Abstract :
The objective of this research was to know the effect of problem based
learning and learning starts with a question method against the students learning
achievement about of momentum and impuls materials. This research was
conducted at SMA Negeri I Labuan Haji in the school year 2017/2018. This
research was experiment research. The population of this research was whole
students at X class consisted of five classes. The sample was determined using

5 class as the control group. The planning of this research that used is posttestonly control design. The data collection technique uses achievement test. Then,
the data is analyzed using t test. Based on the data analysis resulted tcount is 2,239
and ttable is 2,015 until tcount > ttable (2,239 > 2,015) it means that Ho rejected, so the
conclusion is there was effect of problem based learning and learning starts with
a question method against the students learning achievement about of momentum
and impuls materials at the X graders of SMA Negeri I Labuan Haji in the school
year 2017/2018.
