This study focuses on the effectiveness of "Solutions Unlimited," a computer software program developed to teach problem solving to middle level students. Fifty-one fourth, fifth, and sixth graders (21 girls and 30 boys) attending a private school in a small mid-west community were the subjects for this experiment; none had received…

Error analysis performed on data sets revealed that seventh grade students used a variety of rules of operation for solving the signed-number arithmetic problems. The data sets were obtained from an experimental study in which students were randomly assigned to study either of two lessons written on a computer based education system. The two…

This report describes the Generalized Maintenance Trainer-Simulator (GMTS), an instructional system designed to give electronics students intensive troubleshooting practice in a simulated hands-on training environment, and reports on a field evaluation of the GMTS applied to systems level troubleshooting in radio communications. The GMTS can be…

This report describes the planning, implementation, and outcomes of the first phase of a project to create and implement computer-based materials for a problem-oriented curriculum in a training program for physician assistants. It examines the underlying causes of the project's failure to achieve the Phase I objectives, and documents them as…

Computer coaching of students as an aid in problem-solving instruction is discussed. This report describes an advanced form of computer-assisted instruction that must not only present the material to be taught, but also analyze the student's responses. The program must decide whether to intervene and how much to say to a pupil based on its…

One aspect of tutoring skill for technical subjects is individualized, adaptive sequencing of the problems given to students as learning exercises. A Curriculum Information Network (CIN) describes the relationships between the problems in a CAI curriculum and the concepts and skills that they are intended to teach. It is a basis for selecting…

This study investigated the problem-solving performance of education undergraduates while engaged in the solution of complex, data-rich, real problems in a computer environment. The problem used was the riddle of the frozen wooly mammoths. Two instructional programs were used: the problem mode (I) engages the problem-solver in the data base with…

A Word Problem Program was set up to teach elementary school students how to solve arithmetic word problems and to teach some problem solving skills applicable to nonword problems. All instruction is accomplished through a computer program. Goals of the program are described along with three basic instructional decisions and the reasons for them,…

The hypothesis that memory support (MS) reduces state anxiety (A-State) and errors in a computer assisted learning task was investigated. It was predicted that high A-State students given MS would make fewer errors than high A-State students given no memory support (NMS). Low A-State students were expected to perform equally as well with or…

Frame-oriented computer-assisted instruction (CAI) systems dominate the field, but these mechanized programed texts utilize the computational power of the computer to a minimal degree and are difficult to modify. Newer, generative CAI systems which are supplied with a knowledge of subject matter can generate their own problems and solutions, can…

The appropriate and effective uses of the computer in an individualized school were examined in this project. The project investigated the uses of computers for instructional assistance, including testing, management, tutorial instruction, drill and practice, exploration and discovery, and problem solving; the design of a small computer…

LOGO is a programming language developed at Bolt, Beranek and Newman, Inc., specifically for use in teaching. It provides the student with a set of numerical and symbolic primitives as elements for gradually building extended, complex program structures. The building of these structures is facilitated by a procedure-oriented programming heuristic…

Tree searching was applied as a computer model of simple addition sentences. Results indicated that the number of problem reductions performed in tree searching accounted for most of the variance across problems in student error rate and solution time. The technique constitutes a computer test for the adequacy of a problem solving prescription.…

The author outlines where we've been and where we ought to be going with computer-enhanced mathematics especially with respect to student motivation and problem solving. (MN)

Discusses a study which focused on students' actual programming behavior. Descriptive data revealed that the high school students spent little time in planning their programs or writing their code. Their debugging behavior was characterized as a trial and error strategy. (ML)
