Two classes of second graders (24 high and 19 average math ability students) were taught to use differing schematic drawings to represent differing categories of addition and subtraction word problems. Results indicate that American textbooks could include many more difficult word problems than is currently the case. (TJH)

Computer studies courses should incorporate as many computer concepts and programming language experiences as possible. A gradual increase in problem difficulty will help the student to understand various computer concepts, and the programming language's syntax and structure. A sidebar provides two examples of how to establish a learning…

This paper analyses new methods of teaching skiing in terms of a computational paradigm for learning called increasingly complex microworlds (ICM). Examining the factors that underlie the dramatic enhancement of the learning of skiing led to the focus on the processes of simplification, debugging, and coaching. These three processes are studied in…

This study of individual differences in performance of a geometric analogies task included four-alternative test items and studied eye movements and confidence judgments as well as latency and error. Results were interpreted using two hypothesized performance strategies: constructive matching and response elimination. (Author/BW)

The operating characteristics of 114 mathematics pretest items from the Praxis I: Computer Based Test were analyzed in terms of item attributes and test developers' judgments of item difficulty. Item operating characteristics were defined as the difficulty, discrimination, and asymptote parameters of a three parameter logistic item response theory…

Difficulties encountered by students when solving problems were examined using Program of Actions and Methods (PAM) for systematic problem solving in science. Difficulties encountered included those in analyzing the problem, planning the problem-solving process, executing routine operations, and those related to the ways teachers solve problems.…

Performance and persistence on the Concealed Figures Test and the Embedded Figures Test decreased: (1) after short-duration failure when subjects were falsely led to attribute failure to task difficulty; and (2) after long-duration failure when subjects were falsely led to attribute failure to lack of ability. (CP)

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…

A University of Hawaii study compared objective and subjective assessments of the three-step triple jump examination which tests medical students' clinical problem-solving processes. Subjects were 58 first-year students. Results found the subjective assessments were more consistent across problems of varying difficulty level than were objective…

This paper proposes a methodology to calculate both the difficulty of the basic problems and the difficulty of solving a problem. The method to calculate the difficulty of problem is according to the process of constructing a problem, including Concept Selection, Unknown Designation, and Proposition Construction. Some necessary measures observed…

The purpose of this study was to explore the use of a cognitive computer tool by undergraduate calculus students as they worked cooperatively on mathematical tasks. Specific attention was given to levels of cognitive demand in which the students were engaged as they completed in-class labs with the assistance of MathCAD. Participants were assigned…

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…

A series of three experiments was conducted for the purposes of (1) clarifying problems of previous research on the relationship between working memory capacity and performance on figural analogy tasks, and (2) exploring developmental issues concerning executive strategies, working memory capacity, and perceptual processing. Directly manipulating…

Even though several national testing firms have developed measures to evaluate the effectiveness of baccalaureate education, there continues to be a general reluctance on the part of faculty in colleges and universities to accept these measures as criteria on which to evaluate educational programs. Some of the resistance appears to lie in the lack…

TRAINING TASKS WERE PRESENTED UNDER LABORATORY CONDITIONS TO NEWLY INDUCTED ARMY BASIC TRAINEES GROUPED BY ARMED FORCES QUALIFICATION TEST (AFQT) SCORES. THE HIGH GROUP (N=52) RANGED IN SCORE FROM 90 TO 99, THE MIDDLE GROUP (N=30) FROM 45 TO 55, AND THE LOW GROUP (N=61) FROM 10 TO 21. TASKS WERE VARIED IN COMPLEXITY INCLUDING SIMPLE AND CHOICE S-R…
