Cognitive development of eighth-grade students, as identified by Jean Piaget, occurs during a time when many of them are transitioning between concrete operations and formal operations where the ability to think in abstract concepts becomes possible. Because of this period of transition, many eighth-grade students find difficulty in demonstrating…

This paper investigated how production task combined with teacher feedback (in the form of recasts) affects child second language development, and the effects of task complexity on their production performance. 92 child learners of English in three intact classes were assigned to three tasks of different complexity (simple, +complex, ++complex).…

Critical thinking skills are the 21st-century life skills that are needed by students. However, in elementary schools, there are no instruments that are truly effective and efficient to measure critical thinking skills. This research aims to develop an open-ended question assessment instrument to measure students' critical-thinking skills, to test…

How people see the world, even how they research it, is influenced by beliefs. Some beliefs are conscious and the result of research, or at least amenable to research. Others are largely invisible. They may feel like "common knowledge" (though myth, not knowledge), unrecognized premises that are part of the surrounding culture. As we…

We share ideas for preparing for and enacting high-cognitive demand tasks in ways that support students in articulating and justifying their ideas. We offer strategies for developing and posing several types of purposeful questions: (1) eliciting thinking, (2) generating ideas, (3) clarifying explanations, and (4) justifying claims.

Learning, development, and response to instruction often involve changes in the strategies that learners use to solve problems. In this chapter, our focus is on mathematical problem solving in both children and adults. We offer a selective review of research on three classes of factors that may influence processes of strategy change in…

"Teaching, Learning and Psychology" offers comprehensive coverage of contemporary psychological issues and new directions in education. With its focus on the non-deficit nature of human behaviours and positive psychology, the book emphasises the importance of appropriate pedagogical practices for effective learning. Comprehensive and…

This dissertation documents a new way of conceptualizing vectors in college mathematics, especially in geometry. First, I will introduce three problems to show the complexity and subtlety of the construct of vectors with the classical vector representations. These highlight the need for a new framework that: (1) differentiates abstraction from a…

This research explored online graduate students' preferences using the Constructivist Internet-Based Learning Environment Survey (CILES) and how everyday learner attributes affected their preferences. The purpose of this study was to identify graduate students' preferences for various types of learning in order to aid designers with aligning…

This chapter examines the various cognitive tools embedded in a multimedia-enriched PBL environment for middle school science known as "Alien Rescue" and shares the research findings of the use of these cognitive tools in assisting young learners' problem solving. The goal of this chapter is to illustrate strategies for designing…

Research on young children and their understanding and use of models indicates that they have particular difficulty understanding and using symbols that are in themselves interesting objects (have dual representation). Implications for the use of symbols for educational purposes are discussed, reviewing several commonly used symbolic objects. (SLD)

This paper suggests that a change in mode of expression --narrative, descriptive, or expository--can influence the syntactic complexity of children's writing. The implications of the research studies reviewed here may offer direction for education in general. Instructional strategies which make use of variation in writing mode to encourage gains…

A study assessed the cognitive level of academic challenges incorporated into courses offered in the College of Agricultural Sciences at the Pennsylvania State University. Eleven faculty members from nine departments provided copies of all academic challenges used in their courses. They were categorized by type: activities, problem sets, written…

This paper describes a framework for researching the Cognition Hypothesis which claims that pedagogic tasks be sequenced for learners on the basis of increases in their cognitive complexity. It distinguishes dimensions of complexity which increase the conceptual and linguistic demands tasks make on communication, so creating the conditions for L2…

In an effort to identify the cognitive characteristics of teachers which predispose them to attempt to increase levels of information processing in their classrooms, a theoretical construct--cognitive complexity--was synthesized from the processes of conceptual level, creativity, and categorization. Measures of constructs listed above were…
