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…

This study compares alignment of the ACT and the American Diploma Project (ADP) national college readiness standards sets with the Texas Essential Knowledge and Skills for English language arts and reading (TEKS ELAR) standards for grades 9-12 and analyzes their cognitive complexity. It finds that a majority of the content in the ACT and ADP…

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…

Within the large range of potential theoretical perspectives on fractions, this paper considers one particular interpretation: fractions' duality as process and object. By considering the number-fractionbar-number composite symbol as simultaneously representing division and rational, some process-object theories imply that fraction-as-process and…

This study examined the relationship between environment-based education and high school students' critical thinking skills and disposition toward critical thinking. Four hundred four 9th and 12th grade students from 11 Florida high schools participated in the study. A Pretest-Posttest Nonequivalent Comparison Group Design (9th grade) and a…

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…
