Discussion of how to teach programming skills to novice programmers focuses on the use of a program animator that uses a copies model of recursion to teach the recursive function. Various mental models are reviewed; testing the recursion animator is described; and possibilities for further research are suggested. (12 references) (LRW)

A detailed analysis and computer-based solution to a puzzle addressing the arrangement of dominoes on a grid is presented. The problem is one used in a college-level data structures or algorithms course. The solution uses backtracking to generate all possible answers. Details of the use of backtracking and techniques for mapping abstract problems…

The report describes improved algorithms within a computer program for identifying spelling and word order errors in student responses. A "markup analysis" compares a student's response string to an author-specified model string and generates a graphical error markup that indicates spelling, capitalization, and accent errors, extra or…

Central State University (Ohio), under a contract with Nichols Research Corporation, has developed a World Wide web based workshop on high performance computing entitled "IBN SP2 Parallel Programming Workshop." The research is part of the DoD (Department of Defense) High Performance Computing Modernization Program. The research…

The objectives of this research were to review existing computer-assisted instruction systems for propositional calculus proofs or elementary logic and to develop an instructional computer program that guides students in the valid construction of propositional calculus proofs. The system is unique in that it provides assistance at each step of the…
