Abstract:
The purpose of this research to develop an attitudes towards science questionnaire
and physical science process skills test instrument for students in junior high
school grades which are valid and reliable. The method used in this study is
research and development (R & D), with descriptive data analysis. This research
resulted in sixteen point statement of attitudes towards science and eleven
questions of science process skills in physics. The validity assessment of attitudes
toward science questionnaire instruments from judgment experts was 3.74 and
science process skills of physics test instrument was 3.66 in very high category,
while the items was also declared valid by the internal criteria validity. The results
of reliability for the physical science process skills test instrument with internal
consistency technique, using the KR-20 is 0.54 in medium category, while for the
attitude towards science instrument with Cronbach's alpha formula has a
reliability value is 0.83 in very reliable category, so they can be used as a junior
high school of physics tool assessment.
