Describes a constructivist chemistry laboratory approach based on students' personal experiences where students had the opportunity to develop their own experimental processes. Points out both the fruitfulness and difficulties of using a graduate student as a teaching assistant. (YDS)

Criticizes the way organic chemistry teaching laboratory experiments are approached from the viewpoint of physical chemistry. Compares these experiments to cooking. Stresses that what matters is not the practice of the finger skills of organic chemistry but practice in the style of thinking of organic chemists. (CW)

Components of a problem-solving lab include eight activity zones: problem setting, information gathering, problem analysis, modeling, problem evaluation, prototype, observation, and television studio. (SK)

Focuses on rewards in scientific research. Discusses the social structure of science and its ability to inhibit creativity as ilustrated in the work, "The Act of Creation: Creative Processes in Science." This is related to accounts of the discovery of the chemical structure of DNA. (SA)

Describes generic problem-solving model constructed by D. Koberg and J. Bagnall that can be used by writing center tutors and that progresses as follows: (1) accept situation, (2) analyze, (3) define, (4) ideate, (5) select, (6) implement, (7) evaluate. Provides tutors with coherent framework and with way of breaking larger framework down into…

Discusses the use of simulations in education and suggests ways in which they can be made more cost effective. Highlights include electronic performance support systems; smart tools; examples of the use of simulations in an electronics laboratory and for interpersonal problem-solving skills; and computer-aided instructional design. (Contains 11…

Definitions for the terms open-ended, problem solving, and investigations are considered. The interaction between these terms and teaching styles are discussed. Student influences over the learning process in this type of investigation are examined. (CW)

Some typical teacher concerns about technology education are explored. Answers reflect the belief that implementing technology education does not require entirely new instruction methods. Concerns explored include (1) use of the project method, (2) specialized equipment, (3) problem-solving, (4) needs of special students, and (5) teacher skills.…

A trend at U.S. colleges and universities in teaching first-year science courses is discussed. An approach in the classroom and lab in which students engage in science through observation and hypothesis is emphasized. Hands-on science, experiential science, and constructing science through cooperative learning are discussed. (KR)

Reports the results of a study that examined the patterns of interactions of high school student partners engaged in problem-solving activities while working through computer simulation activities in an astronomy lab. Observations, interviews with teachers and students, and a software program evaluation are discussed. (LRW)

Argues that educational computing is a discipline and discusses issues that need to be addressed in this discipline, including similarities with experimental psychology; networks and integrated learning systems; problem-solving software versus domain-specific software; computer labs versus classroom integration; software quality; computer equity;…

Discusses the advantages of using content specific problem solving as a vehicle for undergraduate instruction in biology, and describes different software tools used to implement this model. The areas discussed include simulated laboratories, the construction of binary classification schemes using computer programs, and scientific writing using…

Describes experiences of a fifth grade teacher who converted her classroom to a whole language teaching and learning environment. In her child-centered classroom, she emphasizes student empowerment and decision making, cooperative learning, and flexibility. Her top priority is for students to participate and learn critical thinking and…

Discusses the inherent flaws in considering and using the epistemology of the natural sciences as equivalent to a pedagogic basis for teaching and learning in the natural sciences. Discusses the difference between practicing science and learning to practice science. Concludes with the presentation of three new motives for the use of laboratory…

Identifies and discusses 10 overly optimistic claims for the use of computers in the classroom, and makes recommendations concerning each claim. Highlights include computer labs versus curriculum integration; the development of hardware versus software; the values of computer literacy; computer networking; computer education training; the use of…
