Designing computer learning environments for engineering and computer science: The scaffolded knowledge integration framework 总被引:1,自引:5,他引:1
Marcia C. Linn 《Journal of Science Education and Technology》1995,4(2):103-126
Designing effective curricula for complex topics and incorporating technological tools is an evolving process. One important way to foster effective design is to synthesize successful practices. This paper describes a framework called scaffolded knowledge integration and illustrates how it guided the design of two successful course enhancements in the field of computer science and engineering. One course enhancement, the LISP Knowledge Integration Environment, improved learning and resulted in more gender-equitable outcomes. The second course enhancement, the spatial reasoning environment, addressed spatial reasoning in an introductory engineering course. This enhancement minimized the importance of prior knowledge of spatial reasoning and helped students develop a more comprehensive repertoire of spatial reasoning strategies. Taken together, the instructional research programs reinforce the value of the scaffolded knowledge integration framework and suggest directions for future curriculum reformers.Portions of this paper were presented at the American Psychological Association Meeting, Ontario, Canada, August 22, 1993. under the title of Cognition and instruction in higher education: Applications of advanced technologies. The title of the symposium was New Fellows in Educational Psychology-The Implications of Their Work for University-Level Instruction. This material is based upon research supported by the National Science Foundation under grant MDR-8954753. Any opinions, findings, and conclusions or recommendations expressed in this publication are those of the authors and not necessarily reflect the views of the National Science Foundation. 相似文献

We compared two forms of automated guidance to support students’ understanding of climate change in an online inquiry science unit. For specific guidance, we directly communicated ideas that were missing or misrepresented in student responses. For knowledge integration guidance, we provided hints or suggestions to motivate learners to analyze features of their response and seek more information. We guided both student-constructed energy flow diagrams and short essays at total of five times across an approximately week-long curriculum unit. Our results indicate that while specific guidance typically produced larger accuracy gains on responses within the curriculum unit, knowledge integration guidance produced stronger outcomes on a novel essay at posttest. Closer analysis revealed an association between the time spent revisiting a visualization and posttest scores on this summary essay, only for those students in the knowledge integration condition. We discuss how these gains in knowledge integration extend laboratory results related to ‘desirable difficulties’ and show how autonomous inquiry can be fostered through automated guidance. 相似文献

This study seeks to understand the experiences of women of color engineering students who persist and identify some of the
dilemmas they face. Evidence emerged that students formulate multiple identities to help them persist in their engineering
programs. We assess the role that identity plays in the experiences of STEM (science, technology, engineering, and mathematics)
women of color. This paper applies a multiple identities framework and presents students' experiences through the lenses of
three emergent identities: academic, social, and intellectual. We discuss possible implications of the findings for academic
and social support programs in higher education. We also identify some implications for precollege instruction. 相似文献

Selecting an infant feeding method is one of the most important decisions a mother-to-be makes. Little information is available to characterize women who plan to use both formula and breast milk. In this study, 89 pregnant women indicated their anticipated feeding method and the sources and initiator of infant feeding information. No differences were found in the type of resources used by women who planned to breastfeed, formula feed, or combination feed. Women in the study were four times more likely to initiate a conversation about infant feeding methods with a family member or friend than with a health care provider. Involving these key individuals in perinatal education classes and support programs is a simple, but powerful, strategy that childbirth educators can use to promote breastfeeding. 相似文献

Piaget's theory has profoundly influenced science education research. Following Piaget, researchers have focused on content-free strategies, developmentally based mechanisms, and structural models of each stage of reasoning. In practice, factors besides those considered in Piaget's theory influence whether or not a theoretically available strategy is used. Piaget's focus has minimized the research attention placed on what could be called “practical” factors in reasoning. Practical factors are factors that influence application of a theoretically available strategy, for example, previous experience with the task content, familiarity with task instructions, or personality style of the student. Piagetian theory has minimized the importance of practical factors and discouraged investigation of (1) the role of factual knowledge in reasoning, (2) the diagnosis of specific, task-based errors in reasoning, (3) the influence of individual aptitudes on reasoning (e.g., field dependence-independence), and (4) the effect of educational interventions designed to change reasoning. This article calls for new emphasis on practical factors in reasoning and suggests why research on practical factors in reasoning will enhance our understanding of how scientific reasoning is acquired and of how science education programs can foster it. 相似文献

Shame, guilt, symptoms of depression, and reported history of psychological maltreatment 总被引:1,自引:0,他引:1
OBJECTIVE: The purpose of the present study was to provide preliminary data extending earlier research on shame and guilt, examining their relationships both to symptoms of depression and to psychological maltreatment. Symptoms of depression were expected to correlate positively with shame, but not with guilt. Psychological maltreatment was also expected to correlate positively with shame. The relationship between psychological maltreatment and guilt was examined on an exploratory basis. METHOD: Two hundred and eighty participants from a public community college and a private university completed scales assessing shame, guilt, depression, and history of childhood psychological maltreatment. Pearson correlations were conducted with all data. RESULTS: Results indicated that symptoms of depression were positively correlated with both shame and guilt. Partial correlations were then conducted in which the linear effects of shame were removed from guilt. In this latter analysis, guilt was no longer positively correlated with symptoms of depression. Psychological maltreatment was also positively correlated with depression and with shame, but not with guilt. CONCLUSIONS: These results highlight the significance of psychological maltreatment in the relationship to the self-conscious emotions of guilt and shame. As in earlier studies, shame has been consistently correlated to poor psychological functioning, while guilt appears to be relatively unrelated to pathological functioning. 相似文献

ABSTRACTA multiplicity of perspectives and methods are necessary to investigate the complexities of human development and educational institutions. However, many would-be MM researchers still have questions about how to conceptualize and conduct MM research. Taking a dialectic stance, or mixing research approaches to suit the demands of a research problem, is one way to integrate multiple perspectives from conception to conclusions in a MM research study. In this spirit, we engage in a meta-dialogue focused on our use of the dialectic stance in our dissertations. Using an autoethnographic approach we now call ‘dialectic dialogue’, we analytically and reflectively reexamine our respective research processes to investigate, individually and collaboratively, how taking a dialectic stance influenced the paradigms, methodologies, and methods of our MM dissertations. Three verbal and artistic metaphors for our experience emerged from our discussion: feeling boxed in, getting lucky, and radical commitment. Each metaphor is discussed from our individual and shared perspectives. Our goal is to open our dialogue to a field-wide conversation about the dialectic stance; thus, we conclude with questions for the MM field to consider. This article will be of particular interest to newcomers to the field of MM and their mentors. 相似文献

This preliminary study examined intervention effects of a universal prevention program offered by classroom teachers to public elementary school students. The Unique Minds School Program (M.B. Stern, 1999) is a teacher‐led program designed to promote cognitive‐social‐emotional (CSE) skills, including student self‐efficacy, problem solving, social‐emotional competence, and a positive classroom climate, with the dual goal of preventing youth behavioral problems and promoting academic learning. During 2 consecutive school years, 119 students and their teachers were assessed in the fall and spring of Grade 4 and again in the spring of Grade 5. As compared to students in the comparison school, students in the intervention showed gains in student self‐efficacy, problem solving, social‐emotional competencies, and math grades. Incremental gains within CSE domains were found after 1 and 2 years of intervention. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 405–417, 2005. 相似文献
