Infants' home-based Q-sort scores of security, dependency, and sociability were compared to laboratory Strange Situation classifications of secure, anxious-resistant, and anxious-avoidant. Secure classification was associated with Q-sort security and sociability, but not dependency. (BC)

The assumptions common to all capture-recapture models for estimating population size are reviewed. A simulation using either a playing board, counters, and dice or computers is described. Classroom implications of using the board game are discussed. (KR)

Compares past methods of teaching languages with the current emphasis on teaching oral/aural skills. The use of technology is then discussed, in particular the language laboratory, the videotape recorder, the videodisk, and the computer. Suggestions are offered on how to adapt each for educational purposes. (23 references) (CFM)

Discussion of science and math instruction for elementary and secondary students highlights the use of microcomputer-based laboratories (MBL). Data collection, storage, and display are discussed, the use of databases to organize and manage information is described, and the exchange of ideas with other students through telecommunications is…

The professional development school (PDS) has its roots in efforts to professionalize the teaching profession and in the concept that schools of education must reshape themselves as professional schools. This article outlines the concepts which have spawned and guided PDS implementation and discusses the realities faced by PDS planners and…

Presents the following guidelines to consider before, during, and after hands-on inquiry: (1) plan and prepare; (2) create problem intrigue; (3) give students the responsibility of solving the problem; (4) offer feedback and guidance; (5) debrief; and (6) anticipate, prevent, monitor, and adapt. (PR)

Provides instructions for making telescopes. The design and instruction sheets given to students are provided. (PR)

Clarifies the issues of animal rights as they effect animal use in research and education through an examination of the current use of animals, a historical look at animal use, and a consideration of the philosophical underpinnings of the animal rights and pro-use viewpoints. (PR)

Describes activities using sensors connected to a computer via a data-logger. Elementary students investigated several scientific questions of sound, light, and temperature sensors including: What is the effect of putting a coat on a snowman? How can you make a hot drink cool down quickly? Do sound, light, and temperature vary in different…

Describes a science program called "Environmental Science on the Three Rivers" which coordinates hands-on water-ecology experiments for local schools on a modified Navy training vessel. The vessel holds 35 students and stops at three major sampling stations during a four-and-a-half-hour class. The program is conducted by people with…

Discusses possibilities for improving undergraduate-level general-education biology courses, particularly through the development of interesting and focused laboratory presentations. Advocates problem-based learning and improving the communication skills of laboratory teaching assistants. (Author/WRM)

Describes some aspects of practical work in science education which can be supported by information and communications technology (ICT). Presents issues to consider when planning ICT-based practical work. (WRM)

This article describes the Kent State University Ameritech Electronic University School Classroom, opened in 1998 to provide a technology-based classroom for K-12 students and a research laboratory for college faculty and students. Other centers studying the impact of technology on teaching and learning are also described. (Contains three…

Describes some of the problems students encounter when they refuse to dissect animals in the classroom, most notably ridicule from other students and even the teacher. Offers suggestions for dealing with ridicule such as humor and education of the offenders. Notes the potential for increased self-esteem and confidence that can be gained by dealing…

Describes two science activities concerning water density and shares an idea for combining these activities into a third, completely new activity. Demonstrates the joy of rekindling the spirit of scientific thinking in a typical classroom. (PVD)
