To collect data, questionnaire, focusing on attitude from peers’ perspectives, whereas the test was given to identify students’ level of understanding the content of biology were employed. As the students were given test after finishing each chapter they learnt. The finding shows that attitude of the students changed after using the inquiry-based learning.
