Abstract:
Restrictions on physical gathering due to COVID-19 has compelled higher education institutions to rapidly embrace digital technologies to support teaching and learning. While logistically, the use of digital technologies offers an obvious solution, attention must be given to these methods' pedagogical appropriateness, mainly how students engage and learn in the spaces supported by these technologies. In this context, we explored the degree to which digital technologies have contributed to teaching and learning practices over the past decade. The study employed a systematic review using a newly developed tripartite model for conducting and presenting literature review reports. The model approaches the literature review process systematically and employs three phases for the critical examination of literature: description, synthesis, and critique. The current review focused on student engagement across technologies that encompass social media, video, and collaborative learning technologies. Relevant articles were obtained from the Scopus and Web of Science databases. Three core themes were identified: there was no shared understanding of what constitutes student engagement with learning technologies, there was a lack of explanation concerning the contextual variation and modalities of student engagement across the digital technologies, and self-reporting was the primary method of measuring student engagement, rendering results as perceptual rather than behavioural. We argue that using multiple datasets and different methodological approaches can provide further insights into student engagement with digital technologies. This approach to measuring engagement can substantiate findings and most likely provide additional insights into students' engagement with digital technologies.

Synaptic Signaling
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.
The presynaptic neuron fires an action potential that...
