Science learning emphasizes a culture of
critical thinking that is in harmony with technology, the environment, and
society, and refers to the future. Science learning utilizes more technology
called virtual laboratories. Online science learning using simulated PhET is in
line with current demands due to the Covid 19 pandemic, which is learning from
home online. This study aims to develop an online science learning tool based
on a scientific approach using a proper PhET simulation with valid, practical
and effective criteria to improve learning outcomes of elementary school
students. The device development model uses the 4-D model. The trial design
uses the One Group Pretest-One Group Posttest Design using 2 groups, namely the
Jagir 1 State Primary School group consisting of classes A and B and the
Wonokromo State Elementary School 3 group consisting of classes C, D, E with
each class of 20 students. Data collection methods using questionnaires,
observations, and tests. The results showed that: (1) The validity of the
device is valid by fulfilling the criteria of content and construct validity
very high, the level of readability is very high, and the level of difficulty
categorized as easy to understand; (2) Practicality meets the criteria, the
implementation of lesson plans categorized as good, the activities of students
categorized as good, The response of students categorized as good and obstacles
can be overcome; (3) The effectiveness of fulfilling the criteria in detail is
that there is an increase in learning outcomes in the competency of knowledge
statistically at 5% alpha, the average N-Gain is high, there is no difference
in the mean N-Gain in each class, and the learning outcomes in the competency
of knowledge, attitudes, and skills are classical completeness.
The results of the study concluded that
online science instrumet based on scientific approaches using PhET simulations
were developed appropriately with validity, practically, and effectiveness
criteria to improve learning outcomes of elementary school students.
