Cardiovascular diseases are rampant across the country; it is said that uneducated individuals are at risk to the said health condition. There is an urgency to provide better health education to address and reduce the number of cases having cardiovascular diseases. Education is also facing a problem on how to teach the students on this topic particularly on how pulmonary and systemic circulation works due to limited resources, particularly in pulmonary and systemic circulation. Though schools only have traditional instructional materials, mostly textbooks and other printed materials are only available. Thus, this study aimed to develop an interactive 3D instructional material for pulmonary and systemic circulation known as Pump-in-a-Box, an intervention to aid the scarcity of learning materials for teaching pulmonary and systemic circulation intended for grade 9 students. This study uses descriptive-evaluative research design and utilizes the Learning Resources Management and Development System or (LRMDS) which is a set standard of DepEd for evaluating the features of the Pump-in-a-Box. For acceptability and suitability of the Pump-in-a-Box, the researcher adopted and modified a validated research evaluation tool. After developing the Pump-in-a-Box, survey questionnaires are given to experts to evaluate and validate the instructional material. Data for the Pump-in-a-Box suggested that it was able to pass the required criteria for the factors: content and manipulative. However, the general weighted average for factor errors was 15 points thus, it failed to meet and pass the said criteria. On the other hand, the acceptability of Pump-in-a-Box in terms of its design, durability, and functionality got a general weighted average of 4.77; the general weighted average for the level of suitability gained 4.78 points in terms of: structure of the model, delivery, ease of operation, and experience attained a high level of acceptability. The failure to meet and pass the criteria leads to revalidation of the modified model. Upon revalidation, the model garnered a perfect score for its acceptability and suitability among the experts which received a “Very High” descriptive rating, making the enhanced Pump-in-a-Box commendable after following the several suggestions of validators. The study concludes that the interactive 3D instructional materials for pulmonary and systemic circulation is suitable to utilize in education settings. The researcher recommends further improvement and incorporates Pump-in-a-Box in teaching pulmonary and systemic circulation for the improvement of the students' learning experience.
