The Social Embeddedness of Academic Online Groups in Offline Networks as a Norm Generating Structure: An Empirical Test of the Coleman Model on Norm Emergence

This paper analyzes two questions. First, under which conditions does a norm emerge in academic online groups that prescribes members to help others during group discussions? Second, what effects does such a norm, and other social conditions, have on the contributing behavior of researchers during online discussions? It is argued that the Coleman model (1990) on the emergence of norms points to an important condition that facilitates the realization of such a norm. According to the Coleman model (1990) a dense network among members of a group tends to strengthen a group norm. The paper makes a distinction between different kinds of academic online groups. The criterion of the distinction is the extent to which within the membership a highly integrated research community exists. An online group with a highly integrated research community is called to have a high degree of social embeddedness of its online communication in offline networks. It is hypothesized that a high degree of embeddedness has a number of effects. A higher degree of embeddedness leads to a stronger help-prescribing norm. The stronger the norm the more researchers send online answers to questions of their co-members during public online discussions. Furthermore, a high degree of embeddedness increases the answering behavior of researchers directly because it provides opportunities to gain reputation within the academic community through contributing to the discussion. The study makes use of data that consist of a combination of survey data and observed data of the communication behavior of researchers in about 50 international academic emailing lists. The results provide evidence for the expected effect of embeddedness on the strength of the norm and for the effect of embeddedness on the answering behavior of researchers. The strength of the help-prescribing norm indirectly influences the answering behavior.     

An investigation into the teaching of mathematics to undergraduate economics students

This article attempts to present a novel application of a method of measuring accuracy for academic success predictors that could be used as a standard. This procedure is known as the receiver operating characteristic (ROC) curve, which comes from statistical decision techniques. The statistical prediction techniques provide predictor models and their goodness-of-fit; in addition, ROC analysis allows to assess the accuracy of the ability to discriminate from success and failures cases of a classifier or predictive model, and so it could be considered complementary to others more commonly used. Thus, the ROC curve is used to compare and interpret the relative contribution of each university entrance factor in the correct classification as success or failure of the academic performance, as well as to establish cut-off scores for admissions and counselling purposes. It is revealed that the ROC analysis allows us to identify the better university entrance factor for each subject in predicting students’ academic success.

课程思政背景下分析化学辩证元素探索及教学实践

In the university, analytical chemistry is an important basic course for junior college students. There is a variety of dialectical views, rules, and relationships of materialism in analytical chemistry. Fully excavating these dialectical elements and infiltrating them into the classroom teaching process is necessary. This will not only help students deeply understand the subject knowledge, but also cultivate their dialectical thinking mode, establish the correct worldview and scientific methodology. This is conducive to the same resonance frequency between knowledge education and thinking education, and fits the current course ideological and political education. In the present paper, combining many years of teaching practice, the author briefly explains the integration of dialectical elements in analytical chemistry with the corresponding teaching content.     

基于AL的学业评价新体系在高职药物化学中的构建与实践

为了提高高职高专药物化学课程的教学效果,在药物化学教学中引入课堂层面的教学评价构建新的学业评价体系“促进学习的评价”,并在整个教学过程中持续实施,同时将评价结果进行反馈从而指导和促进后续的教学活动。结果表明,药物化学课程的学习时间、学习内容以及学业成绩均比教改前有较大幅度的提高,并且受到学生的高度认可。该学业评价体系不仅大大激发了学生的学习动力,改善了教师的课堂教学效果,提高了学生的学业水平,而且大获学生的欢迎。     

基于学科思想方法的命题与教学反思——以初中学业考试化学试题为例
