dc.description.abstract | The goals of this research were (1) to assess significant differences the cognitive
abilities of students before and after learning cooperative model through lesson
study with demonstration method physics at SMA, (2) to describe student’s
activities during application cooperative model through lesson study with
demonstration method physics at SMA, (3) to describe student’s responses after
application cooperative model through lesson study with demonstration method
physics at SMA. The kind of this research was quasi experiment with one group
time series design. The determination of where the research was purposive
sampling area. The sample of this research was the students of class X -4 at
SMA Negeri 1 Pakusari. Data were collected by observation, interview, test,
questionnaire and documentation. The data were analyzed by Independent
Sample T-Test, percentage of student’s activites, and percentage of student’s
responses. The result of analysis data were there was significant differences
before and after application cooperative model through lesson study with
demonstration method physics at SMA Negeri 1 Pakusari, student’s activities
was active with classical percentage Object 2 , and student’s responses with
