Online interaction across three contexts: an analysis of culture and technological affordances     

Todd L. Sandel  Richard Buttny  Mary Varghese 《Journal of Intercultural Communication Research》2019,48(1):52-71

Students were linked virtually across three contexts: U.S., Malaysia, and China. Differences emerged in how student-created messages were constructed and interpreted; these impacted perceived relational affiliation. Messages constructed by students in Malaysia and China exhibited casual talk, greater self-disclosure, requests for personal information, and greater use of emoticons/emoji. Interactions were perceived as informal, friendly, and positive. U.S. students’ messages often showed institutional talk, less self-disclosure, and more attention to the instructor-assigned task. Asian-U.S. student pairs perceived their interactions as formal, less friendly, and less positive. This study shows how online technologies may be afforded and shaped by culture and interaction.  相似文献

Jennifer Leffler  Jessica Hayden  Todd Enoch 《期刊图书馆员》2017,72(1-4):102-104

ABSTRACT

The University of Northern Colorado (UNC) Libraries have experienced a surge in streaming video requests in the past few years. Like others, UNC’s Technical Services department has found new ways to manage procedures and workflows associated with this format. This session covered the experiences and strategies of the presenters for handling streaming video databases, licensed content ripped from DVD, firm orders, and multiyear streaming licenses.  相似文献   

Potentiation of responding on a VR schedule by a stimulus correlated with reinforcement: Effects of diffuse and localized signals     

Phil Reed  Todd R. Schachtman  Geoffrey Hall 《Learning & behavior》1988,16(1):75-82

In Experiment 1, rats were trained to leverpress on a variable ratio (VR) 30 schedule with a 500-msec delay between the reinforced response and food delivery. Subjects that experienced a signal during the delay responded faster than did control subjects that received the stimulus un-correlated with reinforcement. Higher response rates were obtained when the stimulus used to signal reinforcement was auditory rather than visual. Experiments 2 and 3 compared the effects of signaling reinforcement with either a localized or a diffuse light on responding maintained by VR schedules of reinforcement. Elevated response rates were observed with the diffuse stimulus, but the localized stimulus failed to produce such potentiation. Experiment 3 also examined the conditioned reinforcing power of localized and diffuse visual stimuli. These results are discussed with reference to (1) theories of selective association and sign tracking and (2) their implications for current theories of signaling reinforcement.  相似文献   

Should the Simple View of Reading Include a Fluency Component?     

Suzanne M. Adlof  Hugh W. Catts  Todd D. Little 《Reading and writing》2006,19(9):933-958

The Simple View of Reading states that reading comprehension is the product of word recognition and listening comprehension. Whereas much research has focused on word recognition accuracy, recent attention has been directed toward word recognition fluency. The current study investigated whether a separate fluency component should be added to the Simple View of Reading. A battery of reading and language measures was administered to 604 children in second, fourth, and eighth grades. Approximately half these children had language and/or nonverbal cognitive impairments in kindergarten, but weighting procedures were used to reduce the potential bias this sampling characteristic may have entailed. Structural equation modeling was used to determine whether fluency accounted for unique variance in reading comprehension after controlling for word recognition accuracy and listening comprehension. Individual profile analyses were conducted to determine the number of individual participants who␣had poor fluency in the spite of good word recognition accuracy and listening comprehension. Results showed that fluency did not account for unique variance in reading␣comprehension and that few individuals had problems in fluency separate from word recognition accuracy or listening comprehension. Thus, it does not appear that a separate fluency component should be added to the Simple View of Reading.  相似文献   

Going to Prison: The Effect of a Prison Tour on Students’ Attitudes Toward Punitiveness     

Wendy R. Calaway  Todd Callais  Robin Lightner 《Journal of Criminal Justice Education》2016,27(3):432-448

The pedagogical approaches of a criminal justice education affect the attitudes and perceptions of those most likely to develop and administer criminal justice policies in the future. This study examines the effect of a prison tour on students’ understanding of prison and attitudes about punishment. Undergraduate criminal justice students were given a survey to assess their attitudes about prisons, prisoners, and alternative sanctions before and after a field trip to the Southern Ohio Correctional Facility. Post-survey responses showed changes in students’ perceptions regarding punitiveness, prisons, prisoners, and rehabilitation. We discuss this finding within the framework of the contact hypothesis, and we recommend including this type of first-hand exposure as part of a criminal justice curriculum.  相似文献   

Visual Learning and the Brain: Implications for Dyslexia     

Matthew H. Schneps  L. Todd Rose  Kurt W. Fischer 《Mind, Brain, and Education》2007,1(3):128-139

ABSTRACT— The central and peripheral visual fields are structurally segregated in the brain and are differentiated by their anatomical and functional characteristics. While the central field appears well suited for tasks such as visual search, the periphery is optimized for rapid processing over broad regions. People vary in their abilities to make use of information in the center versus the periphery, and we propose that this bias leads to a trade-off between abilities for sequential search versus contemporaneous comparisons. The parameter of periphery-to-center ratio (PCR) describes the degree of peripheral bias, which evidence suggests is high in many people with dyslexia. That is, many dyslexics favor the peripheral visual field over the center, which results in not only search deficits but also (more surprisingly) talents for visual comparison. The PCR framework offers a coherent explanation for these seemingly contradictory observations of both deficit and talent in visual processing. The framework has potential implications for instructional support in visually intensive domains such as science and mathematics.  相似文献

Using Markov Chain Analyses in Counselor Education Research     

David K. Duys  Todd C. Headrick 《Counselor Education & Supervision》2004,44(2):108-120

This study examined the efficacy of an infrequently used statistical analysis in counselor education research. A Markov chain analysis was used to examine hypothesized differences between students' use of counseling skills in an introductory course. Thirty graduate students participated in the study. Independent raters identified the microskills students used and the effectiveness of participants' counseling sessions. Significant differences were found in the counseling processes of students who were rated as effective and ineffective using a Markov chain analysis. Implications for future research using Markovian analyses in counselor education research are explored.  相似文献   

Lesbian,gay, bisexual,and transgender college students with disabilities: A look at multiple cultural minorities     

Debra A. Harley  Theresa M. Nowak  Linda J. Gassaway  Todd A. Savage 《Psychology in the schools》2002,39(5):525-538

College students with disabilities who are lesbian, gay, bisexual, or transgender (LGBT) represent diverse cultural minorities with multiple service needs involving disabilities, identities, and adjustment strategies. These students are usually accommodated in the college environment because of their disability while simultaneously marginalized based on their sexual orientation. This article discusses LGBT college students with disabilities as multiple cultural minorities with a focus on educational environments, institutional issues, and strategies for university personnel. © 2002 Wiley Periodicals, Inc.  相似文献   

Multimedia tools for use in materials handling classes     

Sunderesh S. Heragu  Robert J. Graves  Charles J. Malmborg  Sybillyn Jennings  Dianna L. Newman 《European Journal of Engineering Education》2003,28(3):375-393

Materials handling is a vital function in a manufacturing or distribution system. Efficient handling of material allows such systems to operate at high levels of productivity. US companies invest over US$60 billion annually in materials handling technology. It is therefore extremely important for universities to prepare materials handling engineers who understand the principles of materials handling, as well as the design, implementation, operation and control of materials handling systems so that they can ensure the cost-effectiveness of this investment. This paper pertains to development of an interactive, multimedia-based system for use in materials handling classes. Modules in the system introduce students to: the 10 principles of materials handling; and two major equipment categories—conveyors and automated storage and retrieval systems. They illustrate industrial applications of material handling equipment and teach the problem-solving process through a case study and an extensive series of models, algorithms, problems and solutions. The modules have been formally evaluated and results are summarized. They are being distributed at a nominal cost to US and international universities. The module described in this paper on the ‘10 principles of materials handling’ was selected as a finalist for the 2002 PREMIER Award for Excellence in Engineering Education Courseware.  相似文献
