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…

Undergraduate organic chemistry laboratory courses act as a baseline for introductory scientific experimentation. These courses provide students with the knowledge and skills for their future careers. The traditional lab is conducted by providing a structured protocol of the experiment for the students to follow and reproduce the assigned task…

A process for generating and writing an individual research proposal with or without access to advanced experimental techniques is described herein. This process was first included in a glycoconjugate biochemistry course to increase student interaction with more areas of the field, but the process was designed to be applicable elsewhere as well.…

Active learning pedagogies offer opportunities to increase student engagement and interest in plants. The Mystery Plant Project is a hands-on, semester-long active learning pedagogy I developed for an introductory, undergraduate Plant Biology course. Students investigate various aspects of their mystery plant species using observations, and…

In recent years, with the more powerful functions of smartphones, the use of sensors integrated by mobile phones as an auxiliary tool for physical experiment teaching has become more popular. Combined with the related mobile phone apps, people easily can develop and expand the physical experiment contents of mechanics, optics, acoustic phenomena,…

It is generally agreed that making real-world connections in mathematics teaching increases students' motivation and interest and contributes to meaningful and permanent learning. In this paper we propose a simple and fast activity to find a rectangular hyperbola in real life and we show how to operate the data to retrieve a straight line. Since…

Science instruction is a critical aspect of early learning. Teachers can support young children's learning about scientific concepts through the use of the Universal Design for Learning (UDL) framework, which is a proactive approach to instructional planning that helps ensure success for all learners. This teaching techniques article offers…

This article describes a new competence-oriented teaching rationale for a science course, developed in Germany through close cooperation between teachers and researchers, that seeks to improve scientific literacy at upper-level secondary school (ages 15-17). Its aim is to help students become independent and competent experimenters by combining…

The author believes that science within a primary school is there to enable children to be interested in the world around them and to help them start to understand it, getting them interested in the very basics, and pointing out things around them that they had not considered, so that they can start asking the questions 'why' and 'how' and 'what'…

Since physics is often a service course for college students, it is important to incorporate everyday examples in the curriculum that inspire students of diverse backgrounds and interests. In this regard, baseball has been a workhorse for the physics classroom for a long time, taking the form of demonstrations and example problems. In this…

Science, Technology, Engineering, and Math (STEM) have developed broad prevalence in the American (U.S.) education system over the last decade. Academic, government, and business experts emphasize that attracting K-12-university students to STEM subject matter is crucial for expanding the innovation capacity of the U.S. and preparing citizens for…

'Reading science for pleasure' features little in school-related science education literature and scant guidance is available for teachers who wish to promote this practice among their pupils. This is the second of a pair of articles charting the development of Project 500 (Schools), a programme aiming to encourage children and young teens to read…

As a science leader in her school, the author is always looking for new and interesting ways to inspire children in the science, technology, engineering, mathematics (STEM) subjects. Attending several science conferences introduced her to new STEM programs, such as Street Science and fractals. In this article, she shares a couple of the activities…

Sports are a popular and effective way to illustrate physics principles. Baseball in particular presents a number of opportunities to motivate student interest and teach concepts. Several articles have appeared in this journal on this topic, illustrating a wide variety of areas of physics. In addition, several websites and an entire book are…

Incorporating research-based lab activities into general chemistry at a large university can be challenging, considering the high enrollments and costs typically associated with the courses. Performing sweeping curricular overhauls of the general chemistry laboratory can be difficult, and in some cases discouraged, as many would rather maintain…
