Computers represent the digital phase of the Industrial Revolution, contribute to centralizing corporate and political power, worsen the growing environmental crisis, and displace local knowledge with data. By framing discussions of computers in terms of these worldwide trends, readers can avoid the simplistic thinking surrounding discussions of…

A videotape series produced by the Annenberg/CPB Math and Science Collection demonstrates college and secondary students' misconceptions about everyday phenomena and advocates teaching for understanding. Third International Science and Mathematic Study data show American and German teachers' interest in procedures and algorithms, compared with…

Summarizes the results of a survey that revealed several dichotomies between what instructors felt introductory psychology courses delivered and what students wanted. Students desired a knowledge of people and relationships while the instructors felt the courses provided a broad overview of the discipline. Includes statistical data and analysis.…

Maintains that recent criticism of cognitive psychologists' conception of irrational emotions as marginal and ephemeral is misguided and inaccurate. Argues that this interpretation is a misstatement of the psychologists' position and analyzes the process resulting in this misinterpretation. Discusses the implications of these arguments for moral…

Investigates the procedural understanding of first-year university science students in South Africa. Explores ideas related to the reliability of experimental data and discusses the types of reasoning underlying the responses. (DDR)

According to William Spady's "Beyond Counterfeit Reforms," politically driven, mechanistic "reforms" box educators into smaller, limiting ways of thinking and running schools. Donald McAdams's book "Fighting to Save Our Urban Schools...and Winning!" shows the salubrious effects of high expectations and community…

Across the nation, districts are throwing beginning administrators into school leadership positions, mistakenly assuming they already know everything. Training programs are preparing principals for a long-obsolete work environment. Committed mentors and on-call coaches can help overwhelmed and overworked principals become effective leaders. (MLH)

Describes remedial instruction activities as well as activity developmental strategies that utilize the results obtained from previous research on students' misconceptions related to photosynthesis to enhance 11th- and 12th-grade biology students' understanding of photosynthesis. (ZWH)

Identifies and quantifies the chemistry conceptions used by students when solving chemical equilibrium problems requiring application of LeChatelier's Principle, and explores the feasibility of designing a paper and pencil test to accomplish these purposes. Eleven prevalent incorrect student conceptions about chemical equilibrium were identified…

Describes a concrete teaching model designed to eliminate students' misconceptions about current flow in electrochemistry. The model uses a semi-permeable membrane rather than a salt bridge to complete the circuit and demonstrate the maintenance of cell neutrality. Concludes that use of the model led to improvement in students' understanding at…

Earth science teachers know how frustrating it can be to spend hundreds of dollars on three-dimensional (3-D) models of Earth's geologic features, to use the models for only a few class periods. To avoid emptying an already limited science budget, the author states that teachers can use a simple alternative to the expensive 3-D models--sand. She…

To soothe faculty distrust and encourage engagement, or reengagement, in exploring applications of digital technology for teaching, the authors believe it is necessary to do three things: (1) create incentives for faculty that balance public service goals with professional and entrepreneurial rewards; (2) clarify ownership and usage rights of…

Diffusion and osmosis are central concepts in biology, both at the cellular and organ levels. They are presented several times throughout most introductory biology textbooks (e.g., Freeman, 2002), yet both processes are often difficult for students to understand (Odom, 1995; Zuckerman, 1994; Sanger "et al.", 2001; and results herein). Students…

Just-in-Time Teaching (JiTT) combines the best features of traditional in-class instruction with the communication potential available via the Web. We describe here how JiTT has been used in Biology Education and how it can be used in Food Science Education. JiTT uses Web-based "Warm Up" assignments due before class to stimulate critical thinking…

The candle burning experiment is usually conducted in lower secondary classes to prove the (about) 20% oxygen in air. The aim of this paper is to show that teachers misinterpret the results of the experiment to satisfy the objectives of teaching this experiment. However, when the results of this experiment are interpreted correctly, the objectives…
