| 总结: | Students' success in stoichiometry problem solving depends mainly on their understanding of the concept of mole and problem representation ability. Unless we can make students and teachers believe the importance of mastering the conceptual understanding of the problems, the challenge of enhancing students' performance in solving stoichiometry problems would remain a daunting task. The purpose of this study was two-pronged in nature. First, it attempted at identifying the major factors influencing students' performance in stoichiometry problem solving. By doing so, this study also tried to determine whether the major factors identified by the researcher constituted a solid ground for stoichiometry teaching. Second, the present study aimed at probing problems faced by students and teachers in stoichiometry learning and teaching in the classroom. 108 respondents took part in the study. A14-item written subjective test was used to estimate the correlations of students' understanding of the concept of mole, problem representation ability and mathematical ability and their performance in stoichiometry problem solving. A structured 7 verbal interview questions was used to gauge teacheres' perceptions and a 6-item written interview questions were used to probe students' perceptions. A think-aloud interview consisting 3 stoichiometry problems was used to probe students' difficulties in solving the problems. The MRA suggests that students' understanding of the concept of mole and their problem representation ability are significant predictors. The statistical result seemed to be supported by the qualitative analysis of findings of this study suggest that mathematical ability is not a significant factor in determining students' success in solving the problems. |
