Within physics education research (PER), resource theory has proven to be a useful framework for investigating knowledge and learning and informing instructional design. To analyze learning over longer timescales and across cases, PER scholars must first identify and describe the resources activated within and across physics contexts and domains.…

Recently, the question of which version of content knowledge (CK) is suitable for pre-service teacher (PST) development has gained prominence in teacher education research. A version of CK argued to be appropriate for science PST development has been introduced and referred to as teacher-related science content knowledge (TerSCK). This CK version…

This study aims to evaluate students' ability to process the context information embedded in chemistry problems. To achieve this goal, a diagnostic measurement instrument was developed, comprising 28 short-answer items embedded in seven context-based chemistry tasks. Four hundred and ninety-three ninth-graders took part in the testing in Jiangsu,…

Learning is a continuous process involving teachers, students, materials, and the environment to achieve specific goals. One important aspect of learning is the use of learning media. This study develops a learning media in the form of a magazine on the human circulatory system and an inventory of antihypertensive medicinal plants in Sari Makmur…

A socio-scientific issue is one of the learning techniques used today, which uses various scientific sources to make students think scientifically to conduct a dialogue and discuss solving a problem. Various problems in socio-scientific are controversial, requiring reasoning, and ethical evaluation in the decision-making process. A conflict…

This three-paper dissertation systematically investigates the methodology issues related to using observational systems to observe, analyze, and interpret teachers' reformed teaching practices within the K-12 classroom context. Each paper contributes a distinct perspective to evaluate instructional practices accurately, consistently, and…

Interdisciplinary thinking is critical for equipping students to apply scientific knowledge and tackle societal challenges across various disciplines, which has been recognized as a key objective of twenty-first century science education. However, research on effective interdisciplinary assessment in secondary school science education is still…

Questioning is a critical strategy for science teachers to scaffold students' exploration and knowledge construction in inquiry-oriented science teaching. In science teacher preparation, open-ended questions asked by teachers are advocated as an advantageous strategy to prompt student thinking. However, insufficient attention has been cast on how…

As implementation of green chemistry into university-level courses increases, it is vital that educators have a tool to rapidly measure student knowledge of green chemistry principles. We report the development of the Assessment of Student Knowledge of Green Chemistry Principles (ASK-GCP) and evaluation of its sensitivity and effectiveness for…

Despite the importance of evolution to understand biology, there is significant evidence that many biology teachers have difficulties to successfully teach this topic. The purpose of this study is to describe procedures by which a paper-and-pencil instrument to assess teachers' pedagogical content knowledge for evolution (PCK[subscript evo]) was…

Scientific thinking constitutes a vital component of scientific competencies, crucial for citizens to adapt to the evolving societal landscape. To cultivate students' scientific thinking, teachers should possess an adequate professional knowledge foundation, which encompasses pedagogical content knowledge (PCK). Assessing teachers' PCK of…

In an effort to investigate the factors that lead to success in general chemistry, the Math-Up Skills Test (MUST) and common questions were used along with a student characteristic questionnaire. The MUST is a 20-item instrument to measure mathematics fluency, which is done without a calculator with a 15-min time limit. It has been shown as a…

Advanced clarification is an essential part of thinking skills relevant to students, which contains the ability evaluate, make decisions and make arguments. This ability is needed to prepare students to face the VUCA era. Clarity Learning Model (CLM) is a formulation of IBL, and the strengthening of reasoning abilities aims to improve advanced…

The aim of this research is to examine the effect of subject matter knowledge education (SMKE) on the pre-service science teachers' approach to error about plane mirrors. This study was conducted using developmental research and phenomenology designs, which are qualitative research methods. In the study, the data were analyzed with the descriptive…

The Enthalpy and Entropy in Dissolution and Precipitation Inventory (E2DPI) has been developed to measure student understanding of the dissolution of ionic solutes, aqueous precipitation reactions, and the enthalpy and entropy changes that accompany these processes. The E[subscript 2]DPI was designed using a mixed-methods protocol, such that the…
