Fostering ecosystem understanding: The synergistic impact of inquiry-based instruction and information literacy

Abstract

In the field of environmental education, it is crucial to obtain a profound understanding of students' learning about ecosystem concepts, particularly with regard to the intricate processes of material cycling. Material cycling involves the movement and transformation of elements and compounds within ecosystems and serves as a cornerstone for effective instructional techniques aimed at improving learning outcomes. This study examines the synergistic potential of merging inquiry-based instruction with information literacy within the context of the “mini ecosystem” theme to increase seventh-grade students' comprehension of ecosystem concepts, material cycling, modeling design, and visual literacy. Utilizing a quasiexperimental design, the student cohort was divided into an experimental group that was exposed to inquiry-based instruction and information literacy and a control group that utilized integrated audiovisual media. Assessment tools included standardized tests, open-ended inquiries, design drawings, and evaluations of visual literacy.

This study sheds light on students' comprehension of concepts related to ecosystems and material cycling and highlights the effectiveness of integrating inquiry-based instruction and information literacy. Notably, the experimental group surpassed the control group in several aspects, including understanding and higher-order thinking of ecosystem concepts, overall model design with material selection, and overall visual literacy, including aesthetic techniques and creative imagination. However, no significant differences were found in conceptual design or material cycling of model design or in theme composition in visual literacy. In both groups, students with higher pretest scores did not exhibit improvement in the understanding of ecosystem concepts. Despite the identified limitations, the results underscore the potential benefits of each individual component (i.e., inquiry-based instruction and information literacy) as well as their combined synergistic effect in bolstering students' grasp of ecosystem concepts. The study concludes by discussing its limitations and providing suggestions for future research.
