Contrast to force and motion concepts, studentsâ difficulties related to physics concepts underlying mechanical wave propagation has getting less attention in physics education research. This study exposed common studentsâ difficulties in solving conceptual problems related to mechanical wave propagation. Subject consisted of 128 first-year students in physics department of UM, enrolling the Introductory Physics II in 2013/2014 academic year. Data was gathered using two-tier, multiple choices test with Confidence Scale Rating. The study concluded that some fundamental concepts of wave such as general mathematical representation of wave propagation, motion of medium particles, and the relationship of v = λf, were not well understood by most students; even many students hold misconceptions. The study suggested further research to explore the causes of studentâs difficulties more outentically, for example, using think aloud or clinical interview methods.Kontras dengan topik gaya dan gerak, kesulitan siswa terkait konsep-konsep yang melandasi fenomena perambatan gelombang masih kurang mendapatkan perhatian para peneliti pendidikan fisika. Artikel ini mengangkat kesulitan umum yang dialami mahasiswa dalam memecahkan masalah konseptual terkait fenomena perambatan gelombang. Subjek penelitian terdiri atas 128 mahasiswa tahun pertama jurusan fisika UM yang mengikuti perkuliahan Fisika Dasar II tahun akademik 2013/2014. Analisis didasarkan pada jawaban mahasiswa terhadap soal pilihan ganda dan tingkat keyakinan mahasiswa terhadap ketepatan jawabannya. Penelitian menyimpulkan bahwa konsep-konsep fundamental yang meliputi representasi matematis tentang karakteristik umum gelombang berjalan, gerakan partikel medium saat dilewati gelombang, dan hubungan  belum dipahami dengan baik oleh sebagian besar mahasiswa; bahkan banyak mahasiswa yang terindikasi mengalami miskonsepsi. Disarankan untuk dilakukan penelitian lanjutan untuk mengeksplorasi lebih dalam dan lebih otentik penyebab kesulitan tersebut, misalnya menggunakan teknik think aloud atau interview klinis.

Studentsâ difficulties commonly are analyzed based on misconception theory. This paper aimed to analyze studentsâ difficulties on the rotational dynamic based on resource theory. The subject of research consisted of 108 first-year undergraduate students of Physics Education, State University of Malang. Firstly, the students were asked to solve 15 multiple-choice questions and gave open explanation. We then implemened a constant comparative method to identify and categorize some resources that students employed in solving several problems that most the students failed to respond correctly. The results indicated that the students had difficulties in solving problems related to the torque and the equilibrium of rigid body. The studentsâ difficulties were not merely caused by the lack of correct knowledge. Instead, they have the correct knowledge or resources but they activated them on inappropriate context. The students will be successfully used the resources to solve problems if they activated them in the right context.

Impulse momentum theorem is one of the fundamental principles of physics, especially in mechanics. Therefore, studentsâ understanding of impulse and momentum will contribute to their success in learning physics. This study exposed common students difficulties in solving problems related to impulse and momentum. The subjects consisted of 175 students of a Senior High School in Malang, 70 students of grade XI who recently learned about impulse and momentum and 105 students of grade XII who relearned the topic for national examination preparation. The data were gathered using multiple-choice test with open explanation and confidence rating scale. The study concluded that the studentsâ difficulties were not only caused by their lack understanding of the concepts but also by their deficiency in using vectors.

This study explored effectiveness of Predict-Observe-Explain (POE) strategy to enhance concept comprehension of junior high school students in hydrostatic pressure and Archimedes law concepts. Subjects of this study were 31 students of a private junior high school in East Flores in even semester year 2015/2016. By mixed-method design, this study concluded that (1) average score of concept comprehension was significantly increase (p = 0.000) from pre-test (36.77) to post-test (63.26) with strong category of effect size (1.62), and moderate category of N-gain (0.40); (2) learning was also succeed identifying some misconceptions and remedied it. Those misconceptions were: (a) hydrostatic pressure was influenced by liquid volume and or the shape of the container, (b) an object was floated for there was air within, (c) a sunken object had no buoyant force, and (d) the magnitude of buoyant force was equal to liquid volume; (3) some of common problems around the students in applying hydrostatics concept and buoyant force were as follow (a) related to mathematical representation of hydrostatic force Ph = P0 + Ïgh, most all students interpreted h as the depth measured from the bottom of the liquid column (not from the surface of the liquid as it should be), (b) related to buoyant force, the problem depended on the context where the question given. In context of immovable objects in a certain fluid, almost all student was hard comparing buoyant force magnitude to the weight. In context of sliding object in liquid, almost all students failed to explain the object position to its buoyant force.

Penelitian ini bertujuan untuk melihat pemahaman konsep dan konsistensi mahasiswa dalam menggunakan konsep saat menyelesaikan soal fisika pada topik kecepatan dalam berbagai format representasi. Dalam penelitian ini digunakan 4 soal pilihan ganda beralasan dalam format representasi berbeda. Penelitian dilakukan pada 26 mahasiswa S1 pendidikan fisika dan 22 mahasiswa S1 fisika tahun pertama di Universitas Negeri Malang. Hasil penelitian menunjukkan pemahaman konsep kecepatan masih tergolong rendah yang ditandai dengan rata-rata skor mahasiswa hanya mencapai 43,49. Selain itu, alasan yang diberikan mahasiswa menunjukkan bahwa mahasiswa tidak konsisten dalam mendefinisikan kecepatan karena pemahaman yang belum utuh. Beberapa kekeliruan mahasiswa diantaranya: (1) kecepatan adalah posisi per satuan waktu tempuh, (2), (3) tanpa memahami bahwa persamaan tersebut hanya benar jika percepatan konstan, (4), dan (5) tidak memperhatikan tanda (+/-) pada kecepatan. This study aims to look at the students conceptual understanding and the studentsâ consistency in used concept when them solved the physics problems in velocity with variety of representation formats. There are 4 MCQs reasoned in a different format representations to achieve these goals. The study was conducted on 26 S1 physical education students and 22 S1 physics students in first year. The results showed that the studentsâ conceptual understanding is still relatively low which is characterized by an average score of students reached only 43.49. Moreover, the reason given students showed that students are still not consistent in defining velocity due to knowledge in pieces. Some studentsâ mistakes are: (1) Velocity is the position per unit of time, (2), (3) without understanding that this equation is only true if the acceleration is constant, (4), and (5) do not pay attention to the sign (+/-) on velocity.

Amongst other things, Indonesian history was rife with religious conflicts. Religious differences had thus far been factored in the causes of intolerance amongst believers of different religions. This study examined how religious tolerance that was established in Sidoasri village where Christians and Muslims were living together. This research used a qualitative descriptive method, where it would describe and explain data from the subject research on the form of religious tolerance in Sidoasri village. The results of this research show that religious tolerance is always built through the long process by way of mediating various past conflicts. Religious dogma has never been a cause of intolerance. Social, cultural, political, and economic factors are decisive in founding religious tolerance.
