Silver and its compounds have been widely used in experimental teaching, industrial production, and other fields. In these processes, a large amount of wastewater containing silver is usually produced, which might contribute to environmental pollution. Therefore, recycling silver from wastewater not only has good economic value but also meets the…

Colleges throughout the United States typically expect their students to take at least one course in the sciences to fulfill liberal studies curriculum requirements. For nonscience majors, the choice of science class can include introductory chemistry, introductory biology, and astronomy, among others. Based upon interactions both in and out of…

It is critical to develop students' science communication skills as they progress through their education. One way this goal can be accomplished is by integrating Flip into educational programs. Through Flip educators create prompts that students respond to in video form, which leads to deeper discussion on various topics. This brief will share an…

Physics teachers around the world are trying to create classroom environments that would allow life science students to be more intrinsically motivated in their work. These efforts include, among others, matching classroom activities to students' interests as well as structurally variable activities to match different student abilities. While…

Teaching biochemistry well is not an easy job for teachers and so is learning biochemistry well for students. Just as many students often complain, they virtually always fail in either physiology or biochemistry. I have been teaching biochemistry at Nanjing University for over 25 years and am very successful in my biochemistry-teaching career. The…

Imagine two groups of students in your physics class or lab. In Group A, the students each take on a different task but invest an equal amount of time, energy, and effort in what they do. For example, one student might be the note-taker, while another operates the calculator, computer, or experimental apparatus, and a third keeps everyone on track…

Hydrogel is an interesting topic in polymer chemistry, which is closely related to daily life and advanced technology. In this paper, we report an activity to deliver hydrogel chemistry into middle school classrooms by undergraduates as a bridge between professors and students. During the activity, undergraduates act as a bridge to receive…

Chemistry laboratory experiments are invaluable to students' acquisition of necessary synthetic, analytical, and instrumental skills during their undergraduate studies. However, the COVID-19 pandemic rendered face-to-face (f2f), in-person teaching laboratory experiences impossible from late 2019-2020 and forced educators to rapidly develop new…

Multilevel bifactor item response theory (IRT) models are commonly used to account for features of the data that are related to the sampling and measurement processes used to gather those data. These models conventionally make assumptions about the portions of the data structure that represent these features. Unfortunately, when data violate these…

The SunSpaceArt (SSA) project, led by the author, a solar scientist at the University of Cambridge, comprises a diverse team of scientists and visual artists who run STEAM (STEM + Arts) workshops in schools, space camps and at other venues (museums, science centres and so on). The project focuses mainly on 7- to 12-year-olds, which is a key age…

In this article, the author describes the impact of the Great Science Share for Schools (GSSfS). This annual campaign has already engaged over 100,000 pupils since its start in 2016. With 2019 seeing a record-breaking 63,614 pupils registered across 483 events in 11 countries, the forecast for 2020 is looking positive. Set up by the Science &…

My childhood experience in school was fragmented from my out of school experience where I lived in rural China. School subject matters were reduced to bits and pieces. I excelled in this artificial symbolic world. Progressing from preschool to graduate school, I trained to teach in that world, and gained the opportunity to study at Harvard. My…

This column shares reflections or thoughtful opinions on issues of broad interest to the community. This issue discusses Professional Science Master's degree programs.

Our purpose in this paper is to shed light on the intricacies of designing and enacting curricular innovations aiming to enhance students' interest in science and their understandings of STEM careers. We present the design and describe the implementation of a set of STEM career-oriented curriculum materials referred to as career-based scenarios. A…

Kathleen Allen's reverence for the stories of women naturalists spanning from the seventeenth through the twentieth centuries, and their parallel scientific interest in the documentation of life cycles through art and narratives, gives support to the child in history and nature that is so central to Montessori formal research and discipline. The…
