ABSTRACT
The COVID-19 crisis emphasizes the importance of Self-Regulated Learning (SRL), one of today’s most valuable skills, with which learners set their learning goals, monitor and control their cognition, motivation, and behavior, and reflect upon them. In the current experimental study, an intervention program based on short online interactive videos was developed to promote SRL skills. This paper presents the impact of the intervention on students’ use of SRL skills and grades. It also explores four key pedagogical processes (teacher-student relationships, collaboration, autonomy, and feedback) as mediators for SRL strategies use and grades. The experimental and control groups were randomly assigned (N = 290 students, 18 classes, grades 7–12). Each teacher taught the same subject in two classes for a month, an amount of time that allows intervention to take effect. One of the classes participated in the video-based intervention program (experimental group), whereas the other performed all activities but did not have access to the videos (control group). Data was collected through an SRL and pedagogies usage questionnaire, SRL video prompts, and knowledge tests and was analyzed using the quantitative method. In addition to the theoretical contribution, a practical tool has been developed for educators who wish to employ online SRL training. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
This study was undertaken to identify herbal remedies that may be involved in the symptomatic management of COVID-19 disease. From a list of 247 medicinal plants, a bibliographic study was carried out with the richness, the floristic composition, the methods of preparation and use and the active principles of the plants as a variable. The importance value of these plants was also calculated. A Principal Component Analysis showed the links between the parts of plants used, the methods of preparation, the symptoms of COVID-19 disease that can be treated and the active ingredients. The results show that 226 medicinal plants divided into 190 genera and 79 families can be used to treat the symptoms of COVID- 19 disease namely otolaryngologic signs, pulmonary signs and general signs. Of these, twenty-eight (28) can relieve the majority of symptoms of COVID-19 disease. These symptoms are rhinorrhea, cough, fever, headache, vomiting, diarrhea, and muscle aches. These plants are mainly prepared in the form of a decoction and administered mainly orally. They mainly contain flavonoids, coumarins, alkaloids, tannins, steroids, terpenoids, saponosides, essential oils, mucilages, quinones, coumarins. The importance value of these plants is between 85.71 and 57.14%. The results also showed that eight (8) groups of medicinal plants can be distinguished according to the organs used, the methods of preparation, the symptoms of the COVID-19 disease treated and the active ingredients. The results of this study could serve as a database for the formulation of improved traditional drugs in the management of symptoms of COVID-19 disease in Cote d'Ivoire.
ABSTRACT
We present a case of acute bilateral multifocal CSCR in a young healthy Caucasian female occurring 3 days after receiving the first dose of the Pfizer-BioNTech BNT162b2 COVID-19 mRNA vaccine. The true incidence of this adverse reaction might be underreported in asymptomatic unilateral or paracentral cases. We believe that the post-COVID-19 vaccination occurrence of CSCR is not a sufficient reason to withhold the second dose of the vaccine. Further studies are required to ascertain the best way to prevent and manage this complication.
