ANALISIS KEMAMPUAN ARGUMENTASI SISWA PADA MATERI FUNGSI DI KELAS VIII SMP NEGERI 6 PALU : Analysis Of Argumentation Ability Students On Functional Materials In Class VIII Smp Negeri 6 Palu
Full text linkThe aim of this study was to obtain a description of the analysis of the argumentation abilities of class VIII students at SMP Negeri 6 Palu on function. This type of research is descriptive research type. The approach used in this study is a qualitative approach. The subjects of this study were three students in grade VIII of SMP Negeri 6 Palu for the 2021/2022 academic year. Students at a high level of mathematical ability have good argumentation skills because they are able to state what information is in the problem and at each step of completion (Data), are able to provide statements to solve a problem (Claim), are able to show data as well as provide evidence that is able to support statement put forward (Warrant), and able to reject the statement and explain the conditions under which the statement is not valid (Disclaimer). Students at the moderate level of mathematical ability have fairly good argumentation skills because they are able to provide statements to solve a problem (Claim), are able to show data as well as provide evidence that is able to support the statements put forward (Warrant). Students at low ability levels have less argumentation skills because they have not provided enough information about what is in the problem and at each step of completion (Data), have not been able to provide statements to solve a problem (Claim), have not been able to provide evidence capable of supporting statements made stated (Warrant), and also has not been able to provide an explanation of the conditions under which the statement is not valid (Rebuttal)
PROFIL PENYELESAIAN SOAL PADA MATERI LUAS PERMUKAAN KERUCUT OLEH SISWA KELAS IX SMP NEGERI 1 KASIMBAR: Profile for Solving HOTS Questions On The Cone Surface Area Material by Students of Class IX SMP Negeri 1 Kasimbar
Full text linkThis study aims to profile the completion of HOTS questions on the conical surface area material by SMP Negeri 1 Kasimabar students based on differentiated cognitive levels. This type of research is qualitative research. The subjects of this study were 2 students of different genders taken from class IX SMP Negeri 1 Kasimbar. The research subjects were one student with high mathematics ability with female gender (LN), and one student with high mathematics ability with male gender (MS). The data collection techniques in this study were written tests and in-depth interviews. The test given to the research subjects was a HOTS problem test on cone surface area material at the cognitive level of analyzing (C4). The results of this study indicate that the profile of solving HOTS problems on the surface area of the cone by students with high mathematics ability LN at the cognitive level of analyzing is correct, because the subject can distinguish information, organize by creating a structure in systematic problem solving and attribute by making conclusions based on the information obtained very well. While the profile of HOTS problem solving of cone surface area by MS high mathematics ability students at the cognitive level of analyzing is good, because MS subjects are also able to distinguish information and organize by creating structures in systematic problem solving, it's just that at the stage of attributing MS subjects are still lacking, because at the stage of attributing

ANALISIS PEMECAHAN MASALAH PERSAMAAN NILAI MUTLAK SISWA SMA NEGERI 1 PAMONA SELATAN BERDASARKAN LANGKAH POLYA DITINJAU DARI GAYA KOGNITIF: Analysis Of The Absolute Value Equation Problem Solving Of Students Of State Senior High School 1 Pamona Selatan Based On Polya's Steps Reviewed From Cognitive Style
Full text linkThe objectives of this research are; (1) to obtain a description of the problem solving of class X MIPA1 students who have the FI cognitive style in solving the absolute value equation at SMA Negeri 1 Pamona Selatan, (2) to obtain a description of the problem solving of class X MIPA1 students who have the FD cognitive style in solving the value equation absolutely in SMA Negeri 1 Pamona Selatan. This type of research is a qualitative descriptive research. The subjects in this study were 2 students taken from 20 students of class X MIPA1 SMA Negeri 1 Pamona Selatan who took the GEFT test. The results of this study indicate that students' problem solving with field independent cognitive style is based on Polya's steps, namely; (1) in understanding the problem, the field independent subject can write down completely what is known and asked in the question correctly, (2) at the planning stage, the field independent subject can relate the things that are known and asked in the question, so that in making problem-solving planning field independent subjects make plans correctly, (3) at the stage of implementing the problem-solving plan field independent subjects can perform calculations properly and correctly, (4) at the stage of rechecking the answers field independent subjects are able to recalculate the answers they get and able to provide conclusions on the answers obtained. The results of student problem solving with field dependent cognitive style are: (1) in understanding the field dependent subject problem can write completely what is known and asked in the question correctly, (2) at the stage of making field dependent subject planning is able to plan problem solving but inaccurate, (3) at the stage of implementing the problem-solving plan, the field dependent subject could not do the calculations correctly, (4) at the stage of re-examining the answers, the field dependent subject did not re-examine the answers obtained and did not provide conclusions on the answers he had obtained. Based on the description above, it can be concluded that the FI subject carried out the four Polya steps in solving the absolute value equation problem solving, in contrast to the FD subject who only performed Polya's three steps in solving the absolute value problem solving
