Abstract

This study reports on creating and validating a Guided-Inquiry STEM Laboratory Worksheet designed to teach Acids and Bases to Grade-12 STEM learners. Addressing the demand for engaging and practical instructional tools, the research utilized a quantitative design within a Research and Development framework, guided by the Input-Process-Output Model. The development process included conducting a pre-survey for needs assessment, drafting the worksheet, integrating advisor feedback, and subjecting the material to expert validation. Expert evaluation yielded an overall mean score of 3.76 (SD = 0.43), confirming the worksheet’s validity and high quality. Classroom implementation with Grade-12 STEM students further demonstrated strong acceptability and favorable perceptions among students and teachers. Consequently, the study endorses the adoption of the Guided-Inquiry STEM Laboratory Worksheet in teaching chemistry for both Senior and Junior High School STEM programs, while emphasizing the importance of ongoing evaluation, encouragement of student inquiry, integration into instructional practices, and future research.
