In this study, the effects of eliciting positive and negative emotions on various cognitive functions of four- to five-year-old preschool children were examined. Emotions were elicited through presentations of "happy" and "sad" video clips, before the children performed the cognitive tasks. Behavioural (facial expressions) and…

Based on the writing and oral reports of a group of 15 students in a graduate course focused on autobiographic writing and professional development, I address the question of how graduate study in education might sustain teachers in their work. For the course in question, the students studied recent research on teacher learning and devoted time to…

Do some forms of student (and school) assessment hinder the introduction of innovative educational practices and the development of innovation skills in education systems? This report focuses on the impact of high-stake summative assessment on innovation and argues that it is possible to reconcile high-stakes assessments and examinations through…

Functions are all around us, disguised as actions on concrete objects. Composition of functions, too, is all around us, because these actions can be performed in succession, the output of one serving as the input for the next. In terms of Gray and Tall's (2001) "embodied objects" or Lakoff and Nunez's (2000) "mathematical idea…

The masked priming paradigm was used to examine the role of the root and verb pattern morphemes in lexical access within the verb system of Arabic. Three groups participated in the study: grade 6 dyslexics, a reading-level-matched group and grade 6 normal readers. The first group consisted of: 28 grade 6 reading disabled (RD) students, 8 girls and…

A sample of 196 participants (mean age 45.94 years, 54% women) completed inventories assessing upward and downward positive and negative social comparisons and general well-being. Widows and widowers were higher on upward negative comparisons than divorced or married persons while being lower on well-being measures of life satisfaction and…

This study investigates algebraic reasoning and self-regulation skills among elementary school teachers who participated in a professional development program either with IMPROVE metacognitive questioning (PD + Meta) or with no metacognitive guidance (PD). Sixty-four Israeli teachers participated in a 3-year program designed to enhance…

Students frequently misconceive the process of problem-solving, expecting the linear process required for solving an exercise, rather than the convoluted search process required to solve a genuine problem. In this paper we present an activity designed to foster in students realization and appreciation of the nature of the problem-solving process,…

This paper focuses on the cognitive processes that occur while students are exploring motion graphs. In a classroom experiment, we examine how high-school students (aged 17), with backgrounds in calculus and physics, interpret the graphs they create through drawing the path of the movement of their hand with a computer mouse. Based on recent, and…

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…

Variability stands in the heart of statistics theory and practice. Concepts and judgments involved in comparing groups have been found to be a productive vehicle for motivating learners to reason statistically and are critical for building the intuitive foundation for inferential reasoning. The focus in this paper is on the emergence of beginners'…

Explores what it means to think in a target language, discusses those factors determining planned and unplanned use of more than one language for thinking, considers the role of target-language thinking in improving language ability, and examines mental translation in the reading of intermediate college French. The article concludes that benefits…
