Critical thinking is foundational to the effective teaching of any subject, and it must be at the heart of any professional development program. This chapter presents a long-term professional development model based on a substantive concept of critical thinking, and ties critical thinking to the concept of the Learning College.

How is the new industrial model of privatization, commercialization, and corporatization altering higher education's traditional mission? To provide policymakers with understanding about the traditional charter between higher education and society, this article defines the concepts of the public good underlying the charter, analyzes the new…

High-quality professional development is essential in supporting accomplished teaching. But how is the efficacy of professional development evaluated? The authors present several methods for conducting a critical analysis of professional development. Using a large-scale professional development initiative as the focal point, they first explain…

Since the publication of Fodor's (1983) The Modularity of Mind, there have been quite a few discussions of cognitive modularity among cognitive scientists. Generally, in those discussions, modularity means a property of specialized cognitive processes or a domain-specific body of information. In actuality, scholars understand modularity in many…

Student writing can provide opportunities for reflection on concept mastery for both students and teacher, and the creation of a biology portfolio by each student can allow a teacher to assess the level of understanding achieved by each individual as well as timely correction of conceptual errors. The use of portfolio is an assessment tool, which…

This study examines the role of self-regulated learning (SRL) in facilitating students' shifts to more sophisticated mental models of the circulatory system as indicated by both performance and process data. We began with Winne and colleagues' information processing model of SRL (Winne, 2001; Winne & Hadwin, 1998) and used it to examine how…

A cross-sectional study of Portuguese primary school pupils' conceptions on digestion and the digestive tract was carried out before and after teaching this topic. Pupils of the prior four school years (5/6 to 9/10 year old) drew what happens to a cookie inside their body. In some cases they also wrote a short text or were interviewed. To identify…

A technologically literate individual should be able to use, manage, and understand technological concepts and systems. A technologically literate individual should also have the capacity to design, develop, control, use, and assess technological systems and processes. These abilities are essential elements of the universals of technology, as…

Considers effective dialogue between teacher and student essential for promoting meaningful learning in the classroom. Effective dialogue enables teachers and students to be active in the construction of shared understanding by making explicit the overlap between the perspectives held by students and teachers. Suggests that concept maps provide a…

The mathematical reasons that we cannot divide by zero are not easy for most students to understand; in fact, even those students who have more than just a basic understanding of algebraic concepts still have difficulty. This is most problematic for college students who are prospective teachers since they need to develop a deep understanding of…

The research on conceptual change has so far mainly dealt with cognitive outcomes, but especially during the last few years there has been a growing interest in and discussion about the processes of conceptual change. The purpose of the article is to contribute to this discussion and to present a theoretical model of the dynamics among the…

This study explores the use of Valsiner's zone theory as a way to interpret the zones of proximal development of three secondary teachers in mathematics and science. Specifically, we used classroom discourse to identify what the participating teachers promoted (zone of promoted action) or allowed (zone of free movement) in the classroom as a way…

This study examined the relationship between characteristics of mothers' talk about future events and young children's ability to contribute to naturalistic conversations about future events. Results indicated that three maternal style factors were related to 2.5- and 4-year-olds' contributions: elaborative/advanced language, general and past…

This research explores the way in which young children (5 years of age) and adults use perceptual and conceptual cues for categorizing objects processed by vision or by audition. Three experiments were carried out using forced-choice categorization tasks that allowed responses based on taxonomic relations (e.g., vehicles) or on schema category…

People acquire spatial information from many sources, including maps, verbal descriptions, and navigating in the environment. The different sources present spatial information in different ways. For example, maps can show many spatial relations simultaneously, but in a description, each spatial relation must be presented sequentially. The present…
