The students in Figure 9.1 adapted a mono-answer proof model and complied with numbers to solve the problem. The students in Figure 9.2 also adapted mono-answer proof model, but they complied with the number line as listed to represent the relationship among variables. The students in Figure 9.3 adapted the systematic substituting formula to prove each problem and acquired the correct answer.
Conclusion and Comments
The findings presented provided evidence for students’ ability in their reasoning of algebraic problem, and could use some effective representations and complied with practical strategies to generalize and solve algebraic problem. Although there were only half of the anticipants who got the right answer and gave the correct explanation, it was also noted that too many students did not have a clear understanding of what the problem was asking. It can be concluded that there was no reasoning behind the processes in the majority of strategies coded. Thus, there is a need for teachers to teach their students how to write a good explanation addressing both the ‘how’ and ‘why’ aspects of their strategies. This explanation would validate the students’ thinking as they wrote up their reasons. In addition, teachers need to ask students to explain what and why they are doing during the problem solving process. Students also need to reflect on what they are doing.
Reasoning, conceptual understanding and explanations will not easily evolve in classrooms unless opportunities are provided for the students to engage in sense-making processes. This can be done by
