课堂教学行为分析引论

课堂教学行为本身是一个包含多种互动要素的系统,而且具有层级性结构。课堂教学行为分析就是运用行为理论和教学原理对其构成要素及各个要素之间的关系进行分析,即要素论分析,同时对其实现单位及各个实现单位之间的内部转化关系进行分析,即过程论分析,从而进一步探明课堂教学行为在学生发展中的独特规律。进行课堂教学行为分析有三个方面的原因:教学论学科建设的需要、教学设计的需要和转化教学观念的需要。课堂教学行为分析的主要方法有课堂观察法、课堂语言行为互动分析法和人种志方法。     

Development and Construct Validation of the Mentor Behavior Scale

Researchers suggest that certain supportive behaviors of mentors could increase the benefits of school-based mentoring for youth. However, the literature contains few validated instruments to measure these behaviors. In our present study, we aimed to construct and validate a tool to measure the supportive behaviors of mentors participating in school-based mentoring programs. The mentor behavior scale (MBS) was developed drawing on the premises of the mentoring sociomotivational model. Two hundred and fifty-three (253) college students participating in an eight-month school-based mentoring program completed an experimental version of the MBS and different measures of the quality of the mentoring relationship at two times during the program. The questionnaire has good internal consistency coefficients and adequate factorial structure, with the exception of the factor autonomy support. Moreover, three dimensions of the MBS predict mentoring relationship quality and the perceived usefulness of the intervention. Recommendations for the use and improvement of the MSB are proposed.     

How They Search,How They Feel,and How to Serve Them? Information Needs and Seeking Behaviors of Chinese Students Using Academic Libraries

ABSTRACT

America has become a choice for international students to study abroad because of its advanced education system and environment. Libraries become a way for international students to access resources and experience campus life, while Chinese students are increasing gradually as the biggest component of international students. This article investigates how Chinese students use American academic libraries and their information needs and seeking behaviors, as well as Chinese students' satisfaction with library facilities, resources, and services, and their expectation for other services. The article aims to better understand Chinese students, analyze their search strategies, and better provide relevant library services for them.     

The Difficult Patron Situation

Summary

Problem/difficult patron incidents that occur in libraries are on the rise. Library administrators and library employees have attempted to decrease the number of incidents by providing staff training and formulating policies and rules to control the situation. The purpose of this article is to share the proactive steps that the Education and Behavioral Sciences Library, Penn State University Libraries, took to prevent or decrease the incidences of difficult patrons as the library prepares to relocate. The focus was on assisting the frontline staff members, who work on the reference desk, to acquire the competencies they need to provide consistent quality reference services to patrons, and to reduce incidences of unsatisfied, difficult, and problem patrons.     

Students' Perceptions of Classroom Group Work as a Function of Group Member Selection

Course: Small Group Communication

The purpose of this assessment was to examine whether differences exist between students who self-select their classroom work group members and students who are randomly assigned to their classroom work groups in terms of their use of organizational citizenship behaviors with their work group members; their commitment to, trust in, and relational satisfaction with their work groups; and their self-reports of affective learning and cognitive learning. Participants were 126 students enrolled in a small group communication course. While students who self-select their group members and students who are randomly assigned to their groups do not differ in their use of organizational citizenship behaviors with their classroom work group members, students who self-select their classroom work group members do report higher levels of commitment, trust, and relational satisfaction, as well as more affective learning and more cognitive learning, than students who are randomly assigned to classroom work groups.     

Promise Fulfilled? An EBSCO Discovery Service Usability Study

Discovery tools are the next phase of library search systems. Illinois State University's Milner Library implemented EBSCO Discovery Service in August 2010. The authors conducted usability studies on the system in the fall of 2010. The aims of the study were twofold: first, to determine how Milner users set about using the system in order to better inform customization choices, which in turn would create better search experiences, and second, to find out whether discovery tools fix the problems of federated search. With federated search technology, users often felt frustrated by the search experience. Some reasons for the frustration included a desire for better ways to determine the relevancy of search results and for more information about the material included in the records. The authors determined that while many federated search problems were solved, some issues persisted. Overall, the move to EBSCO Discovery Service at Milner Library has been a positive experience for its users.
