ABSTRACT
The study determined the effectiveness of Computer Aided Design (CAD) software on the drafting performance of students under the Department of Engineering Technology. The researcher opts to identify the problems on the students’ output using Computer Aided Design (CAD) as production tool, specifically on the Computer Aided Design software features, the effect of using Computer Aided Design software onto students’ performance in drafting such are: lack of equipment, facilities and materials, financial supports, and the student-respondents’ productivity.
The gathering of data underwent a process which was devotedly observed by the researchers to ensure that proper procedure has been meet in the course of investigation. Due to the limited access on the target number of respondents, the study is delimited to all graduating students under the Department of Engineering Technology and Home Economics of MSU-Lanao National College of Arts and Trades during the academic year 2020-2021. The researchers utilized self-made survey questionnaire, which consist of two parts; the part one is the respondents’ profile and the second part is the problems on the effectiveness of Computer Aided Design (CAD) to the respondents’ performance and output. The instrument was contained thirty (30) items.
The study used a mixed methods research design. The use of a survey-questionnaire is the sole instrument for the collection of study data to gain a greater understanding about the respondents’ problems on CAD software. A follow-up interview from both respondents and instructors that concerned the productivity of the student-respondents has been made to supplement the results of the study. Moreover, the researchers used Frequency (f) and Percentage Distribution (%) and Mode as statistical tools.

INTRODUCTION
In this generation, technological growth is extremely high, the success of every graduate student in terms of employability is based according to the needs of industry which in turn impact the type of education required to prepare incoming professionals to inter in the industry. However, it is not just about what kind of advancement needs. Before computers came along to simplify the design process, drafters in both the architectural and engineering fields relied solely on their ability to draw by hand. Nowadays, there were many software that can be use in drafting, one is, the program Computer-Aided Design (CAD) which is a software frequently used by different types of designers, architects and engineers to create a 2D drawings or 3D dimensional models to visualize constructions and enables the development and modification.
In the study, researcher wish to determine the cause of drafting students’ problem in performing their activities using CAD. Though it is quite understandable that the challenges of using CAD for students include a lack of understanding of its functions, limited access to personal computers, equipment, facilities, lack of interaction, and difficult in carrying out instructions. Moreover, students do drafting and designs should be guided with the country’s legal basis; like RA 8293 and RA 10557, such according to Section 172 Intellectual Property Code, literary and artistic works refer to the original and intellectual creations protected from the moment of their creation. Therefore, it is essential to guide the students to avoid conflict accordingly while doing their school requirements in drafting.
Furthermore, the researchers also wish to address the teachers’ problem on teaching Drafting because of lack of knowledge of design processes and therefore have difficulties in teaching Computer-Aided Design (CAD) as it is clearly affecting the students’ achievement during performing their activities using CAD. Additionally, the main purpose of the study is to determine the effectiveness Computer-Aided Design (CAD) on the drafting performance of Bachelor of Science in Teacher Education Students.
METHODOLOGY
A mixed methods research design was utilized in the study. The design was used for collecting data, analyzing it and mixing both quantitative and qualitative methods to understand the research problem. The survey-questionnaire was used as an instrument for the collection of study data to gain a greater understanding about the respondents’ performance using Computer Aided Design application. Prior to the administering of instrument, pilot testing has been made to fifteen (15) non-graduating students selected through random sampling as respondents to validate the survey-questionnaire. Moreover, after retrieval of the instruments, a follow-up interview using an open-ended question to both respondents and instructors that concerned the productivity of the respondents to supplement the results of the study. Moreover, the gathering of data underwent a process which was devotedly observed by the researchers to ensure that proper procedure has been meet in the course of investigation. The results of data collected were then submitted to statistician for treatment after which the data were interpreted. Using frequency (f) and percentage distribution (%) and mode as statistical tools of the study.
Due to the limited access on the number of target respondents, the study is limited to all thirty-two (32) graduating students taking up Bachelor of Science in Engineering Technology and Home Economics. The researcher utilized self-made survey questionnaire, which consist of two parts; the part one is the respondents’ profile and the second part is the problems on the students’ performance and the effectiveness of Computer Aided Design (CAD) as Drafting Production Tool. The part two also contained a total of thirty (30) items.
