SUMMARY
MASRUROTUL KHOIRIN NAJAH, NIM. 2110247762, Web-Based Five-Tier
Diagnostic Test Development for Identifying Students' Misconceptions and
Critical Thinking Abilities in Hydrocarbon, supervised by Jimmi Copriady and
Roza Linda
Misconceptions experienced by students are closely related to their critical
thinking abilities. Critical thinking is the ability to logically and deeply analyze
information, evaluate evidence and arguments, and make rational and objective
decisions or conclusions. It is a higher-order thinking skill that plays an essential
role in learning, problem-solving, and decision-making. To address the
emergence of misconceptions, diagnostic actions are needed to detect students’
misconceptions. One method of diagnosing misconceptions is by developing an
assessment instrument to be used after the learning process. The five-tier
diagnostic test is an advanced version of the four-tier multiple-choice diagnostic
test. One of the advantages of the five-tier multiple-choice diagnostic test is its
ability to diagnose students’ misconceptions more deeply. Additionally, webbased
diagnostic tests offer benefits over traditional paper-based tests.
This study aims to measure students’ misconceptions in hydrocarbon
compound material in terms of content, language, construction, and problemsolving
ability. It also aims to identify the characteristics (validity, reliability,
difficulty level, and discriminating power) of the items in the developed
instrument, assess user responses to the instrument based on readability and time
adequacy, and evaluate the extent of students’ misconceptions in the subject.
Furthermore, it seeks to determine differences in critical thinking abilities among
students from different schools.
This research uses the Research and Development (R&D) method,
employing the ADDIE model, which includes five phases: analysis, design,
development, implementation, and evaluation. The initial product was validated
by three chemistry subject matter experts and one media expert. The study
involved three senior high schools (SMAs) in Pekanbaru, categorized by
performance high, medium, and low level namely SMAN 1 Pekanbaru, SMAN 3
Pekanbaru, and SMAN 6 Pekanbaru. Data collection instruments included
validation questionnaires, user response questionnaires, and a multiple-choice
assessment instrument.
The five-tier diagnostic assessment instrument developed through several
stages of validation was found to be valid and reliable. The validity range before
revision was 0.925–1.0, classified as very high. After revision, it ranged from
0.967–1.0, indicating that the instrument was highly valid and met the minimum
criteria for acceptance. The website-based instrument design also showed
improvement, with both cover and content design achieving 100% validity. The
instrument was deemed reliable with a Cronbach’s alpha coefficient of 0.815. In
terms of difficulty level, 10% of items were categorized as easy, 83% as moderate,
and 7% as difficult. The discriminating power analysis showed that 56.7% of
xvi
items were categorized as excellent, 23.3% as good, 6% as fair, and 16.7% as
poor.
The percentage of misconceptions identified in each school was as follows:
low-performing school (20.91%), medium-performing school (26.07%), and highperforming
school (10.46%). A statistically significant difference was found in the
critical thinking abilities between students from the high-performing school and
those from the medium- and low-performing schools. However, no significant
difference was found between students from the medium- and low-performing
schools.
Based on the data, it can be concluded that the diagnostic and critical
thinking assessment instrument for hydrocarbon compounds is valid and reliable.
This assessment instrument can be used to accurately measure students’
misconceptions and critical thinking abilities in the topic of hydrocarbon
compounds.
