The Distributions of Vocational High School Teachers’ Advanced Digital Competence (ADC)

Digital competence is one of the significant skills to be possessed by the teachers as the impact of rapid technology development in many aspects such as economy, education, health, and environment. Various digital competence measurements and frameworks had been developed to ensure that someone has an advance digital skill and one of those is DigComp 2.1 by European Commission. Many previous studies had been studied about teachers’ digital competence levels influenced by some factors such as age, gender, working period, and educational background. However, it is infrequently analysed that the advance digital competence (ADC) of Vocational High School (VHS) teachers is differentiated by engineering field and non-engineering field, area or region and its school quality. Moreover, this study aimed: (a) to show the ADC level analysis between VHS teachers in engineering and non-engineering school, (b) to delineate the ADC level of VHS teachers based on the islands where the school is located, and (c) to represent the impact of school quality towards the VHS teachers’ ADC level. The data was analysed using a quantitative approach with a descriptive statistics method. Additionally, the instruments of the survey to collect the data were adapted from the DigCompEdu framework in part of advanced level and measured using Likert scale. The participants of this study were 392 respondents but, it was classified and divided into some fields based on VHS fields, islands and school accreditation. The result of this study expounded that VHS teachers in the engineering field have higher scores at the ADC level even though there are some ADC components that should be upgraded by the VHS teachers in both fields. Meanwhile, islands and school accreditation had no significant impact yet showed the opposite result

These four variables explain 51.3 percent of the variance of Behavioral Intention to Use

A Contextual Semi-Assisted Project-Based Learning on Ocean Wave Energy: Pre-service Physics Teachers’ Perceptions

The lack of technological innovation in the utilization of ocean wave energy as a renewable energy source is caused by a lack of public knowledge about this matter. Therefore, it needs to be introduced early, especially to pre-service teachers through innovative and fun learning. The aim of this study was to identify the responses of pre-service physics teachers about the learning program to introduce the concept of utilizing ocean wave energy. The research subjects were 31 sixth semester students who are taking environmental physics lectures in the physics education study program at one of the teachers' university in West Nusa Tenggara Province for the 2019/2020 academic year. The sample was taken by using purposive sampling technique. Data collection was carried out by means of observation, interview, and questionnaire techniques. All data collected were then analyzed simultaneously descriptively. The findings of this study showed that almost 90% pre-service physics teacher students agreed that the learning program had a positive impact on increasing interest, motivation, critical thinking skills, and creative thinking skills, and made them easier to solve problems and grow solid cooperation. Therefore, it can be concluded that pre-service physics teacher students agree to the use of semi-assisted project-based learning programs with contextual problems

A contextual semi assisted project-based learning (SA-PjBL) about ocean wave energy: Creative thinking of pre-service physics teachers

One of the factors that have become an obstacle in the development of techno-logy to use ocean wave energy as a renewable energy source is the lack of human resources who have expertise in this field. Therefore, in the long term, it is necessary to introduce basic knowledge to the young generation about wave energy and other renew-able energies and even must equip them with important skills such as creative thinking skills. This study aims to introduce students to how to utilize ocean waves as renewable energy while at the same time developing student creative thinking skills through semi-assisted project-based learning. This type of research is weak experiment research with one group pretest-posttest design research. The research was conducted on 31 pre-service physics physics teachers who were taking environmental physics lectures at a teacher training university in West Nusa Tenggara. The performance appraisal data were analyzed descriptively while the test result data were analyzed using the N-gain and the Wilcoxon test. Based on the results of data analysis, it was obtained <g> = 0.725, which means that there was a high increase in students' mastery of the concept of using ocean waves as a renewable energy source. In addition, the results of the performance appraisal data (score > 3) indicated that at each stage of learning, students were provided with indicators of creative thinking skills with very satisfied categories. Therefore, it can be concluded that environmental physics lectures using semi-assisted project-based learning able to improve students' mastery of concepts and creative thinking skills

A Simple, Rapid Analysis, Portable, Low-cost, and Arduino-based Spectrophotometer with White LED as a Light Source for Analyzing Solution Concentration
