Looking at Electrochemistry through a Concentration Cell: A High School Laboratory Activity Integrated into a Data Access System Explored with Preservice Chemistry Teachers

Integrating experimental activities with technological advancements and investigative pedagogies holds promise for fostering multifaceted development of chemical knowledge acquisition and innovative pedagogical methodologies for preservice teachers. This research evaluates how a laboratory activity on electrochemical concentration cells incorporating the Arduino system and implementing a Prediction-Observation-Explanation strategy improves chemical knowledge among preservice teachers. The study used a pretest assessing knowledge of galvanic cells, followed by evaluative questions during a course for preservice chemistry teachers. Preservice teachers had the opportunity to reflect on the module by commenting on issues related to implementing the activity and integrating the Arduino system. Difficulties are associated with understanding electrochemical cells and implementing the POE pedagogy. The study’s results provide a basis for comments on the activity’s adaptability and efficacy in the classroom and incorporation into a preservice teacher education curriculum.
