Development process of the intervention
The NL online intervention programme was developed collaboratively by a diverse team, including health and nutrition education professors, middle school health education teachers, school dietitians, film crews from the university’s film and television department and network engineers from professional manufacturers. The programme’s framework and content were meticulously crafted, incorporating specific learning goals, scenario scripts and learning materials for each unit. These components were designed to align with the corresponding NL indicators, ensuring its effectiveness.To ensure the programme’s relevance and applicability, a formative evaluation study was conducted. Feedback from a focus group of ten college students was obtained using McGuire’s information processing modelTo facilitate the learning process and provide easy access to materials, an online learning platform was developed and tested using Experience Application Programming Interface. This versatile e-learning specification allows for the collection of data in the form of activity statements, tracking participants’ progress and performance throughout various training and learning activities. The platform operates on both smartphones and computers, ensuring convenience for the learners.
