Solving new problems can be made easier if one can build on experiences with other problems one has already successfully solved. The ability to exploit earlier problem-solving experiences in solving new problems seems to require several cognitive sub-abilities. Minimally, one needs to be able to retrieve relevant knowledge of earlier solved…

The natural-language tutorial dialogue system that the authors are developing will allow them to focus on the nature of interactivity during tutoring as a malleable factor. Specifically, it will serve as a research platform for studies that manipulate the frequency and types of verbal alignment processes that take place during tutoring, such as…

This study investigated the mental representations of student and professional engineers while they solved an engineering design problem. The intent was to gain a deeper insight into the differences that exist in the cognitive processes of engineering students and professional engineers as they use mental representations (i.e., propositions,…

In many competitive sports, players try to deceive their opponents about their behavioral intentions by using specific body movements or postures called fakes. For example, fakes are performed in basketball when a player gazes in one direction but passes or shoots the ball in another direction to avert efficient defense actions. The present study…

This research applied social domain theory to illuminate reasoning about the perceived legitimacy and limits of group decision making (majority rule) among adolescents from urban and rural China (N = 160). Study 1 revealed that adolescents from both urban and rural China judged group decision making as acceptable for both social conventional and…

This paper focuses on a training program in inductive reasoning for first-grade students and presents the direct results as well as the longitudinal effects of the evaluation study. The training is based on Klauer's theory of inductive reasoning and on his "Cognitive training for children" concept (Klauer, 1989a). The training program consists of…

Given that most economies are now in recession, policymakers are looking to small firms to act as engines of economic growth; this has led to a revived interest in the role of enterprise policy. The "new" enterprise policy is systemic, promoting and shaping externalities and capabilities. At its core are R&D, innovation and education. It…

The two main statements of the second law of thermodynamics were given by Clausius, and Kelvin and Planck. Other statements followed well into the 20th century. It is known that the two main statements are not exactly equivalent, although their differences may never show outside academic environments or very specific areas of science. At negative…

Over the course of the past decade, contradictory claims have been made regarding the neural bases of deductive reasoning. Researchers have been puzzled by apparent inconsistencies in the literature. Some have even questioned the effectiveness of the methodology used to study the neural bases of deductive reasoning. However, the idea that…

This paper is written to draw attention to the ideal knower and the logic of knowledge embedded in curricula. New logics and new knowers, I argue, are conjured with the hope they will be capable of succeeding in curriculum designers' imagined future. I frame this discussion in terms of debates about the place of knowledge in the sociology of…

In this dissertation, I defend "semantic singularism", which is the view that syntactically plural terms, such as "they" or "Russell and Whitehead", are semantically singular. A semantically singular term is a term that denotes a single entity. Semantic singularism is to be distinguished from "syntactic singularism", according to which…

This paper begins by suggesting that issues of social and ecological justice are not mutually exclusive. They are tied together through the logic of domination which is, in turn, sustained by oppositional value dualisms such man/woman, human/nature, and white/non-white. As such, we suggest that environmental education must deal with the shared…

The relation between types of tasks and the mathematical reasoning used by students trying to solve tasks in a national test situation is analyzed. The results show that when confronted with test tasks that share important properties with tasks in the textbook the students solved them by trying to recall facts or algorithms. Such test tasks did…

The ability to think logically is a hallmark of human intelligence, yet our innate inferential abilities are marked by implicit biases that often lead to illogical inference. For example, given AB ("if A then B"), people frequently but fallaciously infer the inverse, BA. This mode of inference, called symmetry, is logically invalid because,…

The ability to successfully discriminate between multiple potentially relevant source analogs when solving new problems is crucial to proficiency in a mathematics domain. Experimental findings in two different mathematical contexts demonstrate that providing cues to support comparative reasoning during an initial instructional analogy, relative to…
