    An observational study of teachers' and students' behaviors in synchronous online classrooms
    (2024) Gonzalez, Carlos; Ponce, Daniel
    PurposeThis paper aims first to describe the most prevalent teachers' and students' behaviors in synchronous online classes in emergency remote teaching; second, to discern behavior profiles and third, to investigate what features explain the observed behaviors.Design/methodology/approachAn adapted COPUS observation protocol was employed to observe 292 online classes from 146 higher education teachers.FindingsThe most prevalent behaviors were: Presenting for teachers and Receiving for students, followed by Teachers Guiding and Students Talking to Class. Furthermore, cluster analysis showed two groups: Traditional and Interactive. The variables that better explained belonging to the Interactive lecture group were disciplinary area - social sciences and humanities -and teaching in technical institutions.Practical implicationsIn a context where higher education institutions intend to project the lessons learned into post-pandemic learning experiences, this study provides observational evidence to realize the full potential expected from online and blended teaching and learning.Originality/valueDespite the prevalence of synchronous online lectures during COVID-19, there is a paucity of observational studies on the actual behaviors that occurred in this context. Most research has been based on surveys and interviews. This study addresses this gap.

    Extending research on 'conceptions of teaching': commonalities and differences in recent investigations
    (ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2011) Gonzalez, Carlos
    There is a significant body of research on conceptions of teaching. However, newer studies have reported facets of teaching which did not emerge in previous research. This has lead to claims that there may be still much to learn about university teachers' conceptions of teaching. In this line, the present study is aimed at exploring, from a phenomenographic perspective, conceptions of teaching in a multidisciplinary sample of university teachers. The focus was on undergraduate courses. Results obtained extended prior investigations by: (1) providing further empirical support to the teacher-focused/student-focused framework for analysing conceptions of teaching; (2) presenting a new dimension of variation and extending prior knowledge on them; and (3) providing further empirical support for conceptualising conceptions of teaching as related in a hierarchy where lower level conceptions are included in the higher level ones.

    Increased production of soluble TLR2 by lamina propria mononuclear cells from ulcerative colitis patients
    (ELSEVIER GMBH, 2012) Candia, Enzo; Diaz Jimenez, David; Langjahr, Patricia; Nunez, Lucia E.; de la Fuente, Marjorie; Farfan, Nancy; Lopez Kostner, Francisco; Abedrapo, Mario; Alvarez Lobos, Manuel; Pinedo, George; Beltran, Caroll J.; Gonzalez, Carlos; Gonzalez, Maria Julieta; Quera, Rodrigo; Hermoso, Marcela A.
    Toll-like receptor 2 (TLR2) is a type I pattern recognition receptor that has been shown to participate in intestinal homeostasis. Its increased expression in the lamina propria has been associated with the pathogenesis in inflammatory bowel disease (IBD), such as ulcerative colitis (UC) and Crohn's disease (CD). Recently, soluble TLR2 (sTLR2) variants have been shown to counteract inflammatory responses driven by the cognate receptor. Despite the evident roles of TLR2 in intestinal immunity, no study has elucidated the production and cellular source of sTLR2 in IBD. Furthermore, an increase in the population of activated macrophages expressing TLR2 that infiltrates the intestine in IBD has been reported. We aimed first to assess the production of the sTLR2 by UC and CD organ culture biopsies and lamina propria mononuclear cells (LPMCs) as well as the levels of sTLR2 in serum, and then characterize the cell population from lamina propria producing the soluble protein.

    Polarity of comments and internal consistency in peer review reports on scientific research articles
    (UNIV CHILE, CENTRO INTERDISCIPLINARIO ESTUDIOS BIOETICA, 2016) Astudillo, Cesar; Squadrito, Karem; Varas, German; Gonzalez, Carlos; Sabaj, Omar
    Peer review reports on scientific articles means a key genre to explain how scientific knowledge is collectively constructed. In these reports, reviewers write a recommendation for publication along with a series of comments. The quality analysis of the peer review process has been commonly conducted based on indicators, such as rejection rates and the agreement level among evaluators. However, a more qualitative investigation on the process still remains outstanding. This work aims at describing the polarity ( positive, negative and neutral) of comments corresponding to 56 peer review reports belonging to the journal Onomazein and determining whether this proportion is consistent with the reviewers recommendation, i.e. Accepted, Accepted with major revisions, Accepted with minor revisions and Rejected). After the analysis of 1.472 comments, it was possible to determine that the highest proportion of comments is negative, independent of the decision. The analyzed processes also showed a high level of consistency. The more favorable the recommendation, the higher the proportion of positive comments, and, consequently, the less the proportion of negative comments.

    What do university teachers think eLearning is good for in their teaching?
    (ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2010) Gonzalez, Carlos
    Although numerous studies have been conducted on conceptions of teaching, research extending this investigation into conceptions of teaching using eLearning is rare. This study employed a phenomenographic approach to investigate what university teachers think eLearning is good for in their teaching. Four qualitatively different ways of conceiving of eLearning were discovered: (a) to provide information to students; (b) for occasional communication among unit participants; (c) to engage students in online discussions; and (d) to support knowledge-building tasks. Four dimensions of variation provided a more detailed picture. These were: role of teacher, role of students, unit participants' interaction and perception of embeddedness with face-to-face component. Results are situated in line with those from previous research and indicate an emerging consensus of findings. Academic developers may benefit from these outcomes by using them in designing eLearning support programs. Further studies confirming or challenging previous findings, as well as associating conceptions of eLearning and teaching, are proposed.
