Ed-Venturers in Action is a four-theme instructional model for a Grade 4 EFL class in Thailand (N≈40) integrating CLIL and PBL, with CALL as supportive practice. It was developed to address a common pedagogical need in primary EFL: grammar lessons can feel repetitive, class time is limited, and learners often fail to transfer target forms into meaningful writing and speaking. Over eight 50-minute periods, each theme follows a two-period cycle. Period 1 uses a short CLIL text (city, country, continent, global issues) to introduce one grammar target, followed by brief digital game micro-practice (Wordwall, Quiz.zep.us, Baamboozle) to sustain attention; similar games may be assigned for home review. Period 2 guides students with sentence frames to write a 70–90 word theme summary, draft a short presentation script, and rehearse speaking. The sequence culminates in a three-panel Environmental Trifold Poster (Lampang–Thailand–World) and a group presentation. Using a one-group pre–post design, data include a 30-item grammar test administered via Google Forms on iPads, writing and speaking rubric scores, a brief SEL/GCED survey, engagement checklists, and game logs (accuracy, attempts, time). The session shares classroom evidence and ready-to-use materials for teachers seeking a practical, low-prep model.
