Introduces the peanut observation activity to teach about the pros and cons of dissection. As an inquiry-based approach, dissection is one way to teach process skills. Lists the progression of the activity as observation, questioning and finding the answer, challenge, discussion, and further examination. (Contains 12 references.) (YDS)

Reports on a study undertaken to develop research rubrics for a performance assessment of science processes and evaluate seventh-grade science students' ability to perform them. Focuses on the processes of recording data, analyzing data, drawing conclusions, and providing evidence. Reports that only 61% of the students performed the activity and…

Analyzes group discourse (n=24) during laboratory investigations in order to understand how students solve scientific problems and the ways social roles shape the development and articulation of arguments. Results indicate that knowledge building depends on students learning to use tools of the scientific community and the social context in which…

Describes a unit that gives students an opportunity to write while actively exploring the scientific concept of magnetism. Provides students with a framework for recording their learning and gives teachers a method for observing how well students actually understand and can apply the knowledge they acquire. (JRH)

Proposes that a game called Black Box is a useful tool for introducing various features of scientific reasoning to introductory research methods classes. Outlines the rules of the game and suggests analogies that instructors can make between the game and concepts commonly mentioned in discussions of scientific reasoning. (DSK)

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…
