In this article, we examine the mental processes and representations that are required of laypersons when learning about science issues from texts. We begin by defining scientific literacy as the ability to understand and critically evaluate scientific content in order to achieve one's goals. We then present 3 challenges of learning from science texts: the intrinsic complexity of science phenomena, the need to coordinate multiple documents of various types, and the rhetorical structure of the texts themselves. Because scientific information focuses on models, theories, explanations, and evidence, we focus on how explanatory and argumentative texts are processed. Then we examine 2 components of executive control in reading—goal-directed guidance and evaluation of content—that readers can acquire and adopt to deal with these challenges. Finally, we discuss 3 implications that these theories and empirical findings have for interventions intended to improve laypersons’ understanding of scientific information. 相似文献

This paper reports the results and insights ofan exploratory investigation of theeffectiveness of a prototypic virtualproblem-based learning (VPBL) exercisedelivered via the WWW, that uses HypermediaAssisted Instructional Technologies (HAIT). The study targeted all first year medicalstudents at a south-central University Schoolof Medicine who were enrolled in the humanphysiology course during the Spring 2000 (n =150). A quasi-experimental, post-test onlyresearch design compared the VPBL and atext-based version of the same PBL exercise onstudents' achievement, as measured by a set ofselected physiology examination items, andtheir perceptions of the learning environment,as measured by the Teaching and LearningEnvironment Questionnaire (TLEQ) (Chauvin &Bowdish, 1998). Findings suggest that the VPBLis equally as effective as the text-basedversion for enhancing students' learning andtheir learning environment in small group, PBLsessions. In this paper, we examine theevidence supporting the VPBL innovation andexplore what constitutes necessary andsufficient evidence that an educationalinnovation should be incorporated appropriatelyinto the medical educational practice of aschool. We examine instructional design issuessuch as learner control, instructional control,and teacher and learner roles as related toinstructional development for the WWW, bycomparing and contrasting our observations ofthe VPBL design experiment with theprofessional literature. 相似文献

In the two decades since Audre Lorde (1984) pointed out that we have no patterns for relating across our differences as equals (p. 115), struggles to transform higher education have come to focus on communication about and across differences. Despite these efforts, conversations in higher education about group difference and equity too often exacerbate feelings of cynicism and disenfranchisement. In this article we discuss research into the actual discourses at work in communication about the cultural politics of institutional practices. We report on an analysis of qualitative data, using this data to help clarify the challenges of relating across differences as equals.Patrick Bruch is Assistant Professor of Writing Studies in the General College at the University of Minnesota, Twin Cities.
