Assessing preservice' higher order thinking skills (HOTS) in science and mathematics is essential. Teachers' HOTS ability is closely related to their ability to create HOTS-type science and mathematics problems. Among various types of HOTS, one is Bloomian HOTS. To facilitate the preservice teacher to create problems in those subjects, an Android…

This study aimed to develop a two-tier light concept test to identify student concept understanding of light. The development of the test was carried out through the content validity, construct validity, and reliability test stages using the Item Response Theory (IRT). The sample consisted of 81 students during the second semester at five…

Electronic teaching materials have an important role in improving the quality of learning, making learning more interactive, and making the learning process more flexible and productive. The development of the increasingly sophisticated era, technology, information, and communication have also developed and have an impact on learning media,…

Identifying a student's mental model is important for understanding scientific concepts. Dispersion and polarization are the sub concept of physics that studied in high school on light waves concept. This study aimed to develop dispersion and polarization conceptual inventory (DIPOLCI) to identify students' model mental using Rasch analysis. The…

An instrument to access the current situation of the application, knowledge, as well as attitude towards STEM education, is necessary. This research aimed to design and develop a valid instrument that can be used to assure the quantitative degree of…

Alternative conceptions become obstacles in physics. However, it is difficult to find instruments that can identify students' alternative conceptions, especially in gases kinetic theory (DIGaKiT). The purpose of this research was to development of diagnostic instrument of DIGaKiT in identifying students' alternative conceptions by Rasch analysis…

The challenge of accurately assessing critical thinking in physics education, particularly on topics like work and energy, remains a key issue for educators. The current study aims to address this challenge by exploring students' critical thinking abilities using two-tier test data analyzed through the Rasch model. Data were collected from…

Electronic student worksheets (e-worksheet) are needed as alternative teaching materials in learning. This study aims to produce teaching materials in the form of e-worksheet based on Search Solve Create and Share (SSCS) Islamic context to improve science process skills on class XI excretory system material that is worthy of the results of…

In the 21st century, Indonesian education must generate life skills for dealing with the era of society 5.0.
