Abstract

Abstract: This study identified student’s difficulty on doing test about work and energy. This study was conducted on 68 high school students at 11th grade who had took work and energy material. Type of this research was descriptive with survey method. Technique of collecting data was test with 15 items two tier's instruments which have been validated by expert. The student’s reasons in answering were used to identify possible causes of errors. Test result showed that the average student's test score is 50.65 with a scale of 100. Common difficulties for students were applying multiplication of the dot product force acting on objects and the movement objects when the movement of objects is presented through graphs, applying work-kinetic energy theorems, misinterpreting relations of gravity and height of objects on the incline, and determine the graph relation of energy with height object as a description of the movement of objects with parabolic paths and influenced by the external forces of the system. This finding can be used as a reference to overcome student difficulties through appropriate learning strategies. Abstrak: Penelitian ini bertujuan untuk mengidentifikasi kesulitan siswa SMA dalam mengerjakan soal-soal usaha energi. Penelitian dilakukan pada 68 siswa SMA kelas XI yang telah menempuh materi usaha-energi. Jenis penelitian ini adalah deskriptif dengan metode survei. Teknik pengumpulan data yang digunakan yaitu tes dengan instrumen berupa soal pilihan ganda beralasan berjumlah 15 butir yang telah divalidasi oleh ahli. Alasan siswa dalam menjawab digunakan untuk mengidentifikasi kemungkinan penyebab kesalahan. Hasil tes menunjukkan bahwa skor tes rata-rata siswa adalah 50,65 dengan skala 100. Kesulitan yang umum terjadi pada siswa yaitu menerapkan perkalian dot product gaya yang bekerja pada benda serta perpindahan benda jika pergerakan benda disajikan melalui grafik, menerapkan teorema usaha energi kinetik, salah memaknai hubungan usaha oleh gaya gravitasi dengan ketinggian benda pada bidang miring, serta menentukan grafik hubungan energi dan ketinggian yang benar sebagai deskripsi pergerakan benda dengan lintasan parabola dan dipengaruhi gaya eksternal sistem. Temuan ini dapat digunakan sebagai referensi untuk mengatasi kesulitan-kesulitan siswa melalui strategi pembelajaran yang tepat.

Abstract

This research aims at identifying conceptual understanding and Physics scientific processing skill of students in IDEAL learning strategy with formative feedback and IDEAL learning only without formative feedback. It employed semi-experimental design using posttest only control group design. The sampling technique used random sampling. This research took two classes of XI graders of Natural Science classes from SMAN 2 Banjarmasin. The control class was taught by using IDEAL strategy only without formative feedback. While the experimental class was taught by using IDEAL strategy with formative feedback. There is a significant difference of conceptual understanding and Physics scientific processing skill of students between IDEAL strategy with formative feedback and IDEAL strategy without formative feedback. It further affirms that students’ conceptual understanding in the class taught by IDEAL strategy with formative feedback is higher than the other. As well, students’ scientific processing skill in the class taught by IDEAL strategy with formative feedback is higher than the other.

Abstract

Abstract: Information, knowledge, and skills needs are never static, always changing and evolving. Thus, students are required to master the capability as a lifelong learners of self-directed learning skills (SDL). The purpose of this study is to describe the level of students' SDL skills, the factors that are related and affect the skills of SDL high school students majoring in MIPA. Descriptive research carried out refers to the steps of research Loeb et al. The research step is carried out only until the fifth stage, namely: (1) identifying a phenomenon; (2) consider features of the most prominent phenomena; (3) identifying the construction or preparing the research plan; (4) determine the observable patterns in the data; and (5) communicate patterns in the data describing the reality of phenomena. The results showed that the student's SDL skills were categorized with a tendency at moderate to upper levels. The lowest SDL student skill score was 53 out of a total score 220. Awareness factors, learning strategies, and evaluations are strongly correlated with SDL skills. While the factors of learning and interpersonal skills are highly correlated with the SDL skills. Outside learning factors such as grade, school, gender, and age levels have an effect of 4.3% on SDL skills. The results of this study can be used as a reference of teachers and researchers who need information about the student's SDL skills and related factors. Abstrak: Informasi, pengetahuan, dan kebutuhan terhadap keterampilan tidak pernah bersifat statis, selalu mengalami perubahan dan perkembangan.Dengan demikian, siswa dituntut untuk menguasai kapabilitas sebagai pembelajar seumur hidup yaitu keterampilanself-directed learning (SDL).Tujuan penelitian ini adalahmendeskripsikan tingkat keterampilan SDL siswa serta faktor-faktor yang berhubungan dan berpengaruh terhadap keterampilan SDL siswa SMA jurusan MIPA.Penelitian deskriptif yang dilaksanakan mengacu pada langkah-langkah penelitian Loeb dkk. Langkah penelitian hanya dilaksanakan hingga pada tahap lima, yaitu: (1) mengidentifikasi suatu fenomena; (2) mempertimbangkan fitur dari fenomena yang paling menonjol; (3) mengidentifikasi konstruksi atau menyusun perencanaan penelitian; (4) menentukan pola yang dapat diamati dalam data; dan (5) mengkomunikasikan pola dalam data yang menggambarkan realitas fenomena.Hasil penelitian menunjukkan bahwa keterampilan SDL siswa tergolong beragam dengan kecenderungan pada tingkat moderat ke atas.Skor keterampilan SDL siswa terendah adalah 53 dari skor total 220. Faktor kesadaran, strategi belajar, dan evaluasi berkorelasi kuat dengan keterampilan SDL.Sedangkan faktor kegiatan belajar dan kemampuan interpersonal berkorelasi sangat kuat dengan keterampilan SDL.Faktor di luar belajar seperti tingkat kelas, sekolah, jenis kelamin, dan usia berpengaruh sebesar 4.3% terhadap keterampilan SDL.Hasil penelitian ini dapat digunakan sebagai referensi guru maupun peneliti yang membutuhkan informasi mengenai keterampilan SDL siswa dan faktor-faktor terkait.

Abstract

This study aims to determine the differences in scientific literacy of students who were given inquiry learning through a real-virtual Monte Carlo experiment with students who were given conventional learning. This study used quasi experimental design with pretest-posttest control group. The results showed that the ability of students who were taught by inquiry learning models through real-virtual Monte Carlo experiments had higher scientific literacy than those taught with conventional models, it also applied well to students with high and low initial abilities. The results of the average gain in scientific literacy scores also showed a higher value between students who studied with the inquiry model through a real-virtual Monte Carlo experiment with students who studied with conventional models. The novelty of this research is combining real and virtual activities become real-virtual Monte Carlo by using the inquiry learning model to improve students' scientific literacy.
