dc.description.abstract | The goals of this research were: (1) to describe the difference of study outcome
of students between use problem based learning model with portofolio
assessment and conventional learning on physics learning at junior high school;
(2) to describe student activity use problem based learning model with portofolio
assessment on physics learning at junior high school. The type of this research
was pure experiment research. Basically, the research methodology of this study
to different between experiment class and control class. Data collection method
of this research used observation, interview, test, and documentation. The data
analysis used: (1) data to determine learning outcomes derived from post-test of
the experimental class and control class, with t-test statistic to analyze; (2) the
percentage student’s activities. The score value of t-test is 4,971 greater than ttable
and its mean that there were difference of study outcome . The percentage
of students learning activities at first meeting was 72,2%. In the second meeting,
percentage classically less than the first meeting it was 78,7%. The average of
students activities percentage was 75,45%. | en_US |
