Computational thinking (CT) has been advocated as an essential problem solving skill students need to develop. Emphasizing on CT applied in both programming and everyday contexts, we developed a humanoid robotics curriculum and a computerized assessment instrument. We implemented the curriculum with six classes of 125 fifth graders. Quantitative…

Mathematical problems can be divided into two types, namely, process-open and process-constrained problems. Solving these two types of problems may require different cognitive mechanisms. However, there has been only one study that investigated the differences of the cognitive abilities in process-open and process-constrained problem solving, and…

While AI has become more prevalent in our society than ever, many young learners are found holding various naive, erroneous conceptions of AI due to the influence of their technology and media environments. To address this issue, this study seeks to propose a novel pedagogical solution to improve upper-elementary school students' scientific…

Mathematical reasoning requires perseverance to overcome the cognitive and affective difficulties encountered whilst pursuing a reasoned line of enquiry. The aims of the study were: to understand how children's perseverance in mathematical reasoning (PiMR) manifests in reasoning activities, and to examine how PiMR can be facilitated through a…

Scientific reasoning abilities are already developing in elementary-school-aged children and enable them to understand the world around them. The goal of the current study was to develop a new instrument for 8- to 10-year-old children in Grades 3 and 4 to measure their understanding of the steps of the "scientific inquiry cycle" (SIC).…

This study's hypotheses were that (a) word-problem (WP) solving is a form of text comprehension that involves language comprehension processes, working memory, and reasoning, but (b) WP solving differs from other forms of text comprehension by requiring WP-specific language comprehension as well as general language comprehension. At the start of…

Using multitrait, multimethod data, and confirmatory factor analysis, the current study examined the effects of arithmetic item formatting and the possibility that across formats, abilities other than arithmetic may contribute to children's answers. Measurement hypotheses were guided by several leading theories of arithmetic cognition. With a…

This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. Four hundred and forty-seven students (age mean [M] = 10.23 years, 73% boys and 27% girls) from an elementary school district in the US southwest participated. Structural equation modelling tests indicated that…

A study conjectured that individuals make mental models of events when they reason from premises involving temporal relations. Several experiments using school children and university students as subjects found that problems that required one mental model elicited more correct responses than problems that required multiple mental models.

Recognition errors of children in Grades 2, 4, and 6 were examined. Subjects learned words under intentional or incidental instructions and were tested immediately or 48 hours later. Subjects had to choose a target word from among acoustic, conceptual, associative and neutral distractors. The immediate recognition of 2nd-grade subjects was…

Employed regression analysis to determine the association between multiplicative classification and inductive reasoning. Subjects were 103 fourth grade children. (SDH)

An experiment concerning children's conceptions of price was conducted to investigate the influence of the context of a problem on its apprehension. A total of 120 children of several age groups (nursery school, grades 2, 4, and 6) were interviewed individually. An initial question was asked ("Why does a bun cost about one Swedish…

The development of children's comprehension of cause and effect relationships was studied in 68 kindergarten, first grade, and second grade children. (BRT)

Data from three studies with elementary and junior high school students are presented in support of the contention that facility in concrete operations is necessary and sufficient for competence in the simple syllogistic forms, while formal operations are required when dealing with conditional statements in certain more complex contexts.…

Two studies with first- and fifth-grade children in two learning tasks showed that preoperational children did not necessarily learn responses followed by a stimulus object previously instrumental in obtaining a reward, while postoperational subjects did. (Author/JMB)
