Effectiveness of memorization in the classroom increases in comparison to individual memorization, because it depends on situational context. To memorize something while being approved by an instructor helps the retention of the information due to its connection to a positive psychological experience. Social encouragement and approval are crucial for strengthening the effectiveness of memorization.
Although each person has his own techniques of memorization that depend on his learning style and personal abilities, memorization in the classroom gives an opportunity to acquire new techniques, and this enriches one's approach to memorization. Among the most common techniques are rote memorization (repetition) and different mnemonic strategies.
It is a known fact that we get the majority of our information through the visual channel, while other channels of perception are underdeveloped and not used intensively. Memorization in the classroom contributes to the development of perception through listening, and thus strengthens auditory learning style. If you teach a chemistry course, for example, in which students are expected to manipulate different objects during experiments, the kinesthetic mechanism can be switched on as well. Hence, memorization in the classroom contributes to the diversity of learning styles.
Memorization in the classroom has its positive effect in sharing and retention not only information, but also values. We prescribe to the data to be memorized not only informative, but social meanings as well. So, it creates a basis for a common value approach to the social reality.
The fact that an instructor or lecturer can check and control the correctness of the information memorized is a strong point of memorization in the classroom. If you teach a foreign language, for example, your students might memorize incorrect pronunciation or sentence structure. It will be difficult to eliminate such errors if they become habitual.
