But with the arriving of new technological tools such as like laptop, multimedia projector and computer software, some university lecturers are using those tools for their lectures. The objective of this study is to determine if there is a significant difference of achievements and attitudes between students under traditional teaching and under multimedia assisted teaching. A class of 50 students in social statistics with the use of multimedia assisted teaching and a class of 50 students in social satistics with the use of the traditional methods of teaching at the university of Kelaniya were the sample of this study.

Influence of paddy farming behavior on human health in Sri Lanka
(Culture, Globalization and the Developing World, 2nd ICSS, 2013) Balasooriya, N.
Paddy farming in Sri Lanka can be divided into three schemes according to the source of water availability for farming. Scale of cultivation depends on the schemes. Most of the paddy farmers try to achieve desirable outputs but they are least concerned about the undesirable byproducts of their production processes. In the paddy farming belt in Sri Lanka, kidney and teeth diseases have been spreading significantly. This study is an attempt to find out the influence of paddy farming behavior on human health and how it varies within different cultivation schemes. Then this study has achieved the objective of examining the magnitude differences of influence of paddy farming on human heath with in the schemes of cultivation based on monetary value estimation. Both primary and secondary data were used in the research. Primary data was collected through structured interview method. Using the mix method of stratified and cluster random sampling, 150 paddy farmers were selected as a sample for the interview from the three schemes of paddy cultivation. The monetary value estimation of this negative effect was existed by using the mathematical formulas which were formularized based on non-market evaluation methods of cost of illness and lost output approaches. Further one-way ANOVA and chi-square test were utilized to achieve the objective of the study. According to the analysis, it was indicated that the Influence of paddy farming behavior on human health is vary within cultivation schemes. Further the result shows that the contribution an individual paddy famer for the cost of negative influences on human heath was allocated as 52012.55 LKR and 23218.06 LKR in major irrigated scheme and minor irrigated scheme respectively.
Informal Economic Activity of Women in Sri Lanka
(University of Kelaniya, 2007) Balasooriya, N.
The concept of the informal sector has been debated since its "discovery "in Africa in the early 1970's. Now. the Informal Economy has been variously described in the literature like. Unorganized Sector. Unregistered Economy. Third Economy, Parallel Economy. Shadow Economy and Underground Economy etc. Despite this description or perhaps because of them, the dc1inition of Informal Economy has remained elusive if not controversial. So, we can say it is a dynamic process which includes many aspects of economic and social theory. However Fifteenth International Conference of Labour Statisticians in 1993 defined the informal economic sector as follows: the informal economic sector is regarded as a group of household enterprises or unincorporated enterprises owned by household that includes, informal own- account enterprises and enterprises of informal employers. Informal employment is generally a larger source of employment for women than for men in the developing countries. 60 per cent or more of women workers in the developing countries arc in informal employment. In sub- Saharan Africa 84 per cent of women non- agricultural workers are informally employed. In Asia the proportion of women and men non-agricultural workers in informal employment is roughly equivalent. Although participation of women's labour force rate is lower than men's, the limited data available point to the importance of women in home based work and street vending in developing countries. 30-90 per cent of street vendors, 35-80 per cent of all home based workers and 80 per cent or more ofhomc workers arc women. Sri Lankan informal sector is also similar. It is economic activity that is neither taxed nor monitored by government and is not included in that Government Gross National Product (GNP) as opposed to a formal economy. So I used primary data and secondary data for this study. Primary data was taken from Stratified Random Sample by using questionnaire and observation. In this paper will be discussed the real status of informal economic activity of women in Sri Lanka. ·
