Search and Research on Economics of Pair Programming

This research aims to answer two research questions. Is pair programming more cost-effective than solo programming? In what situations is pair programming more cost-effective than solo programming and vice versa? In order to answer these, we adopted and extended economic models from past research. Two main conclusions can be drawn from our study. First, across the ranges of parameters studied, pair programming is more economically feasible only in a limited number of instances. Second, in order to achieve the economic benefit, pair programming either needs to have advantages in all three parameters (speed, defect, and defect removing) or have substantial advantages in two of them if on the other one pair is roughly equivalent to solo programming. We also identified specific parameter ranges for situations where a) pair programming is more economical, b) solo programming is more economical, and c) the two programming methods are equivalent. Implications of this research are discussed.     

A parametric analysis of linear integer programming problems

Parametric programming may be utilized to obtain restrictions to linear programming relaxations to linear integer programming problems. The purpose of such approaches is to reduce the size of the subproblems that appear subsequent to solving the relaxed linear programming problem. The optimal dual variables to the linear programming problem provide information regarding the difference between the continuous linear programming optimal objective function value and that of the integer linear programming objective function value.     

Cognitive Differences Between Procedural Programming and Object Oriented Programming

Software development is moving from procedural programming towards object-oriented programming (OOP). Past studies in cognitive aspects of programming have focused primarily on procedural programming languages. Object-oriented programming is a new paradigm for computing. Industry is finding that programmers are having difficulty shifting to this new programming paradigm. Findings in prior research revealed that procedural programming requires Piaget's formal operation cognitive level. New from this research is that OOP also requires Piaget's formal operation cognitive level. Also new is that OOP appears to be unrelated to hemispheric cognitive style. OOP appears to be hemispheric style friendly, while procedural programming is preferential to left hemispheric cognitive style. The conclusion is that cognitive requirements are not the cause for the difficulty in shifting from procedural to OOP. An alternative possibility to the difficulty is proactive interference of learning procedural programming prior to learning object oriented programming.

DISCOVER: AN INTELLIGENT DISCOVERY PROGRAMMING SYSTEM

Much of research in programming environments for novices has been polarized toward two opposite domains: guided programming environments and free programming environments. Intelligent programming tutors and systems that represent guided environments concentrate mainly on helping novices in acquiring programming skills through a series of problem-solving situations. Most of these systems tend to ignore the significance of a preproblem solving, dynamic, visualization-based, and free environment which would help novices in compiling an effective programming knowledge through a discovery-like process. Free programming environments, on the other hand, concentrate exclusively on helping novices to build correct programming knowledge through visible, exploratory, and free discovery environments. These systems generally tend to neglect the issue of supporting those aspects of intelligent diagnosis and tutoring, through which novices can transform their program knowledge into programming skill. A system has been developed called DISCOVER that occupies a unique niche between the two domains discussed above. The system emphasizes a synthesis-based framework which integrates free programming with guided programming features, and supports software visualization and immediacy of feedback to come up with an environment that facilitates learning programming through discovery and guidance. To assess the usefulness of the design framework presented in this paper, two pilot performance evaluations were conducted. The results provided a number of interesting insights into the implication of incorporating visualization and immediacy features, along with intelligent program diagnosis into the design of programming systems intended mainly for novices.
