| As the last problem in the math part of high school entrance examination, the comprehensive problem is designed to assess the stu dents’ skills in computing, graph-recognition, modeling and application. Once encountered it, many students got clueless because they found it difficult either to rearrange the given information, or to find the connections within. This is more true to the middle school students.Hence, the researcher focused on the Year 9 students in Shanghai No. 3 Girls’ Junior School, taking various measures such as questionnaire survey, experiments and action studies. She analyzed the obstacles they have in solving the comprehensive problems, and proposed some effective teaching strategies and suggestions. Finally, the author proposed some pertinent teaching suggestions, which are of great value in fostering and developing students’ math problem solving skills.According to this essay, the author found that the year 9 schoolgirls have difficulties in reading and comprehension, number-shape combination, knowledge construction and psychological preparation, which has close connections with their gender and physical situation, teacher’s teaching methods, student’s non-intelligent factors and parents’ expectation.According to the results, the author began to use some new teaching strategies. One is the group cooperative learning, and the other is emphasizing the combination of number and shape; and the more accurate graphing. The experimental group’s after test(2nd mock exam and the monthly exam) were used to verify the effectiveness of the new teaching strategies. |
