The Development of Diagnostic Test Instrument for Verbal Representation Ability in High School Physics Learning

Abstract

Verbal representation ability is an important part of learning physics at school and is also useful for adapting to the environment. The verbal representation ability is also a need for education in the 21st century, so having this ability can help students to understand the physics language, physics quantity, and physics concepts. This research purposes to determine the feasibility of developed test instruments in terms of validity and reliability. The test instrument developed as a diagnostic test instrument in the form of multiple-choice with a total of 27 questions. The content validity analysis of the test instruments was carried out using the Aiken's V Coefficient. The validity and reliability of empirical evidence from the test instruments were estimated using Item Response Theory (IRT). The results of this research indicate that the developed test instrument is feasible to be used as an instrument to diagnose the verbal representation ability with valid results according to the Aiken's V coefficient between 0.81 to 1.00 and can be relied on with a reliability value according to IRT of 0.96 whereas developed questions are declared reliable according to IRT if used by students with abilities ranging from-2.0 to 1.9 on a logit scale.

Analysis of Needs for Elementary School Students' Diagnostic Instruments Development

“…This test can help identify students' levels of understanding, strengths, and weaknesses in various subjects, including mathematics, Indonesian, science, and others [17]. By using diagnostic tests, teachers can get a clearer picture of students' abilities and levels of understanding towards learning materials [18][19]. This information is precious in teaching planning because the teacher can adjust the learning approach and the material delivered to suit students' needs and level of understanding.…”

Development of Digital Diagnostic Test Instruments for Differentiated Learning Process in Elementary Schools

“…This test can help identify students' level of understanding, strengths and weaknesses in various subjects, including mathematics, Indonesian, science and others (Van Hooijdonk et al, 2023). By using diagnostic tests, teachers can get a clearer picture of students' abilities and their level of understanding of learning material (Tumanggor & Nirmala, 2021)(Acosta-Gonzaga & Ramirez-Arellano, 2021.…”

“…Differentiated learning is very important to ensure that each student can achieve maximum results according to their abilities and potential. In differentiated learning, diagnostic tests become an important tool for identifying the needs and abilities of individual students, so that teachers can develop learning plans that suit the needs and abilities of students (Tumanggor & Nirmala, 2021).…”

Thematic Analysis of Indonesian Physics Education Research Literature Using Machine Learning

“…Performance tests are designed to measure diverse forms of students' performance on physics learning, including cognitive test [97], higher order thinking skills (HOTS) [95,158,159], critical thinking skill [160], representation [161][162][163][164][165][166], data literacy [167], digital literacy [168], science process skills [169,170], problem solving skills [171,172], inductive thinking [173], visual literacy [174], communication skills [175], analytical thinking skills [176], and scientific literacy [177]. Moreover, several diagnos-tic tests are also established by the Indonesian PER authors to detect potential students' misconceptions [178][179][180][181][182], lack of representation ability [183][184][185], lack of higher order thinking skills (HOTS) [186], lack of critical thinking skills [160], lack of problem-solving skills [184], lack of data literacy [187], as well as the lack of understanding throughout astronomy class [188]. On the other hand, one can argue that this topic seems to be similar to the other extracted topics currently discussed.…”
