This study examined mathematics and science teachers' perceptions and use of four types of examples, including typical textbook examples (standard worked examples) and erroneous worked examples in the written form as well as mastery modelling examples and peer modelling examples involving the verbalization of the problem-solving process. Data…

Teaching and learning based on web or web-based learning is a concept which integrates information and technology in education. Teachers and instructors have to assist their learners to learn to function in this information environment. However, teacher trainers and instructors have limited experience in the integration of ICT by using web in…

This study was designed to evaluate the effects of a proprietary software program on students' conceptual and visual understanding of dimensional analysis. The participants in the study were high school general chemistry students enrolled in two public schools with different demographics (School A and School B) in the Chattanooga, Tennessee,…

Research has shown that affordances of computers may be exploited in the design of mathematical tasks so as to provide interesting and challenging activities. At the same time, opportunities for learning mathematics may be constrained if the design of the task is not appropriate. A tool which allows teachers, researchers and task designers to…

These two issues of a newsletter address the use of computers in developing complex thinking skills. The first issue, for May 1986, includes articles on: environmental science computer applications; computers and higher order thinking in Mineola, New York; a description of case study research identifying effective uses of computers in developing…

Outlines a problem-solving method for beginning chemistry students that utilizes specific, concrete steps as well as computer-assisted tutorials. The method involves an approach referred to as the Factor-Unit Method coupled with a graphical "road map" which allows students to trace problems from start to finish. (JN)

The main aim of this paper is to demonstrate that new and highly effective computer-based learning tools can be designed by adhering to a simple principle: Good learning tools conform to and support the processes and structures that comprise learning. The paper first discusses the processes involved in learning cognitive skills, then describes…

This research study was conducted to examine particular metacognitive monitoring and regulatory skills in the context of solving science problems in a computer-based learning environment. An effort was also made to extend the work of H. Swanson (1990) using a different measure for metacognition and multiple measures of ability, achievement, and…

Describes an experimental test conducted with high school students to determine the effect of posting explicit goal structures on problem-solving performance in an intelligent tutoring system for calculus. Related rates word problems are discussed, and student performance in terms of speed and accuracy is analyzed. (Contains 29 references.) (LRW)

Describes a project where computer-assisted graphical data analyses were introduced to inner-city high school students with weak math and science backgrounds. Provides examples of performance of students on open-ended problem-solving tasks. (PR)

Considers the use of technology, particularly programmable or graphics calculators and computer software, in the transition years from secondary to higher education. Discusses use of software systems like Mathematica in the extended investigative, problem solving, and modeling Common Assessment Tasks of the Victorian Certificate of Education.…

This paper evaluates the effectiveness of a student controlled computer program for high school mathematics based on instruction principles derived from Schoenfeld's theory of problem solving. The computer program allows students to choose problems and to make use of hints during different episodes of solving problems. Crucial episodes are:…

Results from a study of problem solving in the domain of instructional design are presented. Subjects were eight teacher trainees who were recent graduates of or were enrolled in the Stanford Teacher Education Program at Stanford University (California). Subjects studied a computer-based tutorial--the VST2000--about a fictitious vehicle. The…

When using spreadsheets to explore real-world problems involving periodic change, students can observe what happens at each period, generate a graph, and learn how changing the starting quantity or constants affects results. Spreadsheet lessons for high school students are presented that explore mathematical modeling, linear programming, and…

Focuses on the place of discrete mathematics in the grades 9-12 mathematics curriculum and discusses how the topic of recursion should be taught. Presents several examples of recursion involving LOGO, spreadsheets, sequences, Pascal's triangle, and the Tower of Hanoi to illustrate its teaching. (MDH)
