Gema Cow-Pu: Development of Mathematical Crossword Puzzle Learning Media on Students' Critical Thinking Ability

oai:ojs.pkp.sfu.ca:article/1Critical personality is a skill that must be possessed in order to survive in the global competition of 21st century society. Given that critical thinking education is an important part of human life, innovations must be carried out to foster students' critical thinking. One of the studies he conducted was the innovation of crossword learning media (GEMA COW-PU). In this study, the development of learning media for mathematical crossword puzzles (Gema Cow-Pu) was carried out on Geometry material at YALC Pasuruan Middle School and tested the learning media on students' critical thinking skills. This is intended to determine its validity and practicality. The specialty of this research is research and development based on the Borg n Gall development model. The research subjects were ten students of class VIII. The instruments used were validation sheets, teacher and student response questionnaires, and student learning outcomes tests. The results showed that the relevance score of Gema Cow-Pu learning media with students' critical thinking skills was in the very valid category with an average score of 89.75 percent, and Practical with a percentage of 95.3%. This shows that the Gema Cow-Pu learning media meets valid and practical criteria so that it can help students' critical thinking skills in learnin

Professional development in an institution through the GROW model

The teacher is a facilitator in helping the main character, namely students, achieve learning goals in class. In their professionalism as educators, teachers are expected to have abilities in material and teaching skills in conveying material so that students can understand it. The main aim of this research is to focus on the GROW model suitable for professional development in teaching styles. The GROW model consists of collaboration with Goals, Reality, Obstacles/Choices, and Will/Way Forward. This study will also focus on the demand for GROW coaching and the challenges of implementing the model in educational institutions. This is a research study based on literature and personal experience. Even though the GROW model is a new professional development process, it will be a more effective way of professional development if it is applied appropriately and constructively. Several issues and action plans must be adequately considered to implement this model. The researchers explain and introduce the GROW model and its impact on professional development with the help of literature and from the perspective of their practical experience
