ABSTRACT
Active learning methods have established significance in the teaching-learning of science and mathematics. This study investigated the understanding, beliefs, self-efficacy, practices, and challenges of active learning among upper primary school (grades 7 and 8) science and mathematics teachers in Ethiopia. Data were collected from 155 teachers drawn from nine schools of Addis Ababa, Amhara, and the Southern Regional States using validated questionnaires and observation. Descriptive analysis was employed to make meaning of the collected data. The result showed that teachers lack to have an appropriate understanding of active learning. But they have shown fairly consistent positive belief and self-efficacy about the outcomes of active learning if they use them in their classes. Teachers believed that they implement active learning to a higher extent. The result further indicated that teachers differ in their understanding, practices, and efficacy of active learning across their gender and educational levels. High teaching load, large class size, lack of teachers' motivation, shorter instructional time, the subject they teach, absence of guidelines for active learning methods at school, and lack of appropriate knowledge and skill of active learning methods were the common challenges reported by teachers. The findings of this study imply that there is a need to enhance teachers' understanding of active learning and to provide continuous support to them to use active learning even in challenging situations.
ABSTRACT
The COVID-19 pandemic highlighted the importance of transparency, open, and timely access to information. Open Access (OA) has the potential to increase the exposure and use of not only published research but also authoritative and reliable information. The Coronavirus (COVID-19) impacted the work of journalists, scientists, and doctors while ordinary citizens are seeking trusted information sources and the truth about the new virus. Government and private institutions worldwide are reacting to the new situation where researchers, educators, students, and staff are trying to adjust to remote teaching and learning as well as telecommuting. In March 2020, a message from the White House was sent to the Scholarly Publishing Community asking them to make all COVID-19 papers openly available and machine readable. Considering the evolving and unresolved issues around OA and scholarly communications, together with the UN 2030 Agenda (a plan of action for sustainable, universal development), this panel brings together diverse perspectives to review the current landscape of OA and shed light on the role it plays in such crises. The panel will also discuss the future implications and impact of the pandemic in the overall advancement of scholarship in general.
ABSTRACT
BACKGROUND: HIV infection has been modifying both the epidemiology and outcome of parasitic infections. Hence, this study was undertaken to determine the prevalence of intestinal parasitic infection among people with and without HIV infection and its association with diarrhea and CD4 T-cell count. METHODS: A cross-sectional study was conducted at Hawassa Teaching and Referral Hospital focusing on HIV positive individuals, who gave blood for CD4 T-cell count at their first enrollment and clients tested HIV negative from November, 2008 to March, 2009. Data on socio-demographic factors and diarrhea status were obtained by interviewing 378 consecutive participants (214 HIV positive and 164 HIV negative). Stool samples were collected from all study subjects and examined for parasites using direct, formol-ether and modified acid fast stain techniques. RESULTS: The prevalence of any intestinal parasitic infection was significantly higher among HIV positive participants. Specifically, rate of infection with Cryptosporidium, I. belli, and S. stercoralis were higher, particularly in those with CD4 count less than 200 cells/microL. Diarrhea was more frequent also at the same lower CD4 T-cell counts. CONCLUSION: Immunodeficiency increased the risk of having opportunistic parasites and diarrhea. Therefore; raising patient immune status and screening at least for those treatable parasites is important.
