Through a study of digital composing in LGBTQ+ YouTube reaction video channels, I explore the role of emotion in shaping how writers in virtual communities collectively feel about injustice and write for social change. In the reaction videos, vloggers circulate funny, emotional reactions to anti-LGBTQ+ media undergirded by oppressive ideologies…

This study focuses on the effect of cyberostracism on social networking sites. Based on the temporal need-threat model of ostracism, we examined a) reflexive reactions, specifically worsened mood and threats to the four fundamental needs (i.e., belongingness, self-esteem, meaningful existence, and control), and b) reflective reactions, in the form…

The study examines an important aspect of the training evaluation, namely trainee reaction to training. In particular, the author aimed to analyse the relationship between learning self-efficacy during the training and identified factors of trainee reaction to training: trainee perception of the training content, design, and trainer performance.…

Digital video has become a dominant form of student learning in and beyond the classroom, and thus its pervasive nature in contemporary learning environments commands scholarly inquiry. In this paper we explore a participatory design-based research approach to the integration of video hook technology in the post-primary science classroom (students…

Since the spring of 2020, the pandemic has dominated public discourse. Using a public health critical race praxis research approach, our team interviewed a diverse group of individuals to elicit stories about their knowledge, attitudes, and responses to COVID-19. We used health belief model constructs and critical race theory tenets to evaluate…

A one-pot regio- and stereoselective synthesis of a dipyrromethane and a bis(indolyl)methane based on two consecutive reactions of nitrosoalkenes with pyrrole or indole, respectively, is described as an experiment to be carried out by upper-division undergraduate students in a laboratory classroom. Importantly, the ability of electrophilic…

We present an experiment designed to hone the decision-making skills of (undergraduate) chemistry students by using aqueous crossed aldol reactions. Here, we present two simple crossed aldol reactions based on inexpensive and readily available materials: The condensation of vanillin and cinnamaldehyde with acetone. The procedure uses the variation…

Errors are natural elements of the learning process and provide a high potential to promote students' learning outcomes. In recent years, there has been much research about learning from errors. However, we know little about the relationship between students' error beliefs in chemistry and chemistry learning outcomes at present. Thus, the aim of…

An understanding of acid-base reactions is necessary for success in chemistry courses and relevant to careers outside of chemistry, yet research has demonstrated that students often struggle with learning acid-base reaction mechanisms in organic chemistry. One response to this challenge is the development of educational applications to support…

This study investigates whether students with intellectual disability (ID) alone differ from students with combined individual disability and autism spectrum disorder (ASD) in their recognition of emotions. The ability to recognise emotions does not mean that students automatically know how to react to these emotions. Differences in performance on…

Regioselectivity in hetero Diels-Alder reactions can be observed in a simple reaction between a nonsymmetrical heterodiene and an unsymmetrical heterodienophile. A 9 h and easy to implement laboratory experiment is described, in which students can observe the regioselectivity of inverse "electron-demand" hetero Diels-Alder reactions of…

The mathematical method of linear equations involving the coefficients of the equation of a chemical reaction can be used to balance the equation of nearly every chemical reaction. For its application, only the rules of simple algebra need be known. Hence, the method could even be used by students of an elementary chemistry course.

Protein PEGylation refers to the covalent binding of polyethylene glycol (PEG) moieties to a protein and has been increasingly applied, mainly in the biopharmaceutical industry. This technique may increase bioavailability and stability by decreasing immunogenicity and proteolytic attack. Given the industrial interest and the relevance of this…

Research has shown that within a traditional organic chemistry curriculum, organic chemistry students struggle to develop deep conceptual understanding of reactions and attribute little meaning to the electron-pushing formalism. At the University of Ottawa, a new curriculum was developed for organic chemistry in which students are taught the…

We present a course-embedded undergraduate research module that involves real-time polymerase chain reaction testing for the presence of SARS-CoV-2 in environmental samples. A positive control RNA was constructed and two RNA extraction methods were compared and a range of primers were available to compare. Using a combination of published…
