摘要：The present study aims to examine the implementation of a stepwise inquiry
approach to improving communication skills and scientific attitudes. Stepwise
inquiry comprises structured inquiry, guided inquiry, and open inquiry. The
variables measured were communication skills and scientific attitudes. The
construct used to measure communication skills involved written, verbal, and
social communication skills, along with scientific attitude indicators including
curiosity, openness of mind, objectivity, honesty in reporting results, responsibility,
and mutual respect. The design of the study employed a posttest-only control group
design with an experimental class of 20 students and a control class of 21 students.
The effect of stepwise inquiry implementation was analyzed using MANOVA. The
results reveal that the classes implementing stepwise inquiry had higher scores for
communication skills and scientific attitudes than those undertaking expository
approaches. The implementation of stepwise inquiry significantly affects the scores
of scientific communication and attitude skills based on MANOVA analysis. The
involvement of students independently in the investigation process increases their
ability to construct knowledge and build arguments, in addition to increasing their
motivation for learning. This established motivation enables the formation of
positive attitudes, such as scientific attitudes, in the students.
