The developed electrical multi-purpose table can be subject to any modification for the betterment of the product. The study recommended that a better and more effective design can be applied to the product. Any innovative design that could help to improve its usability to end user will be highly regarded. In terms of product appearance, the electrical multi- purpose table is open for improvement to address the possible inconvenience of the end user. The product can be customized to give costumer’s satisfaction (e.g. color, height, dimension etc. It was also concluded that the teachers and student respondents strongly agree on the acceptability of the developed product along with its functionality, usability, mobility, and safety, therefore it is recommended to use this in EIM laboratory room in all DEPED and TVI schools in the country.
Based from the generated data in this study, the following findings are given: 1. The process and development of the Electrical multi-purpose table applied the ADDIE model. It has five phases: Analysis, design, development, implementation, and evaluation. The materials used in developing the electrical multi-purpose table are plywood, metal frames such as angle, flat and tubular bars, and electrical and electronic materials. The Electrical Multi-Purpose Table has two main assembly, the table top and the leg stand frame. The construction started from the first part of the Electrical Multi-Purpose table which is the Table top. The Table top is almost the same as compared to an ordinary classroom table and other furniture table seen at home and in the market. The only difference in this tabletop design is that the bottom part of this is purposely designed as a wiring board and holds electrical wiring equipment and circuitry including CCTV module that EIM learners will be using during their laboratory activities.
The leg stand frame is the second stage and another assembly part of the electrical Multi-Purpose table and are responsible in carrying the weight of the entire product. The Leg stand frame of the table composed is of a fabricated tubular bar welded together according to its unique design and measurements to fit the mobility of the user. It has 6 sub parts namely, Rear leg, Front leg with adjuster, Leg Frame, stretcher, drawer with lock.
The third stages of the construction are the painting of the Electrical Multi-purpose table. This is done to give the table additional protection against corrosion, wear and tear and outdoor elements specially that the top of the table is made of plywood. The importance of this is that it will not only make the product look presentable and unique but this are intended to perform and last longer because of paint that provide a protective layer to the entire part of the product.Electrical Installation is the last stage of the construction process, this are installed after the paints are dry. The Face B of the Table top is where the electrical installation is made. This comprised of the main control unit, the electrical rough-in assembly, and the CCTV module assembly. 2. The electrical Multi-purpose table has many features that could provide end user to value this product. This product features are attributes that can be seen by the end user and considered as a condition or strategy to satisfy costumer of the product. This product features can be seen along the different variables including, Functionality, Usability, Applicability, Portability, Safety, and Efficiency. The features of the Electrical multi-purpose table along a) functionality reveals that the developed product is operational, easy to open and electrical circuitry are safely installed. b) usability was defined in this product as user’s friendly.
The product can be easily set to stand fit in the ground by adjusting the adjuster (bolt) at the edge of the table leg. And, can be smoothly open if to be used as demonstration or laboratory table by either teacher or student. In c) applicability, the usefulness of the product was also discussed. The table can be a regular classroom table usable by either student or teacher. The product must also be a perfect demonstration table for the three core competencies in EIM, and also the leg stand frame is designed to accommodate the table tops with different core competency. Moreover, in d) portability, the researcher chooses a material which is lesser in weight in order to reduce the total maximum weight and fit to the desired size of the unit. The Electrical multi-purpose table weighed a maximum of 27 kgs. Easy assembling and disassembling of the leg stand and the table top was also considered during the assembly. There is also an adjuster on each edge of the two front table legs, where the table can flat fit to the ground. Additionally, the weight of the product is manageable for transporting in any part of the room or transported to other rooms. Next feature is e) safety, in this study, it pertains to the overall compliance of the product or device to prevent inadvertent or hazardous operation. The electrical multi-purpose table is equipped with safety devices, such as circuit breaker and light indicators. The electrical circuitry all adheres to the provisions of the Philippine Electrical Code and all materials used are of approved type and compliant with the provisions of the Philippine Electrical Code and other standards. Finally, f) efficiency which is in a more general sense, it is the ability to do things well, successfully, and without waste. The researcher give emphasis to the security of tools, materials and equipment. Materials used is economical but of good quality and available in the local market and can save more electrical consumable materials due to its reduced size and design.
3. The acceptability level of the developed Electrical Multipurpose Table was evaluated by teachers and students in six identified areas: functionality, usability, applicability, portability, efficiency, and safety. This section presents the differences in the perceptions of both respondents. The analysis was done using the Wilcoxon Rank Sum Test.
4. There is no significant difference in the perceptions of the respondents on the level of acceptability of the developed Electrical multi-purpose table. As reflected in Table 13, all the computed values in the four areas are less than the critical value of -1.96 at a 0.05 level of significance. Therefore, the null hypothesis is not rejected. It indicates that both teachers and students have the same perceptions of the level of acceptability in the identified areas.
Based from the findings of the study, the following conclusion can be hereby given:1. The processes in developing the electrical multi-purpose table are outlined from the ADDIE model which includes analysis, design, development, and evaluation. There are four stages in the development of the product a) table top assembly, b) leg stand frame assembly, c) painting works, and d) Electrical installation. 2.
