Through this learning progression, we hope to assist the users to understand the sequence how the learners grasp the concepts of quadratic functions, and to offer the users a reference for designing appropriate learning activities; thus, the learners can learn the concepts of quadratic functions more efficiently and better. Based on this purpose, our main research question is “what the content of the learning progression for quadratic functions of secondary students in Taiwan?” In order to answer the research question, we used literature analysis, qualitative interview and questionnaire, and went through three periods to obtain the results. First period is exploration period. The purpose of exploration period is to make us familiar with the method of depicting a learning progression, and to collect the probable learning performance when secondary students learn the concepts of quadratic functions. We used literature analysis to understand what the mathematicians and the educators expected students to learn, what content students really contacted with, and what kind of error students had through the past study. Then, we designed a draft for interview, and interviewed 8 students in total. Finally, we depicted an initial learning progression for quadratic functions. To validate the learning progression, we developed an assessment and collected the data of forty-two 16-year-old students and thirty-eight 17-year-old students. Since we didn’t test the validity and reliability of this assessment, we only collected the data in qualitative analysis rather than quantitative analysis. Second period is adjustment period. The purpose of adjustment period is to solve the challenge we faced in exploration period, and to adjust the content of the learning progression for quadratic functions. We reviewed more literature to understand the learning progression theory and to understand what kind of learning performance students had in the past research. Finally, we depicted a new initial learning progression for quadratic functions. To validate this new initial learning progression, we came to the third period, validation period. We used questionnaire and developed a new assessment based on the new initial learning progression. After testing the validity and reliability of this assessment, we collected the data of 604 students, through 14-year-old to 18-year-old, and finally analyzed the data of 399 senior high school students because of bad design of assessment for junior high school students. In addition, we used qualitative interview and invited five veterans of mathematics teachers to arrange 41 descriptions in our learning progression as one of evidence for validation. There are six levels, from 0 to 5, in our new initial learning progression for quadratic functions with the concepts including definition, graphing, the meaning of coefficients, transformations, extreme values and symmetry of quadratic functions. However, we could only depict 13.67% students in our data with this learning progression, and had 24.3 to 48.8 percent exact agreement and 68.3 to 87.8 percent adjacent agreement with five veterans of mathematics teachers. This informs us of the room of improvement of our learning progression. Based on students’ data, we combined the contents of level 4 and 5, and deleted the descriptions about the thoughts of transformations. We could finally depict 63.04% students in our data after the adjustment. And, we put the descriptions about the thoughts of transformations back into the learning progression by teachers’ data. Since we had no idea to use the teachers’ data, we mainly relied on students’ data supplemented by teachers’ data to adjust our learning progression.
