As is often the case, there is usually more than one way to approach a problem or task.
Currently, my students use what they were taught in the lessons (which is expected). When they stumble upon a problem (e.g. a project that has parts that they are unsure how to approach) they very often get stuck. This is because they haven't been taught some specific thing that is related.
I want the students to be more independent in their learning, and to look for that other approach on their own. How can I structure a lesson that would foster independence and give the students the ability to look for a new approach when needed?
The students' level is somewhat advanced high school level.
