    Playing in the Classroom: A Game Proposal for the Flipped Classroom
    (IEEE, 2020) Vélez, B.; Verdugo, G.; Mejía-Pesántez, M.; Veintimilla-Reyes, J.; Maldonado Mahauad, Jorge Javier
    Today, gamification is a topic that is taking hold in the educational context. Institutions of Higher Education (IES) have maintained the master class as a traditional teaching method, where the teacher is the center of the learning process and his main function is to transmit information within the classroom. However, thanks to technology, didactic technological tools are currently being included to transform learning spaces and reduce low rates of academic performance. IES have begun to configure new hybrid learning environments, where they seek to incorporate gamification to motivate and keep students engaged during their learning inside and outside the classroom. The objective of this work is to present a game proposal that will be adapted in the context of a flipped class. For this, a board game is proposed that will include gamification elements, where it will seek to promote student motivation and observe the impact produced on their learning. Finally, the result was useful theoretical foundations that allow to promote the use of gamification in hybrid learning environments, to later develop an efficient and effective gamified application that helps increase student motivation.

    Spinning cone column isolation of rosemary essential oil
    (ELSEVIER SCI LTD, 2010) Graber, M. F.; Perez Correa, J. R.; Verdugo, G.; Del Valle, J. M.; Agosin, E.
    Chemical compositions of rosemary (Rosmarinus officinalis L.) essential oil isolated using different processes, steam distillation and a spinning cone column (SCC), and harvested at different times, spring and autumn, were compared. The effect SCC operating parameters had on yields was also studied. The method used for isolating the oil influenced its composition and yield. The main components found were: camphor, beta-myrcene and 1,8-cineole. SCC derived oils were more consistent and richer, on average, in oxygenated Compounds than steam distilled oils. Furthermore, citronellol, chrysanthenone, piperitone and thymol were detected in SCC oils but not in their steam distilled counterparts. SCC yields were more consistent at a 1/40 dilution while higher yields were achieved at the same dilution spinning at 570 rpm, (C) 2009 Elsevier Ltd. All rights reserved.
