Presents a problem-solving activity in which students first guess and then check their answer. Also presents an activity to help students develop skill in understanding the question in a problem and a suggestion to help develop a classroom climate conducive to problem-solving. (JN)

Teachers often have difficulty responding to emotionally upset children in ways that help the students solve their problems. Examples of commonly used "put-downs and put-offs" and suggested techniques that teachers can use to lend emotional support are offered. (DF)

Discusses the nature of and the steps involved in a mathematical investigation, suggesting that a mathematical investigation can be used as a tool for developing mathematical processes in learners. Several examples of investigations suitable for secondary levels are included. (JN)

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…

Discusses: (1) the architecture of expert systems; (2) features that distinguish expert systems from conventional programs; (3) conditions necessary to select a particular application for the development of successful expert systems; (4) issues to be resolved when building expert systems; and (5) limitations. Examples of selected expert systems…

Presents a method for solving problems related to gas laws, the mole concept, molarity, heats of reactions, and other chemical concepts. Also presents another method which was devised to simplify the teaching of stoichiometric calculations using conversion factors. (JN)

An interdisciplinary unit on investigation guides gifted students up to age 14 through problem solving activities in language arts, mathematics, science, and social sciences. (CL)

Overview of the artificial intelligence (AI) field provides a definition; discusses past research and areas of future research; describes the design, functions, and capabilities of expert systems and the "Turing Test" for machine intelligence; and lists additional sources for information on artificial intelligence. Languages of AI are…

The visuo-spatial centers of the right brain are crucial to being able to problem solve or conceptualize (two abilities necessary for success in understanding science). Yet, current educational format is almost exclusively a left-brain undertaking. Reasons why educators should emphasize right-brain understanding in educational curricula at all…

Describes an experiment (using plastic bags) designed to give students practical understanding on using statistics to evaluate data and how statistical treatment of experimental results can enhance their value in solving scientific problems. Students also gain insight into the orientation and structure of polymers by examining the plastic bags.…

Addresses issues related to the use of microcomputers for solving problems. Includes considerations of the impact of software availability, the nature of software for chemical education, general-purpose software, and dedicated software. (JN)

Proposes use of quality circles (QCs)--groups of employees who meet to learn and apply techniques for solving problems affecting work or workplace--to involve library employees in decision-making process and improve morale and product/service quality. Basic philosophy, establishment of QC, and QC techniques are noted. Twelve references are…

High performance liquid chromatography (HPLC) is used to separate and quantitate beta-carotene, chlorophyll a, and chlorophyll b originating from collard greens. Experimental procedures used and typical results obtained are discussed. (JN)

The article proposes a model for developing leadership among gifted students. Four components of the model are identified and sample subskills described: cognition (exploration, research); problem solving (incubation, creative thinking); interpersonal communication (self realization, cooperation, conflict resolution); and decision making skills…

Describes the Whimbey-Lochhead approach to help students develop problem-solving skills, providing instructions for using the approach in instructional programs. Includes a list of 70 tactics or heuristics used (or misused) in problem solving. Other ideas and information from books and articles on problem solving are included. (JN)
