In this study, multiple choice and theoretical questions during the 10-year period of INTER
NATIONAL JUNIOR SCIENCE OLYMPIADE(IJSO) were analyzed based on the behavioral area (problem
type) and content area (evaluation content factor). As a result of dividing the behavior area into knowledge,
application, and reasoning and calculating frequency, the ratio of knowledge area was highest in
multiple-choice questions. In the theoretical items, the ratio of application area was the highest. Categories
with the most frequency in the content area was animal structure and function, followed by cell and meta
bolism, ecology, genetics and evolution, and structure and function of plants. Compared with KJSO selection
test, IJSO had a somewhat higher proportion of reasoning areas and no significant differences in content
areas. In the 2017 and 2018 IJSO experimental questions, questions about conducting experiment and
interpreting data were the most common, followed by questions about whether or not they understood the
principles of experimentation. Other questions were to ask the ability to transform the data, and what results
would come out under certain circumstances. Taken together, what IJSO calls for is knowledge of full range
of biology, ability to perform experiments and reasoning skills.
