Originally PowerPoint was developed for commercial and business purposes by Microsoft before approximately 20 years.However it has speedily penetrated the scientific and educational circles as well (Szabo & Hastings 2000 176). Microsoft estimates that 1. 25 million PowerPoint presentations take entrust every hour (Levasseur & Sawyer 2006 101). In the traditional education environments, the duty of the students is to adhere the education activities as a passive bumpr and memorize the content of the lesson (Surmeli 2007 30). PowerPoint presentations create more powerful sensory alerts when compared with the traditional education materials (blackboard, overhead projections, etc. While giving the lessons with PowerPoint presentations, the content of the lesson stays the alike(p), but the form of transmittal the lesson to the student changes. The PowerPoint presentations which are prepared for lessons have the advantages such as having strong colors, gradual bui lding of text, open animation of diagrams, facilities for simple editing and updating (Lowry 199919). Thus it can be mentioned that the PowerPoint presentations provide significant time and force savings. As the popularity of the PowerPoint presentations increase, the studies concerning the pedagogical results of the usage of this tool increase.The advantages of giving lessons with the PowerPoint presentations could be generalized as follows in the light of the academic studies till now * PowerPoint contributes to properly forming the course content and giving lesson (Sugahara & Boland 2006 392, Hlynka & stonemason 1998 47, Nouri & Shahid 2005 55). * It simplifies fetching notes during the lesson (Cook 1998 5, James et al 2006 386) * Students think that following the lesson from the screen is funny and interesting, so the PowerPoint presentations positively affect students (Parks 1999 207, Nouri adenylic acid Shahid 2005 58, James vd 2006 391, Atkins-Sayre et al 2006). * PowerPoi nt motivates the students for attendance to the lessons (James vd 2006 387, Sugahara & Boland 2006 396). * PowerPoint encourages students for encyclopedism (Harrison 2006 10. Despite these advantages brought about by technology, lock in there are some teachers who are resistant to change their styles in teaching. They keep on applying the traditional method of teaching like the use of manila paper, lecture discussions and so on.The researcher believes that there is a great impact on the academic achievement of the learners by victimization this form of multimedia although there has been a lack of consensus in the studies concerning the effect of PowerPoint presentations on the student performance. Till now, the researches about this progeny reached different results. Somehow, the researcher hopes to encourage the Science teachers to put some innovations in their practice by present the Effect of PowerPoint presentations in the Academic Achievement of the Senior Students of Madap dap Rest.High School in Physics. STATEMENT OF THE PROBLEM This action research aimed to situate the Effect of PowerPoint presentations in the Academic Achievement of the Senior Students of Madapdap Rest. High School in Physics. Specifically, it purports to answer the following questions 1. Which between the two groups perform remedy? 2. Was there a significant difference in the use of PowerPoint presentations and the traditional method of teaching? Hypotheses 1. Group A (traditional method of teaching) perform founder than group B(PowerPoint presentation) 2.There is no significant difference in the use of PowerPoint presentation and the traditional method of teaching. Scope and Delimitation This action research on The Effect of PowerPoint Presentations in the Academic Achievement of the Senior Students of Madapdap Rest. High School in Physics was conducted at Madapdap Rest. High School located in Madapdap Rest. Mabalacat Pampanga. There were two hundred (200) senior high school students who were chosen respondents of this depicted object. LITERATURE REVIEWThe Relation of Dual Coding speculation and PowerPoint The theoretical framework of the effect of education technology tools, which have high visual personal effects like PowerPoint, on canvas is Dual Coding speculation generated by Allan Paivio in 1986. Dual Coding Theory is based on the assumption that the same training coding (presenting) in two different but supporting each former(a) forms heightens efficiency in learning. Paivio began his studies concerning Dual Coding Theory in learning process in 1960s and the theory was developed in 1986.After 1980s, the significance of the theory was increased by the development of education technology practices (Aldag & Sezgin 2003 125). Paivios Dual Coding Theory could theoretically explain the effect of PowerPoint in learning when it is thought with the information coding theory. According to the information coding theory, the process of learning is a s follows (Tay 2004 3) * Information is received from external sources by senses * It transforms into specific forms by electing in sensory biography * It is coded in petty-term store The information in the abundant term memory goes back to the short term memory and integrates with the new information, becomes coded with this method and has a new meaning * The coded information storages in the long term memory. According to the several researches concerning Dual Coding Theory, individuals learn more effectively with the combination of verbal and visual information (Levasseur & Sawyer 2006 105).Presentation of information to the students by education technologies that evokes the non-verbal systems such as PowerPoint presentations, contributes to the process of transmission the information to short term memory from sensory registers and then to long term memory later coding them. Through the usage of PowerPoint, during the lessons, the words or the concepts that should be emphas ized could be also visually presented and the attractiveness of the information increases. A study by Luna and McKenzie (2001) indicates that both faculty and students think multimedia presentations enhance learning.However, test results showed no difference between multimedia and traditional lecture formats. In contrary, the study make by M. Gale Blalock and Robert D. Montgomery (2005) on The Effect Of Powerpoint On Student Performance In Principles Of EconomicsAn preliminary Study shows that the results indicate that multimedia presentations can improve test scores significantly. Additionally, students who are above-average academic performers receive more benefit from multimedia presentations than students of below-average academic performance.One study that has examined the family between multimedia and student learning and attitudes was conducted by Butler and Mautz (2003). In a laboratory experiment conducted during a 30-minute time period, they found that multimedia did not affect student remembrance in all situations. vButler and Mautz did find an interaction between the effects of the multimedia presentation and the students preferred class representation style (i. e. , whether the student was considered a verbal or imaginal learner). Effect of PowerPoint presentations on student learning.The evidence that PowerPoint presentations turn learning is largely anecdotal. Bryantand Hunton (2000)states that the power point of improved learning is a function of a complex set of interactions among learner and medium attributes. Mason and Hlynka (2001) state that PowerPoint helps structure the content and processing of a lesson or lecture. Aiding note-taking (and thus facilitating study) is another purported advantage of using PowerPoint (Cook, 1998). Parks (2005) report that students liked the lecture outline and graphs on the screen, and that the PowerPoint presentation had a positive influence on students.Harrison (2006) argues that PowerPoint enhances instruction and motivates students to learn. If this is true, the bigger question is, does PowerPoint help students learn? PowerPoint presentations incorporate graphics, animation, and color (imagery). Human information processing theories focus on how the human memory system gathers, transforms, compacts, elaborates, encodes, reclaims, and uses information. Sensory registers, short-term memory, and long-term memory are the three major storage structures of the human brain.Research has shown that attention plays an important role in find out when and how information is further processed from sensory registers to short and long-term memory. If information is not attended to, it is quickly lost in the sensory stimulus stage of processing. Reynolds and Baker (2000) find that presenting materials on a computer increased attention and learning, and learning increased as attention increased. Human information processing theories can shed light on how PowerPoint features (graphics, anim ations, etc. ) may influence learning.Information encoded at a representational aim generates a short term memory trace, while information encoded at the referential level elicits both referentially-related verbal and nonverbal memory traces of a longer term nature. Associatively encoded information results in memory traces that include information about multiple verbal or Nonverbal items (Paivio 1990). It is referential encoding that is most applicable for this study. The graphical nature of the PowerPoint presentation arouses students imagery systems, which become more activated when information (e. . , instructional materials) is presented in non-verbal forms. PowerPoint presentations should arouse the imagery system and could contribute to comprehension, and improve short and long-term memory. Since, in a PowerPoint presentation, topics are presented in a hierarchical fashion with graphics, color, and animation, students could use a mental image of that outline to study, to re trieve the information on a test, to organize their answer for an essay question, and to perform other educational tasks (Clark and Paivio, 1991. p. 176). ruddiness (2001) also notes that presentation of learning materials in graphical form is beneficial for students. Interaction between Learners preferent Representation Styles and PowerPoint Presentation Cognitive theory suggests that learning is optimized when learners preferred representation styles are congruent with the attributes of educational technology. While offering guidelines for educators in using technology for instruction, Bryant and Hunton (2000) suggest that individual characteristics (cognitive differences) be taken into circular in instructional design.Dual coding theory suggests that learners have preferred representation styles. Some individuals learn and recall well from visually presented information while others learn and recall well from verbally presented information. Kozma (1994) submits that to underst and the relationship between media and learning, we need to consider the interaction between the attributes of the medium and the cognitive processes of students. METHODOLOGYThis study attempted to determine the Effect of PowerPoint Presentations in the Academic Achievement of the Senior Students of Madapdap Rest. High School in Physics. This action research was experimental in nature. The researcher selected among the 4th year students of Madapdap Rest. High School via draw lottery and were chosen as the respondents of this study. The respondents were divided into Group A and B and used as control and experimental groups respectively.The presentation for group A (control group) was support by traditional, text-based, black-and-white, visual aids while the presentations for Group B (experimental group) was supported by PowerPoint, which provided colorful visual aids with graphics and animation. Two different teachers were used for this research study with the use of the same modules in Physics. Table 1. shows the summary of the modules including the lessons and the time frame that was utilized in this study. Table 1.

Teacher A used traditional method of teaching in presenting his lessons while Teacher B utilized PowerPoint presentations in demonstrating his unit of operating instructions. At the end of the 1st quarter, the respondents were evaluated their academic performance based on the modules presented. Each group was given identical tests on the same date in the form of standardized test from the Division Office made by supervisor. This test was parallel with the modules that were presented as stated in the course description.Students performance was measured based on their examination scores. After administering the test, the scores were tabulated, analyzed and interpreted. The researcher computed the mean and proficiency level of the students to assess which one performs better in the standardized test and to determine the significant difference of the two groups, t-test was applied for independent samples. Results and Discussions Table 2. shows the mean, proficiency level and the standard deviation of the students under the supervision of Teacher A who used the traditional method of instruction.

Importance of International Finance

International Financial Management is unique primarily beca substance abuse the firm must luck in more than than its own up-to-dateness. 2 A multinational is a corporation that has operations in more than one untaught. 3 It is also called an International Corporation. It ordinarily consists of 1 parent company and about 6 unusual subsidiaries, typically with a high degree of strategic intervention between them. E. G. The Coca Cola order is a multinational company, selling in more than 200 countries and having net sales of $7169 million in the 1st quarter of 2009. 4 Financial advantages of foreign operations An overseas foodstuff provides a larger market and thus, a potential increase in the sales of the firms products. For some corporations, it might mean a set in production costs if their opening a subsidiary in a country that offers dirt cheap labor, raw materials or machinery. Also, instead of only exporting goods to other nations, once an NC starts operations in another( prenominal) country, the risk of detrimental laws restricting the sales of their products as well as an increase in the valuate on their products, decreases substantially.Exchange rates and their effects An exchange rate is the expression of the value of one notes in terms of another amounts currency. 5 There are two ways of expressing this value 1. Direct quotation domesticated Currency / Foreign Currency 2. Indirect quotation Foreign Currency/ Domestic currency The two methods are different ways of expressing the same thing. Throughout the project, ERE is quoted in direct quotation. Banks in most countries use a system of Foreign Exchange Market and its Fluctuations The volume of international transactions has grown considerably in the past 50-70 years.Trade and investment of this magnitude would be impossible without the ability to buy and sell currencies. The latter(prenominal) must be done for one currency is not the acceptable means of payment in all countries engaged in great deal. The foreign exchange market is one of the largest in the world which facilitates the acquire and selling of currencies, whose price is determined by the ERE. The market is over-the- counter, I. E. Trade is carried out using computer terminals, telephones, telecoms devices and agile an international banking communications network that electronically links brokers and traders.It is not confined to any one country but is dispersed by dint ofout the leading financial centers of the world. Participants The major participants are large commercial banks that trade with one another, channeling most currency transactions through the worldwide interbrain market. Their transactions are conducted through foreign exchange brokers, who specialize in matching net supplier and demander banks. The brokers charge a brokerage house fee and in return, offer anonymity to both parties and minimize the contact of banks with other traders.Small banks and local offices of major banks have lines of credit with large banks or with the home office. Customers deal with the bank, which then makes use of the line of credit. former(a) players are brokers, international money centre banks, central banks of many countries, portfolio managers, foreign exchange brokers, hedgers, traders and speculators. Another thespian in the market is the arbitrageur, who seeks to earn risk-free profit by taking advantage of difference in interest rates between countries and make use of forward contracts to eliminate ERE risk.If the value of home currency A decreases relative to the value of currency B, A is a weakening or depreciating currency and B is a strengthening or appreciating currency. ERE quoted indirectly will fall. For the importers of country A, ore of their home currency is call for to purchase goods of country B. The vice versa is true for country B. Therefore, the attractiveness of a countrys goods and services abroad is Judged by the relative values of the currencies of the importing and exporting countries. Types of Transactions 1 .

Attendance and Participation Reflection - Essay ExampleThis paper leave look at my reflection on the attendance of cloud computing classes.I began attending the classes with an go of advancing my understanding of computing and internetworking of computers in order to advance my understanding of the interconnectivity of the computers in a network. I had not imagined of using the interconnection aspect to ease the work at my fathers business. However, when I realized the need to improve the mode of operation of the business through cloud computing, I became more and more interested in the course and devoted much of my time in learning what really this new aspect in the field of computing really mean and how I could apply this noesis to improve and expand the business. The course made me realize that I can actually use totally one computer as my main server and connect several other computers (commonly referred to as the girlfriend computers) to it in order to share information f rom a single pool. These other daughter computers (sister stations) can thusly be linked to one another and the corresponding software be used at the same time by several other users (multiple user aspect) (Jansen and Grace, 2011).Upon the realization of how easy computers can make sustenance so cheap and efficient, I tried so much to invest much of my time in learning the basics of interconnectivity so that I could do this back at the business site. The topic on Reliable and Secure it services which was taught in the middle of the course actually evoked more my admiration concerning how banks operate in sharing their services in different regions without actually doing it through the internet as I thought before. The topic was examining how reliable and secure such a network can be as compared to the other types of networking such as the global networking processes enabled by the companies such as Google and Microsoft. I and then realized I can help my father expand his busine ss in various regions and reminder the operations and remittance of the
