A problem-solving test completed by 49 preservice agricultural educators showed a lack of competence in mathematical problem solving. Those who scored higher were more likely to have completed advanced mathematics courses and had higher ACT math scores. (JOW)

This study examined the use of online argumentation scaffolds to engage and support coherent argumentation. Participants were students in an undergraduate economics course. Results showed that providing a constraint-based argumentation scaffold during group problem-solving activities increased the generation of coherent arguments and resulted in…

Use of the calculator to create a series of iterations to approximate i to some desired degree of accuracy is illustrated with three problems on interest rates. (MNS)

Describes investigation of effectiveness of computer-presented organizational/memory aids (matrix and verbal charts controlled by computer or learner) as instructional technique for solving Pico-Fomi problems, and the acquisition of deductive inference rules when such aids are present. Results indicate chart use control should be adapted to…

Describes a study which analyzed problem solvers' error detection processes by instructing subjects to think aloud when solving statistical problems. Effects of evaluative episodes on error detection, detection of different error types, error detection processes per se, and relationship of error detection behavior to problem-solving proficiency…

Describes a study conducted at the University of Southern Queensland (Australia) that investigated problem-solving behavior in statistics by documenting differences between successful and unsuccessful students. Two methodological approaches are described: one required students to identify key structural features of common problems, and the second…

Introduces a method for gathering process information related to computer simulations and examines changes in learners' responses as a means of understanding the kind of learning that occurs within the simulations. Data gathered from 87 undergraduate education majors using simulations that teach the application of behavior analysis procedures for…

This study was designed to investigate the effects of the presence or absence of metacognitive skill tools available in hyperspace environments on field independent and field dependent learners. Learners were engaged in problem solving in an information-rich hyperspace based on a lesson on the attack on Pearl Harbor. Forty undergraduates were…

To study how the organization of information affects the way that information is interpreted, a total of 404 undergraduates in two studies (151 and 253 students, respectively) solved statistical reasoning problems based on data presented in a variety of types of graphs and tables. When assessing relative probabilities, students were equally…

Undergraduates in a computer literacy class were pretested on analogical reasoning skills. One section then received LOGO programing instruction, and the other section received nonprograming instruction on computer uses in education. Posttest results indicated that analogical reasoning skills development is a consequence of LOGO programing and…

Describes a course designed to teach the relationship between science, agronomy, and society. Includes course and class description, course content, and evaluation of the course. (11 references) (MCO)

Pretests measuring critical thinking ability and mental alertness were administered to 72 first-year college students at the beginning of an introductory computer programing course. Posttests administered at the end of the semester showed significant improvement in both areas, indicating that instruction in programing improves students' critical…

Describes a study that was conducted to determine whether learning to program a computer in Pascal or FORTRAN improved problem-solving skills of college students when compared to a control group and to determine which programing language was more effective in the development of problem-solving abilities. (26 references) (LRW)

Describes decision-aiding software, Policy/Goal Percentaging (P/G%), that can process a set of controversial alternatives when used with microcomputer-aided instruction. The benefits and objectives of microcomputer use are discussed, and applications of the software to problems in the fields of natural sciences, social sciences, and the humanities…

This study sought to describe graduate students' opinions of selected learning activities encountered in large-group, teacher-led instructional contexts. The subjects, 40 graduate students of instructional technology at a major western university, completed a questionnaire. The instrument asked subjects to rate each of ten alternative learning…
