Pedagogical Practices Essay Abstract This paper provides an insight on the effective pedagogical practices that can be used in the children learning. Some of these practices include the incorporation of ICT in early childhood education and some of effective direct instructional strategies that can have an impact in the learning process of children. Five common learning outcomes for children are identified. In addition, the paper outlines characteristics of effective teaching that contribute to effective teaching. Furthermore, the concept of culture in early childhood education is also discussed. Keywords: Effective teaching, Pedagogy Introduction Early childhood education in Australia falls under the responsibility of each state. The approach in each State towards early childhood education is different. The different States have different school starting ages, nomenclature, approaches in the testing and evaluation of the children, policies, support services and both public and private funded childhood education and care programmes. In Australia, children in preschool and childcare are usually placed under the funding and policy of the health sector, whereas those children aged between 5 and 8 years are placed under the school sector. Amendments by the government have resulted to the combination of the health sector provision and childcare policy to the education sector. Childcare in the States of Victoria has been moved to the Department of Human Services to the Department of Early Childhood Education (DEEW, 2009). In Australia, pedagogy and learning have been put within the context of a developmental paradigm that is widely influenced by developmental (Sumsion et al., 2009). In the past, the school segment has been involved in implementing a discipline-focused criterion together with the child-centred approach to learning and pedagogy. The childcare sector mostly concerns itself with the child, whereas the school sector mainly focuses on the implementation of the curriculum (Church, et al., 2010). Some of the efforts by the Australian government in promoting preschool education include the investing of a million dollars in to the research and development of innovative practices in childcare and preschools. In addition, additional funds have been directed towards the development and research of early childhood programmes. Furthermore, the Australian government is developing a nationwide curriculum for early childhood development that will be implemented nationwide (DEECD, 2009). Pedagogy refers to the correct use of teaching strategies. In addition, pedagogical practices are those set of principles that facilitate and support effective teaching. Use of pedagogy standards assists in the teachers and childhood professionals in achieving their goals (Fleet, Patterson Robertson, 2006). According to the Victorian Framework, five outcomes for children can be identified. These include identity, sense of community, communication, learning and well-being (VCAA, 2000). Effective Teaching Effective teaching is dependent on certain outcomes. These outcomes include the whether the students learn something as the result. Despite the introduction of teaching strategies that have been described as effective, use of these strategies will produce different outcomes in the different learning situations (City et al., 2009). In these scenarios, the teacher will be confronted with the idea of developing instructional strategies and behaviours, which are effective practices as well as combining these strategies at the appropriate time to the individual students. In addition, the teacher has to apply of these strategies depending on the different learning situations and what is the teacher’s goal for students learning outcome (City et al., 2009). Effective teaching’s primary purpose is the attainment of academic knowledge of the student. In addition, effective teaching, as a whole encompasses the attainment of skill or knowledge on a subject of interest by a student, students feeling good about themselves, students obeying the society laws and students liking the school (Alter Coggshall, 2009). Besides ensuring increased academic achievement, the use of instructional strategies should not produce affective loss. Moreover, the instructional strategy that produces positive affective results is the most effective teaching strategy. In order to achieve effective teaching fully, vital understanding of the effective teaching practices, the students, teaching contexts, coherent decision making and learning environments is significant (Dahlberg, Moss Pence, 1999). Characteristics of Effective Teaching Effective teaching involves effective communicating, planning, managing and evaluating the actual process of instructing. Reflective teaching plays a major role in making of informed decision relating to the effective teaching strategies (Mabrina, Church Tayler, 2010). Through reflective teaching, teachers can be able to do a critical analysis their actions and their decisions. Reflective teaching allows teachers to foresee the impact of the teaching methods and in the process may make relevant changes in improving their strategies. In addition, the teacher gains a deeper understanding by scrutinizing the goals of the teaching practice. According to the DEECD (2009), children’s learning becomes advanced when they experience interactions with highly effective childhood professionals. Application of reflective teaching allows the childhood teachers to promote practices are supported by evidence to be doing well in supporting and developing children learning (Osterman, 1990). Furthermore, reflective teaching will allow the childhood professionals ability to challenge and develop new practices that they discover to be effective. In the process of reflective teaching the childhood professionals, improve their knowledge and skills concerning early childhood education. Teachers have to have a comprehensive understanding of the learning values of development the children to cater for the variety of and diversity of children in a classroom setting (Ashmna and Elkins, 2009). This allows the teacher to select the best effective teaching strategies. Consequently, this will necessitate the need of the use of a various instructional resources and technology. To be effective teachers must have adequate knowledge on the subject, which they propose to teach. This includes professional knowledge about teaching in general, pedagogical knowledge about the concepts and theories of effective teaching and pedagogical content knowledge concerning the different teaching approa ches and methods. Another important t characteristic of effective teaching involves the use of a variety of teaching strategies. Use of a variety of teaching techniques stimulates the student s during lesson activities and may encourage students to participate actively in the lesson. This especially true when dealing with children who are normally intrigued by different things and hence in the process may enjoy the lessons. The advantage is that children have inquisitive minds and anything new to them encourage exploratory mind (Rinaldi, 2006). Furthermore, proper assigning of tasks taking into account the time factor will provide the children with adequate time for learning new ideas. Various ways can be used to increase children engagement in learning activities. The teacher can monitor the work of the children as the progress and make comments and appreciation of their efforts. In addition, preparation of a daily schedule that gives a description of the activities that the children will undertake will assist in reducing time wastage activities such as giving directions. Furthermore, individual assignments given to the child should be interesting and easy to them as well as different to what the other children are doing. This promotes their confidence in being able to carry out activities on their own. The children should not only be involved in just doing things in class as a way of ensuring children success rate. The activities should be meaningful and have a relation to what the teacher is planning on teaching. Planning of these activities should replicate the capability and interests of the children. If a child is successful in one day, chances are that the child will replicate the same success in the days to follow. Effective Pedagogical Practices Cognitive Construction Cognitive structures refer to the patterns of the mental or physical actions that bring about specific acts of acumen. These are conditioned by stages of development. An assumption using the Piaget theory is that children are natural and active developers of their own understanding. Growth in a child results to the integration of abstract structures in their understanding. Using Piaget theories on child development, the teacher can be able to facilitate developmental change in a child by assisting the child to find contradictions using hid or prior knowledge and understanding. Culturally Relevant Pedagogy The Victorian Framework for early childhood development t recognizes the fact that culture plays a significant t role in the shaping the learning and development outcomes of children. The childhood professional use of culture empowers the children both socially and emotionally. An example of how the Victorian Framework incorporates culture-based pedagogy is in the Aboriginal culture. Respecting and learning the value of this culture will assist in ensuring that the Victorian children have a sense of belonging in the community. Culture, in this case, is used as a vehicle for learning. Moreover, incorporating of children’s books that outlines the different cultures will assist the children in developing their own personal identities related to their different cultures. In addition, the children can be able to understand the relationships that exist between Australia and Asia and in the process grow up understanding the Asian culture. (ACARA, 2010) Creating Relationships Fostering relationships among the children will assist in building trust, understanding thereby creating a peaceful learning environment for the children. The children strengths’ can be increased by encouraging the children to talk about the family histories. Incorporation of this strategy will assist the children develop social and persona competence as they learn to mange and understand their relationships. This is a key aspect of the Australian Curriculum, Assessment, and Reporting Authority (2010). Furthermore, the children will be able to start friendship relationship with one another, work effectively as a team, and be able to make responsible decisions (ACARA, 2010). Use of Technology In recent times, the use of computer games and simulations has a possibility of improving how children learn. Early childhood professionals can incorporate an assortment of strategies using technology. These include the use of a learner-centred approach, promoting cognitive activity, and focusing on learning outcomes. A learner-centred approach will help in assisting the natural process through which children learn. In addition, this approach will allow a better understanding of the children’s cognitive processing and, therefore, affect the learning outcomes of the child. In focusing on promoting the cognitive activity, video games cause the children to be more active. This allows teachers to recognize how the different aspects of the computer software affect the learning process of the child. Consequently, measuring the learning outcomes of the games can help in accessing the level of comprehension in a child. In addition, use of reading software can help determine what children learn from the use of the software. Use of ICT is a key component in the Australian curriculum (ACARA, 2010). Direct Instruction Hunt and Touzel (2009) suggest that the use of direct instruction strategies allows teachers to be able to organize and present material to the children. Direct instructional strategies are characterized by a certain level of predictability of the children responses. This allows teachers to be to respond with ease and in the process save time. The teacher best applies direct teaching for children in the learning of procedures and skills. Teachers use the direct instructional strategies to present information through which the children use their prior knowledge and give feedback to the teacher. Direct instruction strategies ensure the close monitoring of the children’s outcomes and ensure effective use of classroom organization and management methods. The direct instruction process consists of modelling, direct practice, guided practice and independent practice. In modelling, the skill to be imparted on children is performed by the teacher. This normally involves thinking aloud so that the children can grasp the concept. In direct practice, the teacher uses questions through a variety of steps that allow the children to understand the reason behind every step, whereas, in guide practice, the children generate questions working through various steps while the teacher observes, guides them, and provides a response to the questions. Lastly, in independent practice, the students have gained the ability to work on their own and can be able to do more questions without much assistance from the teacher. Examples of direct instructional strategies include explicit teaching, drill, demonstration, lecture presentation and teacher led guide discussion. However, lecture presentations are not effective in teaching children. In explicit teaching, the teacher first gain the attention of the children then provides information, which the children can use to provide feedback to the teacher. Use of demonstrations in teaching children is a more effective method the use of direct instruction. In demonstrations, the children can observe how the teacher carries out a certain task, which helps to increase the attention of the children. Furthermore, using demonstrations allow the children to look at the actual activity rather than hearing about something they cannot see. An example of a demonstration that is normally used in teaching children is the teacher showing them how to tie their laces. Most of these demonstrations are explanatory in nature (Moss et al., 2006). References ACARA (2010). The Shape of the Australian Curriculum.

Censorship and Selection Essay -- self-censorship

Introduction Censorship is a dirty word to information professionals. Attempts by individuals or groups to restrict the public from reading, hearing or viewing certain materials due to their content, is enough to send librarian's and organizations such as the American Library Association, to the proverbial battle field. However, information professionals from all fields have to make choices about what to include and what not to include in their particular library's collection. How are these selections made? What causes one item to be selected instead of another? The distinction between censorship and selection is infinitesimal, dependent mainly upon the role of the individuals involved. As an information professional, who inherently is charged with the responsibility to protect the rights of the public to have free access to materials, much care must be taken in the selection of materials. By evaluating the collections, by carefully examining what deeply held beliefs we have, and by carefully a dhering to selection policies, information professionals can guard against allowing personal bias influencing selection decisions. What Is Censorship? Censorship can take many forms, but it inherently leads to an individual or group attempting to restrict access to materials. Jenkinson (2002) defines a censor as someone who â€Å"begins with a list of negatives or 'no-no's' and then seeks to identify whether any of these 'taboo' words, subjects, themes or attitudes are present in an item† (p. 22). Irregardless of the context, a censor then seeks to either have the item removed, or not acquired at all. (Jenkinson, 2002, p. 22). Censorship can take place in a visible manner, such as a parent or group challenging a book. However, a far more... ... Hill, R. (2010). The problem of self-censorship. School Library Journal.

Identify What Is Happening in the External Environment in Terms

There are three external factors that affect business: Political, Legal and Social. Political factors involve political stability, government support, taxation and direct support. Legal factor involves things such as employment laws, consumer laws, it also influence attitudes such as healthy eating. Social factor involves education, age, ethics, attitudes etc. Political factors An activity related to government policy and its administrative practices that can have an effect on something.Most business operators will keep a watchful eye on any political factor, such as new legislation or regulatory shifts, which could have a substantial impact on how their company operates and its bottom line. Political decisions involve making choices that affect large number of people and business. Government support for different types of organization- government supports different organizations in different ways. There are three types of organizations- private, public and nonprofit/voluntary.In pri vate sector, government tries to create an environment where business can compete. In the nonprofit/voluntary sector, government support business by giving various grants and tax reliefs. In the public sector the government covers the losses made by government owned organizations. Governments use taxation to encourage or discourage certain economic decisions. For example, reduction in taxable personal (or household) income by the amount paid as interest on home mortgage loans results in greater construction activity, and generates more jobs.Government also puts high taxes, for example they put high taxes on cigarettes and alcohol to discourage smoking and drinking, and high taxes on fuel to reduce pollution by discouraging people of driving cars so much. Government also tries enhancing the skills of the population. They enhance education and training help to increase skills of working population. They provide a range of training and creates the educational framework including differ ent types of qualifications, such as Apprenticeships and NVQs. Legal factors Business must operate within the framework of the law.There are three laws that affect business: Company law- how business set up and run, Contract law- contracts that business make with suppliers, employees and etc, and Competition law- how business are allowed to compare with each other. The Contract Law is a set of rules governing the relationship, content and validity of an agreement between two or more persons regarding the sale of goods, provision of services or exchange of interests or ownership. The reason for this is due to the big number of examples in which contracts can arise in everyday life.Contract law is law that governs oral and written agreements associated with exchange of goods and services, money, and properties. It includes consumer protection and employment law. Consumer protection involves: †¢Sales of Goods Act, this act means that the retailers have to sell goods as they are de scribed and satisfactory quality. It means that marketing should describe the product accurately. These laws are aimed at safeguarding consumers by ensuring that goods offered for sale are reasonably safe, and meet certain standards of quality to make them fit for their intended use. The consumer credit act this applies to business who sells goods on credit, or companies that lend money. Business need to be licensed by the Office of Fair Trading. This act wants business to give their customers updates on their account regularly. If the customer falls behind the repayments the FOS may extend the time for the customer to repay their debt. †¢Employment law means that employees are also protected at work. The contract of employment should include names of both parties, job title and description, hours of work, wages etc. Social factorsAre factors that influence individuals' personality, attitudes and lifestyle. Demographic issues, when a population of a country is growing, there is an increase in goods and services and people available to work. Changes in structure means aging population. When the number of older people increase fast the demand for some goods increase, for example wheel chairs, anti-aging creams, world cruises etc. Household and families, there are increasing number of single-person households in the uk. The average marriage age is increasing aswell and many people now live alone.Education- the level of education is very important nowadays. In almost all industries employers are expecting employees to have a good information about technology, and have good skills at the job they’re doing. Attitudes to work influence relationships between employers and employees. Britain has developed a long working hour’s culture compared to France and Italy. How external factors affect McDonalds in the UK and Lithuania McDonald’s is the world largest chain of fast food restaurants with more than 30000 restaurants serving 52 million custo mers in more than 100 countries each day.McDonald’s primarily sells hamburgers, cheeseburgers, chicken products, french-fries, breakfast items, soft drinks, milkshakes and desserts. More recently, it has begun to offer salads, wraps and fruit. Each McDonald’s restaurant is operated by franchise, an affiliate, or the corporation itself. The corporation revenues come from the rent, royalties and fees paid by the franchisees, as well as sales in company-operated restaurants. McDonald’s revenues grew 27% over the three years ending in 2007 to $22. 8 billion, and 9% growth in operating income to $ 3. billion. Within the UK there are approximately 1200 restaurants employing over 85,000 people. In Lithuania there are just 9 restaurants employing less than 200 people. Political factors In the UK McDonald's main competitors are Chippy Shops, Subway and KFC. McDonalds always needed to treat competitors carefully. That's way the factor related with competitor like competit ors product quality, service, price competition, market, sales, growth everything impacting McDonalds. In Lithuania the only competitor for McDonalds is Hesburger.There are not many fast food restaurants so there is not much competition going on. In both countries employees are impacting McDonalds because company is recruiting, training staff for company. It is not uncommon for McDonalds to be the employer of first resort for young people just entering the workforce, older workers desiring extra income, or for those planning on transferring from one corporation to another. So, employee is impacting McDonalds in this way. Legal factors In both counties McDonalds producing their product and they are serving those directly to customers.That's way the factor of product and service is impacting McDonalds. Product quality, product variety, quick and friendly service, every things are important for company. Those got an important impact on McDonalds. Employment law also affects McDonalds i n the UK and Lithuania. In the UK minim wage is: Apprentice- ? 2. 65, under 18- ? 3. 68, 18 to 20- ? 4. 98 , and over 21- ? 6. 19. In Lithuania, there are not hourly wages, but the minimum salary for everyone in Lithuania is 232 euro a month.People in England has more money to spend on fast food restaurants than Lithuanians due to a larger income, therefore McDonald restaurants make much bigger profits in the UK than in Lithuania. Social factors In the UK there are many more McDonald’s restaurants than in Lithuania, mainly because of people’s Lithuanian people are more keen on healthy eating than British people. Most of Lithuanian people grow their own vegetables and fruit; they also like to buy organic foods from the market, and stays away from fast food restaurants. McDonalds are not so popular in Lithuania as it is in the UK because of different coulture.
