V3SK model

The tripartite V3SK model, integrating values, skills, and knowledge, has been explored in various educational contexts but remains underutilized in English language teaching. This study aimed to investigate the effect of the V3SK model on Iranian high school students’ grammar achievement using an explanatory mixed-methods design. Participants included 43 high school teachers and 452 pre-intermediate level students, selected based on standardized placement tests. Teachers were randomly divided into groups of experimental (N = 22) and control (N = 21). The experimental group participated in 15 training sessions focused on the V3SK model dimensions. Subsequently, students from both groups completed a researcher-designed grammar pretest and received 20 sessions of instruction over three months, followed by a posttest. Quantitative data were analyzed using Mann-Whitney U tests, revealing significantly higher grammar achievement in the experimental group. Qualitative thematic analysis of interviews with 15 experimental group teachers identified 11 themes that explain the model's contributions, including enhanced motivation, innovative teaching, and differentiated instruction. These findings underscore the V3SK model's potential for improving grammar instruction in English as a Foreign Language (EFL) settings, offering valuable insights for teacher education and curriculum development.
