The document describes the results of assessments given throughout a teaching unit on verb tenses and grammar. After teaching some initial lessons, the teacher noticed aspects that needed changing, such as motivating students and managing time. Modifications were made to engage students through exciting activities instead of textbooks. Diagnostic testing at the start showed only 13% passed, so more lessons on tenses/grammar were added. A formative letter writing assignment saw 80% succeed as they had practiced the format. Summative end testing showed 70% achieved the learning goals, with improvements from the initial diagnostic results.
