摘要：The research focuses on the development and validation of an integrated
assessment instrument to assess students’ analytical thinking skills and chemical
literacy in chemical equilibrium. The research consists of 5 phases ie analysis,
design, development, implementation, and evaluation. The research participants
were 174 students of grade 12th senior high schools in Yogyakarta, Indonesia. The
participants were selected using stratified random sampling. The Integrated
assessment instrument to assess students’ analytical thinking skills and chemical
literacy consists of 20 open-ended multiple-choice questions developed from 12
integrated indicators. Expert validation result shows that 20 questions are declared
valid with Aiken's V value greater than 0.86. The result was collated and coded for
analysis with Rasch model approach. 3 items (15%) were included in the very
difficult category, 3 items (15%) were included in the difficult category, 8 items
(40%) were included in the moderate category, 5 items (25%) were included in the
easy category, and 1 question (5%) was included in the very easy category. It turns
out that this instrument is capable to measure students’ analytical thinking skill and
chemical literacy.
