A Study of the Effectiveness of Web-Based Homework in Teaching Undergraduate Business Statistics

Web-based homework (WBH) Technology can simplify the creation and grading of assignments as well as provide a feasible platform for assessment testing, but its effect on student learning in business statistics is unknown. This is particularly true of the latest software development of Web-based tutoring agents that dynamically evaluate individual students' skill level and purport to respond with appropriate, targeted teaching to improve learning efficiency. In this article, we compare traditional, textbook-based homework assignments with three systems of WBH for undergraduate business statistics courses: ALEKS, PH Grade Assist, and custom-made online quizzes in Blackboard. These systems represent a range of media from artificial intelligence–based tutoring to instructor-controlled objective testing. Using a common assessment test, we compare the performance of students taught with these different systems. Our study finds, as we anticipated, that student performance depends significantly upon teacher experience and student academic competence. Once these factors are controlled for, however, the technique used to deliver homework makes little difference in student success. In contrast to other published research, we do not find any advantage to automated tutoring and identify some limitations of this approach based on both instructor and student feedback.

对参考文献中增刊著录的探讨

增刊是在正刊之外出版的连续出版物,但《信息与文献参考文献著录规则GB/T 7714—2015》对增刊著录格式没有明确规定。参考文献中增刊著录不规范的问题非常普遍,主要体现为增刊期号和页码的著录形式不同。分析其原因,主要体现为不同期刊和数据库对增刊期号和页码的标志不同。因此提出规范增刊著录的建议,使作者和编辑有例可循。

What is meant by inclusion? An analysis of European and North American journal articles with high impact

The purpose of this review is to further our knowledge about what is meant by inclusion in research addressing the topic. While it is common to remark that inclusion is defined in different ways in research, few attempts have been made to map and analyse different types of definitions and whether there are patterns to be find in how the concept is used. The 30 most cited journal articles from a North American and a European research arena were selected for analysis. Each article was analysed in relation to genre, theoretical tradition and inclusion concept used. The review yielded several important results. To name a few, a divide was identified between position articles, with developed discussions about and analyses of the meaning of inclusion, and empirical articles, where inclusion signifies that children with disabilities are placed in the mainstream. In addition, writing within a critical theoretical tradition was much more common among positional papers. Further, both arenas are dominated by Anglo-Saxon researchers. It is argued that the conceptual confusion characterising the field impedes its development.
