Many students enter high school with some science knowledge and experience doing investigations but often know little about the nature of science (NOS) or how the knowledge is developed (i.e., science practices). As science teachers, we need to get students excited about science as quickly as possible with activities that introduce the practices…

Middle school students often struggle when writing testable problems, planning valid and reliable procedures, and drawing meaningful evidence-based conclusions. To address this issue, the author created a student-centered lab handout to facilitate the inquiry process for students. This handout has reduced students' frustration and helped them…

The "What's the "matter" With XOD" activity addresses students' misconceptions and refines their ideas about phases of matter. This activity introduces the characteristics for solids, liquids, and gases, and begins a discussion about physical and chemical changes and how matter can cycle through different phases. Depending on class size and…

With the 2010 Winter Olympic Games prominent in the media, children were exposed to images of athletes skiing down snow-covered slopes, coasting furiously on bobsleds, and skating gracefully across the ice. Therefore, the authors capitalized on their children's natural curiosity about the world around them by exploring the concept of motion in a…

Understanding the scientific method fosters the development of critical thinking and logical analysis of information. Additionally, proposing and testing a hypothesis is applicable not only to science, but also to ordinary facts of daily life. Knowing the way science is done and how its results are published is useful for all citizens and…

Three sample physics problems are presented in this article. The solutions to the three problems addresses a major student difficulty in problem solving--knowing where to begin. The first suggested step is to begin by stating what is asked for. Step 2 is identifying the fundamental physics that underlies the problem situation. Step 3 is isolating…

Methods used to investigate problems in the sciences include building-up strategies, insight, and change (or serendipitous discovery). Discusses appropriate learning experiences for the undergraduate science students so they are more likely to benefit from the second method of scientific discovery as they make a career in their chosen field.

Demonstrates what theoretical physicists make a rule using juggling. Provides the thinking process and calculating procedure. (YP)

A discussion is provided of an instructional technique which has been used in a lower-division biology course to identify and clearly define critical thinking skills for students, model the skills, and give students frequent feedback by describing and evaluating what they are doing. Section I considers the links between the critical thinking and…

The Information Age has been shaping the conception of thinking in education through the capability of computerized problem solving, through the resulting application of the information processing model to human thinking, and through the theories emerging from other cognitive science research in metacognition, construction of knowledge, and…

Describes an exercise that uses riddles to expose students to important aspects of the process and experience of scientific thinking. Contends that the exercise allows students to examine their thought processes and to view scientific questions from different perspectives. Reports positive student reaction. (DB)

Problem solving that both requires and develops higher-order thinking skills is illustrated in the EQUATIONS Challenge Matches program, which consists of computer diskettes at the elementary, intermediate, and advanced levels plus a multi-level diskette. Samples of computer output are given, with the results of various types of experimentation…

The National Aeronautics and Space Administration (NASA) has produced a distance learning series of four 60-minute video programs with an accompanying Web site and companion teacher guide. This teacher guide accompanies the first video in the series. The story line of each program involves six ethnically diverse, inquisitive schoolchildren who…

This teacher guide accompanies the second video in the series. The story line of each program involves six ethnically diverse, inquisitive schoolchildren who…

Uses a problem-solving task to compare the performance of school students, university students, and research scientists on a laboratory-based science investigation. Reports limitations in the work of the school students and provides insights into the development and nature of expertise in investigation skills. Presents recommendations for…
