Helping Students Overcome Math Problems

Helping Students Overcome Math ProblemsStudents who encounter math problems tend to feel a sense of frustration and overwhelm. Students also tend to hesitate when it comes to the next class. They may even think that math problems are too difficult for them to solve and to get through them. This can result in students becoming discouraged, which can lead to a lack of concentration, inability to stay on task, and a decrease in their overall performance.Students that struggle with math problems are usually intimidated by it. They worry that they will mess up, they will be embarrassed if they make a mistake, or they just do not feel confident that they will be able to solve it. These are all valid fears that need to be addressed. Even though you may have a friend or a teacher that has been faced with this same type of situation in the past, they are generally not experts in math.To help students overcome their fears, they need to understand what math problems are. The first step in under standing math problems is to identify the purpose of every math test. Many tests are designed to help students decide whether they should continue or need more instruction. Many students learn best by being exposed to information in a logical sequence. Therefore, students need to learn to identify the main point of the material they are taking.Students also need to ask themselves questions like, 'What is the main point of this lesson?' and 'How can I learn this material in the shortest amount of time possible?' Each question that students ask will help them find the main idea and how to learn it in the most efficient way possible.Once students have determined the main point of the lesson, they need to try to understand the main point of the problem. It is important to remember that not all math problems are created equal. Some students will need more work than others. However, students need to know the main point of the lesson before they start learning.Another way to help students overcome their fears about math mathematical problems is to use math games that are designed for students that are shy or nervous about math. Games such as Sudoku, crossword puzzles, word searches, and other math games that involve problem solving and research are helpful in easing the student's mind and making them feel comfortable. Doing these types of math activities will not only help students solve math problems, but will also help them become more confident in their ability to solve problems and figure out problems on their own.Students also need to be aware of the kind of materials that they are using to learn math problems. Some students struggle because they need to memorize patterns that they have seen in the past. They may even become afraid that if they repeat a pattern in the wrong way, they will make a mistake. These kinds of materials can actually distract students from their main goal of learning and can make it more difficult to memorize.The key to overcoming math p roblems is to eliminate any and all barriers to learning. Students need to develop an attitude of confidence and self-esteem. By facing their fears, they will develop more confidence and perform better on tests.

Artificial Intelligence is easily one of the most prevalent themes in all of science fiction. The idea that a machine could exhibit the same level of intellect and sentience as a human, has long since been the basis for captivating audiences creators alike. From an ominous computer system in 2001:A Space Odyssey, to superhuman androids in Westworld. This fascinating sub-genre of science fiction has experienced a diverse range of depictions. The thing with fiction is that it has a habit of romanticizing certain aspects of artificial intelligence.

Assuming it’s possible, what happens when machines become more competent at performing any and all physical and mental labor? If AI becomes more competent in every regard then what purpose or function would be left for us to serve?

Essay on The Importance of Identity in Homers Odyssey

The Importance of Identity in Homers Odyssey Within the epic poem The Odyssey, Homer presents the story of Odysseuss quest to find his home and his identity. According to Homers account, with its origin in oral tradition, the two quests are interchangeable, as a mortal defines himself with his home, his geographic origin, his ancestors, his offspring, etc. But in addition to this Homer illustrates the other aspect of human identity, shaped by the individual and his actions so that he may be recognized in the outside world. Through this Homer presents Odysseus in two ways: the first his internally given identity as ruler and native of Ithaca, son of Laertes, father of Telemachos; the second the definition of the external world†¦show more content†¦Homer presents this clearly in the following instances: Helens description of Odysseus disguising himself to enter into the city of Troy and in doing so gaining information that would allow him to destroy his mortal enemies, a trademark ploy that he also uses when returning to his homeland of Ithaca to infiltrate the rank of suitors; additionally in the sequence with the Cyclops in which Odysseus eludes danger by taking on the guise of Noman or one without a name. For Odysseus, the ability to disguise his identity presents an opportunity through which he can conquer his enemies at Troy and thereby establish great fame and external identity through public recognition. Through the voice of Helen, Homer demonstrates how Odysseus became so unrecognizable that he was able to enter into Troy, defying both his mortal enemies and the immortal Poseidon who built Troys walls to be impenetrable: But what a deed this one mighty man did and dared... When he had submitted himself to disfiguring blows, He threw a poor covering over his shoulders and in the likeness Of a servant he entered the enemys broad-streeted city...

Glass is not suitable cell material for use in UV spectroscopy because the glass only suitable for measure visible and glass will absorbed UV light ,for the conclusion the data will be affected. 2. State one advantage of using the UV-Vis spectrophotometer compared to a spectronic 20 for this analysis. UV-Vis spectrophotometer can measure UV and Visible but spectronic only can use to visible. CALCULATION DISCUSSION From the graph absorbance versus wavelength, the sample concentration use is 5ppm so the graph obtained is small. The maximum wavelength get from the graph is 527. 0 because of the higher absorbance. There is some mistake occur during the preparation of the 5ppm and 10ppm that make the data get not accurate. The data from the graph show that 5ppm and 10ppm not on the linear line because problem in dilution of the sample. The dilution problem occur because during the measurement of the volume needed to dilute using the burette ,the eye not perpendicular on the burette that make the volume is more than 5ml and 10ml that make the graph show high absorbance at the 5ppm and 10ppm. The correlation coefficient can be defined by measure the strength of the straight line or the relationship between the two or more variable in the data. The correlation coefficient denoted by r and the value between +1 and -1. From the data obtained, the correlation coefficient is 0. 99142. This value show that the graph not too straight line because the sample at 5ppm and 10ppm, the absorbance is high that make the graph of straight line not too strong. CONCLUSION As the conclusion, the maximum wavelength for the potassium permanganate is 527. 0nm. The concentration of the unknown solution of potassium permanganate is 15. 2ppm. The correlation coefficient is 0. 99142 . REFFERENCES 1. http://www. dmstat1. com/res/TheCorrelationCoefficientDefined. html 2. The basic instrumental analysis lab manual.
