This is a report on an effort to bring the practices of the Extreme Programming methodology into a Software Design course. Two teams of 11 members followed many of those practices in developing their semester projects. We described the practices required of the development teams, those encouraged, and those that were not easily simulated. Near the end of the semester the students were asked to answer questions about how well each practice had served the process. Summaries and examples of their responses along with the instructor's observations are presented as an evaluation of this approach. The main conclusions are that pair programming is generally powerful and popular, and that it is difficult to make upper level students write tests prior to writing code. Suggestions for what might be done differently to better simulate the Extreme Programming methodology are included. The foremost suggestion is to teach a “test first” approach in all programming courses.  相似文献

ABSTRACT

Although scholarship is important in higher education and faculty productivity expectations are continually increasing, we still do not understand the holistic view of faculty productivity. This study takes a different viewpoint on faculty productivity examining differences by university classification and by discipline. Most importantly, we sought to obtain the effects of the delivery mode of terminal degree on later faculty productivity. The mode of terminal degree via Internet delivery looks attractive to students, but this study found that this has implications for future research productivity. These three elements illustrate a different scope that has important implications for administrative leaders looking to hire future faculty as well as students thinking about becoming a future faculty member. To capture this view, 600 faculty members from 59 American universities were surveyed. From this survey, five different variables emerged to create an overall faculty scholarly productivity factor. This factor was then compared against university classification, discipline, and mode of terminal degree. Results showed surprising significant differences between university classifications and disciplines as compared to scholarly productivity. One of the most noteworthy findings was that there is a significant difference in faculty productivity based on the mode of terminal degree. Furthermore, no difference in later faculty scholarly productivity exists between that of a hybridized, online degree and a purely online degree. Again, these results indicate significant finds which have a high influence on faculty scholarly productivity, which holds important implications for the future of the university.  相似文献   

Extended sociometric status of adolescents with mild handicaps: A cross‐categorical perspective     

Edward J. Sabornie  James M. Kauffman  Douglas A. Cullinan 《Exceptionality》2013,21(3):197-209

Abstract

We compared adolescents identified as having mild mental retardation, learning disabilities, behavioral disorders, and no known handicaps on regular classroom sociometric status extended to include measures of social impact and social preference. Students attended regular classroom physical education classes in six high schools from two adjacent school districts. We administered a rating scale sociometric in physical education classes where students with mild handicaps were enrolled. Results indicated that not all students with mild handicaps were similar in social acceptance, rejection, and preference. Students with mild handicaps also differed in composition of subgroups labeled popular, rejected, neglected, controversial, and average. We discuss implications concerning social standing differences across types of mild handicaps and the value of examining sociometric status in the manner employed here.  相似文献   

Supporting Educators to Implement Mand Training for a Student with Multiple Disabilities     

Virginia L. Walker  Stephanie N. DeSpain  James R. Thompson 《Exceptionality》2013,21(4):262-277

ABSTRACT

The purposes of the study were to assess the effects of an online learning module on the implementation of mand training by a classroom team and determine whether training improved manding for a student with multiple disabilities. The classroom team utilized the Support Needs Assessment and Planning (SNAP) process to identify supports and guide implementation of the mand training procedures. The results indicate that both the special education teacher and paraprofessional were able to implement the mand training strategy with fidelity after completing the online module and student manding increased. The classroom team reported that both the online learning module and SNAP process were valuable for planning and implementing research-based supports. Limitations, implications for practice, and future research considerations are addressed.  相似文献   

A comparison of year 1 and year 6 students' conceptions of evaporation and condensation: dimensions of conceptual progression     

Russell Tytler 《International Journal of Science Education》2013,35(5):447-467

A range of challenging activities centred on evaporation and condensation were explored with year 1 and year 6 children. Their explanations in group discussion, written responses and interview were analysed, using NUD*IST qualitative analysis software, to explore the nature and coherence of their conceptions. The data was used to critically evaluate previous claims in the literature concerning the characteristics of progression in understanding of evaporation, and to identify the main dimensions that characterize the differences in children's explanations. The older children displayed a surer sense of ontological categories, greater epistemological sophistication including their ability to link explanations and evidence, greater precision in the use of conceptual language, and a greater range of associations they could make.  相似文献   

Learning Visualization Strategies: A qualitative investigation     

Daniel Halpern  Kyong Eun Oh  Marilyn Tremaine  James Chiang  Karen Bemis  Deborah Silver 《International Journal of Science Education》2013,35(18):3038-3065

The following study investigates the range of strategies individuals develop to infer and interpret cross-sections of three-dimensional objects. We focus on the identification of mental representations and problem-solving processes made by 11 individuals with the goal of building training applications that integrate the strategies developed by the participants in our study. Our results suggest that although spatial transformation and perspective-taking techniques are useful for visualizing cross-section problems, these visual processes are augmented by analytical thinking. Further, our study shows that participants employ general analytic strategies for extended periods which evolve through practice into a set of progressively more expert strategies. Theoretical implications are discussed and five main findings are recommended for integration into the design of education software that facilitates visual learning and comprehension.  相似文献   

Researching learning outcomes: building confidence in our conclusions     

Mary James  Andrew Pollard  Gareth Rees  Chris Taylor 《Curriculum Journal》2013,24(1):109-122

The ESRC Teaching and Learning Research Programme is expected to produce knowledge of high social scientific quality and practical pedagogic value. It faces, in a particularly acute form, the issue of how confidence in its conclusions can be built. This article begins with some conceptual clarification of the notion of a ‘warrant’ for research findings and distinguishes between warrants in social research and warrants for educational policy and practice. It then, in the specific context of research on learning outcomes, proposes an integrated model that recognizes the importance of, and relationships among, criteria associated with research design and empirical work, theoretical coherence, relationship with other research, and user affirmation. It concludes by emphasizing the need for continuing debate about, and development of, the roles and relationships of ‘researchers’ and ‘users’.  相似文献   

Editorial     

Mary James 《Curriculum Journal》2013,24(1):3-6

In earlier papers, we considered some of the pedagogy and assessment practices enacted by physical education (PE) teachers, when attempting to translate a centrally prescribed rationale into meaningful performance-led teaching within an integrated curriculum—Higher Still Physical Education (HSPE) in Scotland. One recurring theme from the data collected was anecdotal assertions from teachers that students were disadvantaged from achieving high levels of authentic attainment by written assessment instruments. Accordingly, students completed oral assessments, which were subsequently transcribed and marked to the same criteria as their written examination answers. However, results indicated that students were not disadvantaged as claimed. On the contrary, results highlighted that to various extents weaknesses in content knowledge were partially concealed through holistic written assessment. More optimistically, findings indicated that oral interviews could provide a constructive atmosphere for ongoing assessment, as well as providing informative feedback for teachers to utilize as part of their reflections on practice. Evidence from Senior Level Physical Education (SLPE) in Australia highlights the importance of language in dialogue and discussion within integrated teaching, learning and assessment environments. Consequently, a wider review of the functions such awards might play in students' school experiences prior to higher education appears merited.  相似文献   

A bibliometric analysis of academic publication and NIH funding     

Jiansheng Yang  Michael W. Vannier  Fang Wang  Yan Deng  Fengrong Ou  James Bennett  Yang Liu  Ge Wang 《Journal of Informetrics》2013,7(2):318-324

Academic productivity and research funding have been hot topics in biomedical research. While publications and their citations are popular indicators of academic productivity, there has been no rigorous way to quantify co-authors’ relative contributions. This has seriously compromised quantitative studies on the relationship between academic productivity and research funding. Here we apply an axiomatic approach and associated bibliometric measures to revisit a recent study by Ginther et al. (Ginther et al., 2011a, Ginther et al., 2011b) in which the probability of receiving a U.S. National Institutes of Health (NIH) R01 award was analyzed with respect to the applicant's race/ethnicity. Our results provide new insight and suggest that there is no significant racial bias in the NIH review process, in contrast to the conclusion from the study by D. K. Ginther et al. Our axiomatic approach has a potential to be widely used for scientific assessment and management.  相似文献   

Attitudes about publishing and normal science advancement     

Christopher McCarty  James W. Jawitz 《Journal of Informetrics》2013,7(4):850-858

The objective of this work was to examine the relationship between attitudes about publishing across disciplines and the scientific impact of authors. We conducted a web survey of 1066 authors randomly selected from four disciplines in the Web of Knowledge: economics, anthropology, water resources and biochemistry (approximately 250 from each discipline). Authors were asked questions about publishing norms within their discipline. The h-index of authors was subsequently calculated from data available from the Web of Knowledge. Authors in biochemistry had on average twice the h-index of those in economics, anthropology and water resources. Biochemists had higher expectations about the number of articles published for hire and promotion, more strongly valued interdisciplinary publishing, felt the cutting edge of their science was clearer, and had more defined patterns of author credit assignment than the other disciplines. Anthropologists exhibited a lower relationship between h-index and the number of years since their first publication. We conclude that attitudinal differences between disciplines may lead to differences in the recognition of scientific findings and the therefore the establishment of normal science.  相似文献
