Experimental research on perception and cognition has shown that inherent and manipulated visual features of mathematics problems impact individuals' problem-solving behavior and performance. In a recent study, we manipulated the spacing between symbols in arithmetic expressions to examine its effect on 174 undergraduate students' arithmetic…

The hammer-and-nail phenomenon highlights human tendency to approach a problem using a tool with which one is familiar instead of analyzing the problem. Pedagogical suggestions are offered to help students minimize their mathematical impulsivity, cultivate an analytic disposition, and develop conceptual understanding.

The purpose of this study was to investigate the influence of cognitive training (CT) using mobile applications on attentional control and impulsivity among pre-service teachers. Pre-service teachers were divided into two groups: experimental (n=25) and control (n=14) groups, they were selected from a large sample (n=718). Over 28 sessions, the…

One of the essential problems, in educational data mining, is to predict students' performance on future learning materials, such as problems, assignments, and quizzes. Pioneer algorithms for predicting student performance mostly rely on two sources of information: students' past performance, and learning materials' domain knowledge model. The…

Introduction: Scientific and technological areas include tuition based on highly visuo-spatial specialization and problem solving. Spatial skills and problem solving are embedded in a curriculum that promotes understanding of Science and technical subjects. These abilities are related to the development of executive functions (EFs). We aim to…

Factors distinguishing adolescents who experienced a precipitating event in the week preceding a suicidal crisis from those who did not were examined. Among 130 suicidal inpatients (mean age = 15.01 years), those who experienced a precipitating event reported significantly lower depressive symptom scores, better perceived problem solving, less…

We present a quantitative model for predicting the level of difficulty subjects will experience with specific problems. The model explicitly accounts for the number of subproblems a problem can be broken into and the difficultly of each subproblem. Although the model builds on previously published models, it is uniquely suited for blending with…

From a theoretical viewpoint, educational interfaces that facilitate communicative actions involving representations central to a domain can maximize students' effort associated with constructing new schemas. In addition, interfaces that minimize working memory demands due to the interface per se, for example by mimicking existing non-digital work…

Background: A growing interest exists in mechanisms involved in behaviour problems in children with mild intellectual disabilities and borderline intelligence (MID/BI). Social problem solving difficulties have been found to be an explanatory mechanism for aggressive behaviour in these children. However, recently a discrepancy was found between…

Education deans in the United States describe their approach to solving leadership problems that were cast as organizational dilemmas. The deans who participated in the study had been education deans for at least 6 to 7 years, indicating that they had avoided the revolving door syndrome of 4.5 years in a single appointment. Deans described their…

The maturation of the adolescent brain is focused on two tasks: developing autonomy and understanding self in context of the community. Therefore, parents and other adults must assure that young people have multiple opportunities to interact in supportive environments where they can develop the capacity to self-regulate and achieve autonomy.…

Problem solving and student-centred learning have received a great deal of attention in mathematics curricula for schools and in some universities. Much of this emphasis developed from the pioneering work of George Polya in heuristics, problem solving, and mathematics education. In this study, the author reviews Polya's work, and some of its later…

This article describes how providing effective and timely feedback gives new life to student assessment. Such feedback enables students to become better problem solvers and assessors of their own work. Providing effective and informative feedback is a large part of the assessment process: a means not an end that exists to improve learning and…

Both between- and within-group differences in children ages nine to eleven identified as having reflective or impulsive cognitive tempos. Cognitive tempo was first assessed using Kagan's Matching Familiar Figures test, and children were later tested on the Raven's Standard Progressive Matrices. (Author/RH)

To examine the relationship between response accuracy and tempo, as measured by the Matching Familiar Figures Test (MFF) and criterion measures, 233 7-, 9-, and 11-year-olds were given the MFF, two problem-solving tasks, and a test of academic achievement. (Author/JH)
