Tools for automatic grading programming assignments, also known as Online Judges, have been widely used to support computer science (CS) courses. Nevertheless, few studies have used these tools to acquire and analyse interaction data to better understand the students’ performance and behaviours, often due to data availability or inadequate granularity. To address this problem, we propose an Online Judge called CodeBench, which allows for fine-grained data collection of student interactions, at the level of, eg, keystrokes, number of submissions, and grades. We deployed CodeBench for 3 years (2016–18) and collected data from 2058 students from 16 introductory computer science (CS1) courses, on which we have carried out fine-grained learning analytics, towards early detection of effective/ineffective behaviours regarding learning CS concepts. Results extract clear behavioural classes of CS1 students, significantly differentiated both semantically and statistically, enabling us to better explain how student behaviours during programming have influenced learning outcomes. Finally, we also identify behaviours that can guide novice students to improve their learning performance, which can be used for interventions. We believe this work is a step forward towards enhancing Online Judges and helping teachers and students improve their CS1 teaching/learning practices. 相似文献

Intellectual Property Rights (IPRs) are widely acknowledged to be of central importance to research universities worldwide. This article assesses the patent portfolio of Universidade Federal Fluminense (UFF), which is located in State of Rio de Janeiro in Brazil and currently consists of the largest Brazilian research university in terms of the total number of enrolled undergraduate students. More specifically, this study provides robust empirical evidence pointing out that a major university in a developing country is strengthening its patent portfolio by increasing the number of patent applications. In addition, it was also possible to observe that UFF's patent portfolio is dominated by emerging technologies addressing human necessities, such as medical, hygiene, or veterinary products. 相似文献

A Sixty Year History and Analysis of the Japanese Publishing Industry: A Statistical Analysis of Circulation 总被引：1，自引：0，他引：1
The purpose of this paper is to investigate how changes in the social environment of print media have affected the history
of the Japanese publishing industry in the postwar period. Data on the circulation of books, magazines, and newspapers are
analysed on a population basis. The results of these analyses show that per-capita circulation of these media increased almost
monotonically until the 1980s, but then began to decrease after peaking in the 1990s. After conducting statistical correlation
analyses, we conclude that per-capita circulation was affected by economic trends indicated by the GDP growth rate. Our analyses
also show a positive correlation between the pace of change in per-capita book and magazine circulation, and this reciprocal
relationship is investigated in detail. 相似文献

In this study we compared the kinematic features of the throwing motion between young baseball players of different age groups. Forty-four Japanese baseball players aged 6.1 to 12.3 years who regularly played baseball, including pitchers and position players, had their throwing actions analyzed three-dimensionally using high speed videography. Of this sample, 26 players aged above 9 years of age were categorized as the senior group, while the remaining 18 were categorized as the junior group. Senior group throwers had greater height and body mass, and produced a greater ball speed than junior group throwers. The throwing arm movement of senior group throwers was similar to that of adult skilled players. However, in the junior group throwers, the shoulder horizontal adduction angle was larger during the arm acceleration phase, and the maximum angular velocities of elbow extension and shoulder internal rotation occurred later than in senior group throwers. These results indicate that players aged above 9 years can acquire a mature throwing arm movement, while players younger than that will use an immature motion. A possible reason why these differences were shown is that the official baseball is relatively heavy for junior group throwers; they would be better advised to use a lighter ball in throwing practice. 相似文献
