重点学科评估的概化分析

选取3位有经验的评估专家,对河北省8个重点学科的自评量表进行评价,使用概化理论中的混合设计模型,对该评价结果所反映的量表结构及方差误差进行分析。结果表明,不同的评估专家对学科能力的评价并没有造成很大的系统误差,而学科、指标、评估专家的交互作用,以及指标和评估专家的交互作用方差很大,说明评估体系的二级指标设置尚存在较大缺陷。     

Decoding Reed-Solomon codes using Euclid’s algorithm

Reed-Solomon codes are indeed an elegant illustration of a very practical application of abstract algebra. An interesting discovery was the fact that Euclid’s algorithm for finding greatest common divisors of polynomials, could be used for decoding these codes. In this article we explain this connection. Priti Shankar is with the Department of Computer Science and Automation at the Indian Institute of Science, Bangalore. Her interests are in theoretical computer science and error correcting codes.     

Does the private sector expand access to higher education? A cross-national analysis, 1999-2017

This article examines the relationship between the private share of tertiary enrollments and overall access, measured by the gross tertiary enrollment rate, using a cross-national dataset from 122 countries spanning 1999−2017. In contrast to the dominant assumption in international development that expanding the private sector will necessarily increase access, we find a weak association between the private share of tertiary enrollments and gross tertiary enrollment ratio globally. That said, this association is stronger when there is high demand for higher education, as proxied by secondary gross enrollment ratio and urbanization. We also find regional variation, with private higher education positively associated with access in Central and Eastern Europe and core English-speaking countries and negatively associated with access in sub-Saharan Africa, after accounting for demand factors. We argue that private higher education is only an effective policy solution for expanding access when there is high unmet demand for higher education and a conducive policy context.

Analysis and application of error concealment tools in AVS-M decoder

Audio Video coding Standard (AVS) is the latest audio and video coding standard of China. AVS Part 7 (also known as A VS-M) targets mobility applications where error concealment is of great importance. This paper first briefly introduces the general concept of error concealment. Then two error concealment schemes are proposed and implemented on AVS-M decoder under different test conditions. Simulation results of the schemes and suggestions on how to use these tools are also provided.     

Affective-motivational effects of performance feedback in computer-based assessment: Does error message complexity matter?

The impact of computer-based performance feedback on students’ affective-motivational state may be very different, depending on the positive or negative direction of the feedback message and its specific content. This experiment investigated whether more elaborated error messages improve students’ affective-motivational response to negative (i.e., corrective) feedback. We systematically varied the presence and complexity of corrective feedback messages (1 × 4 between-subjects design) and analyzed the effects of the provided feedback on students’ emotions, task-related perceived usefulness, and expectancy-value beliefs. University students (N = 439) worked on a low-stakes test with 12 constructed-response geometry tasks. They received either no feedback or different complexities of immediate corrective feedback after incorrect responses (i.e., Knowledge of Results [KR], Knowledge of Correct Response [KCR], or Elaborated Feedback [EF]), paired with immediate confirmatory KCR feedback after correct responses (i.e., confirming their response). Our data showed that students’ task-level performance moderated the emotional impact of feedback (i.e., beneficial effects after correct responses; detrimental effects after incorrect responses). Students’ performance further moderated several feedback effects on students’ expectancy-value beliefs. Regarding error message complexity, we found that students reported higher levels of positive emotions after receiving EF or KCR compared to KR, while only EF decreased students' level of negative emotions compared to KR and increased students' task-related perceived usefulness compared to all other groups. Overall, our results suggest that performance feedback is likely to improve students’ affective-motivational state when the feedback confirms a correct response. Moreover, when reporting an error, EF (or KCR messages) were more beneficial to affective-motivational outcomes than simple KR notifications.     

错误分析及其在外语教学中的意义

与对比分析不同，错误分析从认知心理学的角度对待学习者在学习过程中所犯的错误，使人们认识到错误是学习过程中所不可避免的，说明学习者逐渐形成自己的规则。因此，对错误进行分析，探究其成因，对外语教学具有重要意义。
