                       AIMS AND OBJECTIVES OF THE PROGRAMME 

 AIMS:

 The Facuty of Science, Mahatma Gandhi University and Board of Studies in Chemistry (UG) recognizes that curriculum, course content and assessment of scholastic achievement play complementary roles in shaping education. The committee is of the view that assessment should support and encourage the broad instructional goals such as basic knowledge of the discipline of Chemistry including theories and techniques, concepts and general principles. This should also support the ability to ask physical questions and to obtain solutions to physical questions by use of qualitative and quantitative reasoning and by experimental investigation. The important student attributes including keen observation, curiosity, creativity and reasoned skepticism and understanding links of Chemistry to other disciplines and to societal issues should be given encouragement. With this in mind, we aim to provide a firm foundation in every aspect of Chemistry and to explain a broad spectrum of modern trends in chemistry and to develop experimental, computational and mathematics skills of students. The programme also aims to develop the following abilities: 

1. Read, understand and interpret chemical information – verbal, mathematical and graphical. 

2. Impart skills required to gather information from resources and use them. 

3. To give need based education in chemistry of the highest quality at the undergraduate level. 

4. Offer courses to the choice of the students. 

5. Perform experiments and interpret the results of observation. 

6. Provide an intellectually stimulating environment to develop skills and enthusiasms of students to the best of their potential. 7. Use Information Communication Technology to gather knowledge at will. 

8. Attract outstanding students from all backgrounds. 

 OBJECTIVES:

The syllabi are framed in such a way that it bridges the gap between the plus two and post graduate levels of Chemistry by providing a more complete and logical framework in almost all areas of basic Chemistry.
