| The purpose of this study was to determine if there is any difference between successful and unsuccessful students' organization of knowledge and ability to link relevant knowledge pieces. In other words, do difficulties stem from poor understanding of pieces required for successful problem solving or inability to link those pieces? Moreover, we studied the influence of students' cognitive development levels, proportional-reasoning abilities, working memory capacities, conceptual understanding of the particle nature of matter, and the mole concept on their ability to solve stoichiometric problems. Think-aloud problem-solving protocols were also used to understand the differences between successful and unsuccessful students' knowledge structures and behaviors during problem solving. Characteristics of successful and unsuccessful students were determined through tests, audio and video tapes analyses, and subjects' written works. In analyses of the materials, significant differences were found between both groups. |
