Key word : ADI Model, Contextual Approach, Critical
Thinking Skills
The educational process with a focus on critical
thinking skills competencies can produce human resources who have skills needed
in the today and in the future workforce. In this context, this study aims to
produce learning instrument by using Argument-Driven
Inquiry (ADI) model with Contextual
Approach with a valid, effective, and practical to improve students'
critical thinking skills. This research
was conducted in two phases, the development stage of learning materials
adapted to the 4-D model and wide implementation of trials phases in six
classes using the one-group pre-test
post-test design . The research sample is class VIII Semester 2 of the
2019/2020 academic year. The research methods used are validation, observation,
giving questionnaires, and tests of critical thinking skills. The
research instrument uses a validation sheet, observation sheet of
accomplishment, student activity sheet, constraint sheet, critical thinking
assessment sheet and student questionnaire response sheet. Data analysis uses
percentage of agreement, N-gain, wilcoxon matched pairs test and Kruskall Wallis test. The result of the analysis
of research: (1) The validity of the
learning materials developed in terms of the results of content validation in
the valid category and the construct validation in the valid category is
obtained a percentage of agreement of 91.09%, (2) Effectiveness of learning materials viewed on: (a) The response of
students are very good, (b) Students' critical thinking skills increase with a
high level of increase in categories, which was statistically significant at
alpha 5% and are not different (consistent) in the six classes; (3) The
practical of learning materials viewed on: (a) Feasibility of instructions have
very good category, (b) Student activities have active category . The conclusion of this
research the develop learning materials
by using Argument-Driven Inquiry (ADI) Model
with Contextual Approaches are eligible (based on criteria of validity,
effectiveness and practicality) to improve students’ critical thinking skills.
