Evidence for the superiority of guided instruction is explained in the context of our knowledge of human cognitive architecture, expert-novice differences, and cognitive load. Although unguided or minimally guided instructional approaches are very popular and intuitively appealing, the point is made that these approaches ignore both the structures…

The racially tinged Confederate flag debate in South Carolina is viewed as a signifier of more popular struggles over the representation of "southern heritage" and under girds the social studies unit described in this paper. The unit was designed to teach the curriculum from a popular cultural, issues-oriented perspective using critical…

In this article Denise Chilvers and Angela Cole describe a school-based study which is located very much in an action-research idiom. Starting from a questioning, but collegial, stance on identifying positive interventions for children who challenge, the authors illustrate how theory and reflection on practice can lead to significant innovations…

Sixth and eighth grade students who are English language learners must be able to read and interpret 39 math word problems in order to successfully calculate the answers on the Massachusetts state math assessment (MCAS). The first year that MCAS was administered, many ELL students read the questions, found them confusing, and left them blank,…

This article questions whether popular approaches to the assessment of technology integration with classroom instruction are valid. The article explores Messick's (1993) conceptualisation of consequential validity, in an attempt to understand what validity must be evident when the integration of technology with classroom instruction is assessed.…

This paper reports the investigation of the effectiveness of Problem-Based Learning (PBL) within a web-based environment in the delivery of an undergraduate Physics course. The effectiveness was evaluated by comparing the performances and the perceptions of the sample students (n=67) using the web-based PBL and comparing the outcomes with those of…

This study makes use of an action research paradigm to improve primary students' analyzing skills. It was conducted at the San Esteban Elementary School, Region I, Philippines, during the 6-week off campus practice teaching of one of the researchers. Sources of data include a thinking skills checklist, a set of Curriculum Support Materials (CSM),…

The following article gives a brief account of some empirical research done in the 1980s in the UK by the present author with his colleague, Ibrahim Abdel-Ghany of Minia University, Egypt. At the time both researchers were working at the University of East Anglia at Norwich, England. This work is partly based on empirical arguments, and on…

This study involved an investigation of the relationship between the kinds of solution representations Chinese and U.S. students use and the sorts of pedagogical representations Chinese and U.S. teachers use during instruction. The findings suggest that the representations teachers use influence the representations their students use and, hence,…

Student success in solving physics problems is related to the representational format of the problem. We study student representational competence in two large-lecture algebra-based introductory university physics courses with approximately 600 participants total. We examined student performance on homework problems given in four different…

In a recent study we showed that physics students' problem-solving performance can depend strongly on problem representation, and that giving students a choice of problem representation can have a significant impact on their performance [ P. B. Kohl and N. D. Finklestein, Phys. Rev. ST. Phys. Educ. Res. 1, 010104 (2005) ] In this paper, we…

Students sometimes have difficulty in mathematics because they solve problems mechanically, without understanding the ideas represented by their equations. This brief note provides mathematics instructors with ideas for rectifying this fundamental flaw in students' paradigm of problem solving. (Contains 1 footnote.)

This article argues that an important source of the difficulties posed by particular concepts and theories is the narrow range of "types of causal models" with which most learners are familiar. Most learners are familiar with relatively simple styles of causal models, but many concepts and theories in science depend on styles…

Aging is often thought of as an essentially biological process and therefore a matter for the natural sciences, but that notion constitutes a very narrow view of aging. The longevity revolution of the past century and how it affects each individual and all societies can only be understood if we also draw on the social sciences. When the young…

The tendency to generalize from specific experiences leading to new, more abstract concepts is a natural aspect of human thought. Generalizations are the end result of an inductive process that begins with the identification of similarities in seemingly disparate situations. It is the existence of such generalizations that makes it possible for us…
