Centrifugation is a major unit operation in chemical and biotechnology industries. Here we present a simple, hands-on laboratory experiment to teach the basic principles of centrifugation and to explore the shear effects of centrifugation using bacterial cells as model particles. This experiment provides training in the use of a bench-top…

Important science phenomena--such as atomic structure, evolution, and climate change--are often hard to observe directly. That's why an important scientific practice is to use scientific models to represent one's current understanding of a system. Using models has been included as an essential science and engineering practice in the "Next…

According to Harlen (2010) the ultimate goal of science education is for children to have an understanding of relationships, moving beyond science as a series of facts or small ideas towards seeing the bigger picture. Working with a group of 10- and 11-year-olds from a year 6 class, teacher Simon Williams provided a series of challenges using the…

Increasing student achievement is a fundamental concern for many school districts and teachers. Providing students with engaging, blended STEM educational experiences may help them understand how scientists and engineers solve problems. The purpose of this article is to share teaching strategies and student activities that will not only increase…

What is it really like to plunge into the world of science learning and teaching? Find out in this unique book. "Dive In!" grew out of a teacher-scientist project at the University of New Hampshire that promoted active learning and using science practices in the classroom. That experience yielded this book's reason for being: to provide…

The aim of this research is to discover what science teachers' opinions about outdoor education learning environments are. Outdoor education learning environments contribute to problem-solving, critical and creative thinking skills of students. For this reason, outdoor education learning environments are very important for students to learn by…

The aim of this research is to develop a guide material prepared according to Purdue Model for the 'The Let's Solve the Puzzle of Our Body' unit in the 5th grade science class at secondary school and to research the effects of this guide material on students' creative thinking. For this purpose, the research was carried out by using the quasi…

The research aims to find out the effect of project-based science education programme conducted with an active learning on scientific process skills and conceptions of 6-year-old children about nature of science. Quasi-experimental research design including experimental and control groups with pre-test and post-test was implemented. Mixed-method…

Manipulative skills and abilities include skills in the handling and manipulation of materials and apparatus in the context of scientific investigation. Science teachers appeared to be struggling with the mode of assessment in making authentic evaluation of manipulative skills in laboratories. One of the contributing factors is due to the lack of…

Employers of chemistry graduates are seeking a range of transferable skills from prospective employees, and academics are increasingly seeking to build employability skill development opportunities into the undergraduate curriculum. However, research suggests that undergraduates do not recognise or value such skill development without prompting.…

St. Olaf College recently restructured its Summer Bridge Program (SBP) course for incoming low-income (LI) and first-generation (FG) college students from a non-major biology course, "Issues in Biology," to an interdisciplinary "Explorations in Science" course. Two significant changes were made with the intention of giving…

This paper describes pedagogical efforts implemented to promote significant learning in a computational chemistry course. The taxonomy of significant learning advanced by Fink (2013) is used as a framework to discuss the results. Fink identifies six categories of learning: foundational, application, integration, human dimension, caring, and…

This practical resource emphasizes the special contribution that visual art, drama, music, and dance can make to student literacy and understanding of content-area reading assignments. Focusing on those areas where students tend to struggle, this book helps K-5 teachers provide an age-appropriate curriculum that is accessible to an increasingly…

To help teachers implement new, research-based approaches for leveraging technology to improve science, technology, engineering and mathematics (STEM) learning, a systematic review of the research literature on the impact of integrating innovative digital technology in STEM and computer science curricula and classrooms was conducted. For purposes…

There is a critical need for more effective comprehensive programs to increase the number of underrepresented minority students pursuing scientific careers. Science education often is fragmented, delivered with single-focused approaches - traditional classroom lectures, or hands-on-activities, or conducting research. The current paper examines a…
