Ibn Battuta essays

Ibn Battuta essays Ibn Battuta was one of the great travelers of ancient history. He traveled to Mecca on his first hajj to complete the service that all Muslims should do if they are able to. Traveling to Mecca was an adventurous experience and many people didn't make it because the trip was very rough on the body. There were rituals that had to be followed before Ibn Battuta got to Mecca and rituals that had to performed while in Mecca. These rituals sometimes symbolized events of the past. Before reaching Mecca, Ibn Battuta went through several different places such as North Africa, Egypt, Palestine, and Syra. "There were five stations on the trails leading to Mecca where pilgrims were required to enter into the state of consecration called ihram." At this point the male pilgrims prayed and washed themselves. After they finished praying they received a special garmet, also called an ihram. The garmet they received was two plain white cloths; one was wrapped around the waist and the other was wrapped around the top portion of the body, but didn't cover one shoulder. The ihram symbolized equality of all men before God, the pilgrim was to behave himself the same as he entered. In October 1326, Ibn Battuta finally reached Mecca and he went to the Holy House. Pilgrims from all over gathered in Mecca to pray in the Sacred Mosque. When a visitor arrives in Mecca, he must as his very first act perform the tawaf, the cirumambulation. He walks around the Ka'ba seven times counterclockwise slowly, while reciting prayers special to the occasion. Each time he passes the eastern corner he kisses or touches the Black Stone, he does this because the Prophet kissed the stone. Once the pilgrim has completed his tawaf he goes to the Maqam where he prays a prayer of two prostrations. Next the pilgrims go to the well to drink, the water is sacred and has a saline taste, but the pilgrims still drink it because it heals them. After drinking from the ...

Understanding the Visible Learning Theory

Understanding the Visible Learning Theory Educators struggle with a number of questions regarding teaching methods, including: What educational policies have the greatest impact on students?What influences students to achieve?What are best practices for teachers yield the best results? Roughly 78 billion is the estimated dollar amount invested in education by the United States according to market analysts (2014). So, understanding how well this enormous investment in education is working requires a new kind of calculation in order to answer these questions. Developing that new kind of calculation is where Australian educator and researcher John Hattie has focused his research. In his inaugural lecture at the University of Auckland as far back as 1999, Hattie  announced the three principles that would guide his research: We need to make relative statements about what impacts on student work;We need estimates of magnitude as well as statistical significance – it is not good enough to say that this works because lots of people use it etc., but that this works because of the magnitude of impact;We need to be building a model based on these relative magnitudes of effects. The model he proposed in that lecture has grown to become a ranking system of influencers and their effects in education using meta-analyses, or groups of studies, in education. The meta-analyses he used came from all over the globe, and his method in developing the ranking system was first explained with the publication of his book Visible Learning in 2009. Hattie noted that the title of his book was selected to help teachers become evaluators of their own teaching† with the objective of giving teachers a better understanding of the positive or negative effects on student learning: Visible Teaching and Learning occurs when teachers see learning through the eyes of students and help them become their own teachers. The Method Hattie used the data from multiple meta-analyses in order to get a pooled estimate or measure of an effect on student learning. For example, he used sets of meta-analyses on the effect of vocabulary programs on student learning as well as  sets of meta-analyses on the effect of preterm birth weight on student learning. Hatties system of gathering data from multiple educational studies and reducing that data into pooled estimates allowed him to rate the different influences on student learning according to their effects in the same manner, whether they show negative  effects or positive effects. For example, Hattie ranked studies that showed the effects of classroom discussions, problem-solving, and acceleration as well as studies that showed the impact of retention, television, and summer vacation on student learning. In order to categorize these effects  by  groups, Hattie organized the influences into six areas: The studentThe homeThe schoolThe curriculaThe teacherTeaching and learning approaches Aggregating the data that was generated from these meta-analyses, Hattie determined the size of the effect each influence had on student learning. The size effect could be numerically converted for purposes of comparison, for example, an influencer’s effect size of 0 shows that the influence has no effect on student achievement. The greater the size of the effect, the greater the influence. In the 2009 edition of Visible Learning,  Hattie suggested that an effect size of 0,2 could be relatively small, while an effect size of 0,6 could be large. It was the effect size of 0,4, a numerical conversion that Hattie termed as his â€Å"hinge point,† that became the effect size average. In the 2015  Ã‚  Visible Learning,  Hattie rated influence effects by increasing the number of meta-analyses from 800 to 1200. He repeated the method of ranking influencers using the â€Å"hinge point† measurement which allowed him to rank the effects of 195 influences on a scale. T he Visible Learning website has several interactive graphics to illustrate these influences. Top Influencers The number one influencer at the top of the 2015 study is an effect labeled â€Å"teacher estimates of achievement. This category, new to the ranking list, has been given a ranking value of 1,62, calculated at four times the effect of the average influencer. This rating reflects the accuracy of an individual teachers knowledge of students in his or her classes and how that knowledge determines the kinds of classroom activities and materials as well as the difficulty of the tasks assigned. A teacher’s estimates of achievement can also influence  the questioning strategies and the student groupings used in class as well as the teaching strategies selected. It is, however, the number two influencer, collective teacher efficacy, that holds an even greater promise for improving student achievement.  This influencer means harnessing the power of the group to bring out the full potential of students and educators in schools.   It should be noted that Hattie is not the first to point out the importance of collective teacher efficacy. He is the one who rated it as having an effect ranking of 1.57, almost four times the average influence. Back in 2000, educational researchers Goddard, Hoy, and Hoy advanced this idea, stating that â€Å"collective teacher efficacy shapes the normative environment of schools† and that the â€Å"perceptions of teachers in a school that the efforts of the faculty as a whole will have a positive effect on students.† In short, they found that â€Å"teachers in[ this] school can get through to the most difficult students.† Rather than rely on the individual teacher, collective teacher efficacy is a factor that can be manipulated at a whole school level. Researcher Michael Fullen and Andy Hargreaves in their article Leaning Forward: Bringing the Profession Back In  note several factors that must be present including: Teacher autonomy to take on the specific leadership roles with opportunities to participate in making decisions on school-wide issuesTeachers are allowed to collaboratively develop and communicate mutual goals that are clear and specificTeachers are committed to the goalsTeachers work as a team transparently without judgmentTeachers work as a team to collect specific evidence to determine growthLeadership acts responsively to all stakeholders and show concern and respect for their staff. When these factors are present, one of the outcomes is that collective teacher efficacy helps all teachers understand their significant impact on student results. There is also the benefit of stopping teachers from using other factors (e.g. home life, socio-economic status, motivation) as an excuse for low achievement. Way at the other end of the Hattie ranking spectrum, the bottom, the influencer of depression is given an effect score of -,42. Sharing space at the bottom of the  Visible Learning  Ladder are the influencers mobility (-,34) home corporal punishment (-,33), television (-,18), and retention (-,17). Summer vacation, a much-beloved institution, is also negatively ranked at -,02. Conclusion In concluding his inaugural address almost twenty years ago, Hattie pledged to use the best statistical modeling, as well as to conduct meta-analyses to achieve integration, perspective, and magnitude of effects. For teachers, he pledged to provide evidence that determined the differences between experienced and expert teachers as well as to assess the teaching methods that increase the probability of impact on student learning. Two editions of Visible Learning are the product of the pledges Hattie made in determining what works in education. His research can help teachers see better how their students learn best. His work is also a guide for how to best invest in education; a review of 195 influencers that can be better targeted by  statistical significance  for billions in investment...78 billion to start.

Logistics and operation managment - Essay Example In this context, it must be mentioned that some of the most important activities of operations and logistics management in the present day scenario includes inventory management, capacity management, and delivery and scheduling among others (Harrison & et. al., 2014). All these factors and their efficacy determine success or failure for the overall operations and logistics management of any business unit (Mahadevan, 2010). Operation management is one of the most vital processes that are involved within the operations of any particular business. It include managing the overall operations of the business in a most efficient manner with due adherence to the goals and objectives of a business. In order to have a practical understanding of this particular aspect, a study of capacity and inventory management along with forecasting and scheduling has been conducted as part of a production simulation exercise. A team of few members conducted the exercise. The name of the team was Legendary. In order to determine the effectiveness of the teamwork, it will be vital to discuss about the weaknesses and strengths of the methods and approaches used to complete the process of operations management based on a given scenario. The group i.e. legendary primarily targeted on using a simplistic scheduling approach in completing the entire process. In this regard, it has been seen that the team intended to reduce as well as control the cost of inventory. This particular approach is deemed to be quite vital for controlling the cost of the overall operation management project. This approach or strategy of inventory management has its own strengths and weaknesses. Following this approach, the team i.e. legendary has been able to control and reduce the cost of inventory management of the company provided within the given scenario. This was done with the help of proper and accurate scheduling of stocks
