The purpose of this study was to examine the differences between Finnish and Taiwanese textbooks for grades 7 to 9 on the topic of solving systems of linear equations (simultaneous equations). The specific textbooks examined were TK in Taiwan and FL in Finland. The content analysis method was used to examine (a) the teaching sequence, (b)…

This paper explores the algebraic expressions of deaf learners as they explore and construct sequences using the digital microworld Mathsticks. More specifically, it attempts to identify how the deaf students coordinated bodily, discursive and digital resources in order to attribute their own personal senses to the notion of variable. Examples of…

This study investigated the reading behavior of 15-year-old students while reading texts and answering corresponding multiple-choice questions. The availability of the texts during question answering was manipulated experimentally. Allocation of resources to several cognitive processes at the word, sentence, and text level was measured by…

In the present study, I examine a modelling strategy as employed by a teacher in the context of an algebra lesson. The actions of this teacher suggest that a modelling approach will have a greater impact on enriching student learning if we do not lose sight of the need to manage associated cognitive loads that could either aid or hinder the…

This article is explorative in its attempt to define vulnerability within transformative pedagogy by analysing excerpts from two "volatile conversations" on racism and xenophobia between a teacher and her grade nine class in a well-resourced Jewish school. The two conversations differed in regard to the teacher's use of vulnerability, even though…

The decline of physical activity during adolescence is not well understood. This prospective study followed 969 Taiwanese students from eighth to ninth grade and examined their physical activity-related cognitions, interpersonal influences, and behavior of physical activity across the grade transition. Gender differences were found in the effects…

The paper considers a teaching experiment carried out with secondary school students (9th grade), who face modelling tasks to approach some basic concepts of algebra and early calculus. The focus is on an embodied analysis of students' cognitive processes. The analysis highlights the use of metaphors as a means of sharing knowledge. (Contains 2…

This study of the Apple Classroom of Tomorrow (ACOT) environment focused on the potential of a computer-saturated environment to facilitate students' thinking processes. Four approaches were used: (1) a longtitudinal approach to study student growth and development; (2) observations of students' behavior while writing with the computer to study…

A new test theory for performance-based assessment is proposed. Criteria for "good" performance-based items, ways of measuring cognitive complexity, methods for determining maturity levels of understanding, and scaling systems are discussed. A performance-based task completed by 51 ninth and tenth graders in June 1993 was studied.…
