Hands-on learning is a highly effective teaching method for topics in STEM disciplines. Unfortunately, environmental science teachers sometimes lack the tools to engage their students in hands-on experimentation in real-world research outside of the classroom. Partnerships between science professionals and teachers can help address this disparity,…

This article describes the principles, applications and performances of methods to measure gas-phase air pollutants that either utilise passive or active sampling with subsequent laboratory analysis or involve automated "in situ" sampling and analysis. It focuses on air pollutants that have adverse impacts on human health (nitrogen…

Inquiry-driven lab exercises require students to think carefully about a question, carry out an investigation of that question, and critically analyze the results of their investigation. Here, we describe the implementation and assessment of an inquiry-based laboratory exercise in which students obtain and analyze novel data that contribute to our…

This paper presents part of the findings from a comparative study on existing and proposed science curricula of grades IX-X in Bangladesh. It aims to explore relevant research to find out what ideas about science are recommended to include in school science curriculum, and then to compare the existing and proposed curricula in terms of ideas about…

It is hard and getting harder to strike a satisfying balance in teaching. Time dedicated to student-generated models or ideas is often sacrificed in an effort to "get through the syllabus." I describe a series of RNA interference (RNAi) experiments for undergraduate students that simultaneously explores fundamental concepts in gene regulation,…

How do we see young children's thinking in science? Is it, as much previous research has led us to believe, that their ideas can be neatly boxed like "brown paper packages tied up with strings"--as the song from "The Sound of Music" goes? Or are their ideas like "wild geese that fly with the moon on their wings" ("Sound of Music"): fluid, complex,…
