Given the difficulty of teaching Cambodian learners the English speaking skills due to large, mixed-ability classes, and inappropriate applications of existing resources, the approach of Task-Based Instruction (TBI) was tested with ninth-grade students. This article, therefore, investigates the effect of TBI on ninth-graders' English-speaking…

Learning in general education contexts enhances access to general curriculum content for students with disabilities. However, few intervention studies focused on general education content have been conducted in general education settings. The current study provides preliminary evidence of the effectiveness of a literacy intervention using…

This study was an attempt to assess how learners of English as a foreign language (EFL) improved their speaking fluency in a task-based language teaching (TBLT) approach used with ninth-grade learners at PUNIV-Cazenga, a high school in Luanda. In a case study design that used picture-description tasks, learners' speeches were audio recorded before…

This article presents an examination of the language demands of cognitively demanding tasks and proposes an initial framework for the language demands of higher-order mathematics thinking practices. We articulate four categories for this framework: "language of generalisation," "language of comparison," "language of proportional reasoning," and…

We studied developmental trends in 5 important reasoning tasks that are critical components of the operational definition of rational thinking. The tasks measured denominator neglect, belief bias, base rate sensitivity, resistance to framing, and the tendency toward otherside thinking. In addition to age, we examined 2 other individual difference…

The study examined the knowledge of the functional relations between potential difference, magnitude of current, and resistance among seventh graders, ninth graders, 11th graders (in technical schools), and college students. It also tested the efficiency of a learning device named "functional learning" derived from cognitive psychology on the…

Coordinate graphs of time-series data have been significant in the history of statistical graphing and in recent school mathematics curricula. A survey task to construct a graph to represent data about temperature change over time was administered to 133 students in Grades 3, 5, 7, and 9. Four response levels described the degree to which students…
