New Pub: ChatGPT in Education

Journal, New Pub, Research Methods
Early studies on the usage of ChatGPT in educational settings have reported substantial learning gains from ChatGPT applications. But how valid are these studies? Is using ChatGPT in education really as effective as it seems? A newly published paper takes a deeper look at key findings from past debates about media and teaching methods to reveal frequent conceptual challenges that arise in studies about the effectiveness of ChatGPT. When researchers compare different types of media for learning, they sometimes mix up the effects of the teaching style with the features of the technology. If the instructional methods and the technological features are confused with one another, it makes it difficult to be able to interpret the actual effect of ChatGPT. To help pinpoint the conceptual difficulties of these efficacy studies,…

New Pub: Preserving Privacy in Multimodal Learning Analytics with Visual Animation of Kinematic Data

Empirical Study
A recent study has been published that addresses the growing concern of data privacy in multimodal learning analytics (MMLA). The research investigates the potential of using visual animations as an alternative to traditional video recordings for analyzing sensitive data, particularly in educational settings. MMLA involves collecting and analysing data from various sources, including video recordings, to gain insights into learning behaviours and outcomes. However, the use of video can raise significant privacy concerns, especially when it contains identifiable information about individuals. This has led to ethical dilemmas regarding using such data in research. The study, based on the master thesis of Aleksandr Epp, introduces the Kinematic Animation Tool (KAT) to address these privacy issues. This tool allows researchers to visualise kinematic data without relying on video footage, thereby mitigating privacy…
