KEYWORDS Assessment tool, Go-Kart, Laboratory Manual, National Certificate II 1. INTRODUCTION One of the main objectives of the Bachelor of Science in Industrial Education program (BSIE) at the Don Mariano Marcos Memorial State University is to produce effective and globally competitive teachers as catalyst of change. As [40] said it focused on development of various knowledge, skills, and attitudes among the students. [13]said that teaching is the most important factor in cultivating student performance. However, many academicians see themselves primarily as experts in their discipline and hold content-oriented starts of teaching. It can then be difficult to motivate them to implement forms of teaching combining active students’ engagement, even though there is evidence for the effectiveness of such form of learning. Competencies are components acquired through formal and informal training’s. The traditional teaching method emphasizes the transmission of knowledge only. [5]Argue that “addressing the opportunity gap that has allowed inequalities in resources to deprive many students of needed opportunities to learn” as key to educational improvement. It is the ethical responsibility of the educational technologist to make every attempt to encourage and coordinate efforts to empower all students with the required digital skills and access to any device (mobile or stationary) with the needed connectivity so that they may cross the digital divide.
Mechatronics and Applications: An International Journal (MECHATROJ), Vol. 2, No.1 94 Innovative and dedicated automotive technology instructors as cited by [43] are selected to exploit the classroom environment as resource for learning’s,a process whereby an individual or a firm “acquires, creates, and disseminates new knowledge” by combining and recombining different pieces of knowledge into something new. Innovative teaching is a necessity for all teachers in order to meet the educational needs of the new generations. However, teachers’ competency for innovative teaching is a key factor influencing innovative teaching performance. [31] made a case study on Innovation of Automotive Sector of the Philippines. He found out that having awareness of the importance of technology and upgrading, some of the automotive firms are not able to translate this awareness into other technology activities. The case study aimed to provide background of the automotive sector of the Philippines and to understand the challenges being faced by automotive firms (assembler and manufacturer) n terms of innovation. In relation to innovation theory [35] states that patent system is second policy instrument of technological selection. The Patent system defines property right which supports the incentive for technological innovation. Patent system with limited scope promotes technology and knowledge diffusion. Technology-based innovation include forms such as (a) product innovation, (b) industrial research and development, and (c) technology transfer through imitation and improvement. Innovation drives economic growth. But what fuels innovation? As productivity grows, so does the economy. In the same vein, this study was conceptualized to innovate the GoKart machine The preceding statements encourage this researcher to contribute his share in the drive to economic growth through innovation--- the development of Go-kart with enhanced feature.[14] The use of innovation is useful in teaching learning process. For instance, the impact of computer simulation on the performance of 65 grade 11 learners in electromagnetism in a South African high school in Mpumalaga province revealed that the learners did not use the simulation individually, but the teachers used them as an interactive demonstration tool to effect better learning. According to [18] shortage of instructional materials device and equipment affects quality of education in technology. [4] cited on the effect of group project method on students’ academic achievement in car battery system in basic technology. It revealed in her study that there is significant difference in posttest academic achievement taught with group project method (GPM) and taught with conventional learning method. [31] cited the study of [2] who mentioned that small numbers of assemblers have access to best industry practice and state of the art technology while larger part manufactures are most small, medium enterprise have low technology levels and face problem of limited capital and lack of skilled workers. In industrial education system, the technological progress will cause the maladjustment of the manpower supply and demand. As a result, the industrial education should head for the directions of high-qualitative life, technology progress, productivity upgrade, manpower requirement, economic development, and modernization to greet the epoch making approach of the high-tech age as cited by [31]. According to [43] modern automotive technology changes rapidly fast and appears as new technology on a car, which instructors must be following as technology changes. The efficiency of learning need to propose in material package and the efficiency tools for self-study is computer. Because the learner can study every time, everywhere, and everyone. It is easy to access through the learner by networking.
Mechatronics and Applications: An International Journal (MECHATROJ), Vol. 2, No.1 95 A study on the blended learning is also important as it incorporates blended learning models, which link to elearning methods with practical sessions on hardware equipment. Go-kart or karting was born from United States in 1950s, where the engine was taken from discarded lawn engine. Go-kart is a driving and racing miniature, skeleton frame, and rear engine automobiles. Gokart is a nonpopular sport previously. Today it has become one of the most popular sports by multiple group of age as mentioned by McAuley (2008). This study aimed to develop and use go-kart not for sports racing but for instructional purposes. Based on the findings, the researcher prepared and validated a laboratory manual that integrates different topics like steering calculation, wheel alignment, brake adjustment, lighting circuit and engine mechanical system. [23] in his work a detailed methodology of virtual design and testing has been presented, to evaluate the dynamic performance of Go-kart vehicle particular attention was paid to the understanding of the behavior of the structural frame, That the most important element in the determination of vehicle turning performance. A validated finite element model once validated has shown excellent capability to reproduce the frame structural behavior. [26] presented a paper which aims to increase the factor of safety of the Go-kart chassis, which is designed keeping in mind the rules imposed by Go-kart Design Challenge 2015. Theoretical calculation are carried out which have been realized through several analysis. During the impact analysis, the chassis meet the required factor of safety. In order to enhance factor of safety a computer aided design model was altered marginally such it meet safety requirements. In the study 0f [27], mechanical engineering technology students with interest in automotive technology to design and build electrically powered Go-kart to learn product design, prototyping, and manufacturing. The outcome of such learning experience from the project can be expanded to interdisciplinary project oriented course for engineering students to enhance their learning experiences. [28] worked on a detailed methodology of virtual design and testing has been presented including the reason of using materials for fabrication of the chassis and axle. The materials used in the chassis is chromally quality 4130 with diameter of 30 mm. Steering system used is Ackerman steering system with tie rod. [29] researched on static analysis of go-kart. [33] fabricated a go-kart that included lathe work, drilling, milling ,grinding. The design is chosen such as the kart is easy to fabricate in possible aspect. Design process of the vehicle is based on varios engineering aspect depending upon safety and ergonomics, market availability, cost of components and safe engineering process. Today’s go-kart frames are made from lighter iron and others which are more durable and can absorb more vibration even if it has no suspension. The design and fabrication of a go-kart vehicle gives special attention to improvement of suspension system and dynamics over the previous models, noting the nodal analysis of previous models and the points of review and limitations in old models. New designs try to eliminate the defects of old designs and also implementing the positivity of old designs in the new ones. Go kart is the simplest form of motorsport but for the author is used for instructional purposes. All go karts such as sprint kart, road racing, indoor karting and speed way karting look alike .
Mechatronics and Applications: An International Journal (MECHATROJ), Vol. 2, No.1 96 Narrow kart are from 24” to 25” and wider Kart are measured from 27” to 28”.With my design I will used 24” chassis frame measured 12” at the center and I will use pipe as a frame. Go-Kart manufacturer started to do more research and development. To improve the Go Kart in terms of chassis design, speed , braking system and transmission system. [8] model and analysis of a regular kart structure subjected to real efforts using the Finite Element Method. The researcher made use of the model made by Fray and Santos as a guide. This paper describes the development and result of the design, fabrication, and evaluation of the go-kart and the laboratory manual for assessment tool. [14] cited the terms “design, engineering, and technology” ( DET).My present research is through this idea on design engineering is my pattern. Scientific ideas within the framework of their existing knowledge are the starting point of cognitive constructivism (Wieman, Adams, & Perkins, 2008). To accomplish this process, learners must be motivated to actively engage with the content and must be able to learn from that engagement. Interactive computer simulations can meet both of these needs Eniekenemi, & Taiwo (2016) said that students taught with experiential learning strategy performed well than those taught with conventional lecture strategy. It was recommended that teachers of automobile technology should exposed and allow students to face more practical work experiences. [25] on the effect of group project method on students’ academic achievement in car battery system in basis technology, Design is concept usually considered in the context of applied arts, engineering, architecture and other creative endeavor. To design refers to the process of originating and developing a plan for a new object such as machine product, structure, system or component. According from Italians.com, normally a designer requires to consider the aesthetic , functional, and many other aspect of an object or process, which usually requires considerable research, thought, modeling, interactive adjustment, with these concept the researcher used this as guide. Suryawanshi (2014) designed and simulated a producer gas carburetor, due to the increasing energy demand to keep the sustainable development, there is a major need for utilization of alternative energy source in order to meet stringent emission regulation. He use design with CFD in analyzing combustion process. The foregoing concept inspired and encourage the researcher to pursue this study to teach students along the core competency of automotive technology such as service wiring/lighting system, service engine mechanical system, service steering system and perform brake system servicing. [22] on Competency based education , a specialists, who are able to adapt to labor market and ready for new changes, for self-learning. The objectives of modern education in the new condition is intended to be focused not just fundamental knowledge but on the labor market and in the formation of practically oriented skills and competencies. [11] studied the effective practice for developing competency based learning models in higher education. Self -direction and being able to apply experiences in learning is a key tenetsof a competency-based learning. She cited Weise & Christensen (2014), whose works revealed that
Mechatronics and Applications: An International Journal (MECHATROJ), Vol. 2, No.1 97 competency-based programs do not measure time spent on task; learning is fixed; time is variable and pacing is flexible. Requirements and Procedures in Applying for Assessment and Certification (National Certificate (NC)/Certificate of Competency (COC)as stated in training regulation set by Technical Skills development Authority or TESDA are the following 1. New Applicant, 2. Renewal, and 3. Lost/Damaged Certificate. Technology and Livelihood Education (TLE) and Technical-VocationalLivelihood (TVL) Track Technology and Livelihood Education (TLE) and Technical-VocationalLivelihood (TVL) Track specializations may be taken between Grades 9 to 12. Specialization Number of Hours Pre-requisite Automotive Servicing (NC I) 640 hours Automotive Servicing (NC II) 640 hours Another issue is that there are data that go kart is being researched on the Philippines setting as a tool for educational purpose. The ideas on sustainability of instructional materials for technical-vocational courses prompted the researcher to conduct this research keeping in mind that the Go-kart would be a tool to enhance the learning potentials and dynamism of technology students. Further, the concept and principle of STEEP challenge the researcher stands for Social, Technical, Economical, Environmental and Political Analysis. In the conduct of this study, the researcher would consider the social, technical, economic, environmental and political aspect of the innovated Go-Kart. STEEP is used to identify the external forces such that it spots opportunity, implement appropriate practices, and break free old assumptions. Social factors includes current trend in society, life time trends, now a days Go Kart are used for social enjoyment or through community building to get out on boredom. Technological factors such as the manufacturing maturity, information system and consumer access to technology. It means that the go kart uses technology which is the used of a certain application like Internet Protocols. Environmental factors sustaining the environment by making a certain locality to become attractive in go kart an irregular land can be landscaped so as to attract costumers, this also make students to care for environment. Economic factors such as market demand and costumer preferences, the go kart will be used as an incomegeneration project for the College. Political factors include laws, property rights and patents. This means that in making the GoKart the researcher would consider the intellectual property rights of those who developed similar go kart.
Mechatronics and Applications: An International Journal (MECHATROJ), Vol. 2, No.1 98 The TAP (Technology Assessment protocol) is a policy analysis, usually undertaken by the DOST, to support decision making about technology or technological projects. It is design to anticipate the gaps and risk associated with technology transfer and utilization. The TAP involves three steps: (1).Technology pre-screening or identification; (2) Technology scanning and (3) technology validation. The above viewpoints imparted additional ideas and provided guidance and concept to this research. The aforementioned studies guided the researcher in designing, fabricating, evaluating then prepared and validated a laboratory manual for use on the four selected core competencies such as Service Wiring/Lighting System, Service Engine Mechanical System, Service Steering System and Service Brake System. 2.

RESEARCH DESIGN This study used developmental research design and descriptive-evaluative research design. Development design was applied in the first phase of this study, that is, the design and fabrication of the Go-Kart. [37] the purpose of developmental research is to design a new product to address specific need. Once the product is created, it is tested, evaluated, and revised until specified criteria of quality and effectiveness are satisfied. The researcher made innovation to the existing design to come up with the new Go-Kart design. The innovative design included additional part.
Mechatronics and Applications: An International Journal (MECHATROJ), Vol. 2, No.1 100 Likewise, descriptive-evaluative design was used because the study gathered and described the data and characteristics of what was being studied. According [39] descriptive research design is a method which involves observing and describing the behavior of a subject without influencing it in any way. Descriptive research design is appropriate in this study because it involves a collection of quantitative information that were tabulated along a continuum in numerical form.[9} state that descriptive research involves gathering data that describe events and then organizes, tabulates, depicts, and describes the data collection. It often uses visual aids such as graphs and charts to aid the reader in understanding the data distribution The descriptive–evaluative phase in this study involved the gathering of data using an appropriate questionnaire, then analyzing the data to determine the level of technical performance, economic/financial feasibility, environmental, political and social acceptability of the developed project. 3.1. Materials and Procedures The materials for the fabrication of the Go Kart were purchased from hardware stores and automotive supply stores in the locality. It can be gleaned from Table 1 that the materials used to fabricate the parts of the Go-Kart were inexpensive and affordable yielding the total cost of Php 8.456.00. Table 1 shows the 22 items, including their corresponding quantity, description, and unit and total cost. Meanwhile, the machine shop labor cost, which was based on the current labor cost in the locality, was Php 2,000.00. Figure 1 shows the step-by-step flow in the fabrication and assembly of the Go-Kart. The diagram shows that the work started with the fabrication of the frame. Next was the assembly of the steering system that composed of knuckle, tie rod, ball joint, steering shaft, steering column, and steering wheel. Then, the engine was mounted with fuel tank, carburetor, and oil tank. Then, the axle and wheel chains and gear were mounted; the axle was mounted by two pillow blocks. Then, the brake assembly, which composed of brake pedal, brake cable, brake shoe and brake drum, was mounted.

Mechatronics and Applications: An International Journal (MECHATROJ), Vol. 2, No.1 108 4.6. Environmental Soundness Table 4 shows that the environmental soundness of the Go Kart was highly acceptable ( 4.15). This indicates that the Go-Kart does not pose threat to environmental sustainability form hazardous effect to plants, animals, and human welfare nor do raw materials pose danger to biodiversity. It can be inferred from the findings that the development of the Go-Kart, from beginning to end, is in essentially harmony with the school environment, where it would be used. It does not cause pollution. It means that the environment--with all its complexity, essential cycles, and relationships--remains intact, functioning, and healthy. Further, the finding implies that the goKart was developed without generating environmental burdens.It uses resources in a sustainable manner, that is, without destroying the living things around. Rather, it lends support to the rationale for sustainable development and the importance of meeting the needs of the present.The rise of unexpected threats from its development and use is beyond reason. The finding supports that of [30] who stated that the Go-Kart environmental impact depends on the acceptance of the community. Table 4.

They were informed, consulted in a transparent way on the economic/financial benefit of the project. Moreover, this finding implies that the Go-Kart can be adopted and used for the benefit of the end-users, as claimed by [30]. 4.9. Overall Assessment of the Go Kart Table 7shows the overall assessment of the Go Kart. The overall mean rating of 4.25 indicates that the Go-Kart was in very good condition as a tool for Automotive NCII. It can be gleaned from the finding that, among the indicators, “social acceptability” ranked highest (4.35) and “economic/financial feasibility” was second (4.30). Meanwhile, “environmental soundness” ranked last (4.15) but still described as very highly acceptable. Table 7. Summary Assessment of the Go-Kart ( n=10) Indicators Experts End-users Overall DR 1.

This indicates that the Go-kart can supplement knowledge and skills. The overall findings implies that the Go-kart can be regarded as utility model for experiential learning. Innovative teaching like the development of Go Kart is important for the present and future of education to help students to reach their full possibilities. Higher education serves the long term intellectual needs of students. For example, new materials may be provided by teachers to help the students to gain new insights, or new channels of intellectual stimulation maybe opened up, students’ essential and creative thinking power may be enhanced. The Go-kart would be instrumental in sustaining the learning potentials and dynamism of technology students. 5. CONCLUSIONS Based on the findings, the following conclusions were drawn: 1. The development of the Go-Kart was consistent with the design and plan of activities. 2.
