The assessment instrument is an integral part of an assessment process in
learning. Assessment instruments include tests and a grading system. The
assessment instrument is designed to determine the level of understanding of
students after learning a competency. Achieving the real goal of learning
chemistry requires the use of assessment instruments that not only include rote
memorization and understanding, but also requires assessments that train
thinking ability. Assessment instruments that are well designed and in accordance
with the level of thinking ability will be able to improve students' thinking capacity,
especially critical thinking. Problem Solving-based learning is one of the learning
methods recommended by the government (Permendikbud, 2013), where the
learning process emphasizes the independence of students in solving problems.
The assessment instrument was developed to measure students' critical thinking
skills based on 12 indicators of critical thinking according to Ennis (2011) and
the characteristics of CPS according to Vidal (2010), namely finding problems in
general, finding facts, clarifying problems, expressing opinions, finding solutions
and implementing them.
This research aims to develop an assessment instrument for students’
critical thinking ability based on CPS on valid and reliable stoichiometry material
and to find out differences in the measurement results of students' critical thinking
ability on stoichiometry material in high, medium and low schools.
The subjects in this research were the students of class XI IPA SMA Negeri
1 Bengkalis, SMA Negeri 2 Bengkalis and SMA Negeri 2 Bantan, each consisting
of 25 students. The sampling technique was purposive sampling technique, where
the sample selection was according to the researchers' considerations. The
research approach used to develop assessment instrument products was
development which refers to the type of Research and Development (R&D)
research adapted from the Borg & Gall Model.
The instrument for assessing critical thinking skills developed has
characteristics, namely that it is declared valid in terms of content validity, with
Aiken's (V) validation values ranging from 0.88 to 0.94. In the construct validity,
there were 11 valid items out of the total. The questions developed have met the
reliability requirements with the Cronbach alpha coefficient value greater than
0.6, namely 0.795. The difficulty level of the questions was in the easy, medium
and difficult categories, namely 27.3% of the items in the easy category, 45.4% of
the items in the moderate category, and 27.3% of the items in the difficult
category. And the distinguishing power of the questions is in the very good, good
and sufficient category. The percentage of distinguishing power of the questions
was obtained 27.2% of the items in the very good category, 36.4% of the items in
the good category and 36.4% of the items in the sufficient category.
Based on the consideration of the researcher and the discussion with the
supervisor, the questions that were tested on the students were 10 items, this was
xvii
seen from the achievement of the learning indicators on the stoichiometry
material and the allocation of the planned time for the test. The assessment
instrument for critical thinking skills based on CPS on the readability aspect of
the good category, the time adequacy aspect of the good category and the
feasibility aspect of the good category. The results of measuring the critical
thinking ability based on CPS stoichiometry material on 75 students at high,
medium and low schools indicate that there are very significant differences in
students' critical thinking skills where the differences in the high, medium and low
school categories with a significance value of 0.003
