In this work is proposed that an adaptation tool that is for the automatic generation and personalization of courses of a general-purpose LCMS that is named A Tutor. A Tutor is a Learning Content Management System. The architecture of the adaptation tool that allows a personalized sequencing of LOs in A Tutor for the learner's learning goals,…

It is common to find students believing that they have a high skill level in computer use yet this does not normally include proficiency in the use of computer packages for data presentation. This exercise develops team work in data collection, requires the production of a simple spreadsheet, and the exporting of the data from that into one or…

The orbitofrontal cortex (OBFc) has been suggested to code the motivational value of environmental stimuli and to use this information for the flexible guidance of goal-directed behavior. To examine whether information regarding reward prediction is quantitatively represented in the rat OBFc, neural activity was recorded during an olfactory…

We examined women's participation, relative to men's, at the annual meetings of the Association for Behavior Analysis (ABA) between 1975 and 2005. Among our findings are upward trends in female presenters across formats (e.g., posters), types of authorship (e.g., first authors), and specialty areas (e.g., autism). Where women have attained…

In this paper we focus on some of the findings of the science education research community in the area of representations and problem solving. Problem solving depends on the construction and manipulation of mental models (internal representations) in the mind. A large knowledge base (declarative, procedural, strategic, situational, and schematic…

Understanding complex systems is fundamental to understanding science. The complexity of such systems makes them very difficult to understand because they are composed of multiple interrelated levels that interact in dynamic ways. The goal of this study was to understand how experts and novices differed in their understanding of two complex…

Despite a growing development of virtual laboratories which use the advantages of multimedia and Internet for distance education, learning by means of such tutorial tools would be more effective if they were specifically tailored to each student needs. The virtual teaching process would be well adapted if an artificial tutor can identify the…

The knowledge construction and scientific reasoning of two classes of seventh grade students (22 to 24 students in each class) were examined during a 3-week inquiry unit in genetics, in which anomalies were used as a catalyst for conceptual change. During the unit, students used genetics simulation software to mate fruit flies that varied on a…

This paper gives an overview of the Inspiration Software, a package that is designed to facilitate the construction and use of concept maps in the classroom. The first section discusses concept mapping, defined as any graphic production that is constructed specifically to represent knowledge. The following basic functions of Inspiration are then…

Shares perspectives on the history and current status of ethnomathematics. Speculates as to whether this field is revisionist and discusses the features of ethnomathematics that distinguish it from mathematics. (DDR)

Explores children's understandings of insect life cycles through pre- and postinstructional interviews, analysis of children's journal entries, and talk that occurred throughout the instructional unit. Contains 38 references. (DDR)

Provides further details regarding a philosophical reconstruction of the structure of Classical Genetics Theory that can facilitate problem-solving instruction. Describes how that reconstruction can facilitate realistic problem solving on the part of students. Contains 60 references. (DDR)

Explores the current images that students have of scientists, student perceptions of science study in school, and student awareness of their use of science outside of school. Fifth grade students (N=117) were the subjects of this study that asked students to sketch scientists and school science. (DDR)

Points out that today's taxonomy is very different than what many biology teachers learned when they were in school. Traces the history of some of the changes and describes the current taxonomy. (DDR)

Describes the architecture of PRABODH, an intelligent tutoring system with six components, designed for teaching language skills to young children and for providing them meaningful practice for developing grammar skills. Discusses PRABODH's language-learning philosophy, results of formative evaluation of its knowledge component, and overall impact…
