In total, 166 people comprising of 7 lecturers and 159 students (34% first year students, 34% second year students 34% third year students and 4% lecturers) were given questionnaires that consist of four sections which incorporate the student understanding level after lecture being delivered, different type of teaching methods that may affect the understanding level of students, lecturer’s preparation for lecture delivery and association of the effectiveness of lecture and student academic performance during first year for first semester. Most of the students (52.41 %) have a good level of understanding after lecture delivery. Most of the students and lecturers (mean value of 3.69), think that case study and problem base learning (PBL) are the effective method of teaching. There is a weak correlation coefficient of population between students’ understanding level and lecturers’ self-preparation. There is no correlation between the effectiveness of lecture and students’ academic performance during first year for first semester. In conclusion, there is no correlation between students’ understanding level and lecturers’ self-preparation.

Ruyle (1995) describes the lecture simply as an oral presentation of instructional material. Thus, to see the effectiveness of the lecture delivery by the lecturers, few studies had been carried out where they will be looking into different sources of rating (Berk 2005). The three main parts of a lecture are the introduction, body and summary. Hence, the study of the effectiveness of the lecturers in delivering the lecture can be done to look into all these criteria (Sullivan 1996). The sample subjects selected are students and self (lecturer). Students are chosen because they are the subjects who attend the lectures, thus they can directly evaluate the effectiveness of the lecture while lecturers are chosen to evaluate themselves so that their self evaluation is coherent with evaluation by others. Some of the research issues that have initiated this study are that most of the studies on lecture delivery effectiveness are only based on student ratings (eg: SPPK). Using only one source of information is inadequate and can create bias and unreliability. Therefore our study is to look into other sources to complement the unreliability. The objectives of this study were to determine students’ understanding level, determine the effectiveness of various teaching methods, to associate the lecturers self-preparation with lecture delivery effectiveness, to determine the association between the effectiveness of lectures and students’ academic performance among students first, second and third year Biomedical Science undergraduates 2010/2011 and also first year lecturers of FSKB, UKM, KKL. For the future study, the results obtained from this study can be compared with that of the other lecturers in other universities locally or maybe with international lecturers as well so as to increase our university’s competency level in order for our university to achieve the ranking of one the top universities in Malaysia, or perhaps worldwide. MATERIALS AND METHODS A cross- sectional study was conducted among first, second, third year students and also first year lecturers of biomedical science in Universiti Kebangsaan Malaysia. A name list of the student was taken and the respondents were selected using stratified simple random sampling method while the lecturers were selected using universal sampling. A total of 31` male and 135 female of respondents were selected and from the 166 respondent, there are 112 Malays, 40 Chinese, 10 Indians and 4 Others students involved in this study. Characteristics Gender Races Respondents Number Percent (%) Male 31 18.7 Female 135 81.3 Malay 112 67.5 Chinese 40 24.1 Indian 10 6.0 Others 4 2.4 1st 53 32.0 2nd 53 32.0 3rd 53 32.0 Lecturers 7 4.0 166 100.0 Total TABLE 1: Socio-demographic characteristics of the respondents (n = 166) A structural questionnaire was used consists of respondent’s demographic information. The demographic information requested included name, gender, races and year of study. Part A was created based on first objective, students’ understanding level after lecture delivered. Meanwhile, part B was regarding on second objective which is to determine the effectiveness of various teaching methods and part C based on third objective, to determine the association between lecturers self-preparation with students’ understanding. The answers for part A, B and C are using rating scale from 1(strongly disagree) to 5(strongly agree). For forth objective, the association between effectiveness of lecture and students’ academic performance during 1st year 1st semester is being determined by GPA 1st year 1st Sem. For part B, the various teaching methods that been evaluated included lecture notes alone, assignment, case study, individual/ group presentation, e-SPIN, tutorial and problem base learning. While for part C, the questions asked were to identify lecturers’ preparation that may influence the quality of lectures, such as uses flow chart and diagrams for teaching purposes. Data analysis was conducted using SPSS for Windows (version 17.0). The first objectives which is to determine students’ understanding level was described in percentage based on the answers in questionnaires. The second objective which is to determine the effectiveness of various teaching methods was described Kruskal Wallis and Mann Whitney test since the data is not normally distributed. The third objective in the meanwhile is to determine the association between lecturers self-preparation with lecture delivery effectiveness. These were described by Spearman Correlation test. The fourth objective, which is meant to find out the relationship between effectiveness of lecture and students’ academic performance during 1st year 1st semester, was described using the Spearman Correlation test. A p- value of less than 0.0005 was considered to have significant difference. RESULTS The findings for students’ understanding level after lecture delivery shows 87 (52.4%) of the 166 respondents have good understanding level. Only 69 (41.6%) have moderate, 7 (4.2%) have very good and 3 (1.8%) have poor understanding level. Level of knowledge Percent (%) N Poor 1.8 3 Moderate 41.6 69 Good 52.4 87 Very Good 4.2 7 Total 100.0 166 Students’ Understanding Level TABLE 2: Effectiveness of teaching N Degree of freedom Significant value 996 5 0.000 methods TABLE 3: Kruskal-Wallis test for effectiveness of teaching methods From Kolmogorov-Smirnov test, it shown the data is not normally distributed. By using Kruskal-Wallis test, at degree of freedom, F (5, 990), significant value, p is less than 0.0005. As p <0.05, this indicates that there is a highly significant difference between the 6 groups of teaching methods. In order to know where the significance lies, comparisons between groups of teaching methods are done by the use of nonparametric Mann-Whitney Test.

On the other hand, there is no significant difference among teaching methods like assignment, case study, individual/group presentation, tutorial and problem base learning. Teaching Methods Median Assignment 22 Tutorial 18 Case Study 17 PBL 14 Individual / Group presentation 13 e-SPIN 2 TABLE 5: Median value for each teaching method Based on the table above, assignment has highest median of 22 among the rest of the teaching methods. While e-SPIN gives the lowest value, which is 2. Hence, assignments are the most effective teaching method while e-SPIN is the least effective teaching method. Lecturers’ self preparation TABLE 6: Sig. Value (2-tailed) r value <0.0005** 0.263** Spearman Correlation between lecturers’ self preparation and lecture delivery effectiveness The r value is positive with 0.263 and p<0.0005. The p value is <0.05, hence null hypothesis is rejected where there is a correlation coefficient of population between students’ understanding level and lecturers’ self-preparation. There is a positive correlation between students’ understanding level and lecturers’ self-preparation. The strength of correlation is weak (r = 0.263). Effectiveness of lecture delivery TABLE 7: Sig. Value (2-tailed) r value 0.819 0.018 Spearman Correlation between effectiveness of lecture and students’ academic performance during1st year 1st semester From the table above, the finding for association between effectiveness of lecture and students’ academic performance shows that r value is positive with 0.018 and p = 0.819. Since p >0.05, it is not significant different between effectiveness of lecture and students’ academic performance during 1st year 1st semester. So, there is no correlation between effectiveness of lecture and students’ academic performance during 1st year 1st semester. DISCUSSION Based on the bar chart, for objective 1 which is to determine students’ understanding level after lecture delivery, it shows that most of the students have good understanding after the lecture delivery and there is none of the students with very poor understanding of lectures. This proves that students have the perception that the lecturer’s delivery of lecture is effective. Eble (1971) pointed out that there are five components of effective teaching as perceived by the students. They include teacher must use an analytic/synthetic approach, well organized, teacher-group interaction, teacher-individual students interaction and dynamism/enthusiasm manner. Smith (1980) contributed a checklist for good teaching by including test prerequisite skills, provides feedback to the teacher, adopts to individual differences, provide feedback to the students, flexible, promotes active student learning, motivates students and clear and wellorganized. All these factors are vital for the understanding of students towards lectures delivered. From the Kruskal Wallis test performed for objective 2, there are highly significant differences between the six groups of teaching methods. From the Mann Whitney test performed, there is a significant difference between e-SPIN and the other five groups of teaching methods. From the median value obtained to determine the effectiveness of various teaching methods, students and lecturers think that assignment is the most effective method of teaching. However, the lecturers and students think that e-SPIN is not an effective method of teaching. Assignment prepares students to become effective and efficient life-long learners which is an absolute essential in a profession where new types of problems and new information surfaces with almost logarithmic expansion. The old educational truism states that half of what the students learn in school will be wrong or outdated by the time they are in the real world, and no one knows which half that is. This means that the teachers working with the students should not provide the students with what they feel is the information students need in their studies nor give them reading or study assignments. The students must learn how to decide on what they need to learn and to seek out appropriate learning resources, using the faculty as consultants (often called "resource faculty" in problem-based learning) as well as books, journals, online resources and other experts. This means that assignment is not teacher-centered, the teacher does not direct what students should learn or what resources they should use. Instead the teacher designs and provides the problem simulations and problem experiences that challenge the students to learn what is expected in the curriculum. Using facilitatory teaching skills, the teacher guides them in their work with the problem as they develop problem-solving skills, identify what they need to learn and develop self-directed learning skills. The teacher in this role is usually referred to as a "tutor" and needs to be well trained for this role. In addition, they must reflect on how their new learning relates to prior problems and prepares them for future problems. This important step helps convert procedural knowledge gained through problem solving into declarative knowledge for use and recall with other problems in the future. Through assignments, students are able to access, study and integrate information from all the disciplines that might be related to understanding and resolving the particular problem they are working with, just as people in the real world must recall and apply information integrated from diverse sources in their work. This allows the problem to be the organizing focus for student learning better ensuring the recall and application of that information from various relevant fields in their subsequent work with problems in their life and careers. Assignments require that students are active learners, responsible for their own learning and have adequate time for self-directed learning. Assignments also enable students to work in groups and improve in their social, interactive and leadership skills. Besides, assignments give life sciences graduate students direct practice in the statistical reasoning skills needed to choose appropriate procedures for analyzing data from their research studies. The course gives students practical experience by focusing on the analysis of data from actual biomedical research studies. Student evaluations indicated that this course improved the students' ability to understand and apply statistical methods in their research. Written assignments help in organization of knowledge, assimilation of facts and better preparation of examinations. It emphasizes on individual pupil work and the method that helps both teaching and learning processes (Kochhar 2000). Fully explain assignments are given so that students know how to best prepare. When the inevitable question, "Will we be tested on this?" arises, students are able to include not only a "yes" or "no," but a "because" (Shea A 2009). However through online learning such as e-SPIN, student assessment and feedback is limited. Many, if not most, of today's web-based training programs are too static, with little if any interactivity. e-SPIN also contain potential for the lack of interaction with classmates and lecturer. Online learning limits the amount of public speaking practice gained from in-class presentations and discussions, something that is naturally built into a traditionally structured class. e-SPIN also has limited access to lecturer which involves sitting down with lecturer to discuss a topic from class or reasons for a certain grade . Through online learning, students tend to miss out on non-verbal communication which is is as important, if not more important than verbal communication, and it’s hard to see non-verbal communication online. Similar to the need for face-to-face conversations with a teacher, non-verbal cues are impossible online, and can be just as communicative as actual words. Overall, e-SPIN is not an effective teaching method as perceived by the lecturers and students as unmotivated learners or those with poor study habits may fall behind. The lack of familiar structure and routine may take getting used to and students may feel isolated or miss social interaction. Besides, instructor may not always be available on demand. Slow or unreliable Internet connections can be frustrating and some courses such as traditional hands-on courses can be difficult to simulate. For objective 3, based on Spearman Correlation test performed to determine association between lecturers’ self-preparation and lecture delivery effectiveness, there is a weak positive correlation between lecturers’ self-preparation and lecture delivery effectiveness. Self preparation of lecturers involves many aspects either emotionally, theoretically or practically. Lewis, et al. (1988) discussed about the characteristics of effective large-class instructors which include enthusiasm about the subject, knowledge of the subject and the ability to communicate this knowledge, cares about the progress and welfare of the students, dares to discipline (govern) to eliminate unnecessary talking, has a sense of humour, uses a variety of instructional strategies, interacts with students during, as well as before and after class, and has confidence in him/herself and what he/she is doing. These are all examples of self preparation that is done by an effective lecturer. Colker (2008) reported that teachers claimed there were four characteristics of an effective teacher which include having a sound knowledge of subject matter, take personal interest in each student, establish a caring or loving or warm atmosphere and finally to show enthusiasm with students. Colker (2008) identified the twelve characteristics of teachers that children believe are integral factors to effective teaching. There are passion, perseverance willingness to take risks, pragmatism, patience, flexibility, respect creativity, authenticity, love of learning, high energy and sense of humour. Self-preparation of teachers in US tends to increase personal teaching efficacy (Hoy & Woolfolk 1990, Wenner 2001). Cox and Rogers (2005) described a well-prepared lecture as an interactive experience that actively engages students in the process of learning and can support diverse student learning. When the objective is to communicate basic facts, introduce intitial concepts or convey passion about a topic, a well prepared lecture is very useful (Cox & Rogers 2005, Gleitman 2006). Horngren (1963), pointed out that good teachers possess three crucial characteristics. These are knowledge of the subject matter, adequate preparation and enthusiasm. He defines preparation as being “always ready”. Sheffield (1974) listed out the characteristics of effective teachers most often mentioned which include master of his/her subject or competent, lectures well prepared and orderly, subject related to life or practical, students’ questions and opinions encouraged, enthusiastic about his/her subject, approachable, friendly or available, concerned for students’ progress, has a sense of humour or amusing, warm, kind, sympathetic, and teaching aids used effectively. Based on another Spearman Correlation test carried out for the last objective which is to determine the association between effectiveness of lecture and students’ academic performance during 1st year 1st semester, there is no correlation between effectiveness of lecture and students’ academic performance during first year first semester. Effectiveness of lecture delivery does not influence students’ academic performance during the first year first semester study. This might be due to students not depending solely on the lecturer’s lecture delivery and lecture notes. Students may find other sources to perform academically besides lecture note only which is also known as active learning. Active learning refers to situations where students are involved in the educational process instead of passively listening to lectures (Hermanson 1994). Besides, it might be the students responsibility if they do not perform well in their academics even if the lecturer had delivered their lectures effectively, for example the students not paying full attention during lecture or being absent for a particular lecture. Cox (1994) suggests that, ideally lectures are only there to lay foundations, show the way, and ease the passage, as the student works through the subject. Since the result obtained proves that problem based learning is an effective teaching method, there tend to be a difference between PBL and non-PBL students in their academic performance which is not dependant on lecture effectiveness solely. Nolte et al. (1988) found that use of reserve material went up. Blumberg and Michael (1992) found that PBL students were more likely to use textbooks and other books and informal discussion with peers than did non-PBL students, who were more likely to rely on lecture notes.
