Discusses a framework for assessing middle school students' thinking in conditional probability and independence. Establishes four levels of thinking from subjective to numerical reasoning for both constructs. Students (n=15) from grades 4-8 were interviewed. Profiles reveal that levels of probabilistic thinking were stable across the two…

Compares BASIC and LOGO systems in developing artificial intelligence systems. Provides listings of programs used for translating and sentence making. Describes methodology and compares the BASIC and LOGO programs. (MVL)

Explores aspects of information retrieval skills such as end user training, indexing, controlled vocabulary systems, search protocol, boolean logic, problem analysis, and decision making. Suggests techniques for classroom instruction using simulations of online databases, CD-ROMs, and DIALOG's classroom instruction program. Describes several…

Compares the relative effects of hands-on and teacher demonstration laboratory methods on declarative knowledge and procedural knowledge achievement. Reports that students in the hands-on class were better on the procedural knowledge test than students in the demonstration class. (Author/YP)

Challenges the readers comprehension of mathematical induction by presenting four examples of arguments that misrepresent the concept. Discusses the reasons why the arguments lead to false conclusions. (MDH)

Beginning geometry students misunderstand the requirements of formal proof because of confusion between deductive reasoning and argumentation. Presented is a cognitive analysis of deductive organization versus argumentative organization of reasoning and the applications of this analysis to learning. Implications of a study analyzing students'…

Human behavior is governed by assumptions and beliefs ("theory-in-use"), yet individuals commonly explain their behavior in terms of a (different) "espoused" theory. Suggests reflective practice in counseling can only be achieved by counselors identifying their own theories-in-use through critical thinking. This task also…

Many authors have argued that word-learning constraints help guide a word-learner's hypotheses as to the meaning of a newly heard word. One such class of constraints derives from the observation that word-learners of all ages prefer to map novel labels to novel objects in situations of referential ambiguity. In this paper I use eye-tracking to…

In this study, we defined and quantified the degree of cognitive conflict induced by a discrepant event from a cognitive perspective. Based on the scheme developed, we investigated the relationship between cognitive conflict and conceptual change, and the influences of students' cognitive characteristics on conflict in learning the concept of…

Designing a curriculum is much more than a technical process. Indeed, it could be called a political activity because stakeholders usually attribute different values to, and hold different expectations from, a new curriculum. As early as 1949, Tyler had raised this issue in his classic "Basic Principles of Curriculum and Instruction."…

This article describes the authors' journey as three educational leadership professors implementing a program to improve teaching for social justice. The social change agents they seek to nurture in their graduate program are individuals who are keenly aware of inequities in society and possess the knowledge, skills, and will to make a difference…

Synaptic plasticity is thought to contribute to memory formation. Serotonin-induced facilitation of sensory-motor (SN-MN) synapses in "Aplysia" is an extensively studied cellular analog of memory for sensitization. Serotonin, a modulatory neurotransmitter, is released in the CNS during sensitization training, and induces three temporally and…

Introduction: This research addresses preschoolers' intuitive understanding of rectilinear movement and some variables which affect it, and the type of arguments used when related knowledge states are justified. A first working hypothesis is that the resolution of practical, functional situations would be based on self-regulation processes. A…

This paper describes two classroom activities and a project that supplement a Liberal Arts Mathematics course's coverage of logic and reasoning. The first classroom activity introduces the writing of inductive and deductive arguments, and the second activity involves analyzing a guest speaker's arguments. The project consists of using logic and…

Commonly, the task of constructing rationales is used in development programmes as a means of advancing Further Education College (FEC) lecturers' understanding of their practice. Often lecturers also teach this task as a part of student project work. Drawing on psychological research on argumentative reasoning the aim was to illuminate strengths…
