Usability and educational impact of IndagApp: A virtual tool for inquiry-based science learning in secondary education

Abstract

This study evaluates the effectiveness and usability of IndagApp, a 3D application designed to support inquiry-based science education across different secondary education levels in Spain. The sample comprised 82 students from a public school, including first-year and third-year secondary education students, and first-year baccalaureate students. Using app usage metrics, student performance was assessed through various error types related to hypothesis formulation, variable selection, simulation tasks, and question interpretation. Additionally, the Spanish version of the computer system usability questionnaire was employed to evaluate user satisfaction. Results indicate a general improvement in inquiry skills with educational progression, as reflected by decreasing error rates in most app metrics. Usability scores were generally positive, with high ratings in overall satisfaction, system usefulness, and information quality. IndagApp proves to be an effective and user-friendly tool for fostering scientific inquiry competencies in secondary education, supporting diverse learning needs and promoting engagement through structured digital inquiry experiences.
