Teaching biological molecules concepts in relation to how teachers adjust to the different challenges and how students understand and achieve good academic performance is what this research study aims for. The quantitative research approach with the aid of the researcher-made test questionnaire was utilized in this study. The data sample consists of forty (40) Grade 11 Science, Technology, Engineering, and Mathematics (STEM) students. The result showed a significant difference between the pretest and posttest scores. It was found that the low score was because the concept was introduced in junior high school but not in detail, not enough teaching-learning instructional materials, and the teaching strategy used does not fit all types of learners. Another factor may be the students forgot the topic due to the current pandemic situation. The result of the post-test was impressive, this time the students had knowledge about the concept and the students had activities to understand the lesson very well. The interventions used in the study like effective teaching strategies, using weekly learning activity sheets, and other interventions made the academic performance of the students’ increase. The positive output of the study suggests that teachers should improve their ways of teaching to relate to diverse types of students.
