The "Forty Electronic Challenges" is a "discovery learning" and socio-constructivist science activity that has become rather popular in Canada. The article recalls its emergence and development. It discusses its theoretical underpinnings and how it fits into the existing literature. It then gives educators all the guidelines…

This study explores teachers' use of questioning during collaborative science exploratory activities. We classified a total of 755 questions across 14 preschool science lessons implemented by four teachers by type (open- or closed-ended) and content (science or non-science related) while also recording the intended recipient. Results revealed…

The Periodic Table of Elements is a valuable resource for chemists and all kinds of STEM professionals. However, it can be initially overwhelming and intimidating to some students. This hands-on lesson introduces abstract concepts in the periodic table through a tangible experience with simple toys and household objects. Students collaborate and…

This paper will describe a guided inquiry activity for teaching ligand field theory. Previous research suggests the guided inquiry approach is highly effective for student learning. This activity familiarizes students with the key concepts of molecular orbital theory applied to coordination complexes. Students will learn to identify factors that…

A multipart laboratory activity introducing microbeads was created to meet engineering and engineering design practices consistent with new Next Generation Science Standards (NGSS). Microbeads are a current topic of concern as they have been found to cause adverse impacts in both marine and freshwater systems resulting in multiple states proposing…

Presents four stoichiometric problems and their solutions that use spot metal prices quoted from the newspaper to integrate economics and chemistry. (MDH)

The purpose of this guide is to provide teachers with information that will help them better understand how to teach science. In addition, this resource is intended to be a tool in assisting teachers in developing their science curricula and in planning their instruction. The instructional approach presented reflects the philosophy that students…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
