Abstract Background A diverse cohort of students join our UK postgraduate public health programme. We wanted to reduce attainment gaps between students. Active and inclusive educational activities may be important mechanisms for reducing attainment gaps as well as promoting student wellbeing. Our aim was to explore how active and inclusive curriculum design could support development of public health functions (e.g., designing interventions to address health inequalities) whilst reducing attainment gaps. Objectives Our 12-week module included a project to model determinants of adolescent’s health inequalities and design an evidence-based intervention to address determinants. Informed by Fink’s taxonomy and the assessment for learning framework, we designed educational activities (i.e., small group work and presentations, ethnographic visits, discussions with stakeholders) and assessments (i.e., group poster presentation and individual critical reflection) to structure the project. We assessed attainment gaps in student marks and surveyed student attitudes to the project (1 = strongly disagree; 5 = strongly agree). Results 53 students (9 groups) completed the assessment with the following marks: poster (M = 61, SD = 7), critical reflection (M = 59, SD = 9), overall mark (M = 59, SD = 10). More students received ‘fails’ and ‘distinctions’ when only the critical reflection was considered (p < 0.001). Students (N = 39; 72% response rate) agreed that activities were intellectually stimulating (M = 5, SD = 0.8), supported their learning (M = 4, SD = 0.8) and made them feel included (M = 5, SD = 0.7). Active learning approach (i.e., benefits of interactions; creating effective groups); student’s caring and commitment; choice and inclusivity; complex and authentic tasks; informal, formal and timely feedback were highlighted. Conclusions Evidence that an active and inclusive approach functions to reduce attainment gaps is equivocal but appears to promote engagement, inclusion and learning. Key messages • Active learning strategies combined with authentic and flexible tasks and rich in feedback stimulate student’s interactions, inclusivity, and learning with potential for reducing attainment gaps. • Active and authentic education requires educators to work on how to properly implement these strategies.
