Introduces the growing body of research on development of scientific reasoning skills, focusing on reasoning and problem-solving strategies used in experimentation and evidence evaluation. Maintains that current research examines strategy development and use in moderately complex domains to examine conditions under which subjects' theories…

This analysis of the relationship between science education and technology over the past 15 years focuses on lessons learned from research on learning and instruction, the relationship between the teacher and technology, and the influence of technological advances on educational practice. Five conclusions are drawn: (1) courseware authoring…

Provides a point of view that the organic lab is a good place for the student to use and learn problem solving skills while performing the cookbook experiments. Notes that an equilibrium between the theoretical and practical aspects of organic chemistry should be established. (MVL)

Argues that the changing informational content of biology, tightening cost constraints, improving electronic media, increasing pressures from advocates of animal rights, and the growing evidence of the effectiveness of electronic modes of instruction are undermining the traditional belief that all students in biology should have the benefit of…

Reviews the work of the Commission on Undergraduate Education in the Biological Sciences (CUEBS) from 1964 to 1972. Suggests that now is the appropriate time to reassess their efforts, to build on their successes, and to use their experience to attack some of the continuing problems facing biology education.

The increasing complexity of evaluating information retrieval (IR) systems is discussed in terms of contributing factors and research methods. Examples are provided from experiments with weighted searching on a front-end system, information-seeking behavior and online catalogs, and the OKAPI experimental retrieval system.

Agriculture and the rural economic bases in mining, fisheries, forestry, and natural resource extraction are experiencing major social and economic changes. The farm and rural crises of the 1980s are not short-term aberrations, but symptoms of long-term trends that were partially hidden by the relatively good times for agriculture and rural areas…

There is some confusion in discriminating basic educational research (which explores the why's and how's of learning) from applied research (which seeks to test the implications of basic research results) because some investigations are conceived without a clear purpose. Thus, it is not uncommon for researchers to suggest implications that…

Proposes that preparative chemistry is an important and integral part of chemistry as a whole, and an excellent way to introduce students to descriptive chemistry. Provides an outline for students to follow for converting and transforming salts. Suggests a set of general guidelines for studying anion and cation transformations. (TW)

This description of microcomputer-based laboratories (MBL) for science focuses on experiments with a motion detector by non-science majors at Tufts University. Exercises had been used previously with sixth grade middle school students, indicting the effectiveness of MBL for students with a wide range of abilities. (Author/LRW)

Describes the rationale for using computer-assisted videodisc lessons to enhance introductory chemistry courses at University of Illinois, and presents sample lessons to illustrate what students see and do as they proceed through the lessons. Lesson construction and use are reviewed. (MBR)

Discusses consequences of using computer-assisted learning (CAL) packages for experiment planning in undergraduate physical chemistry laboratories and examines textbook presentations and syllabus criticism. An approach to syllabus reconstruction that combines operational research with experiences of CAL development program is demonstrated through…

The "two-phase" structure of teacher education programs in the Federal Republic of West Germany has traditionally separated the theoretical from the practical aspects of teacher training. An experimental program developed at the University of Oldenburg in the 1970s appeared to overcome this problem, but was short-lived. (Author/PP)

Offers the opinion that the creative and imaginative dimension of chemistry can be added in chemistry instruction through the acknowledgement of ambiguity in experimentation and science history. (CS)

This article discusses how children can build teamwork through science activities. Through science experiences, the excitement can generate a sense of shared community in class. Science experiments help develop children's learning. Science experiences are a prime source of powerful new words because they use a common language to describe the…
