Improving Students’ Scientific Ability through Lesson Study-based Mathematics Learning
MetadataShow full item record
Students’ scientific ability is the main concern of every lesson carried out by teachers in Indonesia nowadays. Learning process based on students’ scientific ability was designed such that the students may construct the concept through observation step (to identify or find the problem), design the problem, give the hypothesis, collect the data, analysis the data, make the conclusion and communicate the funded concept. Therefore, improving students’ scientific ability will students’ ability in problem solving and develop students’ positive characters. In this study, three students from 7th grades SMP Negeri 1 Jember were randomly selected to observe their scientific ability. The observation was focused on how they were observing, questioning, associating, experimenting, and networking to solve some problems related to mathematics. Periodic observations were conducted during the open classes, one of the stages in the lesson study procedure, in each cycle conducted by the lesson study team members consisting of one teacher and three observers. There was an improvement in scientific ability from three selected students during the third open class compared to the first and the second open classes after reviewed collaboratively by the lesson study team members. In the first open class, two students couldn’t solve the problems correctly because they didn’t comprehend what was the given and which was asked in the problems. In the second open class, three students were able to solve the problems correctly but they couldn’t make the conclusion and communicate that result. However, in the third open class, three students could solve the problems by observing, questioning, associating, experimenting, and networking correctly. Therefore, it can be concluded that there was an improvement in students’ scientific ability after participating in the lesson study-based mathematics learning.
