In normal times, the network ties that connect students on a college campus are an asset; during a pandemic, they can become a liability. Using pre-pandemic data from Cornell University, Weeden and Cornwell showed how co-enrollment in classes creates a “small world” network with high clustering, short path lengths, and multiple independent pathways connecting students. In this paper, we show how the structure of the enrollment network changed as Cornell, like many American colleges and universities, shifted to a hybrid instructional model with some courses online and others in person. Under this model, about half of students are disconnected from the in-person co-enrollment network. In this network, paths lengthened, the share of student pairs connected by three or fewer degrees of separation declined, and clustering increased, with a greater share of ties occurring between students in the same field. The small world became both less connected and more fragmented. (Corrected page proofs. Paper is forthcoming in Sociological Science.)

Abstract. By means of two studies, a self-report measure to assess self-efficacy in presentation and moderation skills, the SEPM scales, was validated. In study 1, factorial and construct validity were examined. A sample of 744 university students (41% females; more than 50% between 20 and 25 years) completed newly constructed self-efficacy items. Confirmatory factor analyses (CFAs) substantiated two positively correlated factors, presentation (SEPM-P) and moderation self-efficacy (SEPM-M). Each factor consists of eight items. The correlation patterns between the two SEPM subscales and related constructs such as extraversion, the preference for cooperative learning, and conflict management indicated adequate construct validity. In study 2, criterion validity was determined by means of latent change modeling. One hundred sixty students ( Mage = 24.40, SD = 4.04; 61% females) took part in a university course to foster key competences and completed the SEPM scales at the beginning and the end of the semester. Presentation and moderation self-efficacy increased significantly over time of which the latter was positively associated with the performance in a practical moderation exam. Across both studies, reliability of the scales was high, ranging from McDonald’s ω .80 to .88.

География это мировоззренческая наука. Сложившаяся за десятилетия структура курса обучения географии в российской средней школе знакома каждому из нас и состоит из четырёх этапов. В университете система обучения будущих учителей географии состоит из тех же самых этапов, однако, это не просто углублённое повторение школьной программы, это совершенно новый, более высокий уровень географического образования. Как на школьном, так и на университетском уровнях изменения происходят в масштабе тем и разделов отдельных этапов, но этапы остаются неизменными. Межэтапный уровень является предельным, его осознание не попадает в область рефлексии педагогов и методистов. Отсутствуют и научные труды по его анализу. В качестве метода исследования выступает диалектика, законы которой срабатывают в виде мировоззренческих формул. В школьном географическом образовании проблема формирования восприятия не проявляется чётко и поэтому не осознаётся. Проблемы начинают проявляться на межэтапном уровне. Мировоззренческая формула дихотомии перестала работать в виде противопоставления отраслевая география районная география, взаимодействие в этой бинарной оппозиции строилось по принципу отраслевой анализ региональный синтез. В разделах районной географии исчезли механизмы (энергопроизводственные циклы) и формы синтеза (природнотерриториальные и территориальнопроизводственные комплексы). Произошла утрата целесообразности изучения районной географии. Новых форм синтеза в постсоветское время на вооружение российской школьной и университетской географией принято не было. В университетском курсе, который был направлен на осознание диалектических знаний школьного курса и развитие их, невозможно провести рефлексию, так как основы географических знаний у абитуриентов бесформенные. Владение мировоззренческими формулами это вопрос отражения географической реальности. В переходе с уровня на уровень возрастает самостоятельность географического мышления и удаление от стереотипов, возрастает эвристический потенциал за счёт сочетания формул, которое даёт вариативность отражения географической реальности. Geography is a worldview science. The structure of the geography course in the Russian secondary school, which has developed over the decades, is familiar to each of us and consists of four stages. At the University, the system of teaching future teachers of geography consists of the same stages, however, it is not just an indepth repetition of the school curriculum, it is a completely new, higher level of geographical education. At both the school and University levels, changes occur in the scale of topics and sections of individual stages, but the stages remain the same. The interstage level is the limit, its awareness does not fall into the field of reflection of teachers and methodologists. There are no scientific papers on its analysis. The method of research is dialectics, the laws of which work in the form of worldview formulas. In school geographic education, the problem of perception formation is not clearly manifested and therefore is not realized. Problems begin to emerge at the interstage level. The worldview formula of dichotomy ceased to work in the form of the opposition sectoral geography regional geography, the interaction in this binary opposition was based on the principle of sectoral analysis regional synthesis. Mechanisms (energy production cycles) and forms of synthesis (naturalterritorial and territorialproduction complexes) have disappeared in the sections of the district geography. There was a loss of expediency of studying of regional geography. New forms of synthesis in the postSoviet period were not adopted by the Russian school and University geography. In the University course, which was aimed at understanding the dialectical knowledge of the school course and their development, it is impossible to reflect, as the basis of geographical knowledge of students formless. The possession of ideological formulas is the question of geographic reality. In the transition from level to level increases the independence of geographical thinking and the distance from stereotypes, heuristic potential increases due to the combination of formulas, which gives variability of reflection of geographical reality.
