The onset of the COVID-19 pandemic across the globe resulted in countries taking several measures to curb the spread of the disease. One of the measures taken was the locking down of countries, which entailed restriction of movement both locally and internationally. To ensure continuation of the academic year, emergency remote teaching and learning (ERTL) was launched by several institutions of higher learning in South Africa, where the norm was previously face-to-face or contact teaching and learning. The impact of this change is not known for the speech-language pathology and audiology (SLPA) students. This motivated this study.
This study aimed to evaluate the impact of the COVID-19 pandemic on SLPA undergraduate students during face-to-face teaching and learning, ERTL and transitioning towards hybrid teaching and learning.
Using course marks for SLPA undergraduate students, K means clustering and Random Forest classification were used to analyse students' performance and to detect patterns between students' performance and the attributes that impact student performance.
Analysis of the data set indicated that funding is one of the main attributes that contributed significantly to students' performance; thus, it became one of the priority features in 2020 and 2021 during COVID-19.
The clusters of students obtained during the analysis and their attributes can be used in identification of students that are at risk of not completing their studies in the minimum required time and early interventions can be provided to the students.
全球范围内 COVID-19 大流行的爆发导致各国采取了多项措施来遏制疾病的传播。其中一项措施是封锁国家,这意味着限制国内和国际的人员流动。为了确保学年的继续,南非的几所高等院校推出了紧急远程教学(ERTL),而之前的规范是面对面或接触式教学。这种变化对言语语言病理学和听力学(SLPA)学生的影响尚不清楚。这促使了这项研究的开展。
本研究旨在评估 COVID-19 大流行对 SLPA 本科学生在面对面教学、ERTL 以及向混合教学过渡期间的影响。
使用 SLPA 本科学生的课程成绩,使用 K 均值聚类和随机森林分类来分析学生的表现,并检测学生表现与影响学生表现的属性之间的模式。
数据分析表明,资金是对学生表现有重大贡献的主要属性之一;因此,它成为 2020 年和 2021 年 COVID-19 期间的优先考虑因素之一。
分析中获得的学生聚类及其属性可用于识别可能无法在最短时间内完成学业的学生,并为学生提供早期干预。
