What are Middle School Students Talking About During Clicker Questions? Characterizing Small-Group Conversations Mediated by Classroom Response Systems     

Lauren A. Barth-Cohen  Michelle K. Smith  Daniel K. Capps  Justin D. Lewin  Jonathan T. Shemwell  MacKenzie R. Stetzer 《Journal of Science Education and Technology》2016,25(1):50-61

There is a growing interest in using classroom response systems or clickers in science classrooms at both the university and K-12 levels. Typically, when instructors use this technology, students are asked to answer and discuss clicker questions with their peers. The existing literature on using clickers at the K-12 level has largely focused on the efficacy of clicker implementation, with few studies investigating collaboration and discourse among students. To expand on this work, we investigated the question: Does clicker use promote productive peer discussion among middle school science students? Specifically, we collected data from middle school students in a physical science course. Students were asked to answer a clicker question individually, discuss the question with their peers, answer the same question again, and then subsequently answer a new matched-pair question individually. We audio recorded the peer conversations to characterize the nature of the student discourse. To analyze these conversations, we used a grounded analysis approach and drew on literature about collaborative knowledge co-construction. The analysis of the conversations revealed that middle school students talked about science content and collaboratively discussed ideas. Furthermore, the majority of conversations, both ones that positively and negatively impacted student performance, contained evidence of collaborative knowledge co-construction.  相似文献   

Adaptive progressive download based on the MPEG-4 file format     

Färber Nikolaus  Döhla Stefan  Issing Jochen 《浙江大学学报(A卷英文版)》2006,7(1):106-111

In this paper we describe how progressive download and adaptive streaming can be combined into a simple and efficient streaming framework. Based on the MPEG-4 file format (MP4) we use HTTP for transport and argue that these two components are sufficient for specifying an open streaming architecture. The client selects appropriate chunks from the MP4 file to be transferred based on (1) the header information (i.e. the “moov” box) in the first part of the file and (2) his observation of network throughput. The framework is completely client driven which allows for better server scalability and reduces signalling overhead. We discuss architecture and implementation issues such as complexity, interoperability and scalability and compare to 3GPP PSS Rel-6 adaptive streaming when appropriate. Measurements from a simple MP4/HTTP streaming client are presented showing that appropriate chunks are selected such that increased reliability is achieved.  相似文献

Faculty members' provision of instructional accommodations to students with LD     

Bourke AB  Strehorn KC  Silver P 《Journal of learning disabilities》2000,33(1):26-32

The existing research on the instructional accommodation process of college students with learning disabilities focuses on attitudes and theoretical models without delineating actual practices. To date, the discussion of facilitating factors and barriers to this process has been broad and lacking specificity. Surveys were mailed to 485 faculty members at the University of Massachusetts, Amherst, who received an instructional accommodation form from the office of Learning Disabilities Support Services in the fall of 1995. The survey focused on faculty members' reported degree of ease or difficulty in implementing instructional accommodations, their perceptions regarding adequacy of support, and their own beliefs and understandings concerning the need for and benefit of providing instructional accommodations. The results indicate that beliefs about the helpfulness of and need for instructional accommodations were associated with the provision of the accommodations. Also, a perception of support from the University influenced the ease of providing instructional accommodations. A significant difference was found between the behavior of tenure-track faculty and non-tenure-track faculty.  相似文献

Attitudes toward the level of men's involvement in abortion decisions     

Nelson ES  Coleman PK  Swager MJ 《The Journal of humanistic education and development》1997,35(4):217-224

College students completed a questionnaire that assessed their attitudes toward the level of male responsibility in abortion decisions. Overall, both men and women thought that men should have some degree of involvement in the abortion decision. However, as expected by the first hypothesis, men indicated a desire for more responsibility in the abortion decision than women thought the men should have. A second hypothesis predicted women would feel more strongly than men that abortion was strictly a woman's issue. Contrary to the hypothesis, women tended to disagree that abortion was strictly a women's issue. Implications of the findings are discussed.  相似文献   

The Relative Efficiency of Departments at a Turkish Engineering College: A Data Envelopment Analysis     

Gülser Köksal  Burak Nalçaci 《Higher Education》2006,51(2):173-189

In this study, Data Envelopment Analysis is used to measure relative efficiencies of academic departments of an engineering college. Input and output criteria are determined and measured utilizing the academic personnel performance measurement scheme of the College. New measures are developed to compare departments of different disciplines. The discriminating power of the measurement models is improved by restricting criteria weights directly and by using a multiple criteria decision making approach. Sensitivity of the results to exclusion of a criterion and changes in relative importance of the criteria is analyzed. Evaluation of the results jointly by the college administration and the departments is explained for a successful efficiency improvement mechanism.  相似文献
