The Covid-19 pandemic has become a world problem now. The pandemic has affeected a lot of core sectors including the education sector. Students are not able to go to school to study and have to do a social distancing by staying at home. What the government did so that students will still be able to study at home is by developing a long-distance learning media. In this research, we will get to know more about how students in China learn mathematics at home and their learning attitude towards the learning video. This research will use a qualitative and quantitative research method. The researchers gave out questionnaires to 408 students in Guangxi province, China. The researchers also did an interview on the parents and students to know the advantages and disadvantages of using the learning video during this covid-19 pandemic. The research result shows that there is a good student learning attidude towards the learning video. Students feel that the learning video is very interesting yet effective as they were able to understand the concept taught.

Aunque el desarrollo de la tecnología en el campo educativo ha promovido cambios progresivos en la metodología de enseñanza, especialmente a nivel universitario, en el último cuarto de siglo, se debe a la pandemia que afecta a la humanidad (COVID-19) cuando desde el contexto académico allí Ha sido la necesidad urgente de repensar todas las posibilidades de operación y sin contacto basadas en Internet a través de la enseñanza sincrónica o asincrónica. Thus, with the development of MOOCs, great possibilities have been seen to meet educational demands in a non-face-to-face way, enabling individualized and open attention to the group of students who present cases and varied needs. In the present work, we intend to carry out an approach to MOCCs in terms of conceptualization, characteristics, elements and typologies, deepening their relationship with educational care in the pandemic moment that surrounds us. To finish, we will make a tour of various MOCC aggregators / search engines and we will copy several of them to demonstrate their educational potential.

This cross-sectional study was aimed to describe and analyse factors related to the professional well-being of Portuguese teachers during the COVID-19 pandemic. A previously validated, anonymous and online questionnaire was applied to a non-probabilistic sample of Portuguese teachers. In addition to the socio-demographic and professional variables, the questionnaire measured subjective and professional well-being, satisfaction with the education system and future perspectives regarding the professional circumstances. The psychometric characteristics of the questionnaire were analysed, the t-test and ANOVA were used to analyse the differences between the main variables and the socio-demographic and professional characteristics, along with the generalized linear model in order to more precisely determine the predicting factors of teachers' professional well-being. The results showed that the majority of respondents have a moderately positive perception of well-being. Teachers were satisfied with the education system before the pandemic. The pandemic has reduced the perception of well-being in the face of the profession, creating some concern among teachers about their professional future. Sex, length of service, well-being, perceptions of teaching difficulties and future perspectives proved to be predictors of professional well-being in times of pandemic. This study provided scientific bases for the development of interventions that improve the professional well-being of teachers, which focus on emotional management and the development of digital skills in teachers with long careers. This piece of research concluded with thorough evidence that there is a need for further and stronger investment in public policies for the reform and, consequently, for the renewal of the teaching class.

The health context related to the COVID-19 virus has implied challenges for several areas, among them the educational field stands out. The research project known as DIFPRORET covered various educational challenges; however, in this specific article, the aim is to analyze the perception of 112 people about the use of digital platforms through three questions: the educational difficulties encountered in the period of confinement, the main challenges we must overcome to address education in periods of confinement, and what are the most relevant proposals made by the subjects in this period. For the analysis of the questions, multivariate analyses were employed: multidimensional scaling and hierarchical clusters. It was observed that two of the main educational difficulties are the organization of time and the preparation of activities in confined contexts. Nevertheless, the proposals point to different levels that go from individual competences of the student-teacher to the society, with the discussion on the access to resources. This corresponds to a broader dimension such as social inequality.

COVID-19 has disrupted the lives of humans causing devastating health effects and life of a large part of the world population, affecting the social, economic and educational spheres of the planet. The scientific community is facing one of its greatest challenges to solve a global health problem such as the COVID-19 pandemic. This situation has generated an unprecedented volume of publications. The impact of COVID-19 on teaching has meant that moments of social contact have disappeared in exchange for meetings, classes, exams or virtual meetings. In this scenario, the university classrooms when reopened will not be the same, nor will their campuses or spaces in the educational field. The objective of the study was to identify scientific publications related to the effects of COVID-19 in university classrooms during the period 2019 to the present. For this, a bibliometric analysis of the scientific literature was performed. Thus, 676 documents were identified on this subject. The results of the analysis revealed that scientific productivity has increased since January 2020 with more than 650 articles on the disease, verifying the deep interest in COVID-19 in all disciplines. The main research trends include the impact of returning to the classroom with the effects on the cognitive processes, motivations and academic performance of students

The purpose of this communication letter is to present a theoretical didactic proposal for addressing the problems of school coexistence after COVID 19, from the use of coaching tools. Proposal that will allow us to better manage coexistence and its possible conflicts, once the thousands of students return from their quarantines and normal schooling processes begin. As a methodology, firstly, an introduction, a brief theoretical framework to explain and understand this proposal, a methodology and its corresponding didactic action of the model are presented, which includes the general procedures for action of the model, the didactics to implement this proposal, which includes a plan for the prevention and treatment of coexistence, and the corresponding conclusions, which give meaning to the theoretical didactic proposal for addressing the problems of school coexistence. In this, it will allow all members of the school coexistence team to be prepared so that, through the tools, techniques and practical work of educational coaching, both in prevention topics, and in strategies to face these new problems that covid will bring 19. It is not known, how long this period of compulsory school distance will last, if it can be hypothesized that it will greatly affect coexistence in the thousands of quarantined children and youth.

Faced with the unexpected state of alarm decreed due to the pandemic produced by Covid-19, Spanish universities have been forced to adapt teaching to this situation, using Information and Communication Technologies as the primary means. Most teachers have had to make an abrupt transition to do our classes online. This experience has probably been hectic and yet perhaps an educational and revealing experience for many of us. Of all the changes, the most substantial is to move from face-to-face teaching to online teaching-learning, this change requires a series of adjustments in education that must be assumed from the re-planning of the subject to the delivery of classes in virtual mode. They have also had to adapt the spaces of the university since the exams that were presential to virtual have been replanned.

Technology has been instrumental for efficient communication to counter the pandemic that the world is facing today. It also redefines how the educational system can proliferate the delivery of the teaching-learning process amidst COVID-19. This paper articulates the effectiveness of distance education, highlights the possible challenges in emergency remote education, and recommends emerging remote learning platforms along with policies for the utilisation of emergency remote teaching and protocols for the prevention of COVID-19 in Philippine learning institutions. The paper offers further research of innovative strategies, virtual learning experiences, and the transition from the physical classroom into an emergency remote education environment during the pandemic.

Se optimizaron las condiciones de extracción mecánica de hidrocoloides de hojas de Malva sylvestris y determinó el comportamiento reológico y actividad antioxidante. Las hojas fueron hidratadas en 15, 20 y 25 g de agua/g de hojas polvo, por 30, 60 y 90 min, luego solubilizadas por expresión mediante paletas a presión de 53 db y 424, 508 y 592 mov/min por 60, 120 y 180 s. La reología en soluciones al 0,7, 1,4 y 2,1% (p/v) a 20, 30 y 40 °C se efectuó con reómetro y la actividad antioxidante a 20, 40, 60 y 80 °C se realizó cuantificando polifenoles totales y captación de radicales libres con los métodos de Folin-Ciocalteu y DPPH respectivamente. Del estudio se concluye, que para obtener rendimiento máximo en la extracción de 19,21% (p/p), las condiciones óptimas se ajustaron a modelo de segundo orden con hidratación de 25 g de agua/g de hojas polvo por 30 min y solubilización a 592 mov/min por 180s. Los reogramas obedecieron al modelo de Ostwald, mostrando los hidrocoloides ser fluidos pseudoplásticos. Los polifenoles totales (mg AGE / 100 g muestra) de 20 a 80 °C, disminuyó de 131,17 a 78,87 y la captación de radicales libres DPPH (mM Trolox / g muestra) de 60 a 80 °C decreció de 0,422 a 0,298.

El objetivo del presente trabajo fue evaluar los beneficios y eficacia del tratamiento de coagulación y floculación de las aguas residuales provenientes de un matadero. Para ello se analizaron muestras de 500 ml y se utilizó sulfato de aluminio (1%) y cloruro férrico (1%) como agentes coagulantes, polímero catiónico (1%) como agente floculante y gradientes de velocidad alta (150 – 300 r.p.m) y velocidad baja (37 – 75 r.p.m).  Las concentraciones iniciales de contaminantes en el efluente fueron: pH (6,98 – 6,97), turbiedad (436 - 537 NTU), SST (430,6 – 228,8 ppm), oxígeno disuelto (1,17 – 2,11mg/L), nitratos (0 – 7,5 mg/L). Los mejores resultados se obtuvieron con la adición de 6 ml de sulfato de aluminio; 1 ml de polímero catiónico, una velocidad de mezcla de 200 r.p.m y un tiempo de sedimentación de 25 minutos, que disminuyeron las concentraciones de turbiedad 4,85 NTU, oxígeno disuelto 9,16 mg/L y STD 333,6 ppm. Asimismo, la adición de 2 mL cloruro férrico, 0,75 mL de polímero catiónico, una velocidad en mezcla rápida de 300 r.p.m y tiempo de sedimentación de 35 minutos, permitieron obtener como resultado 15,46 NTU, oxígeno disuelto 9,45 mg/L, STD 224,7 ppm, nitratos 6 mg/L.
