One of the strategies to improve teachers' skills and professionalism is the practice of continuous professional development. To fulfill the demands of students and learning in the 21st century, teachers must have a strong foundation and knowledge of ongoing professional development. However, a-business-as-usual continuous professional development does not contribute to any significant improvements for teachers of junior high school in Pematangsiantar. The objective of this research was to develop a management model for teachers’ continuous development. This is carried out through competency-based training with a heutagogy approach. A development model called ADDIE, which stands for Analysis, Design, Develop, Implementation, and Evaluation was used to develop the management model. The subject of this research was 80 junior high school students in Pematangsiantar. They were divided into 30 and 50 people for the limited trial and the broad trial, respectively. Questionnaires were distributed as the instrument of data collection. The data was then analyzed using a statistical descriptive analysis technique. The research found that the effectiveness of the competency-based training management model was measured by the N-Gain score, in which the G-value was 0.79 and 0.82 for limited trial and broad trial, respectively, which was in the high category. The results of the assessment of the effectiveness of the model obtained an average value of 94%, which was in the "very good" category. The effectiveness of the training program was assessed from the aspects of reactions, learning, behavior, and results, and the results show that the assessment of the classroom action research training program obtained an average score of 92%, or a very good category, which means that the classroom action research training program is very effective in improving teachers’ competence. The significance of this model has been proven to give an innovative solution to teachers’ continuous professional development. Doi: 10.28991/ESJ-2023-07-01-014 Full Text: PDF

Published: November 2022

This study is designed to support the development of strategies to recover from the disrupted impact of COVID-19 on HE institutes of the South Asian Region (SAR), as the nations in this region are severely cursed by poverty and unemployment. During the unusual phase of the COVID-19 pandemic, the face-to-face learning method is no longer appropriate, and the crisis leads to force on distance learning instead of physical learning. Like all other educational institutions, HE institutions are also in big trouble. Changes in educational structure change the pattern of academic work, which may have an inverse impact on acquiring knowledge and improving skills. Not only students but also a greater number of teachers at the HE institutions required to continue their service through online during this closure period. However, well digital infrastructure and digital contents appear to be the prime requirements for this educational transmission, which are extensively accessible in SAR countries. By following a mixed-methods strategy, the study specifically examines the impact of the pandemic on higher education in the South Asian Region, with an emphasis on the impact on learners, educators, and institutions, and to identify the measures that have been taken by these countries to survive and continue the education system with all the obstacles of the crisis. It concludes with some vital suggestions that may be applied to mitigate the crisis moment and assist in moving forward with more technological advancements for a new future.

Por lo tanto, la adquisición de una lengua diferente a la materna es importante para sostener relaciones interpersonales y profesionales con los demás (Uribe, et. al. 2008). De acuerdo con Rojas et. al. (2019) es importante para la formación profesional el lograr un desarrollo de una competencia comunicativa en inglés, y de aquí la necesidad de centrar la atención en el proceso de enseñanza aprendizaje del inglés y el desarrollo de las habilidades comunicativas. El desarrollo la comunicación oral en inglés requiere de la implementación de metodologías específicas que tomen en cuenta diferentes factores y se adapten a las necesidades de cada uno de los estudiantes en el aula. El objetivo principal de este trabajo es presentar una breve revisión de literatura que propone la implementación de la pedagogía del translenguaje con el objetivo de desarrollar la capacidad de competencia comunicativa oral en inglés. En general, los resultados de esta revisión de literatura muestran las principales características del translenguaje, sus beneficios, y algunas estrategias y actividades que pueden ser implementadas en clases bilingües. Una futura investigación sobre este tema desarrollará un proyecto de investigación-acción en donde se implemente la pedagogía del transleguaje en una escuela primaria bilingüe.
