Limited empirical research has investigated the impact of interdisciplinary STEM approaches on students' learning with a particular dearth in the area of assessment. A lack of alignment between interdisciplinary approaches in STEM teaching and its assessment strategies is notable. In this study, we adopt an inquiry approach to the ways in which…

A key process in the discipline of science is argumentation, which has recently been receiving more attention in K-12 classrooms. The purpose of this multiple case study was to concurrently examine self-regulated learning processes (SRL) and learning outcomes of three teachers in a professional development (PD) on argumentation in science to…

The purpose of this study was to reveal the experiences of science teachers during the pandemic and their recommendations about the post-pandemic process. In the study, the "first period" referred to the period when the pandemic first appeared (the period between March-June 2020) and the "second period" referred to the…

After the passage of the U.S. National Quantum Initiative Act in December 2018, the National Science Foundation (NSF) and the Office of Science and Technology Policy (OSTP) recently assembled an interagency working group and conducted a workshop titled "Key Concepts for Future Quantum Information Science Learners" that focused on…

Efforts to improve student learning in K-12 education in the US are not new; however, educational research has traditionally focused on individual components of schools (e.g., teacher professional development, leadership, social relationships, programs, curricula) targeting teachers to improve student learning. While these innovations provide hope…

One of the goals of science education is to help students make sense of the world around them. To that end, it is critical that students understand the central ideas in each discipline like, in chemistry, energy and interactions. These ideas are of particular importance because they are directly related to one another and are relevant across other…

Next Generation Science Standards (NGSS) science and engineering practices (SEPs) involve commands of the English language in writing, speaking, reading, and listening. Language tasks embedded in NGSS SEPs require English learners (ELs) to develop science skills and understanding and language proficiency simultaneously. Sense of self-efficacy…

Undergraduate genetics courses have historically focused on simple genetic models, rather than taking a more multifactorial approach where students explore how traits are influenced by a combination of genes, the environment, and gene-by-environment interactions. While a focus on simple genetic models can provide straightforward examples to…

Scholars continue to propose that students develop scientific literacy and 21st century competencies through student-centered reform-based science instruction with the teacher as the main facilitator of learning (Maeng et al., 2018). The National Science Teaching Association (2018) called for high-quality science instruction that builds on…

The Lead Teacher Program (LTP) is organized by Beyond Benign, an institution that promotes green chemistry principles and sustainability in education. LTP trains K-12 teachers to run workshops in their own communities across the US and Canada. This research project aimed to study the culture among K-12 science teachers in LTP and how they share…

Under the threat of the COVID-19 pandemic, an interdisciplinary project about the brewing and analysis of traditional Chinese rice wine was performed at home by junior students of the chemistry major at Huanggang Normal University under the remote guidance of teachers during the spring lockdown semester of 2020. Students were exposed to the…

Accidents occur in laboratories due to a lack of proper knowledge regarding laboratory safety measures, perilous attitudes, and unacceptable laboratory practices. This study assessed the chemistry laboratory safety knowledge, attitude, and practice (KAP) of teachers and laboratory technicians in secondary schools of South Wollo, Ethiopia. The…

We introduced a microfluidic paper-based analytical device ([mu]PAD) to undergraduates majoring in nutrition education using a modified acid-base titration on paper microzones. After designing experiments for sample analysis using micro acid-base titration, students fabricated the devices and implement the experiment as designed. Then they…

In order to measure the mass of an object in the absence of gravity, one useful tool for many decades has been the inertial balance. One of the simplest forms of inertial balance is made by two mass holders or pans joined together with two stiff metal plates, which act as springs.

In a recent letter to this journal, Mungan noted that translational energy can be converted into gravitational potential energy when an object is projected vertically, but rotational energy is not usually converted in this manner. As an exception, he gave an example where "a ball initially rolling without slipping will travel higher up a…
