Developing The Radius Turner as The Radius Turning Tool

摘要

The study was conducted in order to determine: (1) the feasibility of radius turner as a radius turning assistance tool; and (2) the achievement of radius turning competency displayed by the students after they had operated the radius turner. The design that the researchers applied in conducting the study was the Research and Development (R&D) with the ADDIE Model. The data for the study were gathered from the second semester students who attended the B1, B2 and D1 Lathe Machinery Class. Within the data collection, the researchers applied the observation, the questionnaires and the documentation. Then, for the data analysis the researchers implemented the descriptive quantitative technique. The results of the study have been as follows: (1) the radius turner that have been developed successfully is fit for its use as the radius turning tool in the radius profile of the lathe; and (2) the students' radius turning competency achievement after they have operated the radius turner have been 81.00% in achieving the maximum score.
