Towards improving learning experiences in self-paced online learning courses
Authors: Gumbo Sibukele , Twinomurinzi Hossana
Published: May 2023

One of the key goals of higher education institutions (HEIs) is student career success. In HEIs, students are given the necessary subject-specific information, skills, and experience to achieve this. In South Africa, which has historically been one of the technological leaders in Africa, there are currently insufficient Fourth Industrial Revolution (4IR) specialists graduating from higher education to meet the rising need for a skilled workforce in those fields. The completion rate of supplementary online courses to expand this 4IR skills base is also a major concern. In this paper, we report on the strategy implemented to improve the course completion rate of a self-selected sample of students who attended face-to-face Data Science introduction workshops in the Eastern Cape province of South Africa. We achieved a 76% completion rate of two MOOCs courses in these workshops. We examined the contribution of the participant’s personal factors and background contextual factors. We also listed any other factors suggested by the students, which collectively contribute to the learning experience construct of the social cognitive career theory (SCCT) and serve as a practical means of improving 4IR skills exposure and the outcome expectations. Therefore, this paper shows the mechanism which can be used to offer 4IR programmes, in HEIs, to raise students' self-efficacy and outcome expectations in fields such as Data Science. In addition, the learning experience inputs can be utilized to increase students' interest in majoring in 4IR courses.

Affordances of an international campus for intercultural learning: Views from MA students and faculty in two US-based teacher education programs
Authors: Lazarević Nina
Published: May 2023

This paper reports on a qualitative study which is part of a larger project on the affordances of an international campus for intercultural (IC) learning. The research examined two MA programs at a US postgraduate institution, TESOL and International Education Management, and two groups of participants, 9 students and 8 faculty members. The participants discussed intercultural interaction and learning opportunities outside coursework in semi-structured interviews. A thematic content analysis showed heavy workload as an obstacle to more meaningful on-campus interaction, the lack of the points of entry to host-country student groups for incoming (international) students, and challenges for off-campus encounters. The findings pointed to a disconnect between faculty and student perceptions: although faculty believed that students should avail themselves of IC opportunities, they did not actively encourage engagement in on-campus activities. The paper discusses the IC learning assumptions attached to a highly international program profile in comparison to the support in place, arguing that active on- and off-campus activities, coursework, and teacher guidance should work in unison to allow for IC learning.

Published: May 2023

A correlation analysis is needed to see the relations among the three variables, rainfall with El Niño-Southern Oscillation (ENSO) and Humidity with ENSO. The instability of rainfall and the decrease in the humidity in Bengkulu City can be affected by La Nina and El Nino phenomena. This research aimed to analyze the correlations among rainfall, humidity, and ENSO with Pearson correlation analysis. The rainfall and humidity data were collected from BMKG, and the ENSO data were obtained from NOAA PSL for the 1985-2020 period. The results of the correlation analysis of rainfall and ENSO for the last 35 years generally show a moderately strong correlation. However, a strong correlation in the La Nina phase specifically occurred in 1988-1989, 1998-1999, 1999-2000, 2007-2008 and 2010-2011 with values of 58.6, 40.1, 61.4, 96, 4, and 89.2%. Meanwhile, the correlation >80% (very strong) during the El Nino phase occurred in 1987, 1991-1992, 1997, 2015. The correlation analysis results of humidity and ENSO show little correlation in the La Nina phase of >70% (1988-1989, 1998-1999, 2010-2011) and the El Nino phase of <70% (1997, 2015, 2016). The humidity correlations with ENSO do not influence the humidity change in Bengkulu City. The decrease in the humidity in Bengkulu City can be affected by other factors, such as land use change to housing due to population growth in Bengkulu City.

A set of seven promising inbred lines were involved in half-diallel mating design to study the combining ability effects for grain yield and yield contributing characters. The experimental material consisted of seven parents and their 21 crosses along with five public/private checks. Yield trials were conducted at three environments during Kharif 2015. Mean squares due to environments were highly significant for all the traits except kernels row-1 indicating that these traits were highly influenced by environment factors. Hybrids × environment and hybrids Vs parents × environment interaction was significant for ear length, grain yield and fodder yield. GCA × environment and SCA × environment (P < 0.05) interactions were significant for plant height, ear length and fodder yield traits. The magnitude of the interaction of SCA × environments is higher than GCA × environments for flowering and maturity traits, kernel rows ear-1 , shelling %, 100 kernel weight, grain yield for combined analysis over three environments. GCA/SCA ratio was less than unity for all the studied traits indicating non additive gene action plays a major role in controlling the traits. Across the environments, BML-51 was a good general combiner for days to 75% dry husk, plant height, ear height, ear length, shelling %, 100 kernel weight, grain yield and fodder yield. BML-13 and BML-10 were good general combiners for flowering traits. Among the crosses, BML-51 × BML-14 had significant and positive SCA effects with high mean values in all three environments and pooled over environments for grain yield and fodder yield.

The manifestation and severity of Allergic rhinitis symptoms show diurnal variation which negatively impacts the patient’s quality of life, day-to-day activities, and productivity at the workplace. The symptoms worsen at night or early morning and therefore administration of levocetirizine towards evening may be more acceptable. Consequently, the present study evaluated the effectiveness of evening Levocetirizine administration on 24-hour symptom control, Physical and mental health, and daytime somnolence in patients with allergic rhinitis the study was a prospective, open-labeled, single-arm, two-center, observational study among patients with allergic rhinitis. Levocetirizine was prescribed as 5 mg or 10 mg once a day evening oral dose for at least 7 days before sleep. The 24-hour total nasal symptom scores (TNSS) for self-reported signs and symptoms of allergic rhinitis were recorded. Additionally, study evaluations included the SF-12 scale (Quality of Life), Stanford Sleepiness Scale (degree of sleepiness), and work productivity and activity impairment (WPAI) questionnaires. These evaluations were performed at baseline (Day 0) and at scheduled intervals of Day 1 (24-hour), Day 3, and Day 7. Results demonstrated that evening administration of Levocetirizine facilitates 24-hour symptom control while having no significant effect on daytime somnolence, daily activities, and the work productivity of patients.
