Systems thinking and abstract thinking are important skills for engineers in general and hardware and software engineers in particular. Systems thinking emphasises the interdependence of system components and their synergy. Abstract thinking permits one to focus on the significant details of the current perspective, while temporarily neglecting…

A fundamental aspect of statistical inference is representation of real-world data using statistical models. This article analyzes students' articulations of statistical models and modeling during their first steps in making informal statistical inferences. An integrated modeling approach (IMA) was designed and implemented to help students…

Explanations are considered to be key aids to understanding the study of mathematics, science, and other complex disciplines. This paper discusses the role of students' explanations in making sense of data and learning to reason informally about statistical inference. We closely follow students' explanations in which they utilize their experiences…

To investigate the relationship between cognitive and social functioning, 20 Israeli individuals with HFASD aged 8-12 and 22 age, maternal education, and receptive vocabulary-matched preadolescents with typical development (TYP) came to the lab with a close friend. Measures of abstract reasoning, friendship quality, and dyadic interaction during a…

The authors shed light on individuals' development of the ability to use thematic and containment relations to organize concepts hierarchically. The authors used a new paradigm calling for the organization of word concepts into a containment-relation-oriented (CRO) hierarchy to collect data from 120 individuals at varied educational levels (Grade…

A model for processes of abstraction, based on epistemic actions, has been proposed elsewhere. Here we apply this model to processes in which groups of individual students construct shared knowledge and consolidate it. The data emphasizes the interactive flow of knowledge from one student to the others in the group, until they reach a shared…

A logical thinking test containing logical fallacies was administered to groups of 16-year-old and 17-year-old students (N=437) in Austria, Israel, and the Philippines. Students considered very able performed satisfactorily when required to choose a logically sound option, but exhibited weak performance when test items required a logically…

Three basic orientations to problem solving are defined and related to four profiles of problem environment. The contingency between problem-solving orientations and problem environment is presented by means of three formal models that are translated to fit the students' learning environment. Implications for further studies are discussed. (JD)

In a study, few subjects accepted empirical evidence of nonconservation of discontinuous quantity and weight. These findings were interpreted as support for the organismic-developmental claim that lower forms of reasoning are transformed into structurally more advanced forms. (Author/ED)

Eighty-seven fifth graders in Israel were randomly assigned to four different filmmaking courses, covering photography only, scenario design and photography, editing and photography, or all three activities. Filmmaking had a significant effect on the cultivation of eight mental skills. The editing activity cultivated four logical inference skills.…

Describes an Israeli reading program for disadvantaged adolescents based on verbal exercises using informative, literary, and speculative texts to improve their reading comprehension and cognitive functions. (HOD)

The moral reasoning of Israeli Jewish, Israeli Bedouin, and Palestinian school children (N=93) who had been exposed to varying degrees of political violence and socioeconomic advantage was evaluated. Mutual solutions to moral dilemmas were given more frequently by Israeli Jewish children than Israeli Bedouin or Palestinian children as questions…

Lawson's test was used with 66 ninth grade and 63 tenth grade students. Results show: that boys outperformed girls; a small correlation between achievement in science and mathematics and the Lawson test; and that Israeli students achieved significantly higher than United States students on the Piagetian skills measured by the test.

This article presents research on students' understanding of basic concepts in Graph Theory. Students' understanding is analyzed through the lens of the theoretical framework of reducing abstraction (Hazzan, 1999). As it turns out, in spite of the relative simplicity of the concepts that are introduced in the introductory part of a traditional…

Assesses the ability of tenth grade students (n=364) to acquire meanings of graphs that are frequently used in their biology textbooks. Indicates that the main source of failure to process information equally well from tables and graphs was not a lack of basic analytical skills but rather a lack of understanding of the relationship between…
