Between Secularist and Jihadist Bodes, Egypt and Sudan in Crossroads
European Scientific Journal September 2016 edition vol.12, No.26 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431 Between Secularist and Jihadist Bodes, Egypt and Sudan in Crossroads Mahgoub El-Tigani Mahmoud Tennessee State University doi: 10.19044/esj.2016.v12n26p21 URL:http://dx.doi.org/10.19044/esj.2016.v12n26p21 Abstract The societal conflicts between Secularist groups and Jihadist militants on the role religious orientations played in the state democratization, social justice, human rights, and population development posited national exigencies un-decisively met by governments of the African and Arab regions. Part one of our research theorized three typologies shaping the challenges of similar conflicts in the Arab-African states of Egypt and Sudan. The typologies symbolized a Sufi culture perpetuating Muslims’ humanitarian relations; Secularist thought excluding the politics of faith; and Jihadist reactionaries manipulating symbolic representation of religion in the striving for power domains. Lacking in serenity the Sufi culture maintained for ages by popular prevalence, the Jihadist reactionaries sponsored a theocratic militancy that generated instability by excessive violence. Entrenched in non-democratic authoritative systems, the state failed in both countries to end peacefully the deepened tensions of the ongoing contradictions. Preserving the popular culture and supporting democratic governance, the Sufi/Secularist groups would probably continue to resist the theocratic dogma that evidently penetrated the region.

It is based on the spacing and the testing effects. In recent reviews, spacing and retrieving practices have been highly recommended as there is ample evidence of their long-term retention benefits, even in educational contexts (Dunlosky, Rawson, Marsh, Nathan & Willingham, 2013). An experiment in a real secondary education classroom was conducted in order to show spaced retrieval practice effects in retention and student’s motivation. Results confirm the evidence, spaced retrieval practice showed higher long-term retention (26 days since first study session) of English vocabulary words compared to massed practice. Also, student’s motivation remained high at the end of the experiment. There is enough evidence to suggest educational institutions should promote the use of spaced retrieval practice in classrooms. RESUMEN La recuperación espaciada es una técnica de aprendizaje que se lleva estudiando desde hace muchos años (Ebbinghaus, 1885/1913; Gates, 1917) y que al mismo tiempo ha permanecido como una gran olvidada en los sistemas educativos. Se basa en los efectos que producen el repaso espaciado y el uso de test. En recientes revisiones de la literatura se promueve encarecidamente el uso de estas prácticas, ya que aumentan la retención de recuerdos en la memoria a largo plazo, incluso en contextos educativos (Dunlosky, Rawson, Marsh, Nathan & Willingham, 2013). -
The Spaced Interval Repetition Technique
The Spaced Interval Repetition Technique What is it? The Spaced Interval Repetition (SIR) technique is a memorization technique largely developed in the 1960’s and is a phenomenal way of learning information very efficiently that almost nobody knows about. It is based on the landmark research in memory conducted by famous psychologist, Hermann Ebbinghaus in the late 19th century. Ebbinghaus discovered that when we learn new information, we actually forget it very quickly (within a matter of minutes and hours) and the more time that passes, the more likely we are to forget it (unless it is presented to us again). This is why “cramming” for the test does not allow you to learn/remember everything for the test (and why you don’t remember any of it a week later). SIR software, notably first developed by Piotr A. Woźniak is available to help you learn information like a superhero and even retain it for the rest of your life. The SIR technique can be applied to any kind of learning, but arguably works best when learning discrete pieces of information like dates, definitions, vocabulary, formulas, etc. Why does it work? Memory is a fickle creature. For most people, to really learn something, we need to rehearse it several times; this is how information gets from short‐term memory to long‐ term memory. Research tells us that the best time to rehearse something (like those formulas for your statistics class) is right before you are about to forget it. Obviously, it is very difficult for us to know when we are about to forget an important piece of information. -

Designing and Evaluating Feedback Schemes for Improving Data Visualization Performance 1
Designing and Evaluating Feedback Schemes for Improving Data Visualization Performance A Major Qualifying Project Report Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE In partial fulfillment of the requirements for the Degree of Bachelor of Science By Meixintong Zha Submitted to Professor Lane T. Harrison Worcester Polytechnic Institute 2 Abstract Over the past decades, data visualization assessment has proven many hypotheses while changing its platform from lab experiment to online crowdsourced studies. Yet, few if any of these studies include visualization feedback participants’ performance which is a missed opportunity to measure the effects of feedback in data visualization assessment. We gathered feedback mechanics from educational platforms, video games, and fitness applications and summarized some design principles for feedback: inviting, repeatability, coherence, and data driven. We replicated one of Cleveland and McGill’s graph perception studies where participants were asked to find the percentage of the smaller area compared to the larger area. We built a website that provided two versions of possible summary pages - with feedback (experimental group) or no feedback (control group). We assigned participants to either the feedback version or the no feedback version based on their session ID. There were a maximum of 20 sets of twenty questions. Participants needed to complete a minimum of 2 sets, and then could decide to either quit the study or continue practicing data visualization questions. Our results from -
Learning Efficiency Correlates of Using Supermemo with Specially Crafted Flashcards in Medical Scholarship
Learning efficiency correlates of using SuperMemo with specially crafted Flashcards in medical scholarship. Authors: Jacopo Michettoni, Alexis Pujo, Daniel Nadolny, Raj Thimmiah. Abstract Computer-assisted learning has been growing in popularity in higher education and in the research literature. A subset of these novel approaches to learning claim that predictive algorithms called Spaced Repetition can significantly improve retention rates of studied knowledge while minimizing the time investment required for learning. SuperMemo is a brand of commercial software and the editor of the SuperMemo spaced repetition algorithm. Medical scholarship is well known for requiring students to acquire large amounts of information in a short span of time. Anatomy, in particular, relies heavily on rote memorization. Using the SuperMemo web platform1 we are creating a non-randomized trial, inviting medical students completing an anatomy course to take part. Usage of SuperMemo as well as a performance test will be measured and compared with a concurrent control group who will not be provided with the SuperMemo Software. Hypotheses A) Increased average grade for memorization-intensive examinations If spaced repetition positively affects average retrievability and stability of memory over the term of one to four months, then consistent2 users should obtain better grades than their peers on memorization-intensive examination material. B) Grades increase with consistency There is a negative relationship between variability of daily usage of SRS and grades. 1 https://www.supermemo.com/ 2 Defined in Criteria for inclusion: SuperMemo group. C) Increased stability of memory in the long-term If spaced repetition positively affects knowledge stability, consistent users should have more durable recall even after reviews of learned material have ceased. -

Weinstein et al. Cognitive Research: Principles and Implications (2018) 3:2 Cognitive Research: Principles DOI 10.1186/s41235-017-0087-y and Implications TUTORIALREVIEW Open Access Teaching the science of learning Yana Weinstein1* , Christopher R. Madan2,3 and Megan A. Sumeracki4 Abstract The science of learning has made a considerable contribution to our understanding of effective teaching and learning strategies. However, few instructors outside of the field are privy to this research. In this tutorial review, we focus on six specific cognitive strategies that have received robust support from decades of research: spaced practice, interleaving, retrieval practice, elaboration, concrete examples, and dual coding. We describe the basic research behind each strategy and relevant applied research, present examples of existing and suggested implementation, and make recommendations for further research that would broaden the reach of these strategies.
