Piaget's theory of stage structure is synonymous with discussions involving cognitive development. As with any theoretical model, researchers inevitably and rightly seek to affirm and/or contest the elements of the model presented. In this comparative study, students' performance across three hands-on engineering tasks for two distinct student…

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…

Determining the level of difficulty and student development is important in the learning continuum, especially the anatomical and physiological aspects. This study aimed to collect teachers' opinions about the learning continuum of anatomical and physiological aspects based on its difficulty level. This survey research was conducted in the cities…

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.

One of the overlapping curriculum designs indicates the mismatch of teaching materials with the cognitive level process and student development, impacting the unstructured qualification of mastery of the material. On the other hand, the breadth and depth of teaching materials in the curriculum must be following students' mental development and…

The belief that studying mathematics improves reasoning skills, known as the Theory of Formal Discipline (TFD), has been held since the time of Plato. Research evidence supports this idea, at least in the context of students who had chosen to study post-compulsory mathematics. Here we examined the development of reasoning skills in 16- to…

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…
