ScLi-8 Identify the structure оf pаrаgrаphs in intrоductiоns of research papers The following statements are [1] A study reported that changing to workshop (or studio) models of instruction, which emphasize collaborative group work in class, cut failure rates by 40–60% in introductory physics across a range of institutions. Researchers found that the use of peer instruction with clickers reduced the drop rate in introductory physics at a community college and at a research university by factors of two to three. A study which implemented reading quizzes, in-class active-learning activities and weekly practice exams, showed that the failure rates in an introductory biology course for majors, was lower compared with low-structure course designs that are based on lecturing and a few high-risk assessments. To produce a simple paragraph we would need [2] The following would be an adequate statement to be included in the paragraph [3] (modified from Eddy, S.L. and Hogan, K.A., 2014. Getting under the hood: How and for whom does increasing course structure work?. CBE—Life Sciences Education, 13(3), pp.453-468. and Freeman, S., Haak, D. and Wenderoth, M.P., 2011.

ScLi5- Identify the purpоse оf intrоduction in scientific pаpers The following pаrаgraphs belong to the introduction of A comparative examination of odontogenic gene expression in both toothed and toothless amniotes. In this study, Dr. Lainoff (professor in our Bio department) and colleagues investigated the genetic underpinnings of the lack of teeth in turtles. "Two key problems at the intersection of evolutionary and developmental biology are how complex organs such as teeth are formed and how variable morphology is generated. One method for identifying unknown components of complex genetic pathways is to investigate examples in nature where development has been disrupted. Despite the strong selective pressure on teeth, several vertebrates have lost their dentitions during evolution, including birds, baleen whales, anteaters, several lineages of fish, and turtles. Discrepancies in genetic pathways or in developmental timing between toothed taxa and toothless taxa can be used as tools for identifying aberrant changes linked to tooth agenesis. [...] Studies conducted in mouse models suggest that the position where teeth will develop is established by the interactions of two mutually antagonistic signaling molecules, FGF8 and BMP4 (Neubüser et al., 1997). Early in development, the oral epithelium of the mouse mandible is broadly divided into two domains: Fgf8 and Fgf9 mark the proximal (lateral) region, defining the presumptive molar field, while Bmp4 marks the distal (mesial) area, delineating the presumptive incisor field (Åberg et al., 1997; Kettunen and Thesleff, 1998). [...] In this study, we first investigate potential mechanisms underlying the loss of teeth in turtles during evolution by examining the red-eared slider turtle, Trachemys scripta elegans, for histological and molecular evidence of tooth development. Additionally, we take a preliminary step towards addressing whether the antagonistic initiation of tooth development by BMP4 and FGF8 is conserved across amniotes, as well as whether limited Bmp4 expression is a good indicator of subsequent tooth loss, by determining whether Bmp4, Msx1, Msx2, and Fgf8 expression is conserved in an edentate reptile (T. scripta), a toothed reptile (the American alligator, Alligator mississippiensis), and a toothed non-placental mammal (the gray short-tailed opossum, Monodelphis domestica) during developmental stages equivalent to embryonic stage 10.5 (E10.5) in mice."
