Abstract:

Performing experiments in a laboratory setting is integral to understanding scientific concepts, particularly in fields like analytical chemistry where hands-on experience is paramount. However, traditional laboratory experiments can present various challenges, including limited access to equipment, safety concerns, and constraints on time and resources. Furthermore, an additional challenge arises when students arrive at the laboratory without having adequately revised the experimental procedures, potentially leading to accidents and compromising the quality of the learning experience. To address these challenges and enhance the learning experience, we developed a Teaching and Learning Mobile Application for Titration employing Augmented Reality (AR) technology. By leveraging AR technology, the application offers immersive and interactive experiences that simulate real-world laboratory settings, allowing students to engage with titration concepts and techniques anytime, anywhere, and without the need for physical reagents or apparatus. Additionally, the mobile application incorporates additional features including reference reading material for quick introduction to the titration process and some short stoichiometric calculation exercises, which complements student learning. To assess the effectiveness of the AR application, a user survey was conducted with undergraduate students. The student cohort was divided into two distinct groups: one comprising individuals utilizing the application, and the other consisting of those abstaining from its use. Feedback on the application features and its impact on practical skill learning was gathered through a combination of open-ended and rating questions. The results revealed a positive reception of the AR application, with most of the participants rating it as a valuable supplementary tool for practical learning of analytical chemistry. By providing a safe and accessible platform for learning, the AR application seeks to empower undergraduate students at Singapore Institute of Technology (SIT) to engage with analytical chemistry concepts effectively and independently. As an in-house tool the future directions include expanding the application to encompass a broader range of titration and chemical experiments, catering to diverse learning needs and facilitating comprehensive laboratory experiences across various domains of education. During the presentation, we will be discussing the features of the application and showcasing the application developed.
