Computational chemistry is commonly addressed in the quantum mechanics course of undergraduate physical chemistry curricula. Since quantum mechanics traditionally follows the thermodynamics course, there is a lack of curricula relating computational chemistry to thermodynamics. A method integrating molecular modeling software into a semester long…

A drug discovery project has been successfully implemented in a first-year general, organic, and biochemistry (GOB) health science course and second-year organic undergraduate chemistry course. This project allows students to apply the fundamental principles of chemistry and biology to a problem of medical significance, practice basic laboratory…

A three-tiered experiment for undergraduate Instrumental Analysis students is presented in which students characterize the solid-state thermal behavior of an active pharmaceutical ingredient (acetaminophen) and excipient (a-lactose hydrate) using differential scanning calorimetry, thermogravimetric analysis, and thermal microscopy. Students are…

In this laboratory experiment, students determine the number-average molar masses and second virial coefficients of polyethylene glycol (PEG) polymers ranging in molar mass from 200 to 1500 g mol[superscript -1] using vapor pressure osmometry (VPO). Students assess VPO in relation to accurate molar mass calculations of PEG polymers. Additionally,…

Many introductory and nanotechnology textbooks discuss the operation of various microscopes including atomic force (AFM), scanning tunneling (STM), and scanning electron microscopes (SEM). In a nanotechnology laboratory class, students frequently utilize microscopes to obtain data without a thought about the detailed operation of the tool itself.…

Contribution: A model of tiered in-lab, compulsory lab programming sessions suitable for use in flipped learning environments. This article also addresses the scarcity of research that explores the effects of in-class activity organization. Background: When facing a subject they perceive as dry or difficult, some students may feel discouraged from…

Structured collaborative peer teams are widely recognized as a high-impact pedagogy that supports learning outcomes for diverse learners but it can be difficult to implement this pedagogy in an online environment. This communication describes a structure to use collaborative teams to develop and sustain a community of inquiry in an asynchronous…

This multiple case study used the lens of identity to investigate how three beginning science teachers deal with practical work during their first two years of teaching careers in high school. In-depth data were collected from multiple sources for the three participants and data analysis was focused on the interactions between personal,…

Embedded system is an interdisciplinary, profound foundation and practice-oriented course; at present, in the traditional teaching mode, embedded systems in colleges and universities generally have problems such as disconnected theory and practice, outdated assessment methods, and low enthusiasm of students. Arming to cultivate compound embedded…

In contrast to traditional science instruction, which encourages students to memorize facts from textbooks, today's science instruction emphasizes the adoption of scientific process skills by students, as well as the teaching of critical thinking skills. Lebanese Chemistry teachers detected lack in middle school and high school students' critical…

Challenge-based learning (CBL) is a multidisciplinary approach that encourages students to work actively with peers, teachers and stakeholders in society to identify complex challenges, formulate relevant questions and take action for sustainable development. In this paper, it is argued that CBL can be viewed as an evolution of the Conceive,…

The Texas Woman's University Future Classroom Laboratory (TWUFCL) is a unique learning space designed for use by university faculty, future teachers, and local PreK-12 teachers and students. Part of the European Schoolnet's Network of Future Classroom Labs, the TWUFCL offers users the chance to explore the science of teaching and learning in a…

In the past decades, society in general has become strongly diverse. This change also affects schools. As a result, learning groups cannot be seen as homogeneous and taught in this way. One of the challenges is students' linguistic skills. Dealing with different linguistic competencies should not only be a focus of formal education in schools but…

Electrospray ionization mass spectrometry (ESI-MS) is a powerful tool for examining the charge of proteins in solution. The charge can be manipulated through choice of solvent and pH. Furthermore, solution-accessible, protonated lysine side chains can be specifically tagged with 18-crown-6 ether to form noncovalent adducts. Chemical derivatization…

Electrospray ionization-mass spectrometry (ESI-MS) is a powerful technique for the detection, identification, and quantification of organic compounds. As mass spectrometers have become more user-friendly and affordable, many students--often with little experience in mass spectrometry--find themselves needing to incorporate mass spectrometry into…
