A syringe-based, electronic fluid dispenser is described. The device mechanically connects a syringe plunger to a linear slide potentiometer. As the syringe plunger moves, the electrical resistance between terminals of the potentiometer varies. Application and subsequent measurement of a DC voltage between the potentiometer pins is used to track…

Conducting experiments in physics using modern measuring techniques, and particularly those utilizing computers, is often much more attractive to students than conducting experiments conventionally. However, the cost of professional kits in the Czech Republic is still very expensive for many schools. The basic equipment for one student workplace…

The aim of this simple, quick, and safe laboratory exercise is to provide undergraduate students an introduction to nanotechnology using nanoparticle (NP) synthesis. Students are provided two procedures that allow for the synthesis of different yet controlled sizes of silver NPs. After preparing the NPs, the students perform UV-visible…

This advanced undergraduate laboratory experiment involves the synthesis and characterization of a metal-organic framework with microporous channels that are held intact via hydrogen bonding of the coordinated water molecules. The hydrothermal synthesis of Co[subscript 3](BTC)[subscript 2]·12H[subscript 2]O (BTC = 1,3,5-benzene tricarboxylic acid)…

A rapid separation of three photosynthetic pigments (chlorophyll "a" and "b" and xanthophyll) from fern ("Polystichum acrostichoides") is described using microscale solvent extraction and traditional thin layer chromatography that minimizes use of harmful chemicals and lengthy procedures. The experiment introduces…

This study investigates EFL Saudi male and female learners' and tutors' attitudes and practices in the Writing Centers at the College of Languages and Translation (CLTWCs) at Al-Imam Muhammad Ibn Saud Islamic University to determine the effectiveness of such centers. In fact, understanding EFL learners' needs is believed to eliminate some of the…

Base Pair is an ongoing (1992-present) collaboration between University of Mississippi Medical Center (UMMC) faculty mentors and Mississippi high school students and teachers. UMMC faculty and Base Pair teachers designed a course which has allowed curriculum innovations by teachers. The student component engages 15 trainees annually in laboratory…

Many studies have shown a decrease in scientific interest with an increase in age. Since interest is linked to a high degree of deep-level learning, it is of great relevance to foster interest in science. This study investigates interest in biology from 7th, 9th, and 12th grade students in Germany (N=257). Results show a significantly lower…

We implemented NSF-funded computerized Experimental Psychology Laboratories at Touro College and incorporated process-oriented guided-inquiry learning (POGIL). We designed POGIL modules for the labs and conducted workshops for faculty on the implementation of the guided-inquiry approach, including learning teams. Data were collected from students…

Multitouch learning books (MLBs) are learning companions that support learning within a series, independent of the learning location. These MLBs can accompany an experiment itself or an entire learning process. In addition to providing interactive tasks, an all-in-one solution can provide pupils with additional information, supporting and…

Currently, traditional paper methods may not effectively be used in education due to lack of access, outdated content, and poor graphics. Education through mobile-based applications is one of the alternative solutions. The objective of this study was to develop and evaluate LabSafety educational application and its effect on promoting the…

Knowledge of functional groups provides students with a language for organic chemistry. However, students in a health science chemistry course do not plan to be synthetic organic chemists and, therefore, need examples of how functional group chemistry is relevant to their vocational goals. We have developed a lab to demonstrate how simple…

Numerous American national committees have recommended the replacement of traditional labs with a more engaging curriculum that inspires inquiry and enhances scientific skills (examples include the President's Council of Advisors on Science and Technology (PCAST)'s Engage to Excel program and American Association for the Advancement of Science…

This post-professional development evaluation study (based on in-depth interviews) assessed the experience of ten educators who had participated one year earlier in workshops about the use of museum digital resources through the Smithsonian Learning Lab (SLL) for curricula development. The project focused on creating SLL collections to integrate…

This study aimed to analyze principals' managerial competency. The respondents of the study comprised of 11 principals and 110 teachers in the Laboratory High Schools (LHSs) of State Universities and Colleges (SUCs) in Region III, Philippines. The study used the Competency Framework for Southeast Asian School Heads, 2014 Edition formulated by the…
