The impact of online mentoring in implementing radec learning to the elementary school teachers’ competence in training students’ critical thinking skills: A case study during covid-19 pandemic

This study aims to describe the impact of online mentoring activities in implementing the RADEC (Read, Answer, Discuss, Explain, and Create) learning model on the competence of elementary school teachers in training students’ critical thinking skills. The method was a pre-experiment with a one-group pretest-posttest design involving 25 elementary school teachers in Indonesia. The teachers received online mentoring in implementing RADEC learning model. The research instrument was a questionnaire to measure teachers’ knowledge and skills in training critical thinking. The data processing technique was carried out by calculating the mean and the percentage of each item to obtain a description of the teachers’ knowledge and skills in training students’ critical thinking before and after treatment. The data were analyzed inferentially with a paired sample t-test using SPSS version 22 software to see the impact of the treatment on teachers’ competence in training critical thinking. Based on the results of the paired-sample t-test, for both the knowledge and skills aspects, the probability value (sig) was 0.00 <0.05. This result means that there was a significant difference in the knowledge and skills of teachers in training students’ critical thinking skills before and after mentoring activities. The study results indicate that the online mentoring in implementing the RADEC learning model improved teachers’ competence in training elementary school students’ critical thinking skills. © 2021 Science Education Study Program FMIPA UNNES Semarang.

Design of mobile learning rhythmic gymnastics materials for high school/vocational high school levels as a distance learning media during the covid-19 pandemic

This study used a survey method, collecting data used observation, questionnaires, and interviews. The data analysis technique used in this study is qualitative descriptive statistics. The results of observations of questionnaires and interviews are that;1) There is a need for innovations in designing or developing a media/learning model based on mobile learning that is adapted to the times and technological advances, especially in the subject of rhythmic gymnastics at the high school/vocational high school level so that students can learn independently safely and healthily during the Copid-19 pandemic. 2) Design of mobile learning material for high school/vocational gymnastics is feasible to be used as a media for distance learning during the Covid-19 pandemic, based on the results of expert validation and field trials, namely;1) the results of the validation of the gymnastics material expert explained that the series of rhythmic gymnastics movements were feasible because they could be applied, 2) the results of the validation by the media expert obtained a value of 80% in the very good category, and 3) the results of the validation of the learning experts were 81% in the very good category. While the results of field trials in both small-scale and large-scale trials, the overall results show that the mobile learning design is attractive, easy to use and students can practice the gymnastics movements that have been developed. This shows that the mobile learning design is suitable for use as a distance learning medium in the high school/vocational high school level rhythmic gymnastics material during the Covid-19 pandemic because the media is easy to use and useful in the learning process so that learning objectives can be achieved properly. © 2021 by authors, all rights reserved.
