The present study examines how the overall cognitive achievements in science of the younger children in a class where the students work in small multi-age groups are influenced by the number of older children in the groups. The context of the study was early-years education. The study has two parts: The first part involved classes attended by…

We present a practical activity focusing on two main goals: to give learners the opportunity to experience how the scientific method works and to increase their knowledge about enzymes in everyday situations. The exercise consists of determining the amylase activity of commercial detergents. The methodology is based on a qualitative assay using a…

Spatial thinking is often challenging for introductory geology students. A pilot study using the Augmented Reality sandbox (AR sandbox) suggests it can be a powerful tool for bridging the gap between two-dimensional (2D) representations and real landscapes, as well as enhancing the spatial thinking and modeling abilities of students. The AR…

Using data from the 2006 Program for International Student Assessment (PISA), we explored nine aspects of science engagement (science self-efficacy, science self-concept, enjoyment of science, general interest in learning science, instrumental motivation for science, future-oriented science motivation, general value of science, personal value of…

Using three constructs taken from Latour's 2005 book, "Reassembling the Social," we consider our work in 2 contexts that were part of a project to support science teachers working with English learners: an 8th-grade physical science class in a summer science enrichment academy, and a 6th-grade Earth science class in a public middle…

An after-school enrichment activity offered to sixth-grade students gave a group of 10 students an opportunity to explore the effects of the California drought in their community using an engaging scientific device: the UAV (unmanned aerial vehicle). Although this activity was specifically designed for a small after-school enrichment group, it…

This article provides readers with details concerning the implementation of four active learning techniques used to help undergraduate students critically discuss primary literature. On the basis of undergraduate and graduate student perceptions and experiences, the authors suggest techniques to enhance the quality of dual-listed courses and…

Understanding young people's educational choice is of interest in order to recruit sufficient numbers of young people to careers in science, technology, engineering and mathematics (STEM). In this article, questionnaire data (closed and open-ended questions) from 5,007 Norwegian first-year students in all STEM higher-education disciplines are…

This design-based research study considers the learner-generated design and refinement of a school garden. We report one enactment of the Connected Gardening project in order to illuminate and understand how a fourth-grade class organizes and refines its garden plot using observations of the physical environment and evaluations of data from a…

Both, virtual and printed 3D crystal models can help students and teachers deal with chemical education topics such as symmetry and point groups. In the present paper, two freely downloadable tools (interactive PDF files and a mobile app) are presented as examples of the application of 3D design to study point-symmetry. The use of 3D printing to…

The main purposes of this study were to identify Taiwanese university students' physics learning profiles in terms of their critical conceptions of learning physics and to compare their physics learning self-efficacy with the different learning profiles. A total of 250 Taiwanese undergraduates who were majoring in physics participated in this…

Scientific modeling has been advocated as one of the core practices in recent science education policy initiatives. In modeling-based instruction (MBI), students use, construct, and revise models to gain scientific knowledge and inquiry skills. Oftentimes, the benefits of MBI have been documented using assessments targeting students' conceptual…

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…

Using current research and real-life scenarios to motivate students to understand chemistry principles is a key strategy in learning and teaching. An illustration of psychoactive drugs referred to as "legal highs" used in the U.K. and Europe is presented to highlight key chemistry principles and relate the importance of chemistry…

Science capabilities are a set of ideas for teachers to think with about science education. There are five: gathering and interpreting data, using evidence, critiquing evidence, interpreting representations of science, and engaging with science. This paper explores what student progress in developing capabilities might look like. It draws on…
