Transformational Learning Essay - 1027 Words

Transformational Learning Transformational learning is a philosophy of change. It identifies people why change is necessary, what benefits will be accrued by changing, how to change, and most importantly, how to incorporate and embrace change in education. The study of transformational learning emerged with the work of Jack Mezirow (1981, 1994, 1997). Transformational learning is defined as learning that induces more far-reaching change in the learner than other kinds of learning, especially learning experiences which shape the learner and produce a significant impact, or paradigm shift, which affects the learners subsequent experiences (Clark, 1993). Numerous authors have published papers on various aspects of†¦show more content†¦Meaning perspectives naturally change and evolve in response to life experiences, especially those which induce powerful emotional responses in the individual. Often these life-changing events are personal crises such as divorce, death of a loved one, natural or man-made disasters and accidents, health crisis, financial upheaval, or unexpected job changes. It is these meaning perspectives which Mezirow saw as the raw material of the changes that occur in transformational learning. Mezirow (1997) further states that we do not make transformative changes in the way we learn as long as the new material fits comfortably in our existing frames of reference. Three common themes characterized Mezirows theory of the mechanism of transformational learning in the classroom. These were experience, critical reflection, and rational discourse. The students life experiences provided a starting point for transformational learning (Mezirow, 1991). Mezirow considered critical reflection to be the distinguishing characteristic of adult learning, and saw it as the vehicle by which one questions the validity of his world-view. He identified rational discourse as a catalyst for transformation, as it induced the various participants to explore the depth and meaning of th eir various world-views, and articulate those ideas to their instructor and class mates. Mezirow (1997) emphasizes that transformative learning is rooted in the way human beings communicate, and does not link itShow MoreRelatedTransformative Learning : Transformational Learning1585 Words   |  7 PagesJoseph Cardello May 13, 2015 Learning paper Draft Dr. Franklin Tuner Kean University Transformative learning overview Thinking is something we all do on a regular basis.

An Analysis of Harriet Byrd From The Natural Essay example

In movies there is always a villain or bad guy to ruin someone’s life or career. The only reason why they go after that person is because of jealously, money, or hatred. It is not always easy for villains or temptresses to get their targets, so they have to come up with clever ideas to lure their victims in. In the movie The Natural Harriet Byrd’s killing spree started off as jealously towards people who are very experienced in what they do and only want fame and fortune from it. When Harriet sees how much potential Roy Hobbs has in playing baseball, she then tries figures out what he wants from his extraordinary talent making him her next victim due to his answer. Evidence that exemplifies Harriet as the seducer is when she first†¦show more content†¦Some characteristics that prove Harriet as a dark person is when she is always in dimmed to dark lighting, and never showing all of her face. Harriet’s whole persona is edgy and unusual, so for a first impression she should make you quite aware what kind of person she is and leave you with your guard up. Another scene that shows Harriet’s seductive ways is when she and Roy are talking in the dining car on the train. Harriet first approaches him late one night when she sees Roy sitting alone, and the train is going through a dark tunnel which causes the car to become dark with dim flickering lights. She then invites herself to joining him at his table, and starts asking questions focused on him. One question that Harriet asked was â€Å"what do you want from being a baseball player† and when Roy replied â€Å"to be the best there ever was and will be† she was not satisfied with his answer and asked confused â€Å"is that it?† finally trying to settle with his answer. From that point on we start to realize how Harriet is having mixed feelings with Roy when they are about to kiss, but a second later when there lips are about to touch she disappears into the dark. An example that gives an even deeper look into Harriet’s archetypal character is when Roy is finally at his hotel. A mysterious thing Harriet did was when she called Roy’s room and then told him to come up to her room. But since Roy didn’t see anything wrong with that at the time he went on up to her room without a second

Leadership Bob Shallenberger and John Cavanagh

Bob and John are exercising leadership in various ways. First of all, they have a vision for their organisation and they have exchanged this purpose with their people. Employees are aware that the company wants to be recognised as the top green builder in the country so they will contribute towards this shared vision.Advertising We will write a custom coursework sample on Leadership: Bob Shallenberger and John Cavanagh specifically for you for only $16.05 $11/page Learn More Also, leadership can be seen through the fact that Shallenberger and Cavanagh have energized their people. They are passionate about their business and have passed on this energy to others in the organisation. This is an action that all leaders have to engage in. Furthermore, leadership has been exercised through the act of working with people well to produce remarkable results at the end. It appears as though they are actually partnering with their employees rather than merely givin g them orders on what to do or how to go about it (Dubrin, 2010). As they attract cool people to work with them, these two entrepreneurs are exercising the role of persuasion. In other words, they have managed to illustrate to the applicants that the company has the potential to provide them with the most conducive workplace environment. It seems as though the would-be employees have seen the supportive environment that they are likely to find here than elsewhere. Also, the leadership role of guiding could be another important factor. If already existing employees are treated with mutual respect rather than being ordered around then they are likely to stick to the company and maybe even spread the word that the firm is a great place to work. This would cause even more cool people to be attracted to it because they would be rest assured that there are going to find what they are really looking for (Dubrin, 2010). Cool people are likely to be keep working for Highland Homes because th e owners are passionate about what they do. Instead of merely taking a businesslike and boring approach to everything, Shallenberger and Cavanagh believe in doing everything passionately. This inclination is going to rub off on everyone else as the latter will not just be thinking of their workplaces as just any other job.Advertising Looking for coursework on business economics?

For instance, they have the stereo, CD player etc that are typical in all their homes. Cool people are likely to want to work for people who continuously look for creative ways of doing business. Also, as opposed to being highly bossy, the employees of Highland Homes are going to stay on because they will find that their employers are very inspiring. They will be motivated to keep reaching their potential and this will definitely keep them there (Dubrin, 2010). In order to be the top green residential builder in the US, Shallenberger and Cavanagh may need to cultivate great interpersonal skills within themselves so as to maintain a close association with the team working for them. This will cause them to possess joint accountability and decision making ability. A case in point was Roadway management which spread leadership to lower levels. This ensured that everyone played a part in the success of the firm and eventually contributed towards the realisation of huge profits. Essentially, what this implies is that once responsibilities are shared then the likelihood of attaining common goals is going to increase. They must motivate their people to want to work harder so that Highland Homes can outsmart or outdo their competitors. People who are driven by passion rather than rules are likely to put in more and their results would speak for themselves (Dubrin, 2010). Reference Dubrin, A. J. (2010).

The Space Shuttle Challenger Disaster

The Space Shuttle Challenger Disaster At 11:38 a.m. on Tuesday, January 28, 1986, the Space Shuttle Challenger launched from the Kennedy Space Center at Cape Canaveral, Florida. As the world watched on TV, the Challenger soared into the sky and then, shockingly, exploded just 73 seconds after take-off. All seven members of the crew, including social studies teacher Sharon Christa McAuliffe, died in the disaster. An investigation of the accident discovered that the O-rings of the right solid rocket booster had malfunctioned. Crew of the Challenger Christa McAuliffe (Teacher in Space)Dick Scobee (Commander)Mike Smith (Pilot)Ron McNair (Mission Specialist)Judy Resnik (Mission Specialist)Ellison Onizuka (Mission Specialist)Gregory Jarvis (Payload Specialist) Should the Challenger Have Launched? Around 8:30 a.m. on Tuesday, January 28, 1986, in Florida, the seven crew members of the Space Shuttle Challenger were already strapped into their seats. Though they were ready to go, NASA officials were busy deciding whether it was safe enough to launch that day. It had been extremely cold the night before, causing icicles to form under the launch pad. By morning, temperatures were still only 32 ° F. If the shuttle launched that day, it would the coldest day of any shuttle launch. Safety was a huge concern, but NASA officials were also under pressure to get the shuttle into orbit quickly. Weather and malfunctions had already caused many postponements from the original launch date, January 22. If the shuttle didnt launch by February 1, some of the science experiments and business arrangements regarding the satellite would be jeopardized. Plus, millions of people, especially students across the U.S., were waiting and watching for this particular mission to launch. A Teacher on Board Among the crew on board the Challenger that morning was Sharon Christa McAuliffe. McAuliffe, a social studies teacher at Concord High School in New Hampshire, had been chosen from 11,000 applicants to participate in the Teacher in Space Project. President Ronald Reagan created this project in August 1984 in an effort to increase public interest in the U.S. space program. The teacher chosen would become the first private citizen in space. A teacher, a wife, and a mother of two, McAuliffe represented the average, good-natured citizen. She became the face of NASA for nearly a year before the launch, and the public adored her. The Launch A little after 11:00 a.m. on that cold morning, NASA told the crew that launch was a go. At 11:38 a.m., the Space Shuttle Challenger launched from Pad 39-B at the Kennedy Space Center at Cape Canaveral, Florida. At first, everything seemed to go well. However, 73 seconds after lift-off, Mission Control heard Pilot Mike Smith say, Uh oh! Then people at Mission Control, observers on the ground, and millions of children and adults across the nation watched as the Space Shuttle Challenger exploded. The nation was shocked. To this day, many remember exactly where they were and what they were doing when they heard that the Challenger had exploded. It remains a defining moment in the 20th century. Search and Recovery An hour after the explosion, search and recovery planes and ships searched for survivors and wreckage. Though some pieces of the shuttle floated on the surface of the Atlantic Ocean, much of it had sunken to the bottom. No survivors were found.  On January 31, 1986, three days after the disaster, a memorial service was held for the fallen heroes. What Went Wrong? Everyone wanted to know what had gone wrong. On February 3, 1986, President Reagan established the Presidential Commission on the Space Shuttle Challenger Accident. Former Secretary of State William Rogers chaired the commission, whose members included Sally Ride, Neil Armstrong, and Chuck Yeager. The Rogers Commission carefully studied pictures, video, and debris from the accident. The Commission determined that the accident was caused by a failure in the O-rings of the right solid rocket booster. O-rings sealed the pieces of the rocket booster together. From multiple uses and especially because of the extreme cold on that day, an O-ring on the right rocket booster had become brittle. Once launched, the weak O-ring allowed fire to escape from the rocket booster. The fire melted a support beam that held the booster in place. The booster, then mobile, hit the fuel tank, causing the explosion. Upon further research, it was determined that there had been multiple, unheeded warnings about the potential problems with the O-rings. The Crew Cabin On March 8, 1986, just over five weeks after the explosion, a search team found the crew cabin; it had not been destroyed in the explosion. The bodies of all seven crew members were found, still strapped into their seats. Autopsies were done but exact cause of death was inconclusive. It is believed that at least some of the crew survived the explosion, since three of four emergency air packs found had been deployed. After the explosion, the crew cabin fell over 50,000 feet and hit the water at approximately 200 miles per hour. No one could have survived the impact.

Satisfaction includes a user’s feelings, perceptions, and opinion about the system. Information is usually collected through written and oral means (Rubin & Chisnell 2008). Finally, accessibility involves the capability of the system to allow persons with disabilities to perceive, understand, navigate, and interact with it. In performing usability tests, two basic principles should always be remembered: (1) a designer’s perception on the system design is different from the target audience; and (2) it is better to conduct multi ple tests with a few users rather than running a single test with a large number of users. Usability tests usually involve either getting an audience evaluation of the system or having a usability design expert perform a heuristic evaluation of the program. One drawback of heuristic evaluation is that the expert reviewer may not share the same perception as the target users or may identify errors that target users do not consider as problems. In contrast, an audience evaluation of the system is a credible representation of a real-world user’s needs and perceptions of the system... of determining the ideal number of users to comprise a usability test group, the following guidelines are recommended: (1) too few users yield inferior results since the users may not be able to identify most of the problems; and (2) too many users would increase the chance that most users would identify the same problem and reduces the chances that the users will be able to identify less obvious errors (Silver 2005). There are four types of usability tests which a developer may choose from depending on the situation: (1) exploratory; (2) assessment; (3) evaluation; and (4) comparison. Exploratory testing is usually performed in the early part of the design stage. It has to primary objectives. First, to verify of the functions selected to be used in the system are useful and appropriate for the user. Second, to determine the degree as to which the system design matches the user’s mental model of the system. A mental model is described as a user’s assumptions and expecta tions regarding how certain tasks are accomplished (Silver, 2005). One important feature of an exploratory test is the high degree of freedom a developer can attain in developing early designs of the system. By using tools such as paper screens and system prototypes with limited functionalities, the developer can collect important information and feedback from the users. This allows the developer to determine if the initial design matches user perception of the system. In addition, exploratory tests enable developers to detect serious flaws in the design before a mode concrete plan of the system is created (Rubin & Chisnell, 2008). In an exploratory test, a moderator may provide the user with screenshots of the system and ask if all the types of information or functions that the user expected to be
