This book collects the proceedings of the 7th International Conference on Smart Learning Environments (ICSLE2023), held in Bangkok, Thailand, as a hybrid conference from 31st Aug to 1st Sep 2023. The proceedings focus on the interplay between pedagogy and technology, and their fusion towards the advancement of smart learning for a sustainable…

The solvent influence on the absorption spectra and the kinetics of the back reaction of the 1',3'-dihydro-1',3',3'-trimethyl-6-nitrospiro(2H-1-benzopyran-2,2'-2H-indole) (6-NO2-BIPS) has been investigated by means of temperature-controlled, UV-visible spectroscopic measurements. The back reaction process was proved to follow first-order kinetics…

An inexpensive procedure for introducing the Suzuki-Miyaura coupling reaction into a high-enrollment undergraduate organic chemistry laboratory course is described. The procedure employs an aqueous palladium solution as the catalyst and a range of para-substituted aryl bromides and arylboronic acids as substrates. The coupling reactions proceed…

An undergraduate laboratory experiment for the volumetric quantitative analysis of ascorbic acid and iron in dietary supplement tablets is presented. Powdered samples of the dietary supplement tablets were volumetrically titrated against electrolytically generated reagents, and the mass of dietary reagent in the tablet was determined from the…

The thermodynamic criteria for spontaneity and equilibrium in multireaction systems are developed and discussed. When N reactions are occurring simultaneously, it is shown that G and A will depend upon N independent reaction coordinates, ?a (a = 1,2, ..., N), in addition to T and p for G or T and V for A. The general criteria for spontaneity and…

The present paper gives an overview of research on heterogeneity and diversity in German chemistry classes. The terms "heterogeneity" and "diversity" are first explained before discussing specific studies. The different facets of heterogeneity and diversity are asserted. Finally, the focus will be placed on language and special…

A model scanning probe microscope, designed using similar principles of operation to research instruments, is described. Proximity sensing is done using a capacitance probe, and a mechanical linkage is used to scan this probe across surfaces. The signal is transduced as an audio tone using a heterodyne detection circuit analogous to that used in…

We demonstrate that the formula for irreversible expansion work in most chemical thermodynamics textbooks does not apply during the expansion process. Instead of the "external pressure" P[subscript ext], the pressure P[subscript sys,mb] on the piston or other moving boundary (hence the subscript mb), which is nearly equal to the system…

EU policy makers are facing increased urgency to integrate and energise the professional labour market, especially in the context of the fallout of the COVID-19 pandemic, the push towards the green and digital transitions and the defence of the Single Market following Brexit. This latest policy briefing on the recognition of professionals looks at…

In this article, we apply Max Weber's ideal types of fief and benefice feudalism to elite and non-elite chemistry departments in the USA. We develop a theoretical analogy of academic feudalism in regard to three dimensions: power relations, engagement with companies, and the impact of structural changes on the autonomy of scholars. We use a mixed…

The Scientific Computing for Chemists course taught at Wabash College teaches chemistry students to use the Python programming language, Jupyter notebooks, and a number of common Python scientific libraries to process, analyze, and visualize data. Assuming no prior programming experience, the course introduces students to basic programming and…

The national curriculum for chemistry includes topics that have not previously been taught at secondary level. In response to requests for teacher professional learning (PL) covering these topics, a course called "Divide and Analyse" was developed. Investigations into the PL needs of chemistry teachers were carried out in conjunction…

Concept inventories have been determined to be useful assessment tools for evaluating students' knowledge, particularly in the sciences. However, these assessment tools must be validated to reflect as accurately as possible students' understanding of concepts. One possible threat to this validation is what previous literature calls the item order…

The effect of intervention activities on the chemistry content knowledge of 92 preservice chemistry teachers (PSCT) was examined via a pre and post true/false with confidence level test focusing on ionisation energy values and the use of a common alternative conception (AC). Data were collected from three cohorts of PSCT each engaged in a one year…

Ensuring that all students who want to pursue degrees and careers in science can do so is an important goal of a number of undergraduate STEM equity programs throughout the United States. Many of these programs, which promote diversity and the importance of diversity in science, directly address the 2012 PCAST report, which notes that "1…
