Nowadays scientific reasoning is currently considered the central of
goal for development of 21st century people. Scientific reasoning is important
factor in science learning. This study aims to examine the effect of gender and
age influenced students scientific reasoning ability. This research was a
descriptive quantitative. The samples of the result were 200 students
(female=100, male=100) on first year physics education class of Tadulako
University in Palu, Indonesia with the age range was 18-20 years old. The data
on students scientific reasoning ability were taken from a multiple choice test
on scientific reasoning ability using Lawson Classroom Test of Scientific
Reasoning (LCTSR). LCTSR was administered to investigate students scientific
reasoning ability in six constructs namely (1) Conservation of Mass and Volume,
(2) Proportional Thinking, (3) Control of Variables, (4) Probabilistic
Thinking, (5) Correlational Thinking, and (6) Hypothetical-deductive Reasoning.
The results showed that no statistical difference between male and female on
scientific reasoning means scores were observed. The gender and age do not
significantly impact on students scientific reasoning ability for each
construct. In addition, the lowest mean score for the students reasoning
ability for both genders was control of variable.
