were analyzed with SPSS. It is said there is no difference between pretest and posttest if the value of
sig. > 0.05. Based on the test results, the readiness value in the control class for the pretest and posttest
was no statistically significant difference because of the sig value. 0.108> 0.05. The value of skills in
the control class for the pretest and posttest also were not statistically significant differences because of
the sig scores. 0.139> 0.05.
The treatment of the experiment class is students doing practical work modelling with proteus which
is help by practical modules for 15 minutes. The result is evaluated by writing descriptive statistics.
Paired t test data for the experimental class were analyzed by SPSS. Based on test results, shows the
value of sig. 000 <0.05 which means there is a statistically significant difference between the pre-test
and post-test readiness values. Practical skill scores, sig. 000 <0.05. It is mean that there is a statistically
significant difference between the scores of the pretest and posttest skills.

type is used because the research using one independent variable and
two dependent variables.
The aim of this analysis is to find out whether there is a statistically significant
difference in posttest scores (readiness and experiment skills values) between the experiment class and
the control class.
The difference in pretest scores can be controlled because it has the same or
homogeneous variants. Hotelling T

test results are presented in the Table 3.
