Abstract
Complex problem solving is a competency necessary for taking any careers in the 21st century world. The goal of this study was to enhance a class of grade 9 students’ Complex problem solving competency by using an engineering design problem-based learning. The participants were 38 ninth graders of a laboratory school located in Bangkok. A set of complex problem solving test was used for tracking the students’ complex problem solving development. Each test consisted of one problem scenario and seven open-ended questions in relation to the 7 components of the complex problem solving. Findings from content analysis reveal that the majority of students arrive at the high competency level after experiencing three cycles of teaching through the engineering design problem-based learning. Top three components of complex problem solving with which the students present high development are: 1) identify problem, 2) evaluate the complexity of the problem, and 3) identify the relationship among variables related to the problem, respectively. However, the component by which many students struggle with is to evaluate the appropriateness of the solution. This study provides suggestions for teachers on how to create learning activities that promote children’s development of complex problem solving.
