Abstract

Abstract. The aims of this study to identify  the profile of students’  conseptions and misconceptions on the concept of reaction rate using a four-tier multiple choice diagnostic test instrument reported in the form of misconception profiles consisting of students' conceptions, students' misconceptions and the causes of misconceptions experienced by students. Based on the results of the study shown (1) the students’ conception profile is as much as 78% understand the concept, 21% misconceptions and 1% do not understand the concept, (2) the profile of student’s misconceptions in each sub-material that misconceptions on sub-material of concentration 16%, temperature 19%, surface area 41% and catalyst 24% and as many as 1 student (3%) including the high misconception category, 22 students (67%) included in the medium misconception category and 10 students (30%) were in the low misconception category. Students’ misconceptions vary in different causes such as; associative thinking 59%, preconceptions 25%, incomplete resoning 13%, humanistic thinking 2% and incorrect intuition 1% .  Keywords: four-tier multiple choice, misconception, reaction rate

Abstract

Pandemi Covid-19 membawa dampak besar bagi dunia pendidikan di Indonesia, dengan sistem pembelajaran jarak jauh menuntut guru dan peserta didik untuk lebih inovatif dan komunikatif, salah satunya dengan penggunaan multimedia interaktif Collisions sebagai media pembelajaran saat daring. Penelitian ini bertujuan untuk mengetahui hasil belajar dan persepsi peserta didik melalui pembelajaran berbasis multimedia interaktif Collisions pada materi ikatan kimia. Subjek penelitian yaitu peserta didik SMA GIKI 1 Surabaya dan SMA Unggulan Amanatul Ummah Pacet, Mojokerto. Metode penelitian yang digunakan adalah pre-eksperimen dengan rancangan One Group Pretest-Posttest Design. Teknik pengumpulan data yang digunakan yaitu teknik tes dan angket. Teknik analisis data yang digunakan yaitu deskriptif kuantitatif. Peningkatan hasil belajar peserta didik SMA GIKI 1 Surabaya dapat dikategorikan tinggi karena rata-rata n-gain yang mencapai 0,89. Peningkatan hasil belajar peserta didik SMA Unggulan Amanatul Ummah Pacet, Mojokerto dapat dikategorikan tinggi karena rata-rata n-gain yang mencapai 0,88. Persepsi peserta didik terhadap multimedia interaktif Collisions termasuk kategori sangat baik dengan persentase positif pada tiap aspek mencapai >80%.  Berdasarkan hasil penelitian disimpulkan bahwa hasil belajar peserta didik meningkat dan peserta didik memberikan persepsi yang sangat baik melalui pembelajaran berbasis multimedia interaktif Collisions pada materi ikatan kimia.

Abstract

The purpose of this study was to describe the implementation of assessment for learning-oriented learning and learning outcomes on acid-base titration material in class XI. This research was conducted in class XI-1 and XI-5 SMA Giki 1 Surabaya. The results showed that the implementation of assessment for learning-oriented learning on acid-base titration material as a whole received very good criteria. This is evidenced by the average percentage of implementation scores at the first meeting of 99.3% and 98.5% for classes XI-1 and XI-5, as well as the second meeting of 99% and 99.5% in classes XI-1 and XI-5 with the criteria for each meeting is very good. Learning outcomes through assessment applications for learning-oriented learning have increased in one sample t-test. The test found that posttest2 XI-5 - posttest2 XI-1 in both classes got a p-score> 0.05, then Ho was accepted, and Ha was rejected. Thus, the score for posttest 2 XI-1 was smaller than that of posttest 2 XI-5. There is no significant difference in posttest 2 between the two classes. So from this, it can be concluded that learning that applies the Assessment for Learning-oriented student worksheet is effective even though the average results of the two classes show differences.
