A common example of the modality principle is the visual presentation of a diagram accompanied by commentaries as an effective case. The presentation of the diagram alongside the text creates a split-attention effect. Extraneous processing overload occurs when the tutorial possesses attention getting extraneous aspects or when the class is delivered in a puzzling manner. Extraneous processing is cognitive in nature and is brought about by the teaching material that lacks proper instructional objectives and does not entail any learning process. The major effects of excessive extran eous processing include fundamental attribution errors. A just-in-time (JIT) model contributes toward a decrease in extraneous cognitive loads as the temporal split attention is averted. Limiting the temporal split of attention in teaching by JIT information presentation will also decrease the extraneous cognitive load. Similar to incorporating graphics and words, information separated is then integrated resulting in a lesser extraneous burden because the students need not to â€Å"search-and-match† and intellectually put together the information given. Mayer performed several experiments that illustrated the temporal split attention effect (Mayer, 2009). JIT learning solutions have the objective of solving issues within education when they happen. When JIT is applied, it lets loose the cognitive ability for grasping the unique aspects of a multifaceted cognitive skill and therefore, improves the transfer process. Strategies to Reduce Extraneous Processing The removal of coherence aids is an efficient method of reducing and even eliminating extraneous processing. The instructor can remove any extraneous images, words or sounds that may distract or confuse the learner. Although the instructor may want to make the lesson interesting by using background music or other elements, students need all these extraneous material removed as it fills their retention and working memory with irrelevant items. A typical example would be to remove screeching sounds from a class on vehicle braking (Mayer, 2009). Signaling principles dictate that people learn easily when what is important is highlighted. The instructor can also include signals that stress the important parts of the lesson. This can be done by highlighting significant images or sounds and leaving the others intact. The instructor can also insert cues that direct the learner toward crucial material (Plass et al, 2010). Lastly, the redundancy issue within extraneous processing can also be solved by removing any redundant items within the lesson. Redundancy has the same effect as inconsistency in that it gives the learner more material to process in their brains. These three strategies will ensure that extraneous processing is lowered (Koning et al, 2010). There are certain areas that have presented instances of extraneous processing within this course. Most of the examples and illustrations that I have encountered in websites on this topic have a lot of redundant material. They all contained a specific set of information that was repeated in diagrams and side notes. Analyzing the content of one website was tiring and effective. The textbooks also issued several illustrations that were not necessary for my study.

The Annapolis Convention of 1786

The Annapolis Convention of 1786 The Annapolis Convention was an early American national political convention held at Manns Tavern in Annapolis, Maryland, on September 11- 14, 1786. Attended by twelve delegates from the five states of New Jersey, New York, Pennsylvania, Delaware, and Virginia, the convention was called to address and remove the self-serving protectionist trade barriers each state had independently established. With the United States government still operating under the state power-heavy Articles of Confederation, each state was largely autonomous, with the central government lacking any authority to regulate trade between and among the various states. While the states of New Hampshire, Massachusetts, Rhode Island, and North Carolina had appointed delegates to the Annapolis Convention, the failed to arrive in time to participate. The other four of the 13 original states, Connecticut, Maryland, South Carolina, and Georgia, refused or chose not to take part. Though it was comparatively small and failed to accomplish its intended purpose, the Annapolis Convention was a major step leading to the creation of the U.S. Constitution and the current federal government system. The Reason for the Annapolis Convention After the end of the Revolutionary War in 1783, the leaders of the new American nation took on the daunting job of creating a government capable of fairly and efficiently meeting what they knew would be an ever-growing list of public needs and demands. America’s first attempt at a constitution, the Articles of Confederation, ratified in 1781, created a rather weak central government, leaving most powers to the states. This resulted in a series of localized tax rebellions, economic depressions, and problems with trade and commerce that the central government was unable to resolve, such as: In 1786, a dispute over alleged economic injustices and suspension of civil rights by the state of Massachusetts resulted in Shays Rebellion, an often violent dispute in which protestors were eventually subdued by a privately raised and funded militia.  In 1785, Maryland and Virginia engaged in a particularly nasty dispute over which state should be allowed to profit from the commercial use of the rivers that crossed both states. Under the Articles of Confederation, each state was free to enact and enforce its own laws regarding trade, leaving the federal government powerless to deal with trade disputes between different states or to regulate interstate commerce. Realizing that a more comprehensive approach to the powers of the central government was needed, the Virginia legislature, at the suggestion of future fourth President of the United States James Madison, called for a meeting of delegates from all of the existing thirteen states in September 1786, in Annapolis, Maryland. The Annapolis Convention Setting Officially called as a Meeting of Commissioners to Remedy Defects of the Federal Government, the Annapolis Convention was held September 1114, 1786 at Manns Tavern in Annapolis, Maryland. A total of only 12 delegates from just five states- New Jersey, New York, Pennsylvania, Delaware, and Virginia – actually attended the convention. New Hampshire, Massachusetts, Rhode Island, and North Carolina had appointed commissioners who failed to arrive in Annapolis in time to attend, while Connecticut, Maryland, South Carolina, and Georgia chose not to participate at all. Delegates who attended the Annapolis Convention included: From New York: Egbert Benson and Alexander HamiltonFrom New Jersey: Abraham Clark, William Houston, and James SchuremanFrom Pennsylvania: Tench CoxeFrom Delaware: George Read, John Dickinson, and Richard BassettFrom Virginia: Edmund Randolph, James Madison, and St. George Tucker The Results of the Annapolis Convention On September 14, 1786, the 12 delegates attending the Annapolis Convention unanimously approved a resolution recommending that Congress convene a broader constitutional convention to be held the following May in Philadelphia for the purpose of amending the weak Articles of Confederation to rectify a number of serious defects. The resolution expressed the delegates’ hope that the constitutional convention would be attended by representatives of more states and that the delegates would be authorized to examine areas of concern broader than simply laws regulating of commercial trade between the states. The resolution, which was submitted to Congress and the state legislatures, expressed the delegates’ deep concern regarding â€Å"important defects in the system of the Federal Government,† which they warned, â€Å"may be found greater and more numerous than even these acts imply.† With only five of the thirteen states represented, the authority of the Annapolis Convention was limited. As a result, other than recommending the calling of a full constitutional convention, the delegates attending the delegates took no action on the issues that had brought them together. â€Å"That the express terms of the powers of your Commissioners supposing a deputation from all the States, and having for object the Trade and Commerce of the United States, Your Commissioners did not conceive it advisable to proceed on the business of their mission, under the Circumstances of so partial and defective a representation,† stated the convention’s resolution. The events of the Annapolis Convention also prompted eventual first President of the United States George Washington to add his plea for a stronger federal government. In a letter to fellow Founding Father James Madison dated November 5, 1786, Washington memorably wrote, â€Å"The consequences of a lax, or inefficient government, are too obvious to be dwelt on. Thirteen Sovereignties pulling against each other and all tugging the federal head, will soon bring ruin on the whole.† While the Annapolis Convention failed to accomplish its purpose, the delegates’ recommendations were adopted by the U.S. Congress. Eight months later, on May 25, 1787, the Philadelphia Convention convened and succeeded in creating the present U.S. Constitution.
