Traditional teaching methods in chemistry have been insufficient in helping students master problem-solving and conceptual understanding across the three levels of chemical representation: macroscopic, submicroscopic, and symbolic. Innovative strategies are needed to address these challenges and improve learning outcomes. This study evaluates the feasibility, practicality, and effectiveness of a non-routine learning strategy as an innovative approach to teaching chemistry.

Symbolic expressions are essential resources for producing knowledge, yet they are a source of learning difficulties in chemistry education. This study aims to employ social semiotics to analyse the symbolic representation of chemistry from two complementary perspectives, referred to here as contextual (i.e., historical) and functional. First, the contextual account demonstrates that symbolism was introduced to represent compounds according to their elemental composition, to quantify chemistry, and to explain reactivity. Further to this, the functional analysis shows that symbolic expressions

The study was conducted to map the misconception pattern of chemistry prospective teachers who learned acid-base and argentometric titration. Further, it attempts to minimize misconception through a multiple representation model of learning chemistry with cognitive dissonance strategy. The first treatment was done on acid-base titration and the second treatment on argentometric titration materials. The multiple choice test with open reasons was administered to 30 undergraduate students. The finding shows that 28.6% students have the same pattern of misconception while learning in both of the c

The increasing number of positive cases of COVID-19 in Indonesia has prompted the Ministry of Education and Culture (Kemendikbud) to recommend online learning as an effort to reduce the spread of the virus. The use of new online learning technology is dominated by SMA / MA in big cities because of the financial capacity and availability of a digital learning system that is better than SMA / MA in remote areas. The problem currently faced is the unavailability of teaching materials oriented to the online learning process (e-learning) in accordance with the demands of the 2013 Curriculum and the

In the chemical education field, the Johnstone’s triangle represents three learning levels (symbolic, macroscopic, and molecular) needed for students. Afterwards, Mahaffy suggested a tetrahedron model based on this triangle, where the top represents the human element. Subsequently, Sjöström proposed a subdivision of the top into three other levels: applied chemistry, socio-cultural context, and critical–philosophic approach. These six dimensions of chemical knowledge will be examined in relation to the discovery of aniline, its chemistry and applications. The historical and epistemic aspects o

This paper is the third in a series of our works. We built a neural-symbolic system, named FGeo-DRL, to automatically perform human-like geometric deductive reasoning. The neural part is an AI agent based on deep reinforcement learning, capable of autonomously learning problem-solving methods from the feedback of a formalized environment, without the need for human supervision.

These three levels of representation are interconnected to form a meaningful understanding and students' mental model. The purpose of this study was to look at the mental models of students on acid and base topic taught using cognitive apprenticeship learning model.
