There are disadvantages to using the lecture method:

•       if the material of lecture is not interesting, it makes the listener bored.

D.    COMPONENTS OF LECTURE

An effective lecture  consists of three components, an Introduction, Body and Conclusion,designed to promote and support learning. In the following sections, you will see how to develop these components to produce an effective lecture.

1.       The Introduction

       The introduction is the first thing. The duration is about  three to five minutes of the lecture. The introduction should do the following:

·         Establish friendly communication to provide a positive learning environment in which audiences feel comfortable.

·         Gain attention and foster motivation. We might present a meaningful problem to audiences and describe the lecture as a solution of the problem.

·         Clarify the purpose of the lecture and describe how it is organized.

·         Announce the lecture topic as a title.

·         Make a statement about the topic and how it will be developed.

2.         The Body of the Lecture

In addition, a lecture should be organized based on the relationship of the ideas presented. Examples of relationships that can be used to organize lecture information include the following:

·         Component (part to whole)–shows how a larger idea is composed of several smaller ones. "Before we can begin to talk about how urban planners tackle traffic congestion, we need to look at how psychology, economics and tradition contribute to the present-day layout of cities."

·         Sequential–deals with chronological or cause/effect relationships. "Although the causes are quite complex, let’s look at how mass unionization in the 1930s contributed to prosperity in the 1950s."

·         Material to purpose–information or a procedure is presented followed by its purpose or use (the "what" followed by the "why"). "Now that we know what Marxism is, let’s look at how Marxist theory can be used to address inequality between men and women."

·         Comparison–comparing two or more things using an explicit basis for comparison. "The recent reintroduction of the gray wolf into Yellowstone National Park once again demonstrates the inherent conflict between environmentalists and business, in this case ranchers. In the next twenty minutes, let us compare the Yellowstone controversy to efforts twenty years ago to clean up Love Canal and see if we can use this comparison to look for ways in which environmental and business interests can learn to work together.

·         Use transition words as you present. Using transitions or links ("therefore," "because," "as a result") show how pieces of lecture information relate to each other. Verbal or oral cues also alert listeners to more significant information.

 o   It is especially important to remember. . .

 o   Please note the following . . .

 o   You will need to memorize. . .

 o   I will ask you to recognize . . .

 o   You should be able to apply . . .

3.         Capture Attention

 By employing techniques such as the following:

   ·         Change the mode of presentation (for example, oral to visual).

   ·         Employ concept-related humor.

   ·         Demonstrate enthusiasm about your subject.

   ·         Encourage note taking by speaking slowly and repeating important information.

4.        The Conclusion

  

       It should be used to reinforce peoples’ learning of the information as well as to clarify any misconceptions regarding their understanding of the concepts presented. Try to do the following in your lecture conclusion:

 ·       Repeat and emphasize, it is a main points. Signal people that you are going to summarize and reemphasize main points. Or, even better, have several students summarize your main points. This procedure will help you to get feedback as to whether or not people identified the important information. It is also helpful to rephrase information in order to clarify key ideas.

 ·       Encourage questions from people. To allow people’s time to review their notes, pause for a few moments after asking for questions. Remember, however, that it is often difficult for people to respond to the vague "Any questions?" Instead, ask specific, leading questions. By doing so, you will encourage your students to review their notes and formulate questions of their own. In this way, any misconceptions can be clarified, and understanding can be reinforced.

 ·      Relate content to previous and subsequent topics. The last few statements in the conclusion should provide a connection between this lecture and previous lectures (as well as those to follow).

E.     ASPECTS OF LECTURE

  There are basically two aspects to nonverbal behavior,  body language and voice.

   ·         Speaker-audience distance.

   ·         Body movement and stance. Body movement and posture can convey messages to your audience.

    ·         Facial expressions. Facial expressions tell people how you feel about them and yourself and it can help them to get  the    content of the message. Regular eye contact helps you establish credibility. Look directly at different individuals as though you were carrying on a conversation with them.

   ·         Gestures. Purposeful movements of the head, arms, hands and shoulders accentuate or dramatize ideas. Three characteristics of effective gestures include relaxation, vigor, and timing. Use your body to indicate a change of topic or transition.

   ·         Voice variables allow the speaker to make a message clear and interesting. Some of the vocal characteristics of good speaking are as follows.

     o    Strength. Speak loudly enough so that the audiences can listen clearly.

          o    Pronunciation.
