Investigation study of integrated vocational guidance on work readiness of mechanical engineering vocational school students

21st Century Learning shifts the learning paradigm to change the way of learning and teaching. Organizing education containing three aspects of work readiness (knowledge, attitudes, and skills) is challenging for educators. Many educators only use the explanation method in vocational guidance, and do not fully use the demonstration method of learning machining practices related to how to work, how to behave in the workplace, and how to comply with regulations in the workplace, this causes many graduates who only have minimal competence, so they are not according to industry standards. This study aims to determine the effect of integrated vocational guidance on student work readiness in Vocational High Schools. This research is quasiexperimental research with a quantitative approach. The experimental design used was a pretest-posttest non-equivalent control group design. This study used a control group with an explanation method and an experimental group with a demonstration method. In the explanation method in this study, the teacher explains how the machine works verbally, while in the demonstration method, the teacher demonstrates how the machine works and operates it, followed by student activities practising it again in the machine laboratory. The population of this study were students of the Mechanical Engineering Expertise Program. Data collection is done by observation and tests. Observations were used to collect data on technical skills and work attitudes. The test is used to collect data on aspects of basic knowledge. The results showed that: (1) The value of work readiness (knowledge, attitudes, skills) using the explanation method based on the Minimum Completeness Criteria (MCC); (2) The value of work readiness (knowledge, attitudes, skills) with the demonstration method above the MCC. This research has practical implications for vocational teachers who provide vocational guidance services with demonstration methods to students, especially the latest technological advances for learning, such as the use of the internet, digital technology, VR/AR, etc.
