The Functions of Pictures in Problem Solving
(International Group for the Psychology of Mathematics Education, 2004)
In the present study, we assert that pictures serve four functions in problem solving: decorative, representational, organizational and informational. We, therefore, investigate the effects of pictures based on their ...
Role of Schemas in One-Step Word Problems
(1999)
This study focuses on the structures and relationships involved in one-step additive and multiplicative problems. Thirty-three problems were given to 450 students in grades 2, 3 and 4. The analysis of results showed that ...
Striving for the 'grand theory': Response to the commentators
(Blackwell Publishing, 1999)
Responds to comments by F. Marton (see record rid]2000-00993-002/rid]), R. J. Sternberg (see record rid]2000-00993-003/rid]), C. F. M. van Lieshout (see record rid]2000-00993-004/rid]), E. C. Hair and W. G. Graziano (see ...
Students' Solution Strategies in Spatial Rotation Tasks
(2002)
One hundred and seven 5th-8th graders were tested on spatial rotation multiple-choice items to determine age and gender differences in spatial ability. Thirty-one of them were subsequently interviewed. They were asked to ...
Process analysis of planning in Grade 4 and Grade 8 students
(1997)
Studied how children solved a complex and knowledge-lean Crack-the-Code task using both product (accuracy and performance time) and protocol data (think aloud protocols). Participants were 8 children from 2 different grade ...
Methylphenidate and problem solving in children with ADHD: Does equal outcome mean equal process?
(2001)
This study examined between-group differences in planning of 9 grade 6 children with attention deficit hyperactivity disorder (ADHD) who were on stimulant medication and a matched comparison group of 9 without ADHD on a ...
Algebraic and Geometric Approach in Function Problem Solving
(International Group for the Psychology of Mathematics Education, 2004)
This study explores students algebraic and geometric approach in solving tasks in functions and the relation of these approaches with complex geometric problem solving. Data were obtained from 95 sophomore pre-service ...
A Modeling Perspective on the Teaching and Learning of Mathematical Problem Solving
(Mathematical Thinking and Learning: An International Journal, 2008)
This study analyzed the processes used by students when engaged in modeling activities and examined how students' abilities to solve modeling problems changed over time. Two student populations, one experimental and one ...
Thinking about Complex Problems with Modeling Software: the Role of Cognitive Style and Visual and Textual Representations
(International Association for Development of the Information Society (IADIS), 2004)
Sixty-five undergraduates, classified into Field-Dependent (FD), Field-Mixed (FM), and Field-Independent (FI) learners, were randomly assigned to two groups, Text-Only (T-O) and Text-and-Visual (T-V). The T-O group received ...
