A series of interviews and classroom observations were conducted with a group of in-service science teachers, students, school principal, and computer lab supervisors, from a "Discovery" female school in Jordan to assess their utilization of information and communication technology (ICT) in teaching science. The study also intended to…

This paper attempts to discover and describe the salient common factors constituting four high school science teachers' role conceptions. In a year-long ethnographic study, two researchers worked as participant observers in various science classroom settings at an urban high school. Teachers in charge of these classrooms were interviewed on issues…

Examined student behaviors during laboratory activities and the amount of time involved in each behavior. Approximately 89 percent of the student time was spent interacting with others. The amount of time spent on various activities appeared to be dependent on the nature of the activity and on the make up of the laboratory group. (YP)

Discusses instructional strategies that help students make and differentiate between observations and inferences, including the use of analysis, synthesis, and evaluation processes. Suggests that early activities focus on analytical procedures in such a way that they can be explained in terms of facts and principles that students will readily…

Discusses a game and related activities to help students develop observation and inference skills. (MKR)

Discusses the use and significance of geologic generalizations. Provides examples of different types of geologic observations and describes how they relate to the way explanations are formulated. Proposes that the mentioned generalizations be regarded as "laws." (ML)

Describes activities for helping children develop skills in quantitative observations. (PR)

Proposes that teachers possess some awareness of the history and philosophy of science and epistemological understanding of the nature of the subject area. Offers perspectives on the role of observation; on hypotheses, theories, and laws; and on models in biological education. (ML)

Presents a classification scheme for identifying sedimentary rocks in introductory geology laboratories. The key consists of an ordered sequence of tests to perform and observations to make which then suggests a rock name or directs the student to additional tests and/or observations. (ML)

Presents activities designed to allow students with backgrounds in states of matter and measurement to have a very concrete hands-on, minds-on experience with both physical and chemical changes and to compare and contrast the end products of each type of change in a concrete way. (PR)

Discussed is the preparation of a lesson plan. The lesson objectives, prerequisite concepts, materials and preparation, lesson, and quizzes are described. The evaluation criteria of the lesson plan is suggested. Provided is an example of lesson plan on guard cells. (YP)

Explores opportunities for enriching science instruction outside school building. Discusses various nature trails for sensory awareness, observation, problem-solving, and nature identification. Explores possibilities for science study using school yards, parks, community sites, museums, nature centers, and libraries. Briefly examines television…

Reported are observational limits of detectability for several single stimulus and multi-stimuli observation tasks in secondary level chemistry. Provided are tables of actual results obtained including type of observation, chemical system used, method of determining stimulus magnitude, and observational thresholds. (Author/YP)

Many aspects of string theory are abstract and difficult for even theoretical physicist to fully comprehend. The activities in this guide are designed to help teachers and students better understand some of the basic concepts underlying particle physics and string theory. A list of additional resources and a glossary are also included. Each…

Presents several electricity activities for developing student's science process skills of observation and inference. (PR)
