing that, and going beyond to produce an efficient product that addresses its intended purpose. In this…
