This study aims to examine the changes in students' mental constructions of function transformation based on the designed activities, classroom discussions, exercises (ACE) teaching cycle in the light of the action, process, object, schema (APOS) theoretical framework. The study was conducted by seven volunteer students who were enrolled in…

This paper discusses the significance of model-based teaching on the topic of ionic and metallic bonding in Year 12 Chemistry in a New Zealand secondary school. Based on the conceptualization of the sub-macro level understanding of the bonding structure and properties of ionic and metallic compounds, models and drawings were used as an effective…

Due to their abstract nature, representation of mathematical concepts through different registers favors their understanding. In the case of ''sequences and regularities'', it becomes propitious the exploration of different registers of representation in the institution of topics, such as term, order, formation law, and generating expression.…

"That was the day I decided I was bad at math." Countless times, preservice and in-service teachers make statements such as this after sharing vivid memories of learning multiplication facts. Timed tests; public competitive games, such as Around the World; and visible displays of who has and has not mastered groups of facts still…

As an important subject in the curriculum, many students find chemistry concepts difficult to learn and understand. Chemical bonding especially is important in understanding the compositions of chemical compounds and related concepts and research has shown that students struggle with this concept. In this theoretical paper based on analysis of…

The distinction between procedural and conceptual learning has long been a topic of discussion in mathematics education and the idea of compression into thinkable concepts that enable the individual make links between them (Tall, 2007). In addition to, the compression to thinkable concept was to be thinking mechanism arising naturally and…

Five Canadian high school Chemistry classes in one school, taught by three different teachers, studied the concepts of dynamic chemical equilibria and Le Chatelier's Principle. Some students received traditional teacher-led explanations of the concept first and used an interactive scientific visualisation second, while others worked with the…

This article draws its data from a collaborative intervention project "Expanding Textual Repertoires," which sought to help English teachers develop their students' higher-order work with language and texts in Singapore secondary schools. The focus is on the strategy of weaving, a form of connection-making which involves the deliberate…

The premise underlying this article is that identifying and using the "five practices model" can make discussions of cognitively challenging tasks more manageable for teachers. By giving teachers a roadmap that they can follow before and during whole-class discussions, these practices have the potential for helping teachers more effectively…

The instructional design presented in this article discusses a procedure for arranging and sequencing examples and nonexamples for concept teaching in the classroom. Concepts are divided into two types: definition and observation. A definition concept is one in which the critical attributes are determined by the definition, e.g., war. Observation…

The study compared two methods of teaching an initial place value skill: a concrete, semiconcrete, abstract teaching sequence and an abstract-only presentation. Learning-disabled elementary and middle school students (N=24) using the concrete to abstract teaching sequence performed significantly better on three posttests than students taught the…

Barnes and Clawson's presentation of Ausubel's theory of meaningful learning (Review of Educational Research, 45, 1975, pp. 637-59) is misleading, according to the author. He states that Ausubel's crucial point is not that organizers relate new knowledge to an existing cognitive structure, but that new learning materials can only be considered…

Discusses the attempt to provide youngsters in inner-city schools with the kinds of experiences which permit the exploration of future roles without premature commitments, and to help them make decisions with optimism and self-knowledge. (RB)

Educational psychology undergraduates were taught in alternating instructional sequences; one sequence was a conceptually oriented lecture followed by a factually oriented self-study, the other sequence was a factual self-study followed by a conceptual lecture. Results more closely supported the predictions derived from the educational set…

Presented is a list of developmental and sequential skills and concepts for preschool through grade 6 students, which can serve as a general guide to presenting and reinforcing globe and earth science basic ideas and related activities. (Author/KC)
