The relationship between mental computation and relational thinking in the seventh grade

An Analysis of Students' Mathematical Reasoning and Mental Computation Proficiencies

“…The findings of the study show both Primary 5 and Primary 6 students have a moderately high level of mental computation proficiency with scores of 15.36 and 22.9 respectively (from a maximum score of 30). On the other hand, students obtained a low-level proficiency in the mathematical reasoning test with scores of 14.83 (SD = 6.76) and 18.74 (SD = 6.45) for primary 5 students and primary 6 students respectively from a maximum score of 70. How well do current exams grades reflect the student's proficiency in mathematical reasoning?…”

“…Research decades ago has also shown that students strong in mental computation also display strong reasoning sense [15,16]. Similarly, the current trend also suggests that instruction in mental computation and estimation can support the development of reasoning in children [17,18,6]. In fact, mental computation and estimation is expected at school level as it covers over 80% of problem-solving situations and it involves computing numbers accurately without the assistance of any gadgets or devices.…”

Pengembangan E-Book Interaktif Berbasis Animasi Bagi Siswa Sekolah Menengah Kejuruan

“…Salah satu konsep yang diajarkan dalam kurikulum Sekolah Menengah adalah aljabar, sebuah topik yang seringkali siswa mengalami kesulitan dalam belajarnya (Kindrat, 2018). Berdasarkan hasil observasi pada salah satu materi aljabar yaitu baris dan deret di Sekolah Menengah Kejuruan (SMK) YP 17-1 Madiun, tercatat 60% siswa yang memperoleh nilai di atas Kriteria Ketuntasan Minimum (KKM).…”

The Concept Image of Students and Teachers about the Equal Sign

“…Many researchers in various countries have explored learners' understanding of the equal sign in primary, secondary, and college schools (eg, Alibali, et al, 2007;Baiduri, 2015;Carpenter, et al, 2005;Fuchs, et al, 2014;Kindrat & Osana, 2018;McNeil, et al, 2006). This suggests that understanding the equal sign has become the focus point of reform and research efforts in mathematics education as a proven "problem" that is strong and long-term for primary, secondary, and even college students.…”
