This study examined the effectiveness of pair programming in four lecture sections of a large introductory programming course. We were particularly interested in assessing how the use of pair programming affects student performance and decisions to pursue computer science related majors. We found that students who used pair programming produced better(More)
The purpose of this study was to investigate the effects of pair-programming on student performance in an introductory programming class. Data was collected from approximately 600 students who either completed programming assignments with a partner or programmed independently. Students who programmed in pairs produced better programs, completed the course(More)
I n recent years, the growth of extreme programming (XP) has brought considerable attention to collaborative programming. Developed over a 15-year period by Kent Beck and his colleagues , Ron Jeffries and Ward Cunningham [1], XP is a computer software development approach that credits much of its success to the use of pair programming by all programmers,(More)
Social workers and welfare recipients operate within the same institutional framework and share a working and/or lived knowledge of poverty, but they occupy different social and economic positions. To gain a better understanding of intergroup attitudes, the author compared how social workers and welfare recipients explain poverty and perceive the welfare(More)
The high regenerative capacity of adult skeletal muscle relies on a self-renewing depot of adult stem cells, termed muscle satellite cells (MSCs). Androgens, known mediators of overall body composition and specifically skeletal muscle mass, have been shown to regulate MSCs. The possible overlapping function of androgen regulation of muscle growth and MSC(More)
OBJECTIVE Given high rates of co-occurring mental and substance use disorders among homeless youths and poorly understood facilitators of and barriers to service use, this study explored factors influencing service use among homeless youths with co-occurring disorders. METHODS Focus groups were conducted with 23 youths age 18 to 26 with co-occurring(More)
Research in the realm of Pair Programming in computer science students has begun to explore the methods for accomplishing the benefits. However, valid measurements of the opinion on adopting a pair programming in the practical sessions are required to be drawn, before concluding. An Attitude Survey Test (AST) was conducted before implementing Pair(More)
OBJECTIVE WE CONDUCTED A SYSTEMATIC REVIEW TO ANSWER THE QUESTION: Among youth ≤18 years of age with a mental disorder, does substance use prevention compared to no prevention result in reduced rates of substance use/abuse/disorder (SUD)? The review was requested by the Ontario Ministry of Health and Long-term Care through the Canadian Institutes for Health(More)
