Misconceptions associated with the origins of force and the effectiveness of a bridging strategy for developing correct conceptual models in mechanics are identified for high school physics teachers in this paper. The situation investigated was whether a table exerts an upward force on a book. Student misconceptions related to this phenomenon as…

In this article, the author discusses how drawing exercise can be an invaluable tool in teaching Biology classes. The author uses drawing exercises and requires students to sketch everything from prepared slides of mitosis and plant anatomy to field sightings of birds and protists. His primary goal in integrating art into science is to hone…

Describes behaviors of the domestic cat in terms of developing students abilities to observe. Discussed are play, territoriality and pecking order, catnip, feral studies, and chasing. (CW)

Problem solving is an ideal learning strategy, especially for topics that are perceived as difficult to teach. As an example, a format is described for a problem-solving session designed to help students understand the pressure-flow hypothesis of phloem transport in plants. Five key facts and their discussion can lead to the conclusion that a…

Developing a constructivist view of scientific inquiry and knowledge is considered to be important to the training of future scientists, as well as to the understanding of scientific information by all citizens. The research reported targets the junior high school grades. Curricular materials that introduce seventh graders to the constructivist…

Describes a teaching exercise used to demonstrate the importance of context in studying the ecology of animals. Uses the game of chess to examine the relationship between information and context and as an analogy with ecology. Discusses procedures, examples of results, and insights gained from this activity. (CW)

The rationale and procedures involved with the instructional strategies of concept mapping and Gowin's Vee Mapping are provided in this paper. Specific directives are outlined for building concept maps and vee maps. Examples of both types of these maps are given and explanations are offered on their form and use. Concepts and activities…

Discusses the commonly held misconceptions on heat and examines potential contributing factors. Defines and provides examples of internal energy and heat. Suggests approaches to the teaching of heat for secondary level students. (ML)

The potential of concept mapping, a learning strategy, coupled with assessments oriented toward problem solving used to facilitate meaningful learning, is examined. How students make and use concept maps in studying and the factors that influence the way they are made and used are discussed. Sample concept maps are included. (KR)

The purpose of this study was to investigate the effects of a laboratory-centered inquiry program on laboratory skills, science process skills, and knowledge/understanding. The inquiry approach used in the Foundational Approaches in Science Teaching (FAST) program and a traditional science textbook approach were compared in terms of the three…

Differentiates between problems, exercises and algorithms. Discusses the role of algorithms in solving problems and exercises in chemistry. Suggests that very real differences exist between solving problems and exercises, and that problem solving steps can be and should be taught in chemistry education. (TW)

Provided is a model to depict how the development of process skills can be systematically achieved and in turn determine the students' achievement in science practicals. Modified laboratory instruction is compared with conventional laboratory instruction. The results of field testing on 164 ninth grade subjects are described. (MVL)

Examines (1) how students evaluate information obtained in the science laboratory; (2) the effects of use of microcomputer-based laboratory; and, (3) the effects of explicit instruction on critical evaluation skills. Discusses results in terms of students' propensity to accept incorrect graphs and in terms of the effect of the enhanced instruction…

Describes an instructional strategy based on the learning cycle for teaching the use of significant figures. Provides explanations of teaching activities for each phase of the learning cycle (exploration, invention, application). Compares this approach to teaching significant figures with the traditional textbook approach. (TW)

Examined is the wide range of statements of attainment in the National Curriculum that start with the phrase "be able to." A categorization of these statements is used to provide signposts for effective teaching and learning. The implications for in-service work and assessment arising from this categorization are considered. (KR)
