Problem Solving Task

This research is a qualitative descriptive study. The research subjects consisted of female students with introverted personality and female students with extrovert personality. The instruments used in this study consisted of a personality test instrument, interview guidelines, and problem solving tasks (TPM). Data collection was carried out by means of contextual problem solving task-based interviews. The data validity test was conducted by means of time triangulation. The data analysis used refers to the 3 flows of data analysis from Milles & Huberman, namely data reduction, data presentation and conclusion drawing. The results of this study can be concluded as follows. Introverted students mentioned all the information contained in the questions correctly in a halting voice, while extrovert students mentioned all the information contained in the questions correctly and smoothly. The two students solved the questions in two ways even though the methods used were routine procedures that were commonly used by students. In re-examining the results obtained, the two students matched the results obtained with the steps in one method with another method.

AbstrakPenelitian ini bertujuan untuk mendiskripsikan serta memaparkan strategi metakognitif siswa dalam memecahkan masalah matematika. Strategi metakognisi merupakan proses yang berurutan yang digunakan untuk mengontrol aktivitas kognitif dan memastikan bahwa tujuan kognitif telah dicapai. Penggunaan Strategi metakognitif dalam pemecahan masalah matematika akan menuntun siswa untuk memahami dan mengontrol proses berpikirnya, menganalisis, objektif, cermat dan logis dalam memecahkan masalah matematika yang sedang dihadapinya. Penelitian dilaksanakan di kelas VIII SMP N 16 Kupang, yang terdiri dari 34 siswa dengan menggunakan metode angket, soal tes dan dilengkapi dengan adanya wawancara. Berdasarkan hasil penelitian menunjukkan bahwa dari empat aspek metakognitif yaitu: aspek kesadaran, aspek strategi kognitif, aspek perencanaan dan aspek pengecekkan kembali mendapatkan respon siswa pada rata-rata 2.90, 2.74, 2.95, 2.90 serta diperkuat oleh hasil pengerjaan soal dan wawancara, maka dapat di simpulkan bahwa kemampuan strategi metakognitif siswa dalam memecahan masalah matematika siswa kelas VIII SMP N 16 Kupang dapat dikelompokan ke dalam katagori baik.Kata kunci: Pemecahan Masalah, Matematika, Strategi metakognitif AbstractThis study aimed to describe and explain the student metacognitive strategies in solving mathematical problems. Metacognitive strategies is a sequential process that is used to control the cognitive activity and ensure that the cognitive objectives have been achieved. The use of metacognitive strategies in solving mathematical problems will lead students to understand and control the process of thinking, analyzing, objective, accurate and logical in solving mathematical problems at hand. The experiment was conducted in class VIII SMP N 1 Kupang, which consists of 34 students by using questionnaires, test questions, and features an interview. Based on the results of the study showed that of the four aspects of metacognitive namely: Aspects of consciousness, aspects of metacognitive strategies, planning aspects and aspects checking back to get the average student response 2.90, 2.74, 2.95, 2.90, and reinforced by the workmanship about and interviews, it can be concluded that metacognitive strategies in a student's ability to solve mathematical problems in SMP N 16 Kupang can be grouped into either category.Keywords: Math , Problem Solving, Metacognitive Strategies
