Discusses the human brain's specialized perception/expression and information processing systems as they relate to student learning. For high school students in the formal reasoning stage, it is suggested that teachers provide instruction based on mental exercises to develop problem-solving insight. (DH)

A comparative study of textbook terms was conducted to determine what high school science skills are necessary for success in associate degree physical science courses. Results indicate that, although enrollment in technology-training programs is increasing, high school textbook treatment of terms remains inadequate preparation for junior college…

The ratio factors approach involves recognizing a given fraction, then multiplying so that units cancel. This approach, which is grounded in concrete operational thinking patterns, provides a standard for science ratio and proportion problems. Examples are included for unit conversions, mole problems, molarity, speed/density problems, and…

Described are techniques and activities that seven different teachers are using in their chemistry programs. These programs were selected as winners of the 1983-84 Search for Excellence in Science Education. (DH)

The preformatted programs of authoring systems are much easier for teacher use in writing computer assisted instruction for the classroom. Advantages, disadvantages, applications, prices, and publishers are provided for six systems (Blocks, CAIware, Eureka, Mentor Master, PILOT, and ZES). (DH)

The National Diffusion Network (NDN) is a federal program that disseminates information about exemplary educational programs and helps other schools replicate them. Each state has an NDN facilitator who can help interested teachers develop and/or find appropriate curricula. Information on applying to and participating in the NDN is given. (DH)

Advocates taking students on field trips to highway roadcuts to illustrate various geological principles. Photographs of three roadcuts (with sample objectives and questions/answers for students to answer) are included. Also included are suggestions for preparation, safety, and activities during such field trips. (DH)

Addresses whether or not science laboratory activities should become a thing of the past. Discusses the impact of the curriculum reforms of the 1960s and 1970s, physical restraints which cause teacher overload, rationale, and objectives of laboratory work. (RT)

Discusses the causes and effects of conceptual errors inadvertently introduced and nurtured by scientists, teachers, and textbook writers. Cites ways to prevent the communication breakdowns that prevent the learning of science. (RT)

Discusses who has the right to determine the use of animals in scientific research which includes medical experimentation and the toxicity testing of compounds, ranging from pesticides to cosmetics. Provides a list of questions for consideration and discussion. (RT)

Explained is a representation of the three categories of spectra. Discusses what a lesson on spectra should include, background information, and equipment needed. Provided is a diagram of an absorption box. (RT)

Explained is an interdisciplinary assignment in which students use scientific knowledge and apply it in a practical situation. Provided is background information and precautions regarding safety procedures. (RT)

Provides information for the development of a lesson which teaches students about sand, discusses facts about sands, sand studies, life in the sands, and sand activities. Includes diagrams showing the range in sand grain shape, formation of sand ripples, and sand samples from around the world. (RT)

Discusses multiple-choice test questions, their advantages, important features, well and poorly written items, and the need to assess students' ability to use higher levels of learning. Cites two ways to include higher level learning skills into the science curriculum and eight rules to consider when constructing multiple-choice tests. (RT)

Explains an activity which can be used to compare the effect of temperature on the rate of chemical reactions to the metabolic reactions that take place within the body. Outlines directions and materials needed to perform the experiment. Lists a number of the body's defenses against extremely low temperatures. (RT)
