This study aims to
determine the feasibility of developing problem solving-based e-LKPD on acid
and base materials to train critical thinking skills in students in terms of
validity, practicality, and effectiveness of developing problem solving-based
e-LKPD on acid and base materials to train students' critical thinking skills.
The model used is the 4D development model by Thiagarajan, Semmel, and Semmel
with restrictions only on the third stage, namely (1) Define Stage, (2) Design
Stage, (3) Development Stage, (4) Disseminate Stage. The research was conducted
at SMAN Jogoroto Jombang with the research subject of class XI students who
have less critical thinking skills. The data analysis technique used is to
determine the mode of validation results, calculate the percentage of student
response questionnaire sheet, calculate the percentage of student activity
observation sheet, and through the calculation of N-gain score. The results of
this study indicate that 1) content validity gets a mode number 5 with a very
good category, 2) construct validity gets a mode number 4 and 5 with good and
very good categories, 3) the average learner response questionnaire is 95% with
a very practical category, 4) the relevant activity of students is 93.32% and
96.65% with a very practical category, 4) the N-gain score is 0.91 in the high
category. Based on the results of the study, it can be concluded that the
developed e-LKPD is feasible to use because it meets the criteria of validity,
practicality, and effectiveness.
