| Introduction|| |
The word Lecture is derived from the Latin word 'lectus' which can be interpreted as 'to read' and the act of reading dated back to the 15th century. Merriam–Webster online dictionary defined lecture as a discourse given before an audience or class especially for instruction. Gazi and Laskar  also defined lecture as a carefully prepared oral presentation of facts, organised thoughts and ideas delivered by a qualified person to students or participants. Lectures are essential parts of undergraduate medical education and remain an important tool for the transfer of information to students. They are given to provide a framework of knowledge to students who are then expected to search for extra information on the subject being taught.
Despite its major role in the undergraduate medical education, lectures are known to have several limitations including a passive mode of learning, lack of effective feedback from students and are sometimes boring. The traditional method of lecture delivery where the lecturer simply reads out already prepared notes on the subject is still practiced today; however, some lecturers still prefer the use of multimedia software presentation like Microsoft PowerPoint. Onotai et al. in a study done among the medical students in Port Harcourt, Nigeria found that lecture delivery with the use of multimedia Microsoft PowerPoint was the preferred mode of lecture delivery. Their finding is similar to studies done elsewhere., Multimedia Microsoft PowerPoint is credited to have the ability to integrate text, pictures and images thus improving the educational value of the subject and, therefore, creating an active learning process., Several disadvantages of PowerPoint presentations have also been identified such as high speed and neglect of interaction between lecturer and students.
In the clinical departments of Bayero University Medical School, the duration of lectures varies between 1 and 2 h.
This study intends to find out the preference and views on lecture delivery methods among the clinical students of Bayero University Medical School. The outcome of this study will not only aid learning but assist the lecturers in achieving their set out learning objectives.
To our knowledge, no study has been done on the preference and views of lecture delivery methods among the clinical students of the Bayero University Medical School, Kano, Nigeria.
| Materials and Methods|| |
This is a cross-sectional observational study involving the 400, 500 and 600 levels clinical students of the Faculty of Medicine, Bayero University Kano. Ethical approval was sought from the appropriate authority of the university. The questionnaire was pretested before being administered to the students. The self-administered questionnaires were shared after a careful explanation of the research and consent obtained. The questionnaire administered was divided into the four subsections. The first subsection involves basic biodata and the subsequent subsections contain questions on preference and views on the available lecture delivery methods.
All data derived from the questionnaire were entered into using Microsoft excel 2007 and analysed by the use of frequencies and percentages. The difference between the various classes was analysed by Statististical Pakcage for Social Sciences (SPSS) version 16.0 (SPSS, Inc., Chigaco, 111) using one-way ANOVA and a P < 0.05 considered to be significant.

| Discussion|| |
The predominant method of lecture delivery by teachers in the Bayero University Medical School is the multimedia powerpoint (82.4%) [Figure 1]. This is in contrast to the Port Harcourt Medical School  where the traditional method is still the predominant method of lecture delivery (74.6%).
According to Onotai et al. and Naqvi et al., the selection of lecture delivery method is determined by a variety of factors including availability of necessary facilities, lecture topic, students' population, the environment and especially the lecturers' personal preference.
In this study, the majority of the students (70.9%) prefer a combination of the traditional and power point methods for lecture delivery whereas 12.6% prefer the use of power point only. Our finding is similar to those of Chopra et al. where 70.4% also preferred a combination of both methods. However, our findings were in contrast to those of Hashmi et al. where the majority (79%) of the students prefer the multimedia method and Onotai et al. where 69.5% of the medical students prefer the traditional method, although the questionnaires used in these studies did not give the option of a combination of both traditional method and powerpoint as a lecture delivery method.
The traditional or chalk and talk method and the multimedia powerpoint methods have their individual merits and drawbacks. The learning objectives should determine the best method of lecture delivery. If the objectives are to retain complex graphics, e.g., anatomy, flow charts animation and figures; multimedia powerpoint is the preferred method, whereas if the objectives are to retain information through interactive dialogue and explanation, the traditional method is a superior method.
In this study, the majority (70%) of the students are of the view that the duration of lectures should not exceed 1 h. The ideal lecture duration period has been a topic of several researches.,, Badave and Dhanajay  stated that the majority of the students opined that the ideal lecture period should be between 40 and 50 min. Similarly, Kulkarni et al. in their work stated an ideal lecture duration study of 45 min. Stuart and Rutherford  stated that students' concentration rose steadily to reach a maximum in 10–15 min and fell steadily thereafter. They suggested a maximum duration of 30 min. These studies ,, emphasise the futility of marathon lecture periods in the classroom for the purpose of covering large course content. Generally, most students (70%) at all levels agree that the duration of the lecture should not exceed 1 h, which was significantly different among the classes. The reasons why fewer students in the 400 level of study agree that the lecture period should not exceed 1 h is not clear, but it is worthy to note that in the 1st year of clinical postings, emphasis is placed mainly on bedside and ward round teachings, instead of lectures.
The importance of limiting the period of lectures was emphasised by Clark and Meyer  who stated that the visual and auditory channels are the routes for processing information and too much information entering either or both channels may lead to cognitive overload with the resultant reduction in the assimilation of information.
Most of the students (65.2%) are of the view that the lecturers, who use the multi-media powerpoint method, did not spend enough time to explain the salient issues on the slides, which is a major drawback of the use of this method. In an attempt to cover the scope of lecture topics, there may be a tendency to use many slides to illustrate and explain the course content. On the contrary, 67.8% of the students opined that the traditional methods provide adequate time for questioning. This is a major advantage of this method, which provides optimal interaction, between the teacher and the students.
| Conclusion|| |
A combination of the traditional and multimedia powerpoint methods is the preferred lecture delivery method of Bayero University Kano clinical students and they opined that the lectures should not exceed an hour.
