Conclude
Both of the observation sheets were given to two experts for content and face validation. Instrument
test results with a Cronbach's value 0.820 for the experiment skill instrument and 0.814 for the
instrument readiness in the experiment. This value is a measure of internal consistency and is considered
a measure of scale reliability [13].
Data of the readiness and experiment skills of students were analyzed using SPSS.
The Manova test
is used to perform data analysis assuming the data is normally distributed. It is used to determine whether
there is a statistically significant difference between the experiment class and the control class before
being treated.
Using the same assumption, paired t-test to determine whether there is a statistically
significant difference between before and after treatment is given.
The Manova test was also used to
determine whether there were statistically significant differences between the experiment and control
classes when differences in the pretest values were controlled. The normalized Hake equation is used to
determine the gain value to evaluate the effectiveness of the treatment [14].
