3. Clarity and Conciseness in Educational Communication
Clarity of expression is the foundation of an effective instructional message. Teachers often unintentionally include too much information in an attempt to be thorough, yet overwhelming students with content can reduce the effectiveness of learning. Information overload occurs when the amount of presented material exceeds the learner’s cognitive processing capacity, which may lead to reduced understanding and decreased engagement (Sweller, 1994). Conciseness does not mean oversimplifying the message, but refining it—removing everything that does not directly contribute to learning.
Good practice includes using:
-
short sentences,
-
direct instructions,
-
emphasis on key concepts.
According to Mayer’s cognitive theory of multimedia learning, reducing the amount of text and focusing on essential information improves comprehension (Mayer, 2009).
