The chemistry laboratory is an impactful platform for introducing inquiry and developing science practice skills. We designed a short lab course to introduce incremental levels of inquiry, also to interconnect and integrate different domains of chemistry. Indigo dye was the central theme of this short course wherein students synthesized indigo,…

This study investigated the causes of modifications on "Tradescantia zebrina" leaves due to environmental effects by inquiry-based and long-term observations. These observations started with restricted face-to-face education at school during the COVID-19 and continued under the teacher's guidance in distance education. All the study…

In this article, we argue that physical rooms cannot be replaced by virtual space without literally losing the student's body and that experimenting with rooms and active learning is imperative for improving and advancing students' learning. Our case study offers insight into a 'soft room experiment' without hard furniture or audio-visual…

The need for shifting the expository laboratory instruction style to inquiry-based approaches is widely acknowledged. Problem-based learning (PBL), one of the inquiry-based approaches, advocates students' self-directed learning. The literature indicates that scaffolding students' independent learning is necessary for a PBL environment. In our…

Although research and new technologies have introduced different ways of observing microorganisms, including scanning and electron microscopy, these methods are expensive and require equipment that is typically not found in a middle school classroom. The transmission-through-dye technique (TTD; Gregg et al., 2010), a new optical microscopy method…

In this article, we present an overview of a suite of light and spectroscopy education materials developed as part of Project LITE (Light Inquiry Through Experiments). We also present an analysis of how introductory college astronomy students using these Project LITE materials performed on the Light and Spectroscopy Concept Inventory (LSCI)…
