Abstract

This study aims to determine the effect of the experiment based environmental
on scientific attitude of the student and learning achievement on acidand
alkali subject. This study was quasi-experimental with Posttest-Only Control
Group Design. The sample consists of two intact group, experimental group
(learning by experiment based environmental method) and control group
(learning by traditional method) choosen by purposive sampling technic. Data
collection of scientific attitude using questionnaires and observation sheets,
while learning outcomes data collected by an objective test. Data analyzed
with descriptive statistic and non parametric statistic (Mann Whitney test).
The result show that student’s scientific attitude score of experiment group is
83.35 at very high category while the control group is 77.82 at the high
category. The average score of learning achievement 86.40 for experimental
group higher than control groupis 70.87. Beside that Mann-Whitney test
obtained sig. less than 0.05 (p <0.005). Thus, it can be concluded that the
experiment based environmental methods affect the scientific attitude and
student learning achievement on acid-base subject.
