Pattern-oriented instruction and its influence on problem decomposition and solution construction

Novices often experience difficulties in problem analysis and solution construction. Pattern-oriented instruction (POI) is a pedagogical approach based on incorporating patterns into instruction design. It is well-grounded in cognitive theories concerning knowledge construction and organization as well as the acquisition of expertise in problem solving. We show that the incorporation of algorithmic patterns through POI may enhance the construction of algorithmic problem-solving knowledge. Findings of a comparative research study showed that novices who studied according to the POI approach exhibited better problem-solving competence than those who studied in a traditional manner. Specifically, they were more competent in problem decomposition and solution construction.
