INTRODUCTION
Internet is a global network of computers linked
together over large distances.
Internet is a valuable source of information for students
looking for ideas for projects and assignments.
It allows students to broaden their academic
experience, access important information and
communicate to other within academic community.
Internet is also widely used by students for
entertainment, communication and other purposes.
Watching streaming video, online chatting, online
gaming, reading latest news, checking e-mail and etc.
Students experience significant academic problems as
they misuse internet.
Students have difficulty completing homework
assignments, having enough sleep, studying for exam, or
less exercise.
RESEARCH JUSTIFICATION
• Supporters of educational technology believe that internet will make a difference in academic achievement (Foltos,2002).
• There has been indication that some on-line users are becoming addicted to the internet which may result in academic failure (Brady,1996).
• Reports from University of Botswana Library state that students are not using the internet for academic purposes.
• Thus, our research can reveal the effect of internet on the academic performances of biomedical sciences students.
Assessing the positive impact - ‘An evaluation of the impact of Internet browsing on students’ academic performance at the tertiary level of education in Nigeria’ by O. Osunade (2003)
To evaluate the Internet as a knowledge acquisition tool and its impact on academic performance of students
The implication of internet toward academic performance in this study is positive-posttest results for the test group after internet access was significantly better than that of the control group.
LITERATURE REVIEW
Robert W. Kubey et. al(2001) -“Internet Use and Collegiate Academic Performance Decreasements”.
Survey was administered to 576 students at Rutgers University.
14 % of the total sample hurt occasionally, frequently, or very frequently due to Internet use.
Academically impaired sub group (N = 80), 40% - Internet use had kept them stay up late at night frequently or very frequently
42.5% -sometimes felt tired the next day due to their Internet use;
20% -occasionally, frequently, or very frequently missed class because of their Internet use.
This result indicates that academic performance might be impaired by heavier use of the Internet thus more to the negative impact.

MIND MAPPING
GENERAL OBJECTIVE
To study the relationship between
weekly duration of internet browsing
with the academic achievement of
first, second and third year Biomedical
students session 2008/2009.
SPECIFIC OBJECTIVE
To compare weekly duration of internet
browsing based on demography factors.
To find association between weekly duration
of internet browsing and CGPA.
To find association between duration of
internet browsing and hours spend on studies
weekly.
RESEACRH QUESTION & HYPOTHESIS
Question
Is there any relationship between
weekly duration of internet browsing
with academic performance of
Biomedical Science students year 1 - 3
session 2008/2009?
NULL HYPOTHESIS
HO :
1. There is no difference between weekly duration of internet browsing and demography factors.
2. There is no difference between weekly duration of internet browsing and CGPA.
3. There is no difference between duration of internet browsing and hours spend on studies weekly.
ALTERNATIVE HYPOTHESISHA :
1.There are differences between weekly duration of internet browsing and demography factors.
2.There is difference between weekly duration of internet browsing and CGPA.
3.There is difference between duration of internet browsing and hours spend on studies weekly.
METHODOLOGY
BACKGROUND Research conducted in UKM KKL branch involving FSKB Respondents involved are first, second and third year
undergraduate students from Biomedical Sciences Department.
Our group consist of 15 Biomedical Sciences third year students .
RESEARCH DESIGN
Research design that involved is cross sectional study. Our group use questionnaire for survey research.
SAMPLING METHODS
Target PopulationUndergraduate students of 1st, 2nd and 3rd years from Biomedical Science Department.
Sampel Population
Sampling method = Stratified random sampling. Undergraduate student in the sampling frame are divided into stratum according to the years. In each stratum, systematic random sampling is used.
The total number of the students would be 285.
Sample sizeSample size for the target population is calculated according to the formula below: n = X2 NP (1-P) ∆2(N-1)+X2(1-P)n = 3.84 (285) 0.5 (1-0.5) 0.052 (285-1)+3.84(0.5)(1-0.5) = 163.83 ≈ 164 subjectsAdd 10% of sample size in case there are respondents dropped out = 16 subjectsTherefore, Sample size = 180 students, where 60 students are chosen from each stratum.
MATERIALS AND METHODS USED
Questionnaire is used. There are 4 parts in
the questionnaire, which are
Part A : Demographic factors
Part B : Purposes
Part C : Respondents’ habits
Part D : Self-evaluation
STATISTICAL ANALYSIS
The research will be analyzed by using SPSS 14.0
The value for p is 0.05 corresponding to 95% of
confidence interval
The test that will be conducted are :
a) Independent t-test @ Mann-Whitney test
b) One-way ANOVA @ Kruskal-Wallis test
c) Pearson Correlation @ Spearman Correlation
