This research is motivated because educators still
use the direct learning model with the lecture method and
occasionally use power point media which is still teacher�centered, and the lack of physics learning resources in the
form of e-learning that can be accessed externally, anytime,
anywhere and the material content is very solid while the
learning time given in the classroom is only a little. The
objectives of this study are: 1) to develop guided inquiry�based e-learning with the help of the Edmodo application to
the 21st century students' skills 2) to produce guided inquiry�based e-learning assisted by the edmodo application to the
21st century skills of students that are valid, practical and
effective. This research is a development research with a
Research and Development (R&D) approach. The
development model used is the plomp development model
including: 1) Preliminary research, 2) development of the
prototype (Development of prototype phase) and 3) the
assessment phase (Assessment phase). Guided inquiry-based
e-learning with the help of edmodo applications on
temperature and heat and thermodynamics is very valid with
an average score of 90.44% with a content feasibility test
percentage of 86%, media feasibility 93.33% and language
feasibility 92%, where practicality by 94.67% educators and
students.
