Judging the Constructive Impacts of Communication Technologies: A Business Education Study

Through an IBM partnership, Acadia University has the benefit of an infrastructure that places a laptop computer in the hands of some 4000 faculty and students on campus. Coupled with anytime–anyplace campus access to the computer network, the setting offers unique opportunities to study the pedagogical impacts of the use of computers in classroom instruction.University business administration courses have routinely employed case study approaches in the delivery of some course content. The research described follows the use of an elaborate case study communications networking system being used in a business course on competitive intelligence. Though the technology collage allows for certain opportunities to promote quality instruction, not all aspects of technology use were found to be productive. This paper provides an analysis of the appropriateness of technology usage in the context of a single business education course.     

“Can any fraction be turned into a decimal?” A case study of a mathematical group discussion

This case study examines two days of teacher-led large group discussion in a fifth grade about a mathematical question intended to support student exploration of relationships among fraction and decimal representations and rational numbers. The purpose of the analysis is to illuminate the teacher’s work in supporting student thinking through the use of a mathematical question embedded in a position-driven discussion. The focus is an examination of the ways that the emergence of mathematical ideas is partially shaped by complex interactions among the mathematical contents of the question, the inherent properties of the discourse format and participant structure, and the available computational methods. The teacher’s work is conceptualized in terms of actions and practices that coordinate these diverse tools, in constant response to students’ concurrent use of them. This revised version was published online in July 2006 with corrections to the Cover Date.     

Training program in child abuse for community health workers

A wide range of health workers in the community provide care for families that abuse or have a potential for abusing their children. Frequently these workers are unable to work effectively because of difficulty dealing with feelings aroused by contact with such families.An experimental child abuse training program for community health workers was designed by a pediatrician, a social worker, a public health nurse and two child psychiatrists. This program included a six-month study group which met weekly to focus on feelings and conflcts aroused during the course of work with abusing or potentially abusing families.Through analysis of the group experience, the leaders identified eleven sets of feelings or conflicts which seemed to interfere consistently with effective delivery of care: 1)anxieties about a) being physically harmed by angry parents and b) about the effects of a decision; 2) denial and inhibition of anger; 3) need for emotional gratification from clients; 4) lack of professional support; 5) feelings of incompetence; 6) denial and projection of responsbility; 7) feeling total responsibility for assigned families; 8) difficulty separating personal from professional responsibility; 9) feelings of being a victim; 10) ambivalent feelings a) toward clients and b) about one's professional role; 11) need to be in control.This type of group experience seems to be an effective method for exploration and resolution of feelings and conflicts.

美国研究型大学慕课商业模式的现状反思——基于加州大学欧文分校慕课教学人员的集体访谈

作为全球慕课运动的急先锋,以加州大学欧文分校为代表的美国研究型大学秉持可持续发展理念,创建了一系列成功的慕课商业模式,实现收支平衡或基本的盈利。不过,美国研究型大学的慕课商业模式仍然面临许多现实困难,亟待有效的解决方案。为此,尝试运用集体访谈来对加州大学欧文分校慕课商业模式进行研究,全面揭示存在的问题。具体而言,主要包括:核心资源的管理有待改进;关键活动的效果面临质疑;客户关系的深化成效有限;收入来源的拓展遭受阻碍;渠道通路的提升存在不确定性;价值主张的彰显尚需明确;客户细分的平衡非常有限;成本结构的优化尚需努力;重要伙伴的关注亟待加强。面对严峻的市场环境,可以尝试构建基于慕课的三层商业模式画布,推进慕课的可持续发展。     

A theory of instruction for introductory programming skills

ABSTRACT

Background and Context: Current introductory instruction fails to identify, structure, and sequence the many skills involved in programming.

Objective: We proposed a theory which identifies four distinct skills that novices learn incrementally. These skills are tracing, writing syntax, comprehending templates (reusable abstractions of programming knowledge), and writing code with templates. We theorized that explicit instruction of these skills decreases cognitive demand.

Method: We conducted an exploratory mixed-methods study and compared students’ exercise completion rates, error rates, ability to explain code, and engagement when learning to program. We compared material that reflects this theory to more traditional material that does not distinguish between skills.

Findings: Teaching skills incrementally resulted in improved completion rate on practice exercises, and decreased error rate and improved understanding of the post-test.

Implications: By structuring programming skills such that they can be taught explicitly and incrementally, we can inform instructional design and improve future research on understanding how novice programmers develop understanding.     

少数民族女童低学业成就的归因分析与对策

国务院人口普查办公室1990年全国10％人口抽样调查资料表明，在全国三百多万6—14岁不在校人口中，西部地区就占了1／3强，其中56．96％的人口是女性，即在西部地区有65万多6—14岁的女童因为各种原因应该在校读书而没有在校。能否加快西部12省(区、直辖市)“普九”的步伐，有效解决西部地区少数民族女童教育问题，成为落实“两基”目标的重中之重。
