A practical exercise for developing a simple cost-effective solar ultraviolet radiation dosimeter is presented for use by middle school science students. Specifically, this exercise investigates a series of experiments utilising the historical blue print reaction, combining ammonium iron citrate and potassium hexacyanoferrate to develop an…

Immunological detection of proteins is an essential method to demonstrate to undergraduate biology students, however, is often difficult in resource and time poor student laboratory sessions. This method describes a failsafe method to rapidly and economically demonstrate this technique using biotinylated proteins or biotin itself as targets for…

Teaching is a complex activity that requires making ongoing multiple decisions and sporadic, responsive actions all while performing preplanned prescribed tasks. Evidence of certain aspects of teaching can be best assessed with a well-designed observation instrument. This instrument was designed to assess the enactment of the essential elements of…

This paper presents a series of activities and educational strategies related to the teaching of digital electronics in computer engineering. The main objective of these methodologies was to develop a final tutored coursework to be carried out by the students in small teams. This coursework was conceived as consisting of advanced problems or small…

The authors evaluated the effects of P-SELL, a science curricular and professional development intervention for fifth-grade students with a focus on English language learners (ELLs). Using a randomized controlled trial design with 33 treatment and 33 control schools across three school districts in one state, we found significant and meaningfully…

The "Biotechnology Discoveries and Applications" guidebook aims to provide teachers with an overview of the recent advances in genetics and biotechnology, allowing them to share these findings with their students. The annual guidebook introduces a wealth of modern genomic discoveries and provides teachers with tools to integrate exciting…

In this article, the author presents the science and engineering practices from the recently released "A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas" (NRC 2011). The author recognizes the changes implied by the new framework, and that a new generation of science education standards will present new…

A complete course of respiratory physiology suitable for first-year medical and graduate students has been placed on the Web for our own students and for other educational institutions. There are several reasons for doing this. The first is that the modern-day student uses a variety of options for acquiring knowledge. These include attending…

Current instructional and learning models insist that when teachers prepare lessons for their technology and engineering classes, they must begin with a sense of what students already know. In preparing lessons, many teachers use their years of classroom experience as data to inform them about students' prior knowledge and about student…

This open-ended practical series titled "Molecular Identification of Unknown Food Bacteria" which extended over a 6-week period was designed with the aims of giving students an opportunity to gain an understanding of naturally occurring food bacteria and skills in contemporary molecular methods using real food samples. The students first isolated…

Human rhinovirus (HRV) is one of the most common human respiratory pathogens and is responsible for the majority of upper respiratory illnesses. Recently, a phylogeny was constructed from all known American Type Culture Collection (ATCC) HRV sequences. From this study, three HRV classifications (HRVA, HRVB, and HRVC) were determined and techniques…

In this article, the author talks about Primary Science Committee's (PSC) joint meeting with members of the Scottish Primary Group in Edinburgh. The remit of the group is to advise on primary matters, develop primary aspects of Scottish Region's Annual Conference and run primary-focused continuing professional development (CPD) events as part of…

There are a variety of computing tools available in educational institutions. With the knowledge of standard tools and how they can be used to compliment one another, students can gain impressive skills in information presentation. This paper describes a method for science students to use in preparing data for analysis and dissemination and…

This book was written to make it easier for classroom teachers to teach students the skills they need to successfully conduct, analyze, and report an experiment and to carry out independent research; it also presents strategies for holding successful science competitions. Part 1 contains field-tested teaching strategies for developing student…

Predicting weather conditions is a topic of interest for students who want to make plans for outside activities. This paper discusses the development of an inexpensive computer-interfaced classroom weather station using an Apple IIe computer that provides the viewer with up to the minute digital readings of inside and outside temperature,…
