BackgroundWe developed the informed health choices (IHC) primary school resources to teach children how to assess the trustworthiness of claims about the effects of treatments. We evaluated these resources in a randomised trial in Uganda. This paper describes the process evaluation that we conducted alongside this trial.ObjectivesTo identify factors affecting the implementation, impact and scaling up of the intervention; and potential adverse and beneficial effects of the intervention.MethodsAll 85 teachers in the 60 schools in the intervention arm of the trial completed a questionnaire after each lesson and at the end of the term. We conducted structured classroom observations at all 60 schools. For interviews and focus groups, we purposively selected six schools. We interviewed district education officers, teachers, head teachers, children and their parents. We used a framework analysis approach to analyse the data.ResultsMost of the participants liked the IHC resources and felt that the content was important. This motivated the teachers and contributed to positive attitudes. Although some teachers started out lacking confidence, many found that the children’s enthusiasm for the lessons made them more confident. Nearly everyone interviewed thought that the children learnt something important and many thought that it improved their decision-making. The main barrier to scaling up use of the IHC resources that participants identified was the need to incorporate the lessons into the national curriculum.ConclusionThe mostly positive findings reflect the trial results, which showed large effects on the children’s and the teachers’ critical appraisal skills. The main limitations of this evaluation are that the investigators were responsible for both developing and evaluating the intervention.

Introduction Adolescents encounter misleading claims about health interventions that can affect their health. Young people need to develop critical thinking skills to enable them to verify health claims and make informed choices. Schools could teach these important life skills, but educators need access to suitable learning resources that are aligned with their curriculum. The overall objective of this context analysis was to explore conditions for teaching critical thinking about health interventions using digital technology to lower secondary school students in Rwanda. Methods We undertook a qualitative descriptive study using four methods: document review, key informant interviews, focus group discussions, and observations. We reviewed 29 documents related to the national curriculum and ICT conditions in secondary schools. We conducted 8 interviews and 5 focus group discussions with students, teachers, and policy makers. We observed ICT conditions and use in five schools. We analysed the data using a framework analysis approach. Results Two major themes found. The first was demand for teaching critical thinking about health. The current curriculum explicitly aims to develop critical thinking competences in students. Critical thinking and health topics are taught across subjects. But understanding and teaching of critical thinking varies among teachers, and critical thinking about health is not being taught. The second theme was the current and expected ICT conditions. Most public schools have computers, projectors, and internet connectivity. However, use of ICT in teaching is limited, due in part to low computer to student ratios. Conclusions There is a need for learning resources to develop critical thinking skills generally and critical thinking about health specifically. Such skills could be taught within the existing curriculum using available ICT technologies. Digital resources for teaching critical thinking about health should be designed so that they can be used flexibly across subjects and easily by teachers and students.
