DESIGNING ENGLISH GRAMMAR EXERCISES VIA THE WEBSITE EDUCANDY TO IMPROVE GRAMMAR COMPETENCE FOR HIGH SCHOOL STUDENTS

Mastering grammar is a vital aspect of studying English, yet many students struggle to understand and memorize grammatical structures, as well as apply grammar to their homework. This study intends to examine the efficiency of the exercises on the Educandy website to help 11th graders at a high school in Vietnam enhance their grammar competency. The grammar contents that students learned during the experiment were the knowledge from the English textbook used in their school. An experimental group of 15 students took part in a 7-week experiment, in which they were required to apply the exercises via Educandy website. Research tools included a grammar test given before and after the intervention, along with two questionnaires for the student groups involved. The results showed a significant improvement in students' post-test scores and a strong connection between practicing online exercises and better grammar performance. Additionally, students gave positive feedback on using the Educandy website, suggesting that it could be an effective tool for improving grammar learning.
