Concept:Laboratory method is a hands-on, experiential approach where students learn by doing experiments, using instruments, and directly interacting with materials. The principles that guide this method include moving from indefinite to definite, known to unknown, and learning by doing. The principle of moving from concrete to abstract belongs to general psychology, not specifically to the laboratory method.
Explanation:Step 1: Identify the principles commonly associated with the laboratory method. These are:
- From indefinite to definite: learners get direct, concrete experience to make vague ideas clear.
- From known to unknown: teaching starts from learners' prior knowledge and progresses to new content.
- Learning by doing: students actively participate in experiments and activities.
Step 2: Examine the principle "From concrete to abstract". This is a psychological principle used in general teaching methods where learners first grasp tangible examples and then move to abstract concepts. However, in the laboratory method, the entire process itself is already concrete through hands-on work; the method does not specifically follow a sequence from concrete to abstract. Instead, it inherently uses concrete experiences for direct learning.
Step 3: Therefore, among the given options, "From concrete to abstract" is not a principle exclusively tied to the laboratory method, making it the correct answer.
Answer:Option A – From concrete to abstract is not related to the laboratory method.
