Newton's second law is one of the cornerstones of the introductory physics curriculum, but it can still trouble a large number of students well after its introduction, hobbling their ability to apply the concept to problem solving and to related concepts, such as momentum, circular motion, and orbits. While there are several possibilities for…

In this paper we describe student use of a series of connected online problem-solving activities to remediate atmospheric carbon budget misconceptions held by undergraduate university students. In particular, activities were designed to address a common misconception about conservation of mass when students assume a simplistic, direct relationship…

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…

The aim of this study was to investigate effectiveness of PDEODE (Predict-Discuss-Explain-Observe-Discuss-Explain) teaching strategy in helping students make sense of everyday situations. For this, condensation concept was chosen among many science concepts since it is related to many everyday-life events. Forty-eight eleventh graders students…

Discusses strategies for overcoming common student misconceptions. Strategies include using pretests followed by teaching techniques planned to contrast new information with students' previous ideas; using pretests followed by time for students to question ideas and test their knowledge; and giving students a real-world task that can only be…

Integrates story telling into a science activity on the density of liquids in order to increase student interest. Shows the relationship between mass and volume ratio and how they determine density. Includes teacher notes. (YDS)

Presents hands-on activities to teach about the causes and consequences of strokes. (YDS)

Presents strategies for encouraging dialog with students from eliciting preconceptions to bringing closure to a unit. Includes the general structure of an instructional unit that employs dialog, strategies for teachers to use, and strategies for students which include active listening. (DDR)

Discusses the scheme and findings of a study designed to identify the conceptual knowledge used by high school students to solve a significant problem related to osmosis. Useful tips are provided to teachers to aid students in developing constructs that maximize understanding. (ZWH)

Provided is a perspective on the teaching of a unit on the Earth in space. The themes to be found within the unit, approaches and resources that can be used for teaching and learning the subject, and some of the typical ideas that children hold about astronomical subjects are provided. (KR)

This paper describes how the learning cycle leads students to become more skilled reasoners. The three phases of the learning cycle are described and examples and goals of each are provided. Information is also offered on the three types of learning cycles: the descriptive; the empirical-inductive; and the hypothetical-deductive. Each is described…

Designed to address the major conceptual problems associated with respiration and photosynthesis, this module can be used with high school students or college nonscience majors including those in elementary education. It is one in a series developed by the project Overcoming Critical Barriers to Learning in Nonmajors' Science Courses. The…

Describes a Russian approach of using literature to make physics instruction more interesting and attractive to students. (PR)

Designed to address the major conceptual problems associated with evolution and variation and survival in populations, this module can be used with high school students or college nonscience majors including those in elementary education. It is one in a series developed by the project "Overcoming Critical Barriers to Learning in Nonmajors'…

The teacher's role in directing science activities is examined in this book. Suggestions are offered on what teachers might do with the activities and advice is given on how the activities could be used. Each of the eight chapters contains a brief summary at the beginning, a detailed review at its close, and a list of specific guidelines for…
