The Teacher Behavior Inventory: validation of teacher behavior in an interactive lecture environment

Students’ rating of teacher behaviors provides valuable information on teaching improvement and instructional quality. Unfortunately, there is a lack of new validated instruments for measuring teacher behaviors. The Teacher Behaviors Inventory is an old inventory that was initially developed to measure teaching behaviors as regards lecture-based instructions, which is effected through the use of low-inference items. The aim of this study was to assess its continued suitability in the present educational setting by examining its construct validity and internal consistency through the lens of one lecturer’s teaching behaviors, as rated by 527 students after six interactive lectures. The variables evaluated, as mentioned above, were achieved after an items removal process, which resulted in a 32-item version. Apart from being valid and reliable, this condensed version allows for immediate assessment of teaching behaviors after an instruction session as the rating procedure is now more straightforward and less time-consuming, and also enables a reduction in rating errors. Therefore, the 32-item format serves as a practical diagnostic feedback tool in the present educational arena, permitting a longitudinal teaching behavior assessment to enhance teachers’ professional development.

从语言测试学角度试析改革后的CET考试

大学英语考试是全国性的用于评估和指导大学英语教学的标准相关常模参照性考试。它对英语的教与学既有积极的促进作用,也有着严重的负面影响。改革后的CET考试在效度、信度、难度以及可操作性上仍然存在着不可忽视的问题。CET考试不仅应信度、效度并重,还应注重考试的可操作性。此外,CET考试中,应该增设口语考试的内容,尽量做到听说读写译加权相当。     

内疚的界定和测量以及研究方法述评

作为人类高度社会化的负性自我道德情感体验,内疚是个体对自身经历的不良事件进行评价和认知的产物,同时也是影响个体后续行为的重要因素,它与个体的身心健康和社会化的发展有着非常密切的关系。西方心理学界对这一情绪进行了大量的研究。国内关于内疚的研究报告零星可数。对内疚的概念界定与测量、内疚态度的研究现状进行系统的阐述,有助于深入探讨内疚领域特有的问题。     

Using students’ feedback for teacher education: measurement invariance across pre-service teacher-rated and student-rated aspects of quality of teaching

Comparing self-perceived quality of teaching to students’ perception can be used in higher education to improve the quality of teaching of pre-service teachers in teacher education. However, comparing these measurements from different perspectives is only meaningful if the same constructs are being measured. To shed light on this comparison’s meaningfulness, we scrutinised whether aspects of quality of teaching are measured in the same way across pre-service teachers and their students by means of measurement invariance analyses. To do so, 272 pre-service teachers in teacher education rated aspects of their quality of teaching, and were rated by their 4851 students. Measurement invariance across these perspectives was tested in multilevel structural equation models. Strong measurement invariance held for two aspects of quality of teaching; for the third, one item lacked weak measurement invariance. Pre-service teachers perceived their quality of teaching lower than their students. In conclusion, aspects of quality of teaching can be compared across perspectives, and teacher education should encourage pre-service teachers to use students’ feedback as a valuable resource for improving their quality of teaching.     

基于UWN的协同创新知识网络中知识流动效率测度

知识流动效率对创新绩效有着重要影响,在协同创新领域更是如此。为有效测度协同创新知识网络的知识流动效率,本文提出一种基于无向加权网络（Undirected Weighted Network, UWN）的知识流动效率测度模型。首先,基于协同创新知识网络的节点特性、节点间关系特性,构建协同创新知识网络的UWN模型;综合考虑协同创新知识网络中知识流动效率的多重影响因素,提出一个新的知识流动效率测度模型,并进一步提出该模型在成员管理中的延伸应用;最后,通过某智能手机开发企业的应用案例验证本文所提模型与方法的可行性与有效性。     

生产性服务业集聚、空间溢出与产业结构升级——基于全国239个地级城市的实证检验

在生产性服务业集聚快速发展的背景下,对集聚的空间溢出效应进行研究。以全国239个地级城市为样本,在地理距离权重和经济距离权重矩阵下分别建立空间计量模型定量测度生产性服务业集聚对产业结构升级的影响并比较其行业差异。结果显示,我国生产性服务业整体集聚不仅能够对本地产业结构升级产生促进作用,还对周边城市的产业结构升级存在正向溢出效应,且经济发展特征对产业结构升级的空间相关性影响更大;不同生产性服务行业集聚对本地及周边城市的产业结构升级影响各异,其中信息服务业集聚促进作用最大,其余依次为物流业集聚、金融业集聚,科技服务业集聚和商务服务业集聚。
