This article is aimed at teachers already experienced with activities involving small, student-collected data sets and who are now ready to begin working with large, online data sets collected by scientists and engineers. The authors discuss challenges, instructional strategies, and sources of appropriate lesson plans. With guidance, plus online…

Nowadays, with the rapid progress of Information and Communication Technologies (ICTs), the integration of ICTs in education has attracted more and more attention of educators and researchers. However, there are different situations between developed and less-developed nations both in ICT application and in ICT research. PowerPoint is a readily…

An important and interesting area in the study of triangle geometry is the related issue of extrema problems and inequalities. These problems play a significant role in the mathematics study program in high school. In tasks such as these, the difficulty level is high when one does not know in advance what the expected answer is. When one knows…

In this article, we present investigative tasks that concern loci, which integrate the use of dynamic geometry software (DGS) with mathematics for proving the obtained figures. Additional conditions were added to the loci: ellipse, parabola and circle, which result in the emergence of new loci, similar in form to the original loci. The…

Deansfield Primary School, Eltham, south-east London, is always striving to enable children to become successful learners who are confident and enthusiastic. Teachers have endeavoured to give more emphasis to science teaching and learning by bringing it up to date through research and creating a positive attitude to it among the teachers and…

This study investigated a group of six junior primary school teachers' learning as they collaboratively inquired into teaching practice they observed together. The focus of the study was on understanding how teachers collaborated around observed teaching practice to improve their pedagogy. The design involved four iterative stages of co-planning,…

The electronic and molecular structure of the acylium cation ([CH[subscript 3]CO][superscript +], 1) receives varied treatment in undergraduate textbooks and online resources. The overall structure of 1 is typically represented as an equal combination of resonance structures containing C-O triple and double bonds, the latter structure occasionally…

One goal of our Discovering the Art of Mathematics project is to empower students in the liberal arts to become confident creators of art and imaginative creators of mathematics. In this paper, we describe our experience with using string art to guide liberal arts students in exploring ideas of calculus. We provide excerpts from our inquiry-based…

This paper reports on the learning designs, teaching methods and activities most commonly employed within the disciplines in six universities in Australia. The study sought to establish if there were significant differences between the disciplines in learning designs, teaching methods and teaching activities in the current Australian context, as…

Global climate change and its effects are real and immediate. Students must gain an understanding of climate science so they can participate in public debate about how to reduce the emission of heat-trapping gases and how their communities can mitigate the effects of global warming. In this activity, students model these effects on Earth's oceans…

Why does a balloon deflate when it is left in a cold car; or why does one have to pump up his or her bike tires in the spring after leaving them in the garage all winter? To answer these questions, students must understand the relationships among temperature, pressure, and volume of a gas. The purpose of the Predict, Share, Observe, and Explain…

Objects of material culture are not always those items most commonly explored in the art classroom, and are, instead, the frequently overlooked things in people's everyday world. They are the items people collect in their homes, carry with them in backpacks, purses, and pockets, and stow on shelves in the back of closets--often the things they…

Exploration of making and changing sounds is part of the first-grade performance expectation 1-PS4-1, "Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate" (NGSS Lead States 2013, p. 10; see Internet Resource). Early learning experiences build toward…

The study aimed to step into two-person (teacher-student) educational neuroscience. We describe a physiological marker of cortical hemodynamic correlates involved in teacher-student interactions during performance of a classical teaching model, the Socratic dialog. We recorded prefrontal brain activity during dialog execution simultaneously in…

Most high school and introductory college physics classes study simple harmonic motion and various wave phenomena. With the majority of states adopting the Next Generation Science Standards and pushing students to explore the scientific process for themselves, there is a growing demand for hands-on inquiry activities that involve and develop more…
