Mengevaluasi Level Pemahaman Konsep Hidrolisis Garam Peserta Didik Menggunakan Tes Diagnostik Pilihan Ganda Empat Tingkat

Abstract

The ability of students to understand and use concepts is the main key in scientifically explaining various chemical phenomena in nature. This ability develops relatively, often with the development of the learner level. This study aims to understand the level of understanding of the concept of salt hydrolysis of class XI high school students and chemistry students in the I, II, III and IV years and non-chemistry students with a total sample of 875 respondents. The instrument used in this study was a four-level multiple choice test. This diagnostic test combines the measurement of knowledge and reasoning with the level of self-confidence, as a reflection of the level of mastery of concepts. The data analysis technique used is quantitative, using SPSS 25 software, namely the non-parametric test (Kruskal Wallis test), comparing the significance value (Asmp. Sig) with a probability of 0.005. The results showed that the significance value of 0.00 was less than 0.05; That is, there is a significant difference in the level of understanding of the salt hydrolysis concept of students. The level of understanding of the concept of high school students is better than the first, second, third, and fourth year students in chemistry and non-chemistry students. These findings reinforce the story that although students have experienced learning experiences at a higher level, it does not guarantee the development of mastery of understanding the concept of hydrolysis

Rasch Modelling to Evaluate Reasoning Difficulties, Changes of Responses, and Item Misconception Pattern of Hydrolysis

“…The research instrument involved 30 items that measure the students' reasoning ability on the concept of hydrolysis. The instrument was in the form of multiple-choice test that was adapted from the previous study (Laliyo et al, 2022;Suteno et al, 2021), and developed by referring to the recommendations from Wilson (2005). Table 1 shows the conceptual map of reasoning of salt hydrolysis that involves ten levels of constructs.…”

Using Four-Tier Test to Identify Prospective Elementary Teacher Students’ Misconception on Electricity Topic

“…The four-tier test form provides more in-depth information regarding the level of confidence in the answer choices and answer choices as well as the suitability between the answer choices and the reasons so that the chances of guessing are very small (Ismail et al, 2015;Janah & Mindyarto, 2020;Maison et al, 2019Maison et al, , 2020Nurjani et al, 2020;Nurulwati & Rahmadani, 2020;Rahmawati et al, 2021;Ibnu et al, 2019;Suteno et al, 2021;Yang & Lin, 2015). Ismail et al (2015) in their research using a four-tier test diagnostic test to identify high school students' misconceptions about electricity, emphasized that the four-tier test instrument form is a development of the three-tier test form combined with a confidence rating on the reasons for answers so that the level of confidence is more accurate, for the answers and reasons for the answers.…”
