The main objective of this four-year empirical research project has been to develop the experimental design skills of 12-16 year-old Hungarian pupils in Grades 7-10 of junior high school through guided inquiry, using six chemistry experiment worksheets each school year. Group 1 (control group) and Group 2 follow step-by-step instructions, but…

Clathrate hydrates are attractive materials for education because they form from water and familiar compounds, such as carbon dioxide, and are relevant to novel technologies. In this study, an attempt to propose a laboratory experiment was summarized, which used carbon dioxide clathrate hydrate as an educational material with carbon capture…

This study investigated the strategies students in general chemistry and analytical chemistry courses used before and after instruction to solve a volumetric analysis problem in which the molar ratio was not 1:1. Questions like this have historically been very challenging for high school and undergraduate students. Student writing on open-response…

Resonance is a crucial concept in Organic Chemistry that enables both deriving chemical properties from molecular structures and predicting reactions by considering electron density distribution. Despite its importance for problem-solving and learning success, learners encounter various difficulties with this concept. Although prior research…

In the context of scholarly and scientific discourse, students often have to deal with graphic-visual modes of communication, which requires their ability to comprehend and utilize inscriptions, that is, scientific visual representations, to convey information effectively--what we call graphical literacy. Despite its pivotal role for training…

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…

Dimensional analysis is an algorithm currently in use in almost every chemistry classroom in the United States. Chemistry educators use this procedural tool in the classroom with the intention of providing students with a reliable method to solve many of the relatively simple math problems they encounter. The unintended consequence of using this…

In today's global economy, the origin of the food we eat is becoming more and more difficult to identify. Verifying the authenticity of products to protect supply chains is a complicated problem that requires a multidisciplinary approach. Chemical authentication of foodstuffs often includes a mass spectrometer detector; however, they are costly…

Human-driven carbon emissions have resulted in increased levels of dissolved carbon dioxide in the Earth's oceans. This dissolved carbon dioxide reacts with water to form carbonic acid, which impacts ocean acidity as well as the solubility of carbonate-containing compounds, with far-reaching impacts on marine ecosystems and the human communities…

The Case Study (CS) method is a teaching methodology based on constructivism and centered on students, which actively develops their learning. Through the study of a case, which can be a real or fictional story based on everyday life, the student is asked to solve a dilemma and thus is expected to develop higher skills. Through this systematic…

Escape rooms are making their way into the chemistry classroom as a learning tool. However, escape rooms require a large amount of preparation and setup, and they are only novel and exciting for a single play-through. For escape room games to be incorporated into multiple class periods, they must be streamlined for reuse. In this work, I introduce…

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,…

Recent advancements in large language models (LLMs) have shown potential in enhancing educational practices, particularly in technology-assisted learning environments. This study critically evaluates the reasoning capabilities of LLMs, such as ChatGPT, within the context of chemistry education. We designed targeted adversarial prompts that…

A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

Does invention belong in the chemistry classroom? This article attempts to answer this question by describing how invention education first took root in a chemistry class at Ridgewood High School in Ridgewood, NJ, and then expanded to other students with diverse interests to find a solution to two worldwide problems: satisfying the need for safe…
