This qualitative study aims to describe the conceptual understanding of prospective mathematics teachers at STKIP PGRI Lumajang by determining examples and non-examples of functions. This research was conducted by giving tests and interviews with 12 subjects. Data were analyzed using Miles & Huberman model. This study showed that the subjects investigated whether paired to determine a given statement is a function or not. Subjects focus on specific expressions, e.g., or others that they have previously recognized as a function. However, some subjects used the vertical line test to determine a given graph represents a function or not, although they were unable to explain why the vertical line test was the appropriate method. Their understanding is limited to procedural knowledge such as mental representations and incomplete concept images, then failing to be comprehensively linked to the definition of the concept of function

This research aims to describe the students’ metacognitive failure in constructing proof and the scaffolding support. The participants of this qualitative case study were eight preservice mathematics teachers of six-semester, State University of Malang. We carried out a test about proof construction problems in Abstract Algebra. Then we verified the data using triangulation of constant comparative method from a test and a task-based interview with the stimulated recall. The results indicated two groups of students in proving strategy. Group I performed “appropriate” syntactic strategy and Group II vice versa. Blindness was experienced by the subject that does not recognize errors detection or the ambiguity of the proof. Mirage occurred when the subject recognizes an error detection on the proper strategy or application of a theorem, then is unable to verify the truth of his work. Misdirection appeared when the subject recognizes a lack of progress, then uses an incomplete or irrelevant concept. Vandalism emerged with no progress or detection of errors of the strategy then the subject performs some irrelevant steps to the issue or uses a misconception. Practically, the teachers can use these results for learning innovations in scaffolding-based proof courses. The scaffolding might need some development and application in supporting students to overcome difficulty in proving mathematical sentences.

This research uses a descriptive type, with a qualitative approach. Data collection techniques in the form of giving tests with the think-aloud method and semi-structured interviews. The research instrument consisted of a problem test with investigative-based and interview guidelines. The research participants consisted of three grade 12 students each with high, medium, and low mathematical abilities. The results of this study indicate that at the stage of understanding the problem, metacognitive activity appears in the form of awareness and evaluation. However, the low participant was not able awareness in a good way and the medium participant was not doing a careful evaluation of the results. In the planning stage, the high and medium participants currently use regulation activities by thinking about the right strategy. Evaluation activities, such as believing in the effectiveness of the strategy and assessing the results appropriately. In the stage of implementing the plan, the high and medium participants are using regulation activities by monitoring the planned solutions properly. Evaluation activities are carried out with an appropriate assessment of each result. However, the opposite appeared for low participant in both previous stages. In the stage of looking back, evaluation activity appears in the form of assessing the suitability of answers to the context of the problem with investigative nuances, but no metacognitive activity was found in low participant.

The aim of this research is to describe junior high school students’ problem solving profile in the Pythagoras Theorem problem based on the cognitive styles of FI and FD. The results of this study is the FI subject is better than the FD subject. The FI subject understand the problem very well, arranging a solution plan well, implementing a plan properly, and looking back well. Different from previous research, subject FI make error even though not any Polya’s step. Nevertheless, The FD subjects are categorized as lacking in the step of understanding the problem, devising a plan with deficient category, implementing the plan without looking back on the solution, so it is categorized as lacking and errors emerged at almost every step. Some errors in problem solving showed by FI and FD subjects, so for further research need to analyses errors and the other cognitive style.
