Why is Jeffreys prior useful?
It is an uninformative prior, which means that it gives you vague information about probabilities. It’s usually used when you don’t have a suitable prior distribution available. However, you could choose to use an uninformative prior if you don’t want it to affect your results too much.
Why is it important to understand students prior knowledge misconceptions?
In the instances when prior knowledge is inaccurate, instructors will need to spend some time helping students to come to terms with their misconceptions before they can go on to help the students build new knowledge. In such a case, the inadequate and inaccurate prior knowledge will tend to hinder learning.
How does prior knowledge affect learning?
When students’ prior knowledge (acquired before a course) is accurate and appropriate, it will aid learning. But when students’ prior knowledge is inappropriate or inaccurate, it will hinder learning. But in some cases, students can apply a procedure without understanding what they are doing.
Why is it important to know your prior knowledge?

Which is the lowest level of prior knowledge?
In the prior knowledge model applied in the present study, a distinction was made between declarative and procedural knowledge. At the lowest level, prior knowledge may consist of declarative knowledge, which is the knowledge of facts and meanings that a student is able to remember or reproduce.
How to engage prior knowledge in a class?
Begin a course or unit with a “benchmark lesson” whereby you present a provocative question that doesn’t have one clear answer. Ask for suggestions about possible answers (get as full a range as possible). Solicit explanations to get at the range of student thinking (increase participation by having them discuss in pairs first if you’d like).
