Concept maps and Vee diagrams: two metacognitive tools to facilitate meaningful learning

This paper describes two metacognitive tools, concept mapping and Vee diagramming, and reports on research utilizing these tools from grades one through university instruction. The psychological and epistemological foundations underlying these tools is presented briefly. The issues of the dominantly rote-mode nature of much school learning and the resistance of studients (and teachers) to move to meaningful learning strategies fostered by concept mapping and Vee diagramming are discussed. The data available to date from a variety of qualitative and quantitative research studies strongly support the value of these metacognitive tools both for cognitive and affective gains.     

Competence and usage of Web 2.0 technologies by higher education faculty

Literature on Web 2.0 experiences of higher education faculty in developing countries such as Pakistan is very limited. An insight on awareness and practices of higher education faculty with these tools can be helpful to map strategies and plan of action for adopting latest technologies to support teaching–learning processes in higher education of such countries. This survey study was aimed to examine the competence and practices of higher education faculty in Pakistan with Web 2.0 technologies such as blogs, Wikis, Google Docs, Skype, Flickr, YouTube, and social networks. The study was also focused to look for what type of role faculty play while using these tools; and to find whether any significant differences in terms of age, gender, or academic discipline exist in competence and usage of these tools by the faculty. The data were collected from a sample of 246 university teachers in the spring 2014 semester. The findings of the study indicated that faculty participants reported to use Web 2.0 social tools more frequently than instrumental tools. Similarly, their competence with social tools was higher than their competence with instrumental tools. Additional results indicated that their competence with Web2.0 tools significantly differed with respect to their age, gender, and academic disciplines.     

Rethinking the Role of Information Technology-Based Research Tools in Students’ Development of Scientific Literacy

Given the central place IT-based research tools take in scientific research, the marginal role such tools currently play in science curricula is dissatisfying from the perspective of making students scientifically literate. To appropriately frame the role of IT-based research tools in science curricula, we propose a framework that is developed to understand the use of tools in human activity, namely cultural-historical activity theory (CHAT). Accordingly, IT-based research tools constitute central moments of scientific research activity and neither can be seen apart from its objectives, nor can it be considered apart from the cultural-historical determined forms of activity (praxis) in which human subjects participate. Based on empirical data involving students participating in research activity, we point out how an appropriate account of IT-based research tools involves subjects’ use of tools with respect to the objectives of research activity and the contribution to the praxis of research. We propose to reconceptualize the role of IT-based research tools as contributing to scientific literacy if students apply these tools with respect to the objectives of the research activity and contribute to praxis of research by evaluating and modifying the application of these tools. We conclude this paper by sketching the educational implications of this reconceptualized role of IT-based research tools.

Cognitive Tools in a Clinical Encounter in Medicine: Supporting Empathy and Expertise in Distributed Systems

This paper examines how, in use, culturally-provided tools can be said to embody knowledge and distribute thinking. It focuses on the routine procedures used by medical professionals to investigate patient complaints and examines explicit and implicit contributions of these conventional procedures to distributed thinking in clinical encounters in medicine. After characterizing these tools, examples of how the tools guide and constrain medical problem solving are provided. The tools support the development and exercise of the routines characteristic of medical expertise, while at the same time preserving the nonroutine, controlled deliberation necessary for sound and ethical medical care. The paper concludes with ways in which the tools' role in thinking can be promoted through medical education, particularly during students' early clinical exposure: (a) Organizing learning experiences that expose the tools' meanings; (b) exploiting the benefits of small group work to promote collaborative and individual competencies in distributed systems; and (c) explicitly utilizing the products of thinking with these tools to further the goals shared by participants in clinical encounters.     

Learning How to Believe: Epistemic Development in Cultural Context

Although Intelligent Tutoring Systems (ITSs), also called knowledge-based tutors, are becoming more common and proving to be increasingly effective, each one must still be built from scratch at a significant cost. At the University of Massachusetts, Amherst, we have developed domain independent tools for authoring all aspects of a knowledge-based tutor: the domain model, the teaching strategies, the student model, and the learning environment. In this article, I describe these tools, discuss a number of design issues and design tradeoffs that are involved in building ITS authoring tools, and discuss knowledge acquisition and representation issues encountered in my work. I also describe how we plan to use these tools (collectively called Eon), including ontology objects, as a meta-authoring tool for designing special-purpose authoring tools tailored for specific domain types.     

A methodology for integrating computer‐based learning tools in science curricula

This paper demonstrates a methodology for effectively integrating computer‐based learning tools in science teaching and learning. This methodology provides a means of systematic analysis to identify the capabilities of particular software tools and to formulate a series of competencies relevant to physical science that could be developed by means of these capabilities. This analysis could inform the transition to technology‐rich learning environments by helping to deflect reliance on computer‐based tools for objectives they cannot meet, while encouraging the design of activity sequences that make the most of the educationally useful capabilities of available computer‐based tools. This methodology is demonstrated by means of two software tools widely used in science learning, namely modelling and simulation tools.
