Abstract:
: This study evaluated the effectiveness of Digital-Alternative Microscopy (DAM) technology as a practical learning tool in Developmental Biology among BS Biology students at Palawan State University. Using a sequential-exploratory mixed-methods design, approximately 50 third-year Biology students were assigned to control and experimental groups through convenience sampling. Data were collected using a validated 60-item pretest-posttest instrument and a perception survey consisting of Likert-scale and open-ended questions. The control group utilized conventional compound microscopes, while the experimental group used DAM technology during laboratory activities. Results showed learning gains in both groups, with mean gains of 4.20 and 3.20 points for the control and experimental groups, respectively. The Mann-Whitney U test indicated a no significant difference in posttest scores (p = .059). Wilcoxon Signed-Rank Test results revealed significant improvements within both groups (p < .001), demonstrating the effectiveness of both laboratory approaches. Qualitative findings showed that although students initially had limited familiarity with DAM technology, they perceived it as easy to use, convenient, engaging, and effective for basic microscopy tasks. Despite challenges related to image clarity, alignment, and fixed magnification, students generally accepted DAM as a practical alternative for laboratory learning. However, many still preferred conventional microscopes for detailed observations. Overall, DAM technology shows potential as an accessible supplementary tool for microscopy instruction in Developmental Biology. Recommend further that administration support the procurement, development, and scaling of alternative microscopy tools like DAM, particularly in institutions with limited laboratory resources, and incorporated DAM Technology into laboratory manuals and instructional guides for Developmental Biology and related courses.
