In 2 experiments, 280 college students studied animations depicting a mechanical operation with concurrent oral narration of the process, successive animation and narration, animation alone, narration alone, or no instruction (the control group). Results are consistent with a dual coding model of retention and problem solving. (SLD)

Explores 40 urban principals' perceptions concerning obstacles to school effectiveness. Schools as organizational workplaces are plagued by stress, frustration, and alienation. There is a growing gap between school culture and the larger society. Kids who no longer buy into the American dream often fail to meet educator-imposed expectations.…

Reports on a study of the effects of computer-simulated experiments (CSE), problem solving, and conventional approaches on high school students' chemistry achievement, science process skills, and attitudes toward chemistry. Testing indicated CSE and problem solving produced greater achievement in chemistry and science process skills. CSE produced…

Nine articles discuss research on cooperative learning with computers and how student interactions at the computer facilitate learning. Current research on cooperative learning methods and computer-assisted learning; and microcomputer-based group problem solving, social-cognitive behaviors, higher order thinking, interdependence, autonomy,…

Discusses how students generate meanings for mathematical word problems, develops a generative predicational model to account for students' comprehension of word problems, and describes an empirical study of Israeli sixth graders that was designed to test the model. Talk aloud protocols of the students are analyzed, and hypotheses tested are…

This article, which is organized around a single, well-known algorithm for root extraction, presents a way of incorporating dynamical systems into the teaching of mathematics. Included are sample exercises using complex numbers and the computer where students have the opportunity to do some analysis on this algorithm. (KR)

Discussed is the question of teachers' knowledge about mathematical topics. The building of an analytic framework of subject matter knowledge for teaching the topic of functions in mathematics is demonstrated. Discussed is the construction of mathematics courses prospective mathematics teachers take. (KR)

Reported are the effects of a conceptually oriented unit on decimal fractions. The relationships between short-term changes in solving processes and the stability of these processes over time, performance of students, and entry achievement level and the long-term effects of conceptually based instruction are discussed. (KR)

Various ways in which computers can be used in the classroom depending on the subject, students' background, and individual teaching style are discussed. A way to evaluate professional software packages for use in the classroom is included. (KR)

The programing language PROLOG is compared to LOGO in terms of its ability to handle mathematical ideas. This is demonstrated by using PROLOG in solving a geometric theorem and two lemmas. The listings of the computer programs used to solve the problems are included. (KR)

The relationship between computer-aided design (CAD), computer-aided manufacturing (CAM), and computer numerical control (CNC) computer applications is described. Tips for helping educate the CAM buyer on what to look for and what to avoid when searching for the most appropriate instructional CAM package are provided. (KR)

Twelve middle school students, working in pairs, used a computer microworld to explore introductory geometric transformational concepts. Despite a tendency for symbolic overgeneralization, the students were able to use visual feedback from the microworld and discussions with partners to correct their own mistakes. (Author/JJK)

Suggestions for college development officers for improving efficiency in researching potential donors include networking with parents, alumni, faculty, trustees, and even the college president; using class notes, local and national business publications, and computer databases; and using personal organizational ability, imagination, and…

Quilt-making is presented as an activity that helps elementary school children recognize and appreciate geometry in their world while developing their problem-solving skills. Students choose an appropriate pattern and cooperatively make the quilt. Related measurement questions and problems are provided. (MDH)

Presents seven scenes showing everyday classroom situations that give students the options of applying their own problem-solving strategies to solve everyday problems of life and enable them to experience mathematical power coming from self-initiated insights into mathematical concepts. (MDH)
