The paper discusses a certain type of competitions based on distance interaction of a participant with simulation models of concepts from discrete mathematics and computer science. One of them is the "Construct, Test, Explore" (CTE) competition, developed by the authors, the other is the Olympiad in Discrete Mathematics and Theoretical…

In a seminal article published in 2006, Jeanette Wing described computational thinking (CT) as a way of "solving problems, designing systems, and understanding human behavior by drawing on the concepts fundamental to computer science." Wing's article gave rise to an often controversial discussion and debate among computer scientists,…

This paper describes an investigation of problem sequencing as part of a symposium presenting theoretical concerns and research findings regarding several diverse types of strategies for designing and presenting instructional materials. The first step involved analyzing a set of problems, to determine the knowledge (rules) required for solving the…

Discusses a study which investigated whether a computer simulation model could suggest subroutines that were instructable and whether instruction on these subroutines could facilitate subjects' solutions to the problem task. (JM)

The jackknife is a general inferential technique intended to ameliorate the problems associated with inadequate sampling theory. The research reported herein is directed at investigating the utility of the jackknife for establishing confidence intervals on and testing hypotheses about the disattenuated correlation coefficient for small samples. A…

This paper describes a National Science Foundation-sponsored project at Louisiana Technological University to develop computer-based laboratories for "hands-on" introductions to major topics of computer science. The underlying strategy is to develop structured laboratory environments that present abstract concepts through the use of…

This paper describes the use of Java to develop a variety of educational materials to supplement both traditional instruction and Internet-based instruction. Efforts have focused on three projects that vary in course level, content, and style of interaction. Unlike the simple Java applets on the Web, these are very sophisticated simulation…

In this paper the theory that human thinking proceeds according to the computer model, or symbol manipulation, is reviewed and challenged. The research used as subjects five highly rated tournament chess players who "thought aloud" during a chess game to provide tape recorded protocols of decisions made while playing. These protocols…

Society and education are changing rapidly, and since computers are playing a significant role in these changes it is imperative that secondary school teachers become more fully informed about computers. Computers are of interest to learners because they have led to new theoretical developments, such as automata theory, have many practical…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
