The purpose of this study is to track the changes in the student’s attitude towards learning chemistry lessons at the higher secondary level during their higher secondary learning years. ATCLS (Attitude towards learning chemistry lessons scale) was administered on 50 random samples of Sacred Heart higher secondary school, Iruppukurichy, cuddalore Dt, Tamilnadu. It was hypothesized that there is no significant difference in the attitude towards learning chemistry lessons among students during their higher secondary learning years. The data was collected before the start of the course, as they entered class 11, and again the same tool was administered on the same sample when they completed the course, as they completed learning chemistry in class 12. On computing the data, it is alarming to note that the student’s attitude towards learning chemistry is in decline as they move from one level to the other. This study also suggests Chemistry teachers focus on the affective dimension of chemistry education.
