Problem representation in specific domains has raised great attention in the past years. In mainland China, research of the primitive physics problem teaching has been booming in the physics education domain recently. This study proposes six representations in the process of solving problems for middle school students, including abstraction representation, assignment representation, image representation, physics representation, methodology representation and mathematics representation. The measuring instrument of primitive physics problem for junior high school students was developed according to previous research and the principle of “Objectively Evaluating Subjective Questions”. The participants were 113 grade nine students in mainland China. The results of confirmatory factor analysis confirm the effectiveness of the measuring instrument. A weak correlation between the measuring instrument of primitive physics problems and Lawson Classroom Test of Scientific Reasoning (LCTSR) was found. Therefore, we believe that the primitive physics problem solving ability is a unique ability which is different from the general reasoning ability. This study demonstrates that using the measuring instrument of primitive physics problem to measure junior high school students’ ability of problem solving is promising.

The main target of the current study is to explain the metacognition of junior high school students with Field Independent (FI) and Field Dependent (FD) cognitive styles in mathematics problem-solving. It should be noted that the statistical population of this study was all junior high school students in the Sragen regency in the 2018/2019 academic year. To reach the research purpose, different instruments such as the cognitive style tests, the problem-solving exercises, and the interview guidance were used. Data analysis was carried out by data collection, data reduction, data presentation, and conclusion. The results indicated that the students who have field-independent cognitive style had high self-confidence that they were able to solve the problem correctly, able to do planning steps, able to make important decisions for themselves, so they can solve the problem properly. Students with FD cognitive style are completely confident that their answer is correct, but they have not yet clarified the steps they need to solve their problems and have not yet focused on their shortcomings in mathematics problem solving, so their task results in mathematics problem-solving incorrectness answer.   Keywords: Cognitive style; Mathematics problem solving; Metacognition

Back Stage

One of the goals of learning mathematics is students can solve the problems. PISA problems can be used to bring up the problem solving activities. Keirsey's personality type is chosen because it offers possibility on differences in each personality type. It is based on the characteristics in taking and processing information, making decisions, and patterning the implementation of their tasks. The aim of this research is describing the profile of junior high school students about PISA problem solving based on personality type. This research is a qualitative descriptive research using test and interview methods. The subjects consist of four students, which are guardian, artisan, rational, and idealist. The results showed that on the understanding the problem stage, all students read the questions and were capable in identifying the information in the question. Then represented what is known and unknown. At the devising a plan stage, the four subjects were able to link the information that was known with prior knowledge to make a plan. At the carrying out the plan stage, the four subjects used the appropriate knowledge to implement the settlement plan that has been made. At the looking back stage, all the students examine their solutions.Keywords: problem solving, PISA questions, personality type
