碩士 === 國立臺中教育大學 === 數學教育學系在職進修教學碩士學位班 === 101 === The purpose of this study is to 20 single steps of the preparation of a country second graders subtraction word ITEMS quiz, students answer on questions of reaction and problem-solving performance, and part to the Partial Credit S-P Chart Analysis, diagnostic questions and analyze students' learning conditions and types of learning, and then explore the circumstances of their understanding of the concept. This study to Yunlin County Elementary School sophomore as the research object, the results are as follows: 1.Students' mathematical problem solving Students in mathematical problem solving of the four major types of addition and subtraction word problems in descending order: combine, compare, change and equalize. The study can be found in children is highest in the combine types of problem-solving accuracy rate (86.41%). The lowest correct rate (67.25%) and equalize types of problem solving. 2.Partial Credit S-P Chart Analysis Results and Discussion The coefficient of variation of the test results of this study, five classes D* the range between 0 and 1, so the teachers teach and learners reaction with close. Display through the SP table of five classes and the students' attention factor, the three classes of students in the area of A ratio of 61.9%, the best performing class students not only in the class of higher degree and can carefully learn from the information found the number of students of the five classes and low degree of share of the proportion of the total number of classes are low, and four classes of students compared to other classes and low degree of the number of students more and more. Broadly speaking, the generally five classes learning situation into a normal distribution, the heterogeneous composition of the learning situation not much good learning steady state. 3.Students' analysis of the types of errors The study display that students' problem-solving type of error the following: (1)Lack of proper language and semantic knowledge. (2)Misuse of keywords to determine computing strategy. (3)Calculation error. Keywords：math word problems, Partial Credit S-P Chart Analysis, caution index, types of errors.
