Inquiry-based learning (IBL) is a student-centered approach of instruction that aims at increasing
students' active engagement and their skills of investigation, reflection, and critical thinking within real-world
expressions and practices. This literature review includes mostly those research studies in which a quasiexperimental approach was used, followed by a pretest-posttest design with random allocation of research
participants. As per the aim of this literature review, those research studies were included where elementary grade
students were selected as research participants to investigate the effects of IBL approaches on students' science
literacy and skills. One of the engaging lessons from this review shows that IBL approach science skills are described
as two sides of the same coin. Additionally, almost all reviewed studies defined IBL as students centered approach.
Moreover, the effects of IBL are also discussed in detail
