An Empirical Test of Three Instructional Scenarios for Hypervideo Use in a Vocational Education Lesson     

Alberto A. P. Cattaneo  Hans van der Meij  Florinda Sauli 《学校用计算机》2013,30(4):249-267

Recent technological advances are rekindling educational interest in hypervideo (HV). HV provides a good opportunity for enhanced teaching and learning thanks to its affordances for interactivity (advanced navigation control, hyperlinking with supplementary materials, and communication options). This study investigated how these functionalities can be employed in a vocational education context by examining the design of three prototypical HV lesson scenarios (expository, individual learning, and collaborative learning) and comparing their effectiveness with that of a traditional lesson. Effects on motivation and knowledge acquisition were assessed. Results indicated that the HV lessons supported learning more effectively than traditional lessons. On a delayed posttest, all experimental conditions scored significantly higher than the control condition. The special benefits of HV use for expository instruction are singled out for discussion. This study provides an encouraging starting point for scholars who would like to investigate the functional integration of HV in educational practices.  相似文献   

The rhetoric of auscultation: Corporeal sounds,mediated bodies,and abortion rights     

Amanda Nell Edgar 《Quarterly Journal of Speech》2017,103(4):350-371

This essay argues that corporeal sound, including the spoken voice and the auscultated heartbeat, can be understood as material rhetoric, and that material rhetoric, by extension, should be understood as both a force and a networked fluid. I illustrate this argument through the case study of abortion practices and policies, arguing that both mandated heartbeat auscultation and physician speech-and-display provisions represent the forceful fluidity of material rhetoric and demonstrate the power of such rhetoric to carve out networks of meaning. Through this networking, sound’s material role in defining autonomy takes on a powerful role in debates over fetal personhood.  相似文献   

A model for designing hypervideo-based instructional scenarios     

Alberto A. P. Cattaneo  Hans van der Meij  Carmela Aprea  Florinda Sauli  Carmen Zahn 《Interactive Learning Environments》2019,27(4):508-529

In this article, we provide a conceptual model for the design of instructional scenarios integrating hypervideo as an instructional tool. The model provides a structural aid for making design decisions about using hypervideo in instruction. We start by introducing the theoretical rationale for hypervideo as a tool, exploiting three different interactivity functions. We then examine the cognitive and socio-cognitive theories that can inform the design and usage of hypervideo. Next, we present the instantiation of these functions and theories in a software interface, after which we present the model, which is based on the following two layers of design decisions: the first pertains to the interactivity features and the second is connected with the instructional strategy. Three main design steps are presented in the form of guidelines, corresponding to a preparation phase, a production phase, and a use phase. Finally, a set of cases exhibiting exemplary implementations of a hypervideo-based instructional scenario are described.  相似文献   

Development of a competency model and tailored assessment method for high school science teachers utilizing a flipped learning approach

Many professional development programs aim to improve student outcomes by enhancing teacher competencies. Effective evaluation of these programs requires a clear delineation of the competencies to be gained. A competency model was developed to evaluate the impact of a teacher professional program that aimed to improve teachers’ ability to effectively implement technologically engaged modules in a flipped classroom setting. Competencies were identified via participatory evaluation techniques and assessments were aligned to the competencies. The competency of teachers in the knowledge, skills, and abilities needed for creation and delivery of effective flipped lessons can be tracked using a radar graph to guide tailored professional development.

Experimental study on bonding properties between steel strand and concrete at cryogenic temperatures     

谢剑  爱的歌  雷光成  聂治盟 《天津大学学报(英文版)》2016,22(4):308-316

To study the bonding properties between steel strand and concrete at room and cryogenic temperatures, a series of center pullout experiments were conducted on 96 bonding anchorage specimens at the lowest temperature of-165 ℃. The impacts on the bonding property of such parameters as the temperature, concrete strength, the relative concrete cover thickness, and the relative anchorage length were analyzed. The test results indicate that the changes in temperature have a clear effect on the bonding property between steel strand and concrete. As the temperature decreases, the bond stress, which corresponds to a 1 mm slip of steel strand in relation to concrete, and the ultimate bond strength initially increase and subsequently decrease at the inflection point of-80 ℃. The impact of the concrete strength on the bonding property, as shown by the tensile strength and the moisture content interaction, indicates that the bond stress vs concrete strength curve initially increases and later decreases with a decrease in temperature; the bond stress vs concrete cover thickness curve linearly increases, but the bond stress vs anchorage length curve linearly decreases at first and finally levels off.  相似文献

Transitions in Leisure Careers and Their Parallels in Work Careers: The Effect of Constraints on Choice and Action     

Fiona A. E. McQuarrie  Edgar L. Jackson 《Journal of Career Development》2002,29(1):37-53

Careers are increasingly characterized by multiple jobs and employers, and thus the issue of transitions between career components and through career stages is of greater importance than in the past. Transitions have also been extensively studied in the context of serious leisure. This paper uses findings from the literature on serious leisure and leisure constraints to develop propositions about the role of transitions in work careers and the effects that constraints have on transitions.  相似文献
