Thomas Graham discovered the law that bears his name while studying gas diffusion into air and other gases. He also found that the same relationship held with gas effusion, the movement of gases through a pinhole into a vacuum. Modern understanding of diffusion and effusion is based on kinetic-molecular theory, and it is generally accepted that…

Mathematics is one of the most emphasized subjects and has grown immensely to provide a strong base for programs in science, engineering and technology. Training students in this field will give them the opportunity to improve their high order thinking skills (HOTS). But the students' HOTS level is at low stage due to the learning approaches…

Using three interdependent constructs: social, cognitive, and teaching presence, the Community of Inquiry framework is a theoretical process model of online learning. Specifically, teaching presence contains three sub-elements: (1) facilitation of discourse; (2) direct instruction; and (3) instructional design and organization--that work together…

Over the past several decades, empirical support for inquiry-based forms of science teaching has accumulated. Critical voices, however, also exist, claiming that minimally guided teaching approaches might be less effective than guided forms; they might even be harmful, particularly for novice students, due to the production of cognitive overload.…

This study explores emergent reflective structuration as a new form of shared regulation. The purpose is to support students in taking on high-level epistemic agency as they co-configure dynamic inquiry pathways that unfold over long periods of time. With the teacher's support, students not only regulate their inquiry and collaboration following…

This study sought to examine whether teachers' and educational administrators' conceptions of inquiry promote or constrain inquiry-based science teaching in junior high schools. The study also explored any connections between participants' conceptions of scientific inquiry, inquiry teaching, and inquiry learning. Multiple-case study involving…

The teaching strategies of Francis and Edith Schaeffer helped young adults construct meaning in their lives. During several seasons of tumultuous social unrest, the Schaeffers consistently gave shelter to many confused, searching, and hurting adults. Their educational motto was "honest answers to honest questions." For nearly thirty…

This paper investigates how the teaching and learning about "wicked" environmental problems may be fostered through an educational approach premised on futuring -- the active imagination of the future. The growing academic interest in possible and desirable futures provides a promising starting point for restructuring education as…

We investigated the effects of just-in-time guidance at various stages of inquiry learning by novice learners. Thirteen participants, randomly assigned to an intervention (n = 8) or control (n = 5) group, were observed as they learned about DC electric circuits using a web-based simulation. Just-in-time instructional prompts to observe, predict,…

Many research results show that students often highlight "mixed-type" reasoning when tackling problematic situations and problems. This reasoning is based on the simultaneous use of common-sense and mere descriptions of facts, perceived as sufficient to build an "explanation" of observed or proposed situations and problems.…

This study aims to specify the effect of inquiry-based collaborative learning and inquiry-based online collaborative learning methods on students' success and permanent learning. In this quantitative study, a pre-test post-test non-equalized control group model of quasi-experimental design has been used. The study's sample comprises 64 students,…

In this study, I sought to understand the disciplinary nature of an expert third-grade teacher's practice as she apprenticed students into ways of reading, analyzing, and employing historical evidence. Using a case study methodology, I draw on classroom observation data, teacher interviews, and classroom artifacts to identify instances where the…

In this instrumental case study, we examined the ways in which one mathematician's instruction unfolded during his participation in a faculty collaboration geared towards reforming instruction. In the study, we offer the case as both the participant's collaborative experience in an online faculty collaboration and his implementation of an inquiry…

With the proliferation of information on how to use data to inform instruction for more than two decades, district leaders, principals, and other stakeholders assume teachers know how to use the cycle of inquiry process to improve student achievement. This case study is an examination of the practice of data use in seven schools in one urban…

Game-based learning supported by mobile intelligence technology has promoted the renewal of teaching and learning models. Herein, a model of Question-Observation-Doing-Explanation (QODE) based on smart phones was constructed and applied to science learning during school disruption in COVID-19 pandemic. In this study, from the theoretical…
