| dc.description.abstract | The purpose of this research is to provide lab practice with pure validity, to
know the students’ practice activity and to motivate them to study after using the developed
Physics lab practice. This research is the kind of development of Physics lab practice using
4-D learning instruments. Data was obtained using logic validation, observation, and
questionnaire. The logic validation value was obtained by the assessment of the virtual lab
instruction which presented 2,78 so that it is said to be safe and is good to be used as
development trial. Based on the development trial, it was concluded that the students work
result by using the instructions on the Physics Virtual Laboratory-Based, either on the
ability of observing and making note or on the ability of interpreting the result and drawing
conclusion was good. Students’ motivation is classical for 92,45% so that it can be inferred
that they were highly motivated during the practice. | en_US |
