Effects of Headings on Text Summarization     

Lorch RF  Lorch EP  Ritchey K  McGovern L  Coleman D 《Contemporary educational psychology》2001,26(2):171-191

A summarization task was used to study whether headings influence readers' representations of the topic structure of a text. College students (Experiments 1-3) and sixth- and eighth-graders (Experiment 3) summarized a multiple topic text that (a) included headings introducing every new subtopic, (b) included headings introducing half of the new subtopics, or (c) included no headings. In all experiments, topics were more likely to be included in a summary if they were signaled than if they were not signaled. This effect was magnified when the text was only half signaled: Signaled topics were more likely to appear in a summary if only half the text topics were signaled than if all of the topics were signaled; however, unsignaled topics were less likely to appear in a summary if half of the text topics were signaled than if none of the text topics were signaled. The findings demonstrate that readers rely heavily on headings in a task that emphasizes attention to a text's topic structure. It is suggested that previously observed signaling effects on text recall are mediated by effects on how readers represent a text's topic structure. Copyright 2001 Academic Press.  相似文献

Strengthening Agricultural Education and Training in sub-Saharan Africa from an Innovation Systems Perspective: A Case Study of Mozambique     

Kristin E. Davis  Javier Ekboir  David J. Spielman 《The Journal of Agricultural Education and Extension》2013,19(1):35-51

Abstract

This paper examines how post-secondary agricultural education and training (AET) in sub-Saharan Africa can contribute to agricultural development by strengthening the capacity to innovate—to introduce new products and processes that are socially or economically relevant to smallholder farmers and other agents. Using the AET system in Mozambique as a case study, this paper examines the role of AET within the context of an agricultural innovation system. This innovation systems perspective offers an analytical framework to examine technological change in agriculture as a complex process of interactions among diverse actors who generate, exchange, and use knowledge, conditioned by complex social and economic institutions. The paper argues that while AET is conventionally viewed as key to the development of human capital, it also has a vital role to play in building the capacity of organizations and individuals to transmit and adapt information, products and processes, and new organizational cultures and behaviors. The paper emphasizes the importance of improving AET systems by strengthening the capabilities of organizations and professionals; changing organizational cultures, behaviors, and incentives; and building innovation networks and linkages. The paper offers several recommendations to enhance the effectiveness of AET for agricultural innovation and development. Key reforms include aligning the mandates of AET organizations with national development aspirations; inducing change in the cultures of AET organizations through the introduction of educational programs and linkages beyond the AET system; and enhancing innovative individual and organizational capacity by improving incentives to forge stronger links between AET and other stakeholders.  相似文献   

Hyperbolic discounting of delayed social interaction     

Shawn R. Charlton  Edmund Fantino  Bradley D. Gossett 《Learning & behavior》2013,41(2):159-167

The temporal discounting literature has demonstrated that the loss in value for delayed outcomes is most accurately modeled using a hyperbolic discounting equation. The hyperbolic-shaped function not only describes the shape of discounting for monetary outcomes, but also for other tangibles, such as alcohol, candy, CDs, erotica, cigarettes, cocaine, books, and DVDs. Furthermore, this hyperbolic shape has important theoretical implications. Despite the broad list of outcomes that are hyperbolically discounted, one class of outcomes has only recently received attention: social interactions. For the present study, we used standard binary-choice discounting procedures to explore the function that most accurately describes the change in value of delayed social interactions. The results from the present study suggest that, for 93 participants, the same equations (exponential, hyperbolic, and hyperboloid) used to describe the discounting of nonsocial commodities also describe the relation between delay and the value of social interaction. Similar to previous findings for nonsocial outcomes, the hyperbolic-shaped models provide a fit to the data superior to that of the exponential model.  相似文献

Science Teacher Efficacy and Extrinsic Factors Toward Professional Development Using Video Games in a Design-Based Research Model: The Next Generation of STEM Learning     

Leonard A. Annetta  Wendy M. Frazier  Elizabeth Folta  Shawn Holmes  Richard Lamb  Meng-Tzu Cheng 《Journal of Science Education and Technology》2013,22(1):47-61

Designed-based research principles guided the study of 51 secondary-science teachers in the second year of a 3-year professional development project. The project entailed the creation of student-centered, inquiry-based, science, video games. A professional development model appropriate for infusing innovative technologies into standards-based curricula was employed to determine how science teacher’s attitudes and efficacy where impacted while designing science-based video games. The study’s mixed-method design ascertained teacher efficacy on five factors (General computer use, Science Learning, Inquiry Teaching and Learning, Synchronous chat/text, and Playing Video Games) related to technology and gaming using a web-based survey). Qualitative data in the form of online blog posts was gathered during the project to assist in the triangulation and assessment of teacher efficacy. Data analyses consisted of an Analysis of Variance and serial coding of teacher reflective responses. Results indicated participants who used computers daily have higher efficacy while using inquiry-based teaching methods and science teaching and learning. Additional emergent findings revealed possible motivating factors for efficacy. This professional development project was focused on inquiry as a pedagogical strategy, standard-based science learning as means to develop content knowledge, and creating video games as technological knowledge. The project was consistent with the Technological Pedagogical Content Knowledge (TPCK) framework where overlapping circles of the three components indicates development of an integrated understanding of the suggested relationships. Findings provide suggestions for development of standards-based science education software, its integration into the curriculum and, strategies for implementing technology into teaching practices.  相似文献   

A Longitudinal View of the Liberal Arts Curriculum a Decade After Merger: A Multiple Case Study of Community Colleges in Connecticut,Kentucky, and Louisiana     

Ann Norton  Kristin Wilson 《Community College Journal of Research & Practice》2013,37(7):591-602

This study is an examination of the state of the liberal arts curriculum in community colleges in three geographic regions of the United States. From a constructivist paradigm and using globalization theory as a theoretical framework, this multiple case study examined faculty work life and administrative processes related to curriculum change in merged community and technical colleges. Through an examination of research on globalization, mergers, and trends in the general education and liberal arts curriculum, a gap in the literature emerged in the studies of community college curriculums after merger. This study considers whether the focus on workforce development and decrease in the transfer mission has diminished the liberal arts courses in the college curriculum. Research on liberal arts courses identified them as courses that emphasize higher order thinking and the development of intellectual skills needed to engage in a democratic society. If students are not exposed to these skills, it may have a detrimental effect on a democratic society. Study findings suggested that the English and communication curriculums are narrowing and the mission is more toward workforce skill preparation. Also, the changing demographics of today[#x02019]s community college students, as well as the ongoing budget constraints, create challenges and frustrations for faculty members.  相似文献

Minds Under Siege: Cognitive Signatures of Poverty and Trauma in Refugee and Non-Refugee Adolescents     

Alexandra Chen  Catherine Panter-Brick  Kristin Hadfield  Rana Dajani  Amar Hamoudi  Margaret Sheridan 《Child development》2019,90(6):1856-1865

The impacts of war and displacement on executive function (EF)—what we might call the cognitive signatures of minds under siege—are little known. We surveyed a gender-balanced sample of 12- to 18-year-old Syrian refugees (n = 240) and Jordanian non-refugees (n = 210) living in Jordan. We examined the relative contributions of poverty, trauma exposure, posttraumatic stress, and insecurity to variance in inhibitory control and working memory. We observed associations between poverty and WM, suggesting that, even in populations exposed to substantial violence and fear, poverty is a specific pathway to WM deficit. We did not, however, find associations between EFs and exposures to trauma. Careful distinction between childhood adversities may illuminate which neurocognitive pathways matter for measures of cognitive function.  相似文献
