Bridging the Gap: Making Biology Experiments Accessible in Under-Resourced Indonesian Schools

A striking moment for a high school student was witnessing DNA, previously only seen in colorful textbook diagrams, visibly floating as a white mass in a test tube after a simple strawberry extraction. Such impactful, hands-on experiences are often missing from biology education in many Indonesian schools.

Discussions with high school biology teachers frequently reveal a common challenge: a scarcity of laboratory equipment and materials. Some schools may have only three or four microscopes for a class of 30 to 40 students, and essential chemicals might only be purchased when funds become available. For schools located far from major cities, establishing a well-equipped science laboratory is a significant hurdle.

Consequently, many educators opt for the most feasible methods, which often means explaining concepts through lectures, textbook illustrations, or practical videos. Students end up observing experiments rather than conducting them themselves. This is particularly detrimental in biology, a science that thrives on observation, comparison, experimentation, and drawing conclusions from life phenomena.

Students who merely memorize terms like mitochondria, photosynthesis, cells, tissues, or DNA without direct observation struggle to develop a deep understanding. Conversely, simple experiences, like observing cells under a microscope or seeing DNA precipitate in a test tube, leave a lasting impression. These moments not only aid comprehension but can also ignite curiosity and a passion for science, potentially guiding students toward careers in scientific fields.

Addressing this issue, educators Rita Maliza and Dr. M. Idris have co-authored a guide titled "Dasar Biologi dan Bioteknologi: Dari Mikroskop hingga DNA." This book is designed as a workbook, not a supplementary theory text, providing step-by-step experimental procedures adaptable for teachers and students. Each activity includes implementation instructions and alternative adjustments for schools with limited resources, ensuring practical learning can occur without reliance on expensive equipment. The guide covers laboratory safety, microscope usage, animal anatomy, plant tissue culture, and microgreen production.
