Student-centered teaching has become increasingly common in higher education as researchers have demonstrated its efficacy in recent decades. Herein, we hope to establish an efficient problem-based learning (PBL) method, which can help upper-division students learn organic chemistry content by combining teaching materials, experimental literature,…

An experiment in teaching students to use the literature to devise and defend a plan for novel research is presented as part of a graduate-level course in heterocyclic chemistry. Students in three successive iterations of the course completed an assignment during which they were assigned novel heterocyclic cores that were selected by varying or…

The eight scientific practices in the Next Generation Science Standards (NGSS) are significant theoretical constructs that reflect the nature of science; they are intended to guide science teaching and learning. Yet, operationalization of these practices in terms of student learning remains limited, and a measurement tool for the eight practices…

Integrating mathematics content into science usually plays a supporting role, where students use their existing mathematical knowledge for solving science tasks without exhibiting any new mathematical meanings during the process. To help students explore the reciprocal relationship between math and science, we designed an instructional module that…

It has been argued that students' understanding of science ideas and concepts is based on their engagement in science and engineering practices. However, research studying science and engineering practices engaging in the content of school science textbooks is particularly limited. The aim of the present study is to develop a framework and…

The aim of the study is to adapt Preschool Children's Science Motivation Scale (PCSMS) developed by Oppermann et al. into Turkish and conduct the validity and reliability analyses. This scale is considered important in terms of evaluating the science motivation of preschool children through the science concepts they are familiar with, based on…

An instructional approach is presented for teaching the mole concept to high school introductory-level chemistry classes. Extensions to the strategy are presented for more advanced classes. The strength of the approach is based upon discovery. Students discover the Avogadro number and the mole concept. The discovery is based upon calculations that…

At the core of an effective model-based inquiry (MBI) unit is a scientifically rich, complex phenomenon that serves as the reason for engagement and drives student sensemaking and investigations throughout the unit. Engaging in iterative attempts to explain phenomena over the course of an MBI unit allows the opportunity for students to construct…

This study aims to develop and validate a new instrument for measuring chemistry teachers' perceptions of Pedagogical Content Knowledge for teaching Chemistry Core Competencies (PCK_CCC) in the context of new Chinese chemistry curriculum reform. The five constructs and the initial 17 items in the new instrument were contextualized by the PCK…

The current COVID-19 pandemic shows how little many people know about viruses. Yet apart from COVID-19, the world has observed epidemic spread of another SARS virus, of the Ebola virus, and of the Zika virus during the last two decades. The human immunodeficiency virus (HIV) is still one of the most dangerous viruses worldwide. Some types of the…

A study on the misconceptions developed or held by teachers related to the two terms valence and valency was undertaken. A total of 48 teachers (26 males and 22 females) teaching the chemistry component of science subject to 14-16-year-old students, in 48 schools affiliated to one district, were randomly selected for the study by taking one…

Although one of key ideas behind the introduction of STEM (or STEAM) as a unifying concept, is to emphasize the interdisciplinary character of many real world problems, there is a non-trivial educational challenge in exceeding existing subject boundaries and implementing multidisciplinary activities into the classroom. The present case study…

Video motion analysis allows tracing trajectories of objects in motion and is an established method in physics education. Tablet computers, with their integrated cameras, offer the opportunity to both record and analyze dynamic motions during experiments on a single device. This enables students to work without transitioning the data between…

Quantum computers are at the forefront of computing; however, few people understand how they work and their capabilities. We present two versions of an interactive activity designed for high school students (ages 13 to 18) that introduce a core quantum concept--"entanglement." The first version illustrates a simple connection between two…

At Race Leys Junior School in Warwickshire, creative and unique experiences are at the forefront of the minds of the teachers. As a team, the teachers are always seeking new and innovative ideas to enrich their curriculum. Over the last year, through the COVID-19 pandemic, they have become more adventurous with their thinking and lesson delivery.…
