Background: Dialogue between the teaching profession and researchers regarding pedagogical strategy is sometimes problematic. Pedagogy research may benefit from incorporating research methods that can investigate teachers' and pupils' interpretations. Purpose: This research expands the Pedagogy Analysis Framework (Riordan, 2020) by explaining in…

This study aimed at determining the category and analyzes the mental models of the students from three senior high school clusters (low, medium, high) on the solubility and solubility product topic, knowing students' opinions on chemistry subject, knowing learning methods and assessment that teacher used in solubility and solubility products…

The French natural philosopher Henri Victor Regnault (1810-1878) was one of many researchers who contributed to the development of the thermometer in the 19th century. In this paper, we use an example from Regnault's work to explore how the history of thermometry can provide a context for teaching upper-secondary chemistry students about the…

Fostering methods that promote learners' conceptual understanding is crucial for better performance in science subjects. This study investigated how teachers of physical sciences perceive the utilization of Concept Cartoons as a formative evaluation tool. Ten Grade 11 teachers selected from secondary schools in the Nelson Mandela Bay district of…

Modern, student-oriented teaching can be characterized by the promotion of autonomy and interest. In the school subject of biology, it is necessary to focus on different ecosystems from different aspects. One ecosystem that has hardly been considered in biology didactics so far is the UNESCO World Heritage Wadden Sea. Therefore, this study…

We present a new secondary school teaching method of quantum uncertainties of two-state systems. Intending to be a material teachable in schools, only two-state systems described by real numbers can be considered. An elementary argumentation based on school statistics leads to the identification of the uncertainty of a physical quantity in such…

To make sense of our interconnected and algorithm driven world, students increasingly need proficiency with computational thinking (CT), systems thinking (ST), and computational modeling. One aspect of computational modeling that can support students with CT, ST, and modeling is testing and debugging. Testing and debugging enables students to…

Titration is an important experimental skill that every chemistry educator and learner must master. Titration is often the method of choice in the science laboratory courses in secondary and postsecondary schools. During acid-base titration, chemistry learners are always told about salt formation. However, a practical visualization of the salt…

About 30 years ago I taught a series of summer enrichment programs for high school physics teachers, using funding from the Howard Hughes Medical Institutes. I deliberately chose teachers from smaller cities and towns who were unlikely to have contact with other physics teachers. One of my more interesting teachers came from a rural area in a far…

A didactic sequence is proposed using an infrared puzzle and a didactic questionnaire for the teaching-learning of infrared spectroscopy at the upper secondary level. The didactic sequence that was designed was implemented in person in the subject of Chemistry IV at the high school level, corresponding to the sixth semester of the curriculum of…

In the context of the current COVID-19 pandemic, we deem of importance the identification of what content is privileged in secondary schools around health and disease. From our point of view, a relevant task is to accompany science teachers in their transit from teaching information to be evoked to teaching knowledge on that content that enables…

We investigated the effect of short-term teaching (3 weeks) using image analysis on gymnasium/secondary school students' (ISCED3A) skills (science process skills, SPS) and knowledge using Fiji (ImageJ) software. The theoretical teaching was combined with IT-based education (measurement of the area or signal intensity on photos from scientific…

Effective organic chemistry instruction necessitates an adaptable approach that accommodates varied learning styles and improves students' comprehension of concepts. To attain this goal, teachers may employ visualization, molecular modeling, and interactive software to explain three-dimensional structures and spatial interactions. Thus, the…

The way high school chemistry curricula are structured has the potential to convey consequential messages about knowledge and knowing to students and teachers. If a curriculum is built around practicing skills and recalling facts to reach ''correct'' answers, it is unlikely class activities will be seen (by students or the teacher) as…

Most chemistry instruction and assessment lie in the symbolic domain of Johnstone's representational levels, despite years of chemistry education researchers calling for increased emphasis to be placed on the molecular or particulate level of chemistry. Without a deep understanding of the particulate nature of matter and molecular-level…
