Implementation and Perceived Effectiveness of Inquiry-Based Learning Strategies in Science

This study examined the implementation and perceived effectiveness of Inquiry-Based Learning (IBL) strategies in science among teachers and students in five public junior high schools in Panabo City, Davao del Norte. Anchored in Constructivist Learning Theory, Social Constructivism, Progressive Inquiry, and Cognitive Load Theory, it employed a quantitative descriptive-correlational design. Respondents comprised 31 Science teachers selected through total enumeration and 100 Grade 10 students selected through purposive sampling. Data were collected using validated researcher-developed questionnaires and analyzed using descriptive statistics, Pearson correlation, and independent samples t-tests. Teachers rated IBL implementation as Highly Implemented (M = 4.66) and its effectiveness as Highly Effective (M = 4.71), whereas students rated implementation as Implemented (M = 4.17) and effectiveness as Effective (M = 4.09). Significant positive relationships emerged between implementation and perceived effectiveness, with stronger associations in students’ assessments. Significant differences between teacher and student ratings indicated disparities in their classroom perceptions. The findings concerned student engagement, conceptual understanding, scientific inquiry skills, collaborative learning, and problem-solving abilities. The study proposed the INQUIRE+ Professional Development Program to strengthen Science teachers’ inquiry-based instruction through coaching, collaborative lesson study, reflective practice, and systematic monitoring and evaluation. It aligns with Sustainable Development Goal 4 (Quality Education) by supporting improved Science instruction and continuing teacher development. Its contribution to educational and institutional sustainability lies in promoting sustained professional learning, school-based collaboration, and evidence-informed instructional improvement across participating schools and varied local classroom learning contexts. Further evaluation of the proposed program is needed to establish its effectiveness after implementation.
