This study examines the difference in effectiveness between two scientific inquiry programs—one with an emphasis on scientific reasoning and one without a scientific reasoning component—on students-scientific concepts, scientific concept-dependent reasoning, and scientific inquiry. A mixed-method approach was used in which 115 grade 5 students were administered the scientific concept test, scientific concept-dependent reasoning test, and scientific inquiry test before, 1?week after, and 8?weeks after instruction. In addition, students-scientific inquiry worksheets in the classroom were collected and evaluated. Results indicated that the experimental group outperformed the control group, regardless of scientific concept test, scientific concept-dependent reasoning test, and scientific inquiry test. Moreover, the classroom inquiry worksheets results demonstrated that the experimental group generated a significantly greater number of testable hypotheses, correct hypotheses, and correct evidence-based scientific explanations and a higher level of scientific reasoning than did the control group.
