Students’ Errors Analysis in Finishing A Problem Solving Test Based on Newman Procedures in Trigonometry Materials

Male and female students' mathematical reasoning skills in solving trigonometry problems

“…Students who had a low skill to generalize the statement could be caused several things: they did not elaborate and synthesize the characteristics of cosine function given, did not understand the concept of function, or did not understand the method for solving a two-variable linear equation system. Some previous studies revealed that most students still had a low skill to understand the principle and concept of mathematics, specifically trigonometry (Dewanto et al, 2018;Hidayati, 2020;Wahyuni & Widayanti, 2020). The result of the Mann-Whitney test showed that the p-value of U statistics was 0,088, and it was more than 0,05.…”

“…The trigonometry function is selected as a material to measure students' MRS in generalizing a statement. These trigonometry topics were selected because students still carried out many errors in these topics reported by prior studies (Altiner & Dogan, 2018;Hidayati, 2020;Sartika & Fatmanissa, 2020, Satriani et al, 2020Usman & Hussaini, 2017;Wahyuni & Widayanti, 2020). So, every sub-topic in the trigonometry established in this study represents every indicator of MRS selected in this study (See Table 1).…”

“…Therefore, they are unable to clarify the truth of Arman's argument stating that the wooden beam can be used to cross over the river. Students who have a low skill in clarifying the truth of an argument can be affected by some factors, such as misunderstanding the meaning of the problem (Ahmad et al, 2018;Dewanto et al, 2018;Hidayati, 2020;Wahyuni & Widayanti, 2020) and misconceptions of a concept such as they are unable to establish the formula used (Ahmad et al, 2018;Dewanto et al, 2018;Hidayati, 2020;Rohimah & Prabawanto, 2019;Satriani et al, 2020).…”

“…The trigonometry topic is selected in this study because several studies showed that the students' errors rate in solving trigonometry problems tends to be high. The errors include; do not understand the problems given, do not master the basic concept of trigonometry, perform basic arithmetic operations, determine the formula to solve the problem and write the final answer (Altiner & Dogan, 2018;Hidayati, 2020;Sartika & Fatmanissa, 2020, Satriani et al, 2020Usman & Hussaini, 2017;Wahyuni & Widayanti, 2020). The studies about students' MRS from the gender perspective have been conducted.…”

Analisis Pola Kesalahan Jawaban Siswa Pada Materi Hitungan Kimia

“…Hal ini menunjukkan bahwa sebagian besar siswa SMA/MA belum bisa menemukan pendekatan yang tepat dalam menyelesaikan soal hitungan kimia yang diberikan. Kesalahan transformasi dapat disebabkan karena siswa tidak dapat menerapkan informasi yang terdapat pada soal kedalam persamaan yang benar (Wahyuni & Widayanti, 2020). Hal ini sejalan dengan hasil penelitian Abdullah et al, (2015) yang menemukan bahwa sebagian siswa kesulitan dalam mengubah masalah matematika kedalam persamaan matematika yang tepat untuk menyelesaikan permasalahan yang terdapat dalam soal.…”
