Abstract

Learning difficulties experienced by students in a subject can affect their learning outcomes. Learning difficulties can be caused by misconceptions experienced by students or knowledge barriers. It can be happened because chemistry has complex materials which require students to comprehend prerequisite concepts before mastering complex concepts. This research aims to develop a Structured Essay Diagnostic Test of Chemistry for acid-base titration material that fulfils good criteria as an instrument for identifying misconceptions, learning barriers, and assessing student learning outcomes. The research procedure consists of 3 stages: determining the content, obtaining information about students misconceptions, and developing a diagnostic test. The SEDToC instrument was tested for validity and reliability. The SEDToC was validated by four educational chemists and high school chemistry teachers. Which was concluded that the SEDToC instrument is valid, and reliable in the very high category. Analysis of the difficulty index of the SEDToC instrument obtained 10 items in the easy category and 18 questions in the difficult category. The analysis of the discriminatory power of the questions was obtained that 6 items were in a bad category, 18 questions were in the sufficient category, three item was in a good category and one item was in a very good category. The results of the study using the SEDToC instrument for acid-base titration materials proved that the SEDToC instrument was able to assess student learning outcomes, identify misconceptions, and material inhibiting students.

Abstract

The concept is an understanding of an individual or a group of people who is expressed in the form of a meaning that produces knowledge. Misconceptions of students that appear continuously will interfere with the formation of scientific conceptions and can affect student learning outcomes. Therefore it is necessary to analyze the misconceptions of students. One of the diagnostic tests that can be used is a two-tier multiple choice test or known as a two-tier multiple choice, the first level is the question being tested while the second level contains the reasons for the answer to the first level. This study aims to analyze misconceptions and determine the percentage of students' misconceptions on hydrocarbon material using descriptive methods. The subjects were 27 students of class XI IPA 2 in SMA Pertiwi 1 Padang. The research instrument was a Two Tier Multiple Choice diagnostic test by dividing students' conceptual understanding into the categories of conceptual understanding, misconception, and conceptual misunderstanding. The results showed that the percentage of students' conceptual understanding in the concept understanding category was 31%, misconception was 36%, and did not understand the concept by 34% on hydrocarbon material. Students' misconceptions on hydrocarbon material at SMA Pertiwi 1 Padang were categorized as moderate. Konsep merupakan pemahaman individu atau sekelompok orang yang diungkapkan dalam bentuk pengertian yang menghasilkan suatu pengetahuan. Miskonsepsi peserta didik yang muncul terus menerus akan mengganggu pembentukan konsepsi ilmiah dan dapat mempengaruhi hasil belajar peserta didik. Oleh sebab itu perlu dilakukan analisis miskonsepsi peserta didik. Salah satu tes diagnostik yang dapat digunakan adalah tes pilihan ganda bertingkat dua atau dikenal sebagai two-tier multiple choice, tingkat pertama merupakan pertanyaan yang diujikan sedangkan tingkat kedua berisi alasan atas jawaban pada tingkat pertama. Penelitian bertujuan untuk menganalisis miskonsepsi dan menentukan persentase miskonsepsi peserta didik pada materi hidrokarbon dengan metode deskriptif. Subjek penelitian ini adalah peserta didik kelas XI IPA 2 di SMA Pertiwi 1 Padang yang berjumlah 27 orang.

Abstract

The COVID-19 pandemic has affected the education system in Indonesia, especially in the implementation of learning. Due to a lack of time, learning using a scientific approach does not go well. One way to overcome time constraints is to use discussion techniques in learning. Therefore, research is needed that aims to compare student learning outcomes using the Guided Inquiry and Discovery Learning learning models using the Buzz Group discussion technique on acid-base titration material. The research population was all students of class XI, IPA MAN 1, Kota Bukittinggi, consisting of 4 classes. The sample is determined by the random sampling technique. Class XI IPA 1, the experimental class, uses the guided inquiry model, and class XI IPA 2, the experimental class, uses the guided discovery model with the buzz group discussion technique. Posttest data collection was done in the form of essay questions, with a total of 65 questions. The results showed that there were differences in the average scores of the two experimental classes. Based on the results of hypothesis testing, it was concluded that learning using the guided inquiry and guided discovery models with the buzz group discussion technique differed significantly.
