CogTool - Essay Example The types of modeling techniques used are AI and cognitive modeling. Examples of modeling are the following: Sisyphus, Project Halo, Ambr. Project and Predicting Cognitive Performance. The differences existing in the models depend on the person’s or team’s modeling approach. Predictions related to similar performing model take place because of a similar approach which remains unknown. Comparison of modelers relies on approaches used to predict time that is spent by skilled performers on the various user interfaces (UIs). Heuristic estimation techniques are compared to predictive human performance modeling approach, the Keystroke-Level Model (KLM). Method of Study The KLM approach was compared with data from 19 novice modelers in building two UIs tasks. The data was published originated from 8 novice modelers. The variance for the data collected was approximately 20%. This evaluator effect in Human-Computer Interaction (HCI) is revealed in various techniques of HCI. The 20% evaluator effect for all the techniques faced critics on use in KLM modeling technique because of its assumption that it predicted accuracy of 20%. The differences in modeler techniques are based on expected accuracy that emphasizes on behavior representation community. Attempts to reduce variation in modelers are provided for by tool-support for KLM analyses. The human-centered design (HCD) techniques used created CogTool, a tool to construct valid KLMs. Error Detection Detection for systemic errors was done on examination of eight KLM novice modelers. 87 operators were compared with inclusion of KLM created. Many common errors were detected. Overt steps essential for task operation were left out. Accurate follow up of the Ks, Ps, and Hs in KLMs was impossible, making the task unsuccessful. 88% of modelers experienced this error. 38% of the novice modelers included extra overt operators unnecessary for the task. The novice modelers experienced difficulties in applying Moran and Newell’s heuristics when placing M operators. This was characterized by uneven placing of Ms in the models. The errors discovered were analyzed through human centered design techniques that prompted design of CogTool (Bonnie). Results of Research: CogTool Project CogTool project allows UI designers to predict human performance modeling techniques analyze ideas in design from a quantitative approach before implementing ideas on resource investment. Error analysis mentioned was used as a guideline in design of CogTool project so that the errors identified could be eliminated to the utmost. Contextual inquiry was used to understand the challenges faced by modelers and the success of the project in suiting the workflow and culture of UI designers. Competitive analysis was used to assess what had been tried. Results obtained were considered in design of the project. Continuous analysis has made the tool of importance in today’s real-world design and evaluation processes. T his success enables it to be taught to HCI, UI design and Human Factor students. Using CogTool The procedure for KLM in CogTool is different from KLM done by hand. UI design is modeled on a graphical storyboard placed on widgets other than being listed by overt operators in spreadsheets separated from UI design. The widgets are in frames, representing what users see as they precede with others tasks. The frames are connected through transitions drawn from

Artist Statement - Essay Example Some of the information include the creature habitats and habits. Further, nocturnal photos can be used in studying the rare animals that only come out at night because during the day they hide in their caves. These animals are known as nocturne creatures. Additionally, nocturnal photos on animals can be stored in archives for future reference thus act as a source of information to researches and zoology students in educational centres. In addition, this practice of taking photos is essential in establishing the near extinction animals. Thus helps to trigger the need to protect them from extinction by establishing measures that will mitigate the rate of extinction. However, nocturnal photos promotes art because it gives artisans ideas on what to draw and even curve thus enhancing creativity. Additionally, from the curves and the drawing future generations can learn about the creatures. Moreover, this photos in a way help to market countries to tourists who are in love with animals and wish to explore more. Through this, a country will receive an increase in the number of tourists visiting their nation, hence uplifting it gross domestic product. Furthermore, the characteristics that accompany the nocturnal photos can be of great use to game wardens by educating them on how to handle those animals effectively to avoid damage or injuries since some of them are poisonous. Secondly, nocturnal photos about human beings are taken in special occasions conducted during the night. Events like film shooting, fire bourn parties and many more. Therefore, these photos can be stored and referred to in future to remember the Good times in a person’s life. Thirdly, nocturnal photos about unique structural features are used to highlight the features of a nation. By doing this it will attract tourism to their states. This structural nocturnal photos can also be places in school libraries to teach the students

The Evolving Role of Government in Education Essay - 2

The Evolving Role of Government in Education - Essay Example On the other hand, the federal government also grants the public schools’s funding; the government has a number of federal agencies, along with organizations, which are helpful in benefiting children educational necessities so as to effect their success (Sandars, 2000). In the past 2 centuries, momentous federal support of education existed, although slowly, but and steadily, while, at the same time, the increasing federal commitment to education regarding monies and policies turns to be impressive. The NCLB changes the role of the federal government within elementary, as well as secondary education by necessitating for the states, together with schools in measuring success in regards to student performance. Conversely, the federal government is also responsible for the provision of grants and scholarships to those people who are going through college or university pursuing higher education. Consequently, the NCLB also tends to be beneficial to children with a disability, since they have the similar rights and opportunities compared to other children who are not disabled of attending any school that is public, college or even university thereby enhancing their knowledge, while, at the same time, becoming successful individual (Fred & Allan, 2011). In the recent past, there was the consolidation movement whose intention was to eliminate school boards that were small, as well as rurally dominated. Although this was a perception that this was the beginning of the end, there are a number of people who perceive these efforts as education efficiency. Conversely, others view it as luck of the draw, with students, regardless of their background, tend to take an active role concerning their education, thereby getting what they desire from it (Sandars, 2000). However, the next significant move in education happens to be Board of Education vs. Brown during 1954 whereby this ruling reversed the 1896 Plessy vs. Ferguson ruling that founded the separate but

Womens Crisis Services of Waterloo Region Organization Essay

Womens Crisis Services of Waterloo Region Organization - Essay Example This paper illustrates that Haven and Anselma were functioning independently up until 2001 when they merged to form the present Women’s Crisis Services of Waterloo Region (WCSWR). This also resulted in the integration of the board of directors and the creation of the post of the executive director who has the responsibility of managing the two facilities. The adoption of a dragonfly as its logo reflects the organizations’ literal shift from violence against women and children. The tagline â€Å"Moving beyond violence† is an enhancement of the message that achievement of equality is determined by human courage and initiative to propagate human values and leave violence against women in the past. Among its services is the residential program that serves women above the age of 16 either with or without children. These women include those who are being abused intimately or experiencing problems in a domestic relationship. The organization also has the outreach and ed ucation services that work closely with the process of transitioning women to independence, and also those seeking assistance from their current abusive situations. The education program functions to provide the community and professionals with the required information on healthy relationships. Therefore, they are guided by the fact that there should be synergistic efforts towards achieving a better world without violence against women with a mission of providing shelter, education and public sensitization to all the abused women and children. Therefore, it has grown to become the subsequent vision that any form of aggression against women and children will not be tolerated by society. The organization’s central contributions lie in the empowerment of women against this vice in the advent of calls for equality among males and females. This organization is also playing a fundamental part in refining the community regarding the costs of domestic violence and the benefits of avo iding it. It is also playing a significant role in creating conflict resolutions and ways to avoid the emergence of these conflicts. In another word, it means that the organization is working on the creation, sustainability and dissemination of peace in homes hence alleviating this problem of violence that is directed by men towards women.

Dewey believes that the only real education Essay

Dewey believes that the only real education - Essay Example Those so-called educators and journalistic professionals who continue to lament the death of critical thinking among the modern youth do so because they no longer understand, nor belong, to the new age of education and information technology. Academicians and journalists tend to be resistant to changes around them and, therefore, tend to cry out that critical thinking has passed on (Males, â€Å"Critics of Student's Critical Thinking Ain't Either†). They fail to see that critical thinking has merely taken on a new shape and form. One that is consistent with the continued evolution of the critical thinking and mental capacity of the future generations of learners and academicians. The critics who view critical thinking as a dead practice among the students of today base that point of view on their incomplete observation based upon the Foundation for Critical Thinking's definition of â€Å"critical thinking† (Males, â€Å"Critics of Student's Critical Thinking Ain't Eith er† ) as: ... the intellectual scrutiny of a given statement's "purpose, problem, or question-at- issue; assumptions; concepts; empirical grounding; reasoning leading to conclusions; implications and consequences; objections from alternative viewpoints; and frame of reference. Nothing could be further from the truth. In reality, the advent of the Internet has allowed students to learn outside of the four corners of the classroom. No longer are the university professors or high school teachers viewed as infallible mentors in their areas of teaching expertise. These days, students can easily verify any given information with a few taps into a search engine. Thus, allowing them the freedom question the authority of their educators when it comes to certain information being fed to them. Students can no longer be spoon-fed these days. Instead, educators must be prepared to answer questions based upon the personal learning or research of students. The likes of Google, Bing, and Yaho o search engines have presented students with an opportunity to clarify certain information for themselves (Carr, â€Å"Is Google Making Us Stupid?† ), as class discussions have left them with more questions than answers. Then they go back to their teachers and ask them to explain further. That is why the belief that the Internet and its search engines have made our students stupid is actually without basis. The Internet has rather produced a new era of students who no longer take their teacher's word for anything. Which is why teachers now need to be more up to date and even more addicted to research via Internet than their students are if they do not wish to be shown up as lacking in actual expertise on the subjects they teach. Cable television shows and channels, such as the National Geographic, Animal Planet, Discovery, and the History Channel, have also contributed greatly to the forward thinking and critical analysis skills of the students today. While everything taught in school tends to be one-dimensional and lecture-type, these cable channels have provided students with an almost hands on learning ability about these highly interesting topics that tend to become boring when taught in school. Learning is no longer limited to Board of Education approved books with boring, black and white illustrations. These days, learning is a highly interactive process that

Artist Perception - Art and You Essay Example | Topics and Well Written Essays - 500 words

Artist Perception - Art and You - Essay Example For this reason, we cannot base our arts education on photographs and reproductions of works of art. Photographs only give two-dimensional view of an object or person resulting in omission of important aspects. Reproduction of photographs is subject to bias as the painter may decide to include what they deem fit. As a result we can never completely understand the importance of art in any given era or culture (Marmor, 1997). In order for one to gain a deeper understanding of most of the art works, they have to see the object. As was mentioned earlier, photographs and their reproductions are subject to bias. Photographers choose views and angles that they think are most appropriate, beautiful and appealing to the eyes. As a result, some very crucial information is left out. When detailed understanding of human culture is to be obtained, a researcher has to be at the site (in person) so as to gain step-by-step analysis of the object. Art is one of the most interesting things that are appreciated worldwide. Personally I love paintings since they portray human talent at work. Given a chance to visit some of the ancient paintings, I would visit Leonardo da Vinci’s painting of Monalissa. This is because da Vinci was one of the finest painters in human history. He took his time perfecting the paint every time. It is said that it took him three years to complete the master piece. I would love to find out more about the painting and da Vinci himself (Marmor, 1997) Every time a person decides to do something, they do it for a reason. The same way artists have their own reasons for doing for doing specific art works. Therefore knowing artists at personal level creates a better understanding of art works. Interaction with artists can help us understand their perspective and reasons for creating given art works (Marmor, 1997). A good
