If people listening receive information in a logical and well-put-together manor they are likely to remain interested and take away with them more of the information. Lectures can also use presentation software to convey information easily. A major disadvantage of a poorly organized lecture means leaving an audience with scattered information; they may want to ask a lot of questions to clear up any misconceptions or for clarification. They also might end up more confused about the topic than before the lecture began.
Lecturers can conduct an assessment of their attempted teaching techniques through a survey or short exam where students can recant what they learned; those giving the lecture can quickly assess their teaching, speaking and organization abilities. However, because of the size of the audience and the length of time it takes to deliver a lecture, the lecture presentation may not lend itself to feedback, which can be a disadvantage of of this format. In addition, lectures allow only passive learning on the part of the audience and don't allow them to take an active role in the discussion.

However, a disadvantage of lectures is that complicated subjects bogged down in theories and concepts can become difficult to explain. Everyone might in the audience may not possess the same learning potential or understand the material in the same manner; lecturers also provide their interpretation of the subject matter rather than one with multiple viewpoints or opinions.
