This study investigated the development of the trainer mock-up innovation, as instructional material for teaching automotive technology students. It sought to answer for the level of acceptability of the Instructional Trainer in terms of functionality, usability, safety, and the level of quality of the Instructional Trainer in terms of content. This research study made use of developmental study mixed Method Design. This involved the mixing of qualitative and quantitative data also called Convergent parallel design as proposed by Creswell & Clark (2011). Convergent parallel design is a collection of data both qualitative and quantitative strands of the research performed independently, and their results are brought together in the overall interpretation of the gathered data.

The Functionality mean rating as perceived by the experts, showed a remarkable accuracy and consistency of the instructional trainer as it met the curriculum alignment of the automotive program having a mean of 4.9 or “extremely agree”. The researcher opted to get some feedback from the experts of this field to focus more on the functionality and usability of the prototype. Feedback from the experts about the functionality of the prototype was summarized in Table B below. As reflected in the table, all items obtained 4.9 mean score which is interpreted as “Extremely Agree”. The findings connote that the experts discerned the instructional trainer as a valuable instructional material in the teaching-learning process. Such high rating of the trainer could be linked to the completeness of the components where students could also familiarize and enhance their skills in automotive which are practical useful in unravelling practical problems especially in school. It also has a provision for developing students Automotive Servicing National Competency III (NC-III).

The experts’ evaluation on the safety features of the instructional trainer revealed as “Extremely safe” to use based on the average mean of 4.9. The findings revealed that the researcher was able to install all the components of the trainer properly and promoted safety for both the instructional material and the user. The results of this study was highly acceptable in terms of functionality, mobility, safety, and maintainability with a general weighted mean of 4.83.

As to evaluation on the level of quality of the instructional trainer module, the content aspect obtained 4.9 average mean which is interpreted as “Extremely Agree”. The findings revealed that the module developed could improve the quality of learning of the students, as it supports the teaching strategies as well.
