Teaching techniques inventory for explaining gene, DNA, and chromosome concepts in senior high school

Genetics is a fundamental topic in Biology, yet its abstract nature presents challenges in the learning process. Effective teaching of genetics concepts requires appropriate instructional approaches to facilitate student understanding. The success of learning outcomes depends on various components, including teachers, students, learning objectives, content, teaching methods, and assessment strategies. The integration of suitable teaching techniques and instructional media is essential, particularly when addressing specific learning difficulties faced by students. This study employed a survey method with a qualitative approach to explore the teaching techniques used by teachers in delivering the concepts of genes, DNA, and chromosomes to 12th-grade students. The findings revealed that teachers implement 20 distinct teaching techniques, which are combined into 13 different instructional strategies to enhance student comprehension. This study provides teachers with insights into various teaching techniques to address the learning difficulties that students often encounter in understanding genetics.
