Beyond Heroes and Villains: Examining Explanatory Mechanisms Underlying Moral Disengagement     

Meghan S. Sanders  Mina Tsay-Vogel 《Mass Communication and Society》2016,19(3):230-252

In recent years, theorizing regarding the role and importance of media entertainment in everyday life has garnered much serious attention by media effects scholars. The role of moral judgments, sanctions, and lack thereof are areas in which theoretical development has expanded. The present study examines narrative exposure, identification, and moral judgment as indicators of the degree to which individuals may morally disengage during mediated entertainment experiences. In addition, this study attempts to further expand disposition theory and theorizing about the role of moral disengagement by moving beyond conceptualizations of good, bad, and morally ambiguous characters to explore more subtle moral distinctions between characters as they exist within the same narrative and along a continuum. Results suggest that identification and moral judgment serve as important mediators predicting moral disengagement; however, the nature of these relationships are moderated by the perception of the character’s moral fortitude.  相似文献   

Secondary science teachers' knowledge base when teaching science courses in and out of their area of certification     

Linda R. Sanders  Hilda Borko  J. David Lockard 《科学教学研究杂志》1993,30(7):723-736

This study examined the similarities and differences in experienced secondary science teachers' planning, teaching, and reflecting on their teaching, when teaching in their science area of certification and when teaching in another science area. The study also focused on the influence of these teachers' content knowledge, pedagogical knowledge, and pedagogical content knowledge on their planning, teaching, and reflecting. Experienced teachers were observed and interviewed while teaching classes in their science area of certification, and in another science area they were teaching for the first or second time. Both similarities and differences in teaching were found in the two areas for all three teachers. For example, their planning and postlesson reflections were similar in both areas. In the interactive phase of teaching more differences were observed. Many aspects of their teaching resembled that of expert teachers in other studies. In the unfamiliar science area, the teachers sometimes acted like novice teachers. However, they were able to draw upon their pedagogical knowledge to provide a framework for their teaching in both science areas. Their wealth of pedagogical knowledge, and pedagogical content knowledge for general science topics, seemed to sustain them in whatever content they were teaching. Recommendations for further study and implications for teacher education are discussed.  相似文献   

Extreme Programming: The Student View     

Dean Sanders 《Computer Science Education》2013,23(3):235-250

Students in two offerings of a software engineering course were asked to write opinion papers regarding the use of Extreme Programming (XP) in an undergraduate computer science curriculum. The majority opposed the use of XP as the preferred life-cycle model for the project in that course, but they did support introducing some of the practices of XP in selected courses. They felt that unit testing and coding standards should become part of the introductory programming courses, but other practices should be deferred to specific project-oriented courses, or not introduced at all. Two pilot studies provided additional insights that are consistent with the students' opinions.  相似文献   

Two- and Three-Year Achievement Results From the Memphis Restructuring Initiative     

Steven M. Ross  William L. Sanders  S. Paul Wright  Sam Stringfield  L. Weiping Wang  Marty Alberg 《School Effectiveness & School Improvement》2013,24(3):323-346

The purpose of this study was to analyze student achievement data from the first 3 years of the Memphis Restructuring Initiative (MRI). The MRI represents one of the first efforts by an urban school district to move past traditional top-down versus bottom-up reform debates by providing systemic support for outside-in/inside-out implementation and local co-construction of externally-developed reform designs in schools. Analyses of academic achievement focus on a state-of-the-art measure of value added assessments. At the end of 3 years the reforming schools had produced generally positive gains relative to locally matched control schools. Those results varied somewhat by reform type and by level of poverty in the communities being served. Based on the research methods used and the results, implications for future research and practice in educational reform are discussed.  相似文献   

Small Robot Projects: Before You Start     

Robert McCartney  Kathryn E. Sanders 《Computer Science Education》2013,23(1):56-63

Working with robots is an attractive possibility for educators at many levels. The price and availability of robotic hardware are favorable, there are often examples in the media of school groups doing robotic projects, and the projects support group design and co-operative activity. Still, these projects cannot be organized without considerable effort. In this article, we look at some of the opportunities and pitfalls that are encountered when working with robots in an educational setting, illustrating them with anecdotes from our experience with eight small robot-building projects, with participants ranging in age from nine to adult, and duration ranging from a single day to a full semester. We suggest some of the benefits of these projects and outline the problems organizers and participants will be likely to face.  相似文献   

Technique and timing in women's inward two and one half somersault tuck (405C) and the men's inward two and one half somersault pike (405B) 3 m springboard dives     

Sanders R  Burnett A 《Sports biomechanics / International Society of Biomechanics in Sports》2003,2(2):251-265

The purpose of this study was to compare the inward two and one half somersault dive in a tuck position (405C) performed by females (n = 22) and the inward two and one half somersault dive in a pike position (405B) performed by males (n = 24) to determine changes required by females to successfully perform 405B. Key performance variables in inward dives were also compared to those of backward dives. Video data of the dives performed at the 1999 FINA World Diving Cup were captured and digitized to obtain times and postures of the divers at specific events including takeoff and entry. Estimates of flight height and mass-normalised work done on the springboard were obtained from flight times. Some females worked the springboard strongly enough to generate sufficient height and rotation to perform 405B. Males performed 405B comfortably because they achieved better height and rotation than the females. A comparison of backward and inward dives revealed that divers are able to attain greater height in backward dives than inward dives.  相似文献   

The effect of periodized resistance training on accelerative sprint performance     

Moir G  Sanders R  Button C  Glaister M 《Sports biomechanics / International Society of Biomechanics in Sports》2007,6(3):285-300

The purpose of this study was to assess the effect of periodized resistance training on accelerative sprint performance. Sixteen physically active men participated in a randomized controlled study. An experimental group (n = 10) completed an 8-week periodized resistance training intervention, while a control group (n = 6) did not train. Pre- and post-training measures of 20-m straight-line sprint time, including a 10-m split, maximum strength, and explosive strength, were recorded. Flight time, stance time, stride length, and stride frequency were quantified from digitized video recordings of the first three strides of the 20-m sprint. Resistance training resulted in significant increases in maximum strength (parallel back squat: 19%) and explosive strength (6-10%). However, both groups increased 0-10 m sprint times (experimental group = 6%; control group = 3%) while 10-20m times were reduced (experimental group = 7%; control group = 4%), highlighting the mechanical differences between the distinct sprint phases. The change during the 0-10m interval was accompanied by a reduction in stride frequency during the first three strides. Strength coaches should be aware that the potential benefits of increased muscular strength during short sprints are likely to be affected by mechanical specificity and that improvements in sprinting performance may not occur immediately after a period of resistance training.  相似文献   

John A. Stormer and the Hofstadter hypothesis     

Keith R. Sanders  Robert P. Newman 《Communication Studies》2013,64(4):218-227

Does political rhetoric hold the key to an understanding of political pathology? Blending historical scholarship and behavioral research, this study tested empirically hypotheses derived from Richard Hofstadter's model of the “paranoid style” in American politics. The data were drawn from John A. Stormer's None Dare Call It Treason.  相似文献   

Students selling sex: marketisation,higher education and consumption     

Teela Sanders  Kate Hardy 《British Journal of Sociology of Education》2015,36(5):747-765

Robust academic research on the topic of students involved in the sex industry is in its infancy, yet the relationship appears consistent and permanent. This paper draws on findings from the largest study into the stripping industry in the United Kingdom to explore the relationships between students, sex work and consumption. To make sense of the relationship between students and participation in the sex industry, a deeper understanding of other social and cultural processes is needed. In this discussion we argue that the following points are relevant and interlinked: changes to the nature of sexual commerce and sexual consumption as they become part of the marketplace; changes in social attitudes and the rise of ‘respectability’ in sexual commerce; the ‘pleasure dynamic’ amongst students; and changes in the higher education structure that place students as consumers as well as financially fragile. We set out a future research agenda given that this relationship is set to grow as the individual bares the cost of higher education.  相似文献
