Misunderstanding is one of the causes of junior high school students in the city of Lamongan learning difficulties, especially studying physics material. The aim of this study was to investigate whether the three-tier test able to identify student misconceptions. Based on the research objectives to be achieved, this research is a descriptive study using descriptive qualitative methods in explaining the research results. The technique of collecting data through tests is by using a Three-Tier Test diagnostic instrument and open interview. Diagnostic results data are expressed in terms of percentage of the students’ conception categories. The sample of this research is the students who have received the Heat material, seventh graders. The subjects of this study were grade VII students totaling 150 students with details of 60 male students and 90 female students with age around 12 to 13 years old. Besides using written tests, interviews were conducted on several students to verify the results of the three-tier test. From the analysis of three-tier test diagnostic data students showed that from 47% including the criteria to master the concept, while the remaining 38% experienced misconceptions, 5% guess or not believe in the answers, and 10% don’t know the concept. Conclusions of this study is the three-tier test that has been developed on Heat topic is able to identify misconceptions students quickly and accurately. Therefore, a three-level diagnostic test tool that has been developed to diagnose students ‘misconceptions about temperature and heat materials can identify students’ misconceptions quickly and accurately.

Mathematics is the basis for other sciences and students in schools from elementary school to college must learn and master it. But in reality, many students get the results of daily math tests under the minimum achievement criteria, especially on the derivative material of algebraic functions. This study has the aim of producing and developing appropriate learning media products which will then be tested for validity and practicality based on expert validation and student response questionnaires. This research is a research and development on 30 students of class XII PH 2 SMK Negeri 1 Lamongan. This research method uses the ADDIE model. results obtained in this study are as follows: 1) The results of the validity of the media obtained from the validation of media and learning materials, get an average rating of 87.5% in the "Very Valid" category, 2) The results of the student response questionnaire to determine the practicality of the media show a rating of 90.5% in the "Very Practical" category.

Penelitian ini merupakan penelitian deskriptif kualitatif yang bertujuan untuk mendeskripsikan proses koneksi matematis mahasiswa calon guru dalam memecahkan masalah matematika. Subjek penelitian dalam penelitian ini adalah mahasiswa FKIP Universitas Muhammadiyah Malang dan Universitas Islam Darul Ulum Lamongan. Subjek dipilih berdasarkan tes GEFT. Proses koneksi matematis dilihat dari hasil wawancara dan jawaban tertulis subjek penelitian dalam memecahkan masalah berdasarkan langkah–langkah Polya. Langkah-langkah Polya diantaranya (1) understand the problem, (2) device a plan, (3) carry out the plan, (4) look back. Hasil penelitian menunjukkan bahwa mahasiswa dengan gaya kognitif Field Independent mampu melakukan koneksi internal dan koneksi eksternal pada tiap tahap pemecahan masalah dengan baik daripada mahasiswa dengan gaya kognitif Field Dependent.

Students, basically, possess prior knowledge or conception regarding a concept, even before they study it formally in the school. Sometimes, their conceptions are inconsistent with scientific concept and resulting misconceptions. Some studies found that students encounter misconception of some concepts, particularly in Physics. Three-tier Test is an instrument used to identify student’s misconception and lack of knowledge. A misconception should be differentiate from a lack of knowledge because remediation of a misconception is more difficult than remediation of a lack of knowledge. Besides, both of them may entail different instructional methods. This study focused on diagnosing students’ misconceptions of heat using Three-tier Test. The study is aimed to explain in what concepts the students encounter misconceptions of heat and to explain the prevalence of students’ misconceptions of heat. The method used in this study was a descriptive-exploratory research with non-experimental design. The sample of this study was 150 Grade VII students of five different State Junior High School in Lamongan, East Java. The data was collected through written test using Three-tier Test and administered once. The results showed that students encounter misconceptions in 6 concepts of heat comprising energy, heat, temperature, mass, specific heat capacity, vaporizing, boiling, pressure, boiling point, freezing, and freezing point. Moreover, the results showed that 88% of the students encounter misconception, where the most frequently appeared is misconception about energy and heat that is objects could have a certain quantity of heat in them.

Tujuan penelitian ini adalah untuk mengetahui kemampuan berpikir kritis siswa yang memiliki self-concept tingi, sedang dan rendah dalam menyelesaikan soal aritmatika sosial tipe HOTS di kelas VII MTs Darul Ulum Al-Cholily tahun pelajaran 2021/2022. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif dengan menggunakan 6 subjek yang telah dipilih. Teknik pengumpulan data yang digunakan adalah dengan memberikan angket self-concept, tes soal kemampuan berpikir kritis dan wawancara, soal yang digunakan dalam mengukur kemampuan berpikir kritis berupa soal essay yang bejumlah 2 buah. Wawancara bertujuan untuk mengetahui kemampuan berpikir kritis siswa yang menjadi penguat tes soal yang telah dikerjakan subjek. Berdasarkan hasil penelitian disimpulkan bahwa subjek yang memiliki self-concept tinggi sudah memenuhi indikator kemampuan berpikir kritis dengan baik tetapi masih ada yang harus diperbaiki. Subjek yang memiliki self-concept sedang sudah memenuhi indikator kemampuan berpikir kritis, tetapi pada menentukan strategi subjek masih kurang tepat dalam melakukan operasi hitung, pada tahap membuat penjelasan lebih lanjut subjek masih kurang tepat dalam memberikan kesimpulan yang diinginkan soal. Subjek yang memiliki self-concept rendah masih belum memenuhi semua indikator kemampuan berpikir kritis seperti pada tahap menentukan strategi subjek masih kurang dalam menjelaskan langkah-langkah yang digunakan dan masih kurang tepat dalam melakukan operasi hitung, pada tahap membuat penjelasan lebih lanjut subjek masih kurang tepat dalam memberikan kesimpulan yang diinginkan soal.
