Describes a mathematical investigation centered on collecting and analyzing data in a scientific setting. The first experiment teaches the basics of data collection--students should be able to identify variables that might have affected experimental results. The second activity includes designing an experiment to control for these variables. The…

Describes a problem-based unit in which students are charged with the responsibility of discovering what killed the menhaden fish in a local river. Involves the teacher coaching students through the problem and directing them toward resources and lines of inquiry. Enables students to gain an understanding of their local environment and the…

Presented are several simple kinetic systems together with the spreadsheets used to solve them. A set of exercises in chemical kinetics appropriate for an introductory course in physical chemistry is given. Error propagation calculations with experimental data are illustrated. (CW)

Describes interdisciplinary activities with real-world applications ranging from science to mathematics to technology. Cites the study and construction of model bridges as a way for students to learn about engineering concepts and some of their relationships. States that the exercise enhanced teacher cooperation between the different fields. (RT)

Describes case study that examined the processes and outcomes related to the development of knowledge bases by groups of seventh grade science students in Toronto who were studying classification of living organisms. Expert system shells are discussed, and cognitive and metacognitive skills used in the activity are examined. (23 references)…

Describes activities that can be added to any chemistry curriculum and can offer students an opportunity to gain and practice skills in research, written and verbal communication, and database creation and use while working as a part of a problem-solving team. (JRH)

A case study is presented of a science class for 10 underachieving gifted intermediate grade students. The paper describes how a focus on overcoming underachievement might conflict with the need for active, hands-on science activities. Suggestions are offered for integrating the goals of raising self-concept while developing skills of inquiry and…

Listed with examples are six levels of thinking. The design of lessons to teach higher order thinking is discussed. A sample lesson on spontaneous generation which uses this method is provided. (CW)

The purposes of this paper are (1) to demonstrate that medical microbiology laboratory exercises should be presented with a focus on medical applications, not just traditional microbiology and (2) that exercises devoted to differential diagnostic decision making can be used to enhance the problem solving of students. (PR)

Describes a class activity of conducting a mock trial of a pretend situation of a white-tailed deep population creating problems for a town. Procedures, fact sheets, names, and descriptors of characters are provided. (PR)

Students (n=40) who had experienced cooperative and individualistic concept-mapping experiences performed significantly better in solving three biological problems than did control students (n=20). No significant differences were found between students who mapped concepts cooperatively and those who mapped individually. There were mixed results…

Describes a three-week environmental minicourse in a general chemistry class. The minicourse consisted of two distinct phases, a one-week introduction to environmental chemistry and a two-week project involving a particular environmental problem. (PR)

In the process of designing and field-testing bioinformatics curriculum materials, we have adopted a three-stage, progressive model that emphasizes collaborative scientific inquiry. The elements of the model include: (1) context setting, (2) introduction to concepts, processes, and tools, and (3) development of competent use of technologically…

This case study explored how social interaction during science lessons leads to the development of planning skills in students. An analysis of group discussions was conducted. Questions addressed were: (1) What is the nature of planning discourse during science problem-solving activities with young children?; and (2) How is collaborative planning…

Due to its abstract, theoretical nature, the mole concept has been recognized as one of the most difficult topics to teach and learn within the chemistry curriculum. The purpose of this study was to chronicle the development of high school students' conceptions of the mole following a period of instruction in a chemistry class. This investigation…
