1. Content of the lecture
The lecture is on some nice theory with some nice application – you talk about both.
The application has strong connection to something well-known for the students.
The lecture is 90% clear for any good student of the class (10% remains a mystery) – at least half of the lecture is clear for everyone who listens, regardless of how good they are.
You are not too fast and adapt the tempo to the class – students are allowed to ask questions during the lecture.
You use different formats (theory explanation, example calculation, experiment, short video etc. – always more pictures than formulas).
You ask short questions and give short tasks (short problems to think over for 5-10 minutes, but no long calculations) during the lecture.

How to create material for lectures ?
Educational materials produced by professionals is essential. Therefore, is it very useful to establish the right connections.
For example, booklets created by the environmental education department at Bogor university (IPB) in Indonesia is adapted to local curricula. Thanks to SciEd network, such books were donated to our local partner (MAPALA Singinjai Jambi) and can then be used for inspiring SciEd lecturers.
Another source of inspiration comes from our own research and scientific material.
For example, figures from a scientific publication (here, Foster et al (2011) showing lateral sections through primary forest and oil palm plantation in Sabah) can be used as pattern for colorful drawings.
Example of material for lectures created by SciEd can be downloaded:
We made a video about SciEd for the conference NetSci 2018 for NetSciEd satellite
