<p>Interaction is crucial to student satisfaction in online courses. Adding synchronous components (virtual classroom technologies) to online courses can facilitate interaction. In this study, interaction within a synchronous virtual classroom was investigated by surveying 21 graduate students in an instructional technology program in the southeastern United States. The students were asked about learner-learner, learner-instructor, learner-content, and learner-interface interactions. During an interview, the instructor was asked about strategies to promote these different forms of interaction. In addition, the academic, social, and technical aspects of interactions were examined in three course archives using Schullo’s (2005) schema. Participants reported that the Wimba interface was easy to use and that various features, such as text chat and the webcam, facilitated interaction among the students and with the instructor in the virtual classroom. The importance of students’ ability to receive immediate feedback and their experience as presenters was highlighted across the various kinds of interaction. The instructor’s teaching style and visual presence were instrumental in engaging students with the content. The results suggest that student interaction, and hence learning, was aided by the live communication that occurred through the virtual classroom. This study has implications for those who are considering adopting virtual classroom technologies for their online or blended teaching.</p>

This contribution sets out, through the analysis of the teaching styles, the texts and graphic material of the six chapters about Mechanics of the handbook Physique Chimie (Collection AREX, Les classiques africains) of the first years of high school science classes, to highlight the difficulties and obstacles that the teacher or the student face in using it.. The results of the analysis from the epistemological and didactic benchmarks knowledge to teach the mechanics show that the manual emphasizes the use of more informative teaching style and that of the illustrative figures to state the knowledge to be taught. Thus, the approaches used do not refer to a real problematization and do not allow students to be independent and productive; they are not actively and intellectually engage students in the learning process. Faced with the passivity of the student in the acquisition of knowledge, it thus seems necessary to include in the training of the teacher, a teacher training course based on understanding of texts and teaching styles to support a constructivist pedagogy class.

Background: Deliberate practice is an important method of skill acquisition and is under-utilized in dermatology training. We delivered a dermatologic morphology training module with immediate feedback for first year medical students. Our goal was to determine whether there are differences in accuracy and learning efficiency between self-regulated and algorithm-regulated groups. Methods: First year medical students at the University of Calgary completed a dermatologic morphology module. We randomly assigned them to either a self-regulated arm (students removed cases from the practice pool at their discretion) or an algorithm-regulated arm (an algorithm determined when a case would be removed). We then administered a pre-survey, pre-test, post-test, and post-survey. Data collected included mean diagnostic accuracy of the practice sessions and tests, and the time spent practicing. The surveys assessed demographic data and student satisfaction. Results: Students in the algorithm-regulated arm completed more cases than the self-regulated arm (52.9 vs. 29.3, p<0.001) and spent twice as much time completing the module than the self-regulated participants (34.3 vs. 17.0 min., p<0.001). Mean scores were equivalent between the algorithm- and self-regulated groups for the pre-test (63% vs. 66%, n = 54) and post-test (90% vs. 86%, n = 10), respectively. Both arms demonstrated statistically significant improvement in the post-test. Conclusion: Both the self-regulated and algorithm-regulated arms improved at post-test. Students spent significantly less time practicing in the self-directed arm, suggesting it was more efficient.

AI is a multidisciplinary activity that involves specialists from several fields, and we can say that the aim of science, and AI science, is solving problems. AI and computer sciences are been creating a new kind of making science, that we can call in silico science. Both models top-eown and bottomup are useful for e-scientific research. There is no a real controversy between them. Besides, the extended mind model of human cognition, involves human-machine interactions. Huge amount of data requires new ways to make and organize scientific practices: supercomputers, grids, distributed computing, specific software and middleware and, basically, more efficient and visual ways to interact with information. This is one of the key points to understand contemporary relationships between humans and machines: usability of scientific data.

Intructional model in Physical Education becomes an important part to achieve the success of learning objectives at every level of education. Physical Education intructional  model consists of various models that can be applied by the teacher. The intructional  model carried out will affect a student mastery, including in passing technique learning in volleyball that has not got maximum results. Physical Education teachers implement several learning modifications, from teaching style to the use of supporting media for passing learning. The purpose of this study was to determine the most suitable intructional  model for the under passing technique mastery in volleyball. The literature review technique was employed by collecting literatures from google scholar, science direct, and research gate websites. The search keyword was passing intructional  model in volleyball or volleyball teaching models. The review method was chosen to find a solution related to the most appropriate volleyball intructional  model for passing technique from the findings of previous research. Fourteen national journals and 1 international journal were selected based on volleyball passing learning model keyword on google scholar and had been reviewed. The results showed that there are various learning methods applied in volleyball passing learning, including practical learning models with various movement drills, pair practice, cooperative learning, game learning, jigsaw, discovery learning, peer teaching, command learning, and use of walls as media. This study concludes that, in the volleyball passing mastery, there are various models that can be applied. It recommends that further research studies the most suitable practical learning models to be applied at the Elementary School, Junior High School, and Senior High School levels.

Objective: The objective of the study was to perform in silico molecular docking and in vitro anticancer studies of proposed 1,2,4-triazole derivatives for the determination of their anticancer activity. Methods: A series of 10 triazole compounds with different substituents were drawn in ACD Lab ChemSketch software. Molecular and biological properties were identified using Molinspiration software. The compounds that obeyed Lipinski rule of five are subjected for pharmacokinetic parameters prediction and docking analysis. SwissDock ADME software is used for the prediction of absorption, distribution, metabolism, and elimination. Then, the compounds are docked with target enzymes in Chimera software 1.14 version. The molecular docking studies revealed favorable molecular interactions and binding energies. The compounds that showed good docking results were synthesized through wet lab synthesis and further preceded for in vitro anticancer studies. Results: Three compounds are selected for wet lab synthesis due to their good docking results compared to other compounds. The synthesized compounds are subjected to different in vitro anticancer studies and found to be having potential anticancer activity. Conclusion: The pharmacokinetic and docking studies conclude that the triazole compounds have potential as anticancer agents. The in vitro anticancer studies revealed that the triazole derivatives are having high potency of anticancer activity against pancreatic cell lines.
