There are many other variables that would affect real-world riding speed, and the effort variable would also be far more complicated than represented here, but this should suffice for now. Several equations can be written using the variables defined here. For instance, to calculate the effort needed to go one kilometer (it's easier to go kilometers than miles, at least mathematically), or a thousand meters, in a given gear, the equation would look like this:

T) / G = E, where M. is the distance (in meters) of the journey, T is the circumference of the tire -- and therefore also the linear distance, G is the number of revolutions the tire goes per push of the pedal, which changes from gear to gear, and E. is the number of times the pedals have to go around, which is representative of the effort needed to push the bike forward for…

Algebra

Like many other languages and sciences, Algebra can be useful in the explanation of real-world experiences. Linear algebra, in particular, holds a high level of relevancy in the solution of real world problems like physics equations. Since the key point of physics is to explain the world in proven observations, linear algebra is an ideal mode for discussion. Many real-world situations can be explained by algebra; for example, how does GPS work? The satellite-based Global Positioning System works by locking onto the system of three satellites and calculating a two-dimensional position from latitude and longitude, thus tracking movement. The location of objects can be determined by using linear equations to morph the data into identifiable locations, and with four or more satellites in view, altitude combines with latitude and longitude to determine the 3-D position.

A far more generic (but equally important) use of linear algebra in real world…

By observing x on the graph, then we make the connection that the slope of x on the graph represents rate of change of the linear function.

Once we have done this, it is then possible to move to the development of a quadratic equation and see what the impact of the increase (or perhaps decrease) means to the data. Have we proven that the rate of change is linear? The graphical representation of the data may be misleading, so it would be good to be able to calculate the rate of change to see if it is significant.

We could assign to value of L1 to the year in which the students are enrolled collect this data in columnar form, still graphing it on our graph. We would then call L2 the number of students enrolled every year which corresponds to the year we have listed in L1. In…

Those studying physics and astronomy, and perhaps other scientific disciplines as well, are accustomed to the use of scientific shorthand and in some fields it is essential -- the example above of distance between energy waves from supernovae is a good example. There is a high level of variation in these distances, so a shorthand like the one on financial statements would be apply, but the numbers are very small so the use of shorthand is necessary. It is interesting to note, however, that even those in fields accustomed to scientific notation sometimes avoid it, as is the case with distances between objects in space.

Another group that does something similar to astronomers is the archaeologists. They have found ways to talk about years without using scientific notation, even though events often date back millions or billions of years. Yet, when discussing the science behind dating their samples, they will…

All exponential functions have as domain the set of real numbers because the domain is the set of numbers that can enter the function and enable to produce a number as output. In exponential functions whatever real number can be operated. (-infinity, infinity)

You have ln (x+4) so everything is shifted by 4. The domain of ln (x+4) is now -4 < x < infinity (Shifting infinity by a finite number gives you infinity again.) So,-4 < x < infinity is the domain of ln (x+4).

(2 [less than] t [less than] infinity)

For your function f (t) = 5.5exp (t) the function is continuous for all values of t as exp (t) is continuous for all values t, i.e. The domain of the function is -oo < t < oo

Algebra Lesson Plans and Curriculum for the 7th Grade Classroom

The National Council of Teachers of Mathematics (NCTM) provides a comprehensive set of principles and standards for developing curriculum for grades K. through 12th. Chapter two of their text Principles and Standards for School Mathematics specifies the six principles considered vital for the development of a coherent math plan. The principles are general enough to apply across a wide variety of disciplines as they are "not unique to school mathematics." (p. 16). However, chapter three dealing with the ten standards, themselves, makes quite clear (and rightly so) that math, unlike other disciplines, can benefit from a truly integrated approach: "Because mathematics as a discipline is highly interconnected the areas described by the Standards overlap and are integrated." (p. 30). In other words, the standards cannot be easily divided into particular grade levels (i.e. numbers/operations in K-2, geometry in 3-5, algebra…

algebra or geometry have no use in "real" life, many people think that statistical analyses have no possible real-world applications. However, as the following scenario should make clear, statistical analysis can be extremely helpful in assessing quality control issues in the workplace. Using a specific type of statistical analysis, the supervisor at a former workplace was able to reduce costs while increasing customer satisfaction.

Analysis of variance (more generally referred to as an ANOVA test) is one of the most basic statistical tests that can be applied to a data set. It is used to provide an accurate way to compare the results from different groups (defined in ways that are relevant to the issue at hand). Such comparisons are useful because they provide information that allows processes to become more efficient or to meet other goals, such as increasing customer satisfaction.

3b. One method that can be utilized to help Martha with applying algebra to real world application is through interactions within her environment that will allow her to utilize these skills. Another method proven useful in building applicable skills and communication is online conferencing. This tool utilized in the class room can give Martha access to knowledge from other professors and learners that could not normally be possible in a standard classroom. A professor that may specialize in a specific method on how to understand certain terms or expressions would be able to share these applications with students globally through virtual conferences. Technological Horizons (1993), recant the significance of videoconferencing by reporting that the characteristics of videoconferencing may actually enhance the learning process.

2007, p. 115). Likewise, a study by Wyndhamm and Saljo found that young algebra learners were more successful in their problem-solving efforts when collaborating in a group environment. According to these researchers, "An experiment involving 14 small groups of Swedish students (usually 3 per group) aged 10, 11, and 12 years shows that these students acting in groups and creating shared contextualizations were able to solve mathematics word problems calling for real-world knowledge. esearch has shown students acting alone to have difficulty with the same types of problems" (Wyndhamm & Saljo 1997, p. 361). Other teachers report that algebra story problems can help make learning more relevant to young people's lives. For instance, according to Homann and Lulay, "Algebra story problems are an important practical application of mathematics since real-world problems usually do not arise in terms of equations but as verbal or pictorial representations. The problems are solved by…

What is a relation schema? What is the difference between a relation, a relation schema, and a relational schema?

A relation schema is the basic information that describes a table or a relation. This includes the set of column names, the data within the columns, or the name associated with the entire table.

For example 'Students' would be the relation (I..e category) name.

The relation schema for students may be expressed as following:

Students (sid: string, name: string, login: string, age: integer, gpa: real)

It has five fields or columns each having names or types.

The relation, in other words, is the topic / category (e..g 'student'), the relations schema is the property categories of the relation, or of…

The formula is C=4d^-1/3b

D= 23,245 because it is the pounds

B= 13.5 because that is the height of the mast

C=4(23,245)^-1/3(13.5)

Because the exponent was negative it needed to be dropped down to the numerator. The fact that it was a fraction meant that 92980 needed to be cubed, since it was a 1/3 exponent. Then it could be multiplied with the B. value, which was 13.5 / This left the final answer to be 283.693745115.

Solution for the problem: (-9x3 + 3x2 -- 15x)

The division process for the polynomial above can be approached in the same way as dividing whole numbers. The polynomial (-9x3 + 3x2 -- 15x) is the dividend, while (-3x) is the divisor. To easily facilitate the division process, the whole equation will be multiplied by "-1." The new equation is: (9x3 -- 3x2 + 15x) / (3x). Writing the question in long division form, begin dividing (9x3) first by (3x), which is equal to (3x2). To cancel the first part of the equation, the first part of the quotient must be negative. Thus, 3x2 becomes (-3x2). Place (-3x2) above the division bracket as shown below.

The method the teacher uses encourages students to discover the answers for themselves rather than accept the right answer as a matter of rote learning. finally, the class is frequently divided into groups, both small and large. The groups vary to encourage maximum student interactions. Through cooperative learning the students share their suggestions and brainstorm. Finally, the teacher employs some self-directed learning strategies that allow students to ponder the equations on their own for brief periods of time. This helps the teacher make assessments during class while it also helps the students work independently.

The Semantic errors involved misuse of columns and tables - there were incompatible data types.

Semantic errors, on the other hand refer to the essential meaning of the content -- whether it all makes sense and whether it is accurate (for instance writing "the sun rises in the west") is a semantic error for this is incorrect.

According to the California standards for high school students, the geometry curriculum contains six critical components: "to establish criteria for congruence of triangles based on rigid motions; establish criteria for similarity of triangles based on dilations and proportional reasoning; informally develop explanations of circumference, area, and volume formulas; apply the Pythagorean Theorem to the coordinate plan; prove basic geometric theorems; and extend work with probability" (Common Core Standards, California Department of Education: 69). The elucidated standards are often quite specific in terms of how students are asked to apply basic concepts such as measuring angles; understanding the different properties of parallel lines; and manipulating various polygons. Not only must the students prove theorems but they must also be able to construct such shapes using a variety of methods in a hands-on fashion (Common Core Standards, 2013, California Department of Education: 70).…

Teaching as a Career

Teaching Special Education requires a gentle temperament and devotion to the children. Maturity, regardless of age, and patience is very important. Special Education teacher must be loving, kind, and nurturing in order to make the children feel safe and secure. He or she must also be focused and creative in teaching methods. nd most importantly, present a positive role model for the children. I feel that I have the qualities and experience to become an effective Special Education teacher.

My background is vast and varied. I worked as a secretary at the University of California - Los ngeles for two years. The department in which I worked dealt with the clubs and fraternities on campus, therefore, I was constantly involved with the students and problems that arose from their activities. I spent a little over two years working as an office manager for a doctor's office.…

Gordon Adam's petition is not only well argued and properly reasoned, but, additionally, it managed to prove that all the arguments given against his petition were based on false reasoning. From the entire set of arguments, the only one that could actually be used against his argumentation was the one stating that he needed college algebra in order to "satisfy the university math requirement in order to graduate." Something like when you ask why you have to pay all kinds of different taxes: you see no real benefit, but some higher authority, in this case the state, in Gordon's case, the educational system and the college authorities, convinces you that this is necessary because it is so required!

On the other hand, because the college authorities' argumentation is based on all kind of fallacies, clearly dismantled one by one in Gordon's argumentation, it is my opinion that Gordon should be…

Organizational Health

Educational institutions generally approach organizational improvement by addressing the performance standards to which students, educators, and administrators are held. The standards movement has been a dominant theme in educational policy arenas and in the public eye. With roots in the 1950s Cold War mentality, the thrust of educational improvement has been prodded by perceptions of international industrial and scientific competition. If the rigor of educational standards in the nation -- according to the logic of this argument -- falls below that of other countries, our economy will falter and the balance of trade will be compromised, perhaps beyond the point of recovery.

Fears for the future of the country and our citizens run deep; these fears propel a course of action that is not particularly based on rational thinking and lacks a base of evidence. The course of action adopted by educational policy makers and educational leaders in…

Unemployment in America

Policy makers in the United States continuously seek the silver bullet(s) -- plural solutions because there is clear recognition that the issue is multifaceted -- that will achieve healthy levels of employment in the nation. Certainly there some paths to increasing employment in the country are less expensive than others, and proposed solutions range across a wide array of complexity and practicality. Invariably, today, education becomes a focal point for discussions and debates about how to increase employment in any nation. This is due largely to the potential promise that solutions based in education can act as levers that are sufficiently effective to induce change.

Thesis Statement

Solutions to unemployment must be developed through the perfection of the alignment between the education young American receive -- in both secondary (high school) and post-secondary (college / university) educational systems -- and the actual labor market.

In his article…

These include: question/answer, lecture, demonstration, discussion, individual student projects, laboratory, technological activities, and supervised practice. Previous research has demonstrated that the use of informal knowledge, real world settings and opportunities to apply mathematical thinking are effective instruction methods for introductory algebra. For this reason, instructional factors are related to achievement in algebra (p. 102).

When comparing the test scores from Japan and the United States, House and Telese (2008) found a correlations between positive beliefs in the student's mathematical ability and their test scores. Those who believed they could do well in math performed better than those who expressed a negative opinion about their skills, when compared to their peers. In addition, students who worked problems on their own had higher test scores. This supports Silver's (1998) analysis that much of the reason why American students have poorer test scores than their international peers is due to the classroom instructional…

Once the concept of factoring is understood, technology can be used to assist the students with solving quadratic equations and equalities. The website (http://www.coolmath.com/algebra/) will be references, but the students will have to write explanations showing that they understand how at least two homework problems were solved.

4. By the time we are ready to learn inverse functions, students will have a review of everything learned during the school year building up to inverse functions. Again, technology will be used via (http://www.coolmath.com/algebra/). tudents will again be asked to write an explanation for various homework problems demonstrating that they understand the concepts behind solving it.

Evaluation Procedures:

A quiz once per week

Midterm exam covering current quarter

Final exam covering current and previous quarters

Written homework explanations demonstrating how certain problems were solved

Review near the end of the school year for all concepts learned

End of year final exam

These exams would also tap teaching performance and other capabilities unlikely to be adequately assessed using conventional paper along with pencil instruments." (Shulman, 1986, pp. 4 -- 14)

These different elements are important, because they are providing a foundation for helping the schools to become more competitive in mathematics. As, they are working together to create a basic standard for: improving learning comprehension and provide the ability to solve more complex issues. Over the course of time, this will help to increase the student's ability to understand a wide variety of concepts. This is the point that they will be more prepared to deal with the various challenges that they are facing in the 21 century. Once this occurs, it will help them to establish a foundation for adapting to the changes that they will have to deal with from: shifts in technology and through these transformations because of globalization.…

Education: Teaching Math to Students ith Disabilities

orking with students with disabilities (SD) can be quite challenging, especially for teachers working on a full-time basis. Almost every classroom today has one or more students dealing with either an emotional, educational, or physical disability; and teachers are likely to find themselves looking for resources or information that would enable them teach all their students in the most effective way. There are numerous special-education websites from which teachers and instructors can obtain information or lessons on teaching their respective subjects. Five websites available to the math special education teacher have been discussed in the subsequent sections of this text.

conveyed in an effective manner to meet the needs of students. It is an important aspect of differentiating instruction. Students with diagnosed learning disabilities will receive an IEP designed to address their specific learning issues and deficits. Presentation, response, timing (scheduling) and setting can all be addressed in differentiation. Memory; auditory, visual, and even motor processing; attention deficits; abstract reasoning issues; and organizational problems can all cause issues for students that can be improved with differentiated instruction (Ginsberg & Dolan, 2003, p. 87).

In-class assessment can take place in both in traditional formative and performance-based ways. Formative assessment is used during the learning process so the teacher can check in to see what the student has retained. This can be observational or in the form of quizzes or other graded formats. But while performance-based assessment can take the form of conventional tests there are other methods besides exams, including flexible…

Students will work together in groups of at least four to answer the questions on the exercise. Then, they will be required to present their findings to the class in a short, five-minute group presentation.

3. In order to familiarize students with the concepts and properties of triangles, quadrilaterals and other polygons, students will access the website, (http://www.explorelearning.com). Under the Mathematics Gizmos section of this website, students will select the following: Grade 9-12 > Go > Geometry. Students will be required to perform all of the interactive activities in the Triangles and Quadrilateral and Polygons sections. Students will be required to write a brief explanation of understanding for each exercise.

4. Students will pick up where they left off in the first semester by continuing to use the website (http://www.explorelearning.com) for the entire second semester. The will follow the similar path that they did during the third unit: Grade 9-12…

Environmental classes could chronicle their observations of the weather, for example, and post the results of their class observations online. Creating attractive, scientifically literate material online is an important skill that students should learn. New equipment is also needed in the laboratories to conduct more accurate measures of experiments. This is necessary to improve student performances at local science fairs.

Funding for field trips to science museums and other on-site locations to supplement education:

Interacting with science and technology in a hands-on fashion; visiting science laboratories that use technology; and meeting with individuals who use science and technology in their vocations are all ways to get students excited about technology and its applications.

Hiring a part-time or full time teacher of technology

This professional would be officially in charge of acting as a facilitator between the math and science departments; teach elective courses in technology; and conduct laboratories and educational…

The use of the Cognitive Tutor not only enriches students' experience at the academic task-level but also impacts the teachers' instructional practices and relationship with her students (Level 3) A district-wide survey of high school teachers using the program reveals that the Cognitive Tutor allows them more time to provide individual assistance to students; gives them the opportunity to adjust their instructional practices as a result of students progressing in problem solving; and makes Algebra more interesting and relevant to students (Schneyderman, 2001). These views imply that the use of the program makes teaching less burdensome in the sense that the teacher acts as facilitator of learning rather than instructor, which is one of the arguments for educational technology in general.

Due perhaps to the wide acceptance of the use of Cognitive Tutor and other instructional software in American classrooms, the "No Child Left Behind" Act called for…

Thus, in 1 Kings 7:23, the word "line" is written Kuf Vov Heh, but the Heh does not need to be there, and is not pronounced. With the extra letter, the word has a value of 111, but without it, the value is 106. (Kuf=100, Vov=6, Heh=5). The ratio of pi to 3 is very close to the ratio of 111 to 106. In other words, pi/3 = 111/106 approximately; solving for pi, is pi = 3.1415094... (Tsaban, 78). This figure is much more accurate than any other value that had been calculated up to that point, and would hold the record for the greatest number of correct digits for several hundred years afterwards. Unfortunately, very few people know this fact.

Archimedes of Greece was the first person to make serious use of the pi calculation. In 287 to 212 BC, he focused on the polygons' perimeters as opposed to…

First, math courses are required as part of college work in the pursuit of most degrees in the health care field. The level of required achievement is different, depending on the degree sought. For example, a student pursuing an LPN may take a semester or two of college algebra. A pre-med student is often required to take one or two semesters of calculus. A student pursuing a master's degree in health care administration will take courses in statistics, finance and accounting. The master's candidate can perhaps more easily see the relevance of the required math courses toward the future career. For the nursing student studying algebra or the pre-med student struggling through calculus, the correlation between academic study and actual practice may be unclear. They may wonder why they must undertake these courses, which seem to have little to do with the work in which they will eventually be engaged.…

Hypatia of Alexandria, daughter of Theon. Specifically, it will examine the life of Hypatia, especially her mathematical accomplishments. Hypatia was the first female mathematician that left a record that historians can trace. She was a philosopher, mathematician, and teacher who lived in Alexandria, Egypt from about 350 to 415 A.D. She was the daughter of Theon, a renowned mathematician and head of the library in Alexandria.

Historians do not agree on the year Hypatia was born. Some estimate it at around 355, while others place it as late as 370. What is known of Hypatia is that she was extremely influential in mathematics and philosophical thought. Hypatia was born in Alexandria and most historians believe she spent her entire life there. Some historians believe Hypatia studied mathematics in Athens, and then traveled through Europe (Coffin, 1998, p. 94), while others believe her father taught her most of what she knew…

Arizona State University (ASU) is a leading metropolitan research international institution in the United States that is committed to excellence in teaching, research, and public service. Established in Tempe in 1885 by a legislative act, ASU was initially formed as a teachers college. The core of the Tempe campus was a 20-acre cow pasture donated by leading citizens who desired an institution to educate public school teachers and offer instruction to their children in agriculture and mechanical arts.

In 2002, Michael M. Crow became the University's sixteenth president. In his inaugural address, he outlined his vision for the transformation of the school into a prototype for a new American university. This future institution will be a comprehensive research university that continues its academic excellence as well as have a strong commitment to social, economic, cultural, and environmental issues to meet the needs of the growing Phoenix area. The city has…

Take for example a human resource manager who is interested in how three different departments in a business situation waste time on the internet on a given day when they should be doing company business. The human resource person would collect data through a time study process and determine the number of times each employee in each department logs on and off the internet for personal business. The times would be collected, added together and the times of each department converted to percentages. In the example presented, the human resource manager can report that, cumulatively, the employees in Department 1 spent a total of 5 hours a day on the Internet, Department 2 employees 2 hours a day and Department 3 spent 6 hours. The raw numeric count is then converted to percentages and the pie chart would look like the following (Ohlson, 2005):

The solution to the data presented…

Inverse Equations

Problem "a" is an example of substitution equations. In this case, it is asking the two equations to be subtracted and the number four substituted for "x." In order for this operation to be properly accomplished, order of operations requires that the two problems be simplified to their final state before being combined.

Proof a.

(f-h)(4)

Problems "b" are examples of inverse functions. Here, a secondary function is being placed in the original function's "x" position. Once this is accomplished, order of operations and rules of simplification allow for the simplifying of the final expression. These cannot be entirely solved as there is no value given for "x."

Proof b.

2(x^2 -- 3) +

2x^2 -- 6 +

2x^2 -- 1

Disequilibrium in Learning

Piaget's concept of disequilibrium in learning makes a great deal of sense both in terms of child development and in terms of the general way in which humans tend to think and act. Piaget bases much of his theories on evolutionary biology, and so adaptation necessarily plays a certain role in his thinking. He theorizes that the student is always active and that learning is an action by which one constructs knowledge (hence consctructivism), but that at the same time humans tend towards stagnation, seeking to "continue in past patterns as long as possible" (Doll, 1993, p. 83) Piaget supposes that it is necessary for the teacher to create a sort of cognitive dissonance and discomfort which will shock the student out of their complacency and force them to evolve and learn. He calls this state of uneasiness which is necessary to learning "disequilibrium." The social aspect…

Precalculus With Limits by on Larson

This book as well as the other two books are for college freshman level or college introductory level mathematics courses. The strengths of the book are mainly focused on its layout. For example, the book has a great way to demonstrate a varied and large amount of information easily and simply. This means that people reading the text just have to look for certain visual cues like colors or pictures that will point the information they seek. For example, the diagrams have a different background color than the text. All of this removes time spent looking for things. The use of bold also further differentiates the text, highlighting key words, phrases and things to memorize.

The weaknesses are in lack of context surrounding the topics and footnotes. Another book reviewed has footnotes and yet another provides adequate background for each topic. This book sacrifices…

For this he can use the FOIL method. FOIL means FIST OUTSIDE INSIDE LAST. This order can help erase the confusion that arises with understanding of order in which equations are to be solved. This technique falls in the category of Mnemonics which was one of the strategies recommended for Jeffery's case. Mnemonics are any sentences or pictures that help students make connections and understand concepts.

Students often are befuddled with the use of complex terms in mathematics and hence it's recommended that they become familiar with some commonly used terms before they are used in the context of mathematics or algebra. For example students can be told what a variable is without actually referring to any mathematical equation. Variable is simply any letter in which a value can be stored. 4x for example would be the number 4 with a variable x that also contains a value though hidden…

At which point, the students would begin studying composition of functions to verify each other. There will be a brief period of one day, to review the information that was covered during the quarter. (Cox, 2006)

In the first week of August, is when a comprehensive review will take place, covering everything that was presented in the year and preparing students, for their achievement as well as quarterly examinations. At this time, is when the educator needs to be focused on spending more time with the students. In some cases, it may be prudent to set up more recitation / review sessions before or after school. The extra time that can be spent reviewing the material and covering what was presented; will help to ensure that students are prepared for their assessment as well as quarterly examination, at the same time.
