Red onion, "Allium cepa," juice can dye a cloth sample green upon the addition of alum, aluminum potassium sulfate, and this sample can turn red when subjected to an acidic solution. When the red-colored sample is washed with a neutral or alkaline aqueous solution, its color turns green again. These experiments illustrate color changes…

In this work we present the application of design based research (DBR) methodology to conduct a systematic iterative study of the design and implementation of a teaching-learning sequence (TLS) on emf (electromotive force). This work is the final part of a broader study that started with the analysis of students' difficulties with emf in the…

Project-based learning (PJBL) is student-centered and teamwork educational activity that prepares students for the challenge of real-world problems. This kind of instructional method is highly recommended by the Accreditation Board for Engineering and Technology (ABET).This paper describes an authentic project that focuses on the preparation of…

Applying physical principles is important for designs of various products with tailored performances. However, one of the long-standing issues of the students' design projects (or school's interdisciplinary projects) is the post-hoc imposition of the knowledge learned in their content subjects. This post-hoc imposition significantly diminishes the…

This dissertation describes a practitioner's design-based development of a prototype chatbot to guide students in learning biological concepts of genetic mutations and protein synthesis. This chatbot's architecture provides learning activities, feedback, and support throughout a series of short, connected lessons. The chatbot is designed to…

What better way to engage fifth-grade students in science and engineering practices than to use paper airplanes to encourage them to question, explore, create, and test designs! This multi-day unit draws from a fourth-grade curriculum (Pearson 2012) aligned with the "Next Generation Science Standards" (NGSS Lead States 2013) used in…

This communication provides an initial report of modifications of a pedagogically complex, large enrollment (>200 student), studio-based course in response to the COVID-19 pandemic. Compared to face-to-face delivery, course activities were identified as new, modified significantly, or relatively similar. Students were asked to rank eight…

This study aimed to make a teaching model out of the instructional flows of the teachers teaching engineering chemistry course. Specifically, the study aimed to identify the teaching styles the teachers used in the actually delivery of the chemistry lessons. Thus, this is a descriptive study on the teaching style employed and learning styles…

Integrated science, technology, engineering, and mathematics (STEM) education is becoming increasingly common in K-12 classrooms, and small group activities are ubiquitous to STEM instruction. This article includes both theoretical and practical descriptions of a microethnographic approach to critical multimodal discourse analysis that we used to…

This 5E (Engage, Explore, Explain, Elaborate, and Evaluate) learning cycle integrating science and mathematics challenges and engages second-grade students in designing sail cars to solve an engineering problem. Students create and use line plots to organize their data to evaluate the strengths and weakness of their design solutions. Three…

STEM education is becoming more common in schools and provides a range of exciting real-world contexts in which students can engage. However, a gap in most approaches to STEM remains the collection and use of data that can be used concurrently to develop statistical literacy and science literacy. This paper describes a STEM activity carried out…

The connections the "Next Generation Science Standards" ("NGSS") creates between science content and practices to literacy and mathematics are especially beneficial at the elementary level. In this article, the authors present a series of lessons a second-grade teacher taught within a thematic unit that integrated standards…

Self-efficacy represents an individual's belief that he or she can perform a particular task in a given domain. It is a strong predictor for performance and persistence in STEM education. Research shows that there is a large and persistent gender gap in student self-efficacy in STEM academic disciplines. In some cases, active teaching strategies…

Although environmental radioactivity is all around us, the collective public imagination often associates a negative feeling to this natural phenomenon. To increase the familiarity with this phenomenon we have designed, implemented, and tested an interdisciplinary educational activity for pre-collegiate students in which nuclear engineering and…

Lab activities have been innovated and progressed to fulfill the purpose that students need to experience physics concepts through hands-on and minds-on interactions. However, student-centered and conceptual activities in physics labs are challenged with time and material constraints that degrades the merits of the learning environment. This study…
