Instant messaging for enquiry-based learning and peer learning communities
Get PDFInstant Messaging (IM) tools such as Telegram may effectively be used to engage students in their learning. This paper explored how IM can enhance traditional teaching and learning in higher education by creating additional informal learning spaces, rather to disturb the existing classroom practices. There are three objectives that this paper was expected to achieve:- • To measure the student Response rate in using IM for the assessment of effectiveness in enquiry-based learning; • To evaluate the impact of IM on peer-to-peer participation through the analysis of dialogues among the learning communities; and • To discuss the essentials of successful application of IM in informal learning spaces. A module named Highway Engineering (CON4381) of Higher Diploma in Civil Engineering at the Hong Kong Institute of Vocational Education was selected with a large class size of over 300 students. The results were encouraging with over 100 students participated in the learning communities and more than 200 number of questions posed and interaction counts. The activities trends and students’ feedbacks showed positive perception and acceptance of the use of Telegram for teaching and learning. A questionnaire designed by the authors was used at the end of the semester and the participants showed positive perception and acceptance of the use of Telegram for teaching and learning. It was revealed that IM tools could elicit new learning opportunities, foster enquiry-based learning, offer informal and formal learning opportunities, and support peer learning community. A valuable discussion was conducted to address challenges in adopting IM as transmission pedagogy including merging of academic and non-academic contents, perceived distractive nature and potential to trigger off-task behaviours and sometimes limited participation of all students etc. Although such challenges exist in adopting IM as pedagogy, the potential to foster an effective learning environment should not be underestimated. Together with the widespread participation of all students and enhanced willingness on public expression of silenced voices, the utilization of instant messaging was found to be reasonably valid. Furthermore, an investigation into a mobile app which supplemented Vocational Training Council\u27s Moodle learning management platform was made so as to explore further usability whenever appropriate
Overexpression of Cd36_03760 in Candida dubliniensis abrogates development of biofilms
No full textObjectives: To investigate the in vitro effects of overexpression of Cd36_03760 on the development of biofilms in Candida dubliniensis Methods: C. dubliniensis strains that overexpress Cd36_03760 were constructed using a PCR-based gene targeting method. Overexpression was verified by real time quantitative PCR (RT-qPCR) using gene-specific primers upon addition of doxycycline. C. dubliniensis biofilms were prepared in polystyrene, flat bottom 96-well microtiter plates. The cell suspension (1 mL, 107cells/mL in PBS) was transferred to the wells and incubated at 37oC, 75 rpm for 90 min. After the removal of loosely adherent cells, fresh YPD (1 mL) with doxycycline (50 µg/mL) was added to the wells and incubated for 48 h for biofilm formation. The amount of protein in the extracellular matrix of the C. dubliniensis biofilms was determined using a BCA protein assay. The development of biofilms was qualitatively assessed by scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM). Results: BCA protein assay indicated that the amount of protein in C. dubliniensis biofilms that overexpressed Cd36_03760 was reduced by ~35% (P \u3c 0.05) compared to its control. The SEM and CLSM results confirmed that overexpression of Cd36_03760 in C. dubliniensis abrogated the biofilm architecture: the biofilms were scanty, less dense, and less organised compared to its control which was relatively confluent. Conclusions: Cd36_03760 is a gene that is involved in biofilm development in C. dubliniensis. Overexpression of Cd36_03760 in C. dubliniensis disintegrates the biofilms. It sheds light on further development of novel antifungal interventions against this emerging human fungal pathogen by selectively inhibiting the activity of enzymes that are involved in biofilm development
