Development and validation of high voltage and electric propulsion worktext for Marine Engineering students [manuscript] / Reynaldo P. Ongoco.

Include bibliographical references.

The study focuses on the development and validation of a worktext in High Voltage and Electric Propulsion during the Second Semester, Academic Year 2017-2018. The study made use of a descriptive research. The researcher had undergone different processes for this research: planning, designing, development, and evaluation. The data gathered was analyzed with the use of the following statistical tools: Frequency count and percentage was employed to describe the profile. Mean and corresponding descriptive equivalent was used to describe the development of worktext in terms of objectives, content, format, language and style, usefulness, and the availability, usability, and adequacy of equipment. Both the marine and electrical engineering instructors considered the areas of validation to be acceptable. There is no significant difference in the overall validation of the marine engineers and electrical engineers on the worktext. The null hypothesis of no significant difference is not rejected. This indicates that both marine and electrical engineering students concur that the work text is indeed acceptable. There are no significant difference between marine engineers and electrical engineers on their validation of the work text in terms of objectives, content, format, language and style, and usefulness. However, in terms of availability, adequacy, and usability of equipment, electrical engineers have significantly higher mean ratings than marine engineers as suggested by the significant t-value of 2.28. Hence, the null hypothesis of no significant difference is rejected in this specific area. Likewise, the findings of this study brought about implications for both theory and practice regarding the usefulness and practicality of work text in classroom instruction and the teacher devising the modules.
