Answer to Question 1

A null hypothesis might be retained because it is, in fact, true. The treatment may not have made any difference, or there may not be a relationship between variables. Although it's false, the null hypothesis may be retained because of internal validity problems in the design or lack of power in the design.

Answer to Question 2

The term prior knowledge in constructivist theory refers to the process of previous knowledge, interests, attitudes, goals, and so on that learners bring to a learning task influencing the information to which one attends and the interpretation one gives the task.
