he current development technologies provide a huge amount of information within a minute; information was obtained in different formats. In this scenario, access, organize and using appropriate printed and electronic information resources becomes an essential requirement in the contemporary era. In the context of University education, writing of assignments are an integral part of the learners, to expand knowledge in specific disciplines, engage in learning and research. In the meantime, writing and organizing the references, in particular referencing style plays a significant role in the academic assignments writing process. If it's used appropriate reference style, that particular document or research becomes high-quality reference and helps to avoid plagiarism. But it is a challenge for undergraduate in the present information era, where the information is abundant. According to Mashroofa (2009) "Information, overload is a frequent complaint within these environments. Because of the complexity of these environments, undergraduate face with diverse and abundant information choices in their academic studies" taking into consideration of these factors undergraduates should be guided to acquire proper skills for using reference system. In this background, this study aims to evaluate the knowledge and for writing different referencing style in the final year esthetic Studies Undergraduates assignments at Eastern University, Sri Lanka. Although there are different reference management software like End Note, Mendeley etc; it is difficult to use this software in aesthetic studies assignments and the medium for conducting all academic programme in tamil at Swami Vipulananda Institute of Aesthetic Studies . The available software does not support the local language properly. Moreover, available literature on various referencing styles is also in English, by which the students in aesthetic studies struggle to write the references in their assignments and reports. Therefore students have to be trained for different referencing styles manually. The undergraduate follows esthetic studies at the Swami Vipulananda Institute of Aesthetic Studies, which was merged as a higher education institute with Eastern University, Sri Lanka officially in 14 th

Referencing style has been a subject of concern to an undergraduate in most of the Aesthetic studies. Also, the lack of appropriate knowledge in writing referencing style in assignments has become worrisome for all undergraduate. It was observed while the undergraduate students submit assignments throughout their study programme. Therefore, the study intended to carry out on evaluating their Skills for writing Referencing Styles in the Assignments of Aesthetic Studies Undergraduates.

The objective of the study is ? To investigate the use of reference skill of aesthetic studies undergraduate in their assignments ? To examine the use of referencing styles for different formats of information sources (Books, Periodicals, and Nonprint sources) in Undergraduates assignments. ? To suggest the remedies for undergraduates to write the reference more effectively.

Descriptive survey method has been used for this study and observation chart has been used as the data collecting instrument. The target population included in the study was all final year students of the academic year of 2009/2010, enrolled in Swami Vipulananda Institute of Aesthetic Studies, Eastern University Sri Lanka. The sample size calculated as per Barletta. (2001). accordingly, the sample size for the present study is 75 as the population size is 164. However, only 60 students have responded for this study. Therefore the response rate of present study is 80 %. The sample was selected through stratified random sampling. The undergraduates' population was satisfied into two categories, according to their field of study and gender.

In this study, a pre-observation (pre-test) carried out with undergraduate's assignment in 2014 October. The researcher conducted a workshop on different referencing styles consisting of three sub topic. The programs conducted for two days and at the end of the program (after one month of a program) a post observation (post-test) was carried out with undergraduates' new assignments. The collected data were analyzed using SPSS statistical software for descriptive statistics.

Since the aesthetic studies undergraduate mostly use books, periodicals and non-print sources for their assignments, the data analysis was limited only to three categories such as referencing style for the format of Books, Periodicals and Non print sources. According to the pre-test, it was noted that the highest percentage of aesthetics studies undergraduates (56.67%) were not familiar with for the referencing style for books. Likewise, the Undergraduates were also not familiar in referencing styles of non-print sources and Periodicals. In the pretest, 15% of the students wrote appropriate reference for non-print sources and only 26.66% of the students wrote an appropriate reference periodical. Overall performance in writing different reference style in undergraduates' assignments was not in the satisfactory level that is Majority of students (71.67%) was not familiar with the use of reference in an appropriate way. The results are given Table 01.

The performance levels of writing referencing styles in undergraduate assignment after the post observation are given table 02.

The result of post-test indicates that the skills for writing different referencing styles in the assignments of aesthetic studies undergraduates after conducting two days' workshop were slightly increased in all categories. The in-depth analysis showed that the overall performance of appropriate referencing style level was increased by 6.11%, which ranges from 2.16% to 8.33%. The writing skill referencing style for periodical was increased by 6.67%, for non-print sources it was increased by 2.16%, and for books it was increased by 8.35%. However, the overall increase did not exceed the 50%, but it was only 34.44%. In the comparison of preobservation and post-observation for writing referencing style in their assignment is given in table 03. According to this study, the overall average level in the usage of referencing style in Undergraduates assignment was at needs improvement level. Further, the study reveals that due to the two days' workshop knowledge about the usage of referencing style at the assignment of aesthetics studies undergraduates was slightly increased in all categories. But those levels are not even in a satisfactory level. Therefore the skills for writing referencing styles should be improved in an appropriate way among the aesthetic studies undergraduates from in their first-year studies. Hence, the following recommendation can be made to develop the undergraduate referencing style.

The Institute should plan and arrange short term awareness program and workshop at regular intervals to develop the referencing skill among students. They need training especially on non-print sources referencing and periodical reference style. Therefore Institute should consider the time duration and the length to the program to be relevant to Undergraduates.
