The laws of learning make learning more interesting to study.
Explanation:
The learning laws were first proposed by Edward Thorndike, a famous psychologist. According to him, there are three rules of learning, they are- readiness of learning, exercise of learning and effect of it.
To make learning lasting and interesting one should always follow these rules. Readiness states- that learning can be adopted only if the learner is ready to, this can be done by arising their interest on the topic by some pre-activity and making them understand that learning is essential; Exercise states: that the more you revise the more you memorise, it involves consistent practice; law of Effect says: learning can be strong and interesting if its associated with satisfying feeling and is weak when associated with unsatisfying feeling.
If their data they collected from their experiment proved their hypothesis correct, then yes, their supported hypothesis can be called a scientific theory.
