Pengembangan E-LKPD Berbasis Pendekatan Stem (Science, Technology, Engineering And Mathematic) Menggunakan Liveworksheets Pada Materi Sifat Koligatif Larutan Kelas XII SMA/Ma
This study aims to produce a valid E-LKPD based on the STEM approach
using liveworksheet material colligative properties of the solution and knowing the
teacher's assessment and student user responses to the E-LKPD. This study uses the
ADDIE development model. Data analysis techniques used validation questionnaires
and user response questionnaires. The trials were carried out on a small scale
consisting of two stages of trials, namely one-on-one trials with 3 students and
limited trials consisting of 2 chemistry teachers and 20 students. The results showed
that the development of E-LKPD based on the STEM approach used liveworksheets
on material colligative properties of valid solutions based on the assessment of
material validation and media validation from the aspects of content feasibility,
STEM characteristics, language and presentation for material validation with a total
average percentage of 94.27% and feasibility of size, cover design and content design
based on media validation with a total average percentage of 96.27%. The teacher's
assessment of the STEM approach-based E-LKPD development resulted in a total
percentage score of 94.70% and student responses of 87.47% with very good criteria.
