Nowadays, students have digital skills that are much larger than any other student in the past. Traditional experiments in a real laboratory are still fundamental, however an increasing number of computers can be used to simulate experiments close to the experimental environment. This can be seen as a great advantage for science learning, as…

Background: Students' well preparedness for laboratory sessions is of importance for a number of reasons including them being able to engage in and learn from the session and in acquiring the necessary laboratory skills needed for the scientific community and for possible further work in industry. To enhance the preparedness of the students an…

The Next Generation Science Standards (NGSS) and other national frameworks are calling for much more sophisticated approaches to STEM education, centered around the integration of complex experimentation (including real labs, not just simulations), data collection and analysis, modeling, and data-driven argumentation, i.e., students can behave…

In this study, we present an activity in which the free-body diagram of a real stationary object on an inclined plane can be examined interactively. We use an Apple Watch and a few other materials that can be accessed easily. Instead of an Apple Watch, a mobile phone or a tablet could also be used. This activity may be employed to introduce the…

We developed an educational path based on nitinol, a shape memory alloy which conveniently exemplifies the smart material concept, i.e., a material that performs a predetermined, reversible action in response to a change in the environment. Nitinol recovers a given shape, changes its resistivity drastically and modifies its elastic properties if…

A convenient laboratory experiment is described in which NMR magnetization transfer by inversion recovery is used to measure the kinetics and thermochemistry of amide bond rotation. The experiment utilizes Varian spectrometers with the VNMRJ 2.3 software, but can be easily adapted to any NMR platform. The procedures and sample data sets in this…

Explains the teaching opportunities, especially in science activities and laboratory experiments, of using technology in science classrooms. (YDS)

Attempts to answer two research questions: (1) Does the use of a digital camera in laboratory activities increase student learning?; and (2) Does the use of digital cameras motivate students to take a greater interest in laboratory work? Results indicate that the digital camera did increase student learning of process skills in two biology…

Describes the implementation of a new laboratory-based, interdisciplinary undergraduate course on linear dynamical systems. Focuses on geometrical methods and data visualization techniques. (Contains 20 references.) (Author/YDS)

This document presents a science experiment demonstrating the scientific method. The experiment consists of testing the fermentation capabilities of yeasts under different circumstances. The experiment is supported with computer software called BioLab which demonstrates yeast's response to different environments. (YDS)

Describes the benefits of using calculator-based laboratory equipment in science classes. (WRM)

Reviews emerging applications of microcomputers and hypermedia to assessment. Use consists mainly of computerized test administration of multiple-choice tests drawn from item banks. Significant advantages are possible in several areas including immediate feedback to students, formative evaluation with remediation possibilities, and monitoring…
