The education paradigm undergoes a shift
that leads to constructivist learning, which initially from
teacher-centered becomes student-centered.
Constructivistic learning models emphasize the sincerity
of students in shaping the knowledge that will be
absorbed. One constructivist based learning method is
the 5E learning cycle, which will be applied in
instructional media in the form of student worksheets for
vocational high schools. This development research aims
to develop worksheets products in simple harmonic
motion materials that are valid for vocational high
school technology and engineering programs. The
research design refers to the research and development
of Borg and Gall until the stage of product testing. Data
were collected by expert validation questionnaire,
readability questionnaire, convenience questionnaire,
attractiveness, benefit and test of student learning
outcomes. The product of the development was tested at
SMK Negeri 1 Seputih Agung, Central Lampung
Regency to find out its effectiveness aspects using a non-
equivalent experimental design pretest-posttest control
group design. The statistical test of the independent
sample t-test was used to test the truth of the hypothesis
about the difference in normalized gain values of the
experimental class and the control class, while the
hypothesis of the average pretest-posttest difference was
tested by paired sample t-test. Learning in the
experimental class uses development product worksheets
while the control class uses conventional worksheets.
This study provides results in the form of validation of
media experts getting 100%, material experts at 100%,
and linguists by 100%. The average normalized gain of
the experimental class is 0.4645, higher than the control
class of 0.4281. The level of product attractiveness is very
high at 80.87%, the high facilitation aspect is 77.86%
and the benefit aspect is very high at 80.36%. Other
results obtained that students are eager to do activities
that can get skills that can be used for everyday life.
