A play-based approach to STEAM (science, technology, engineering, arts, and mathematics) that centers joy and imagination is fundamental to teaching young students about environmental civic engagement. In turn, diverse young learners of underrepresented backgrounds also need bilingual and bicultural mentors and role models to demonstrate that the…

Despite chemistry's recognized importance to multiscale industrial and environmental processes, first-year undergraduate chemistry is often regarded as comprising a collection of unconnected topics with little relevance to everyday life. Implementing systems thinking into the chemistry curriculum can help to contextualize chemistry learning and…

In today's increasingly multilingual classrooms, leveraging students' diverse linguistic resources is essential for fostering equity, inclusion and deeper learning. This action research explored the impact of translanguaging on student engagement, joy, and identity in a middle school science classroom. Translanguaging, which is leveraging…

Pre-service teachers encounter many different mentor teachers during the teaching practicum process. While some teachers give sufficient coverage to early childhood science education, some do not. This research aimed to explain effective mentoring attributes and practices of the mentors which preferred by pre-service preschool teachers during…

Systemic oppression includes inequitable education that historically does not fully prepare students for comprehensive participation in society. The tools of science education, however, uniquely enable students to explore social inequities as well as the natural world. Thus, a role of education can be to embed social justice in science curricula.…

The central pedagogical principle on which the "Next Generation Science Standards" (NGSS) are built is that of three-dimensional learning. This principle posits that it is through meaningful integration of the disciplinary core ideas (DCIs), science and engineering practices (SEPs), and crosscutting concepts (CCCs) that students will…

The Leadership/Teamwork Self-Efficacy Scale has been shown to be an effective tool for measuring interpersonal competence beliefs in science, technology, engineering, and mathematics academic settings. However, little is known about its psychometric properties. The present research explored the measure's longitudinal factor structure in the…

The CRISPR/Cas9 system opens new horizons (M. Adli, Nat Commun, 2018) regarding genetic modifications of living organisms but also as an in vitro tool in laboratory protocols. Therefore, it boosts possibilities in research and future medical treatments. As the controversial claim of genomically edited babies by He Jiankui (Cyranoski D., Nature,…

Why do we need to pour less water in an egg steamer to prepare more eggs to the same degree of 'doneness'? We discuss the physical processes at work in the electric egg steamer and resolve this seeming paradox. We demonstrate that the main heat transfer mechanism from steam to egg is due to latent heat through condensation. This not only explains…

This is an easy and inexpensive laboratory experiment in which undergraduate students at the Bachelor's degree level in Chemistry can measure formation constants of complexes [Ni(en)[subscript n](OH[subscript 2])[subscript 6-2n]][superscript 2]+ (n = 1, 2 or 3; en = ethylenediamine) through an acid-base titration. The background information…

Primary school topics involving abstract concepts are challenging to teach. Electric circuits can be simply constructed but complex to explain. New approaches in teaching students for understanding are needed to advance practice in primary science. This paper combines the strengths of multimodality research perspectives with variation theory to…

Elemental analysis is performed in a variety of ways in food and environmental sciences; thus, we have designed an activity in which students gain experience with research-level lab techniques in a real-world context through the quantification of key elements in breakfast cereals using microwave plasma optical emission spectroscopy (MP-OES). The…

Chemical solubility and equilibria are paramount for understanding everyday systems. Recent events have led to more interest by the general public in chemical equilibria that occur in drinking water systems. This presents a great opportunity to increase student interest and engagement in the more complicated aspects of chemical equilibria. Shiny…

A multistep synthesis of a novel arylidene 3­(2"H")-furanone has been designed and optimized for the second-year organic laboratory. The three-step sequence consists of a nucleophilic substitution, intramolecular cyclization, and acid-catalyzed aldol condensation, and can be carried out within two 3 h laboratory periods. The final…

Introductory anatomy and physiology courses are either taught as discipline-specific courses (human anatomy and human physiology) or integrated sequences [combined human anatomy and physiology (A&P I and A&P II)]. This variation suggests there is no agreed upon pedagogical standard for teaching introductory anatomy and physiology. We…
