Is social capital effective for online learning?

The popularity of online social networking has heightened academic interest in social capital. However, few studies have investigated the role of social capital in online learning. Using exploratory and confirmatory factor analyses of data from online MIS classes, we find that online learning facilitates social capital formation mostly in terms of the dimensions of community, trust, collective action and cooperation, communication, and sociability and inclusion, depending on the media-based human interaction forms of online learning employed. Structural equation modeling confirms a causal effect of social capital on student satisfaction. Social capital is also found to positively affect learning outcomes as measured by students’ group project scores but not class scores. The study's contribution to the literature and practice are discussed.     

引入图形化方法改革非计算机专业程序开发教学模式

文章分析目前高校非计算机专业中程序开发类课程教学效果不佳的现象,提出其主要原因在于难以在有限的学时内兼顾编程语言基础训练和专业问题编程技能两方面的培养。以地理信息系统专业的二次开发课程为案例,通过引入图形化编程的概念和方法,帮助学生最大限度地克服对编程语言复杂繁琐的语法规范的理解障碍,实现将课程重点放在专业应用问题的程序化思维方法和编程技能的训练上,实际的教学效果充分显示了这一模式的有效性。     

The history of broad and general education in scientific psychology: The foundation for professional psychology education and training.

The article provides the historical roots and rationale for providing professional psychologists with knowledge of the underpinnings in core scientific areas of psychology with two goals–knowledge of those scientific areas themselves and as the basis for further understanding the integration of science and practice to improve professional service delivery. This article discusses the early roots of the applied areas within psychology and the changes in curricular expectations in accreditation to the current provisions for the accreditation of doctoral programs in professional psychology. After the historical introduction, the article discusses the current use of the concept of broad and general training as the basis for current practice in accreditation of programs in professional psychology and for the practice as a licensed psychologist. Finally, the article provides some initial discussion of the different perspectives in the rest of the section regarding how best to provide students with appropriate knowledge for competence in scientific underpinnings of professional psychology.

Cement-stabilized fly ash base courses

Various demonstration projects have been carried out in The Netherlands with cement-stabilized fly ash as a base course. Usually these courses were made of 100 parts by mass of fly ash; 10 parts by mass of cement; 20 to 30 parts by mass of water. However, the projects were not quite successful since delamination was observed, and long-term strength, after a period of six years of performance, appears to be much smaller than expected on the basis of preliminary laboratory research. A model for pozzolanic reaction of fly ash recently developed by Fraay and Bijen pointed out that the reactivity of fly ash is influenced greatly by the pH value of the pore water. A pH of at least 13 is required to initiate fly ash pozzolanic reaction in a Portland cement environment. Pore water extraction measurements showed that the pH of cement-stabilized fly ash often has a substantially lower value. In this high-volume fly ash application the effect of the acidity of fly ash is much greater than in ordinary concrete with cement replaced by fly ash up to 30%. By addition of NaOH and/or sodium silicate to the mixing water, the pH value can be increased above the ‘threshold’ value.

Tests were carried out with different types of class-F fly ashes and with different NaOH concentrations in the mixing water. The results show an increase in compressive strength of up to 300% depending on the type of fly ash, and a substantial decrease in the rate of water absorption.
