...October 10th 2013 QUESTION 1 Explain the following variables with their categories. For example: categorical, continuous, discrete or qualitative or quantitative. 1. Nominal 2. Ordinal 3. Dichotomous 4. Interval 5. Ratio Answer: We need to grasp the different types of variables we may discover while doing our dissertation. Categorical variables and Continuous variables are the main types of variables. Categorical variables are also known as qualitative or discrete variables while continuous variables are known as quantitative variables. Categorical variables can be differentiated as: * Nominal * Dichotomous * Ordinal Categorical variables have categories or rates/level that is used to describe how the variables should be controlled, measured or presented. Continuous variables can be differentiated as: * Interval * Ratio Continuous variables are always within the form of numerical value which is used to describe how variables should be controlled, measured or presented. 1. Nominal Nominal variables cannot be ordered which is meant they cannot be measured by levels (e.g. a scale from 1 to 5) but by two or more categories (e.g. blue, black, brown or blonde hair). Nominal variables can answer questions such as: a. Gender : Male or Female b. Type of property : a house, apartment or bungalow c. Hair colors : blond, brown, red hair, black, etc d. Blood type: A, B, AB or O For example: Question : What is your...

...tessellations and the polygons that can be tessellated and those that can’t. Finally, tessellations are used in real world applications. Examples are given of tessellated buildings and tessellations found in nature. Tessellations: Mathematical Art What is a term used for the tiling a surface without gaps or overlaps? The term is Tessellation. The Math Forum states that “ a tessellation is created when a shape is repeated over and over again covering a plane without any gaps or overlaps” (“What is a Tessellation?”, n.d) Early cultures used tessellations to cover the floors and ceilings of buildings, many of its artistic elements can be found in many early cultures (Hoopes-Myers, 2010). Tessellations are also found in the nature. A perfect example of nature’s tessellation is the honeycomb of the honeybee; there are no gaps or overlaps in its hexagonal shapes. In Ireland, a volcanic episode created tessellations in the landscape of The Giant’s Causeway (“Giant’s Causeway” n.d.). Artists like M. C Escher use tessellations to create fascinating works of art. In his works Escher concentrated on tessellations and repeated forms. Mathematicians and scientists embraced Escher’s works because they involved the concepts of “geometry, logic, space and infinity” (M.C. Escher Biography, n.d.). One doesn’t have to be a mathematician to tessellate but knowing...

...terminology is a necessary condition for overall mathematics achievement. If the learning of mathematics is highly dependent on its language and the teaching of math vocabulary is crucial, it is doubly so for ELLs. English language learners in secondary schools should have many opportunities to communicate their mathematical ideas and questions. Talking and writing about their mathematical thinking helps ELLs build word knowledge and oral expression and clarify their thinking. Discussions with the teacher or peers are also useful monitoring tools for teachers. Through listening and recording student conversations and peer problem solving, teachers can monitor individual student progress. Mathematics is no longer viewed as isolated, individualistic, or competitive. Mathematics problems are ideally suited to cooperative group discussions because they have solutions that can be objectively demonstrated. Students can persuade one another by the logic of their arguments. Mathematics problems can often be solved by several different approaches, and students in groups can discuss the merits of different proposed solutions (Robertson, Davidson, & Dees, 1994). For this and several other reasons mentioned throughout this chapter, cooperative learning takes a central place in mathematics instruction. Teaching and Learning Meaningful Math The lesson template for ExC-ELL is the same as that described in previous...

...[Question 1, 2 & 3 assessed students’ procedural fluency using number bonds as a mathematical operation for addition. 73.3% of the class population was able to write the correct answers to referenced questions while 6.7% of the class population knew the correct answer but wrote their answers as backward numbers. Nevertheless, writing numbers backward is not an unusual occurrence for 1st graders; it is usually corrected before they transition to 2nd grade. In all, data shows that 80% of the class population demonstrated fluency with math facts. Therefore, my major concern is the remaining 20% of the class population that provided wrong answers to referenced questions. All but one student showed that they did not have enduring understanding about the concept of addition; they could not demonstrate nor transfer their knowledge of addition when asked to solve the straightforward addition operation in question 8. Question 4, 5 & 8 assessed conceptual knowledge of the addition of numbers totaling 8,9,10. 46.7% of the class population was able to accurately provide answers to questions that represent put together situations using number bonds and straightforward addition...

...Goal: Students will use the trigonometric ratios (Sine, Cosine, and Tangent) to measure the real life height of various objects. How: Students will work with one partner, however they both will have to turn in individual projects. Step One Create a clinometer, by following these steps. ▪ Cut out the photocopied protractor. ▪ Glue it to your piece of cardboard. ▪ Cut out the cardboard so that it is the shape of your protractor ▪ Cut a 4-inch piece of string, tape it to the middle of the protractor by your mark. It is important that you tape your string before you tape your straw. ▪ Tape your straw to the top flat end of your protractor. ▪ At the end of the string, tape a couple pennies to it. Your clinometer should look like this: [pic] Step Two Measure the height of the wall using sine, cosine, tangent, and your clinometer. ▪ In order to measure the height of the wall, complete the Clinometer worksheet that is attached to this project sheet. ▪ After you measure the height of the wall, you will measure one more object at school, and one more at home for homework. Step Three Draw a story/cartoon that shows how you used trigonometry to solve the problem that...

...teaching GCSE maths re-sits has changed during the course. My thinking about teaching GCSE maths re-sits has changed in that I’m more focused on improving the learning of my students. Simplistically, before it may have been a case of “What do they need to know?” and then relaying what the student needs to know for that particular subject, in a clear and concise manner, which may have been “got” by most students, but then they would have forgot the method shortly afterwards when it came to a formative or a summative assessment. Now I’m more determined to help students learn in a way that is going to be enjoyable to them and help them remember what they need to for the exam. This will involve doing more kinaesthetic and visual activities as a lot of learners learn by doing. Realistic Mathematics Education (RME) The course has introduced me to Hodder Education’s range of books called ‘Making Sense of Maths’ for KS3 and KS4 (http://www.hoddereducation.co.uk/makingsenseofmaths). Mr Gough, a maths teacher and one of the authors of the aforementioned book(s) states the following: “My experience of teaching GCSE Foundation Tier is that by the time they get to KS4 they’ve already covered most of the content and they’re having the same content repeated in the same way that they found difficult in the first place so my experience of using this approach is that it seemed very different to them and it reinvigorated their interest in maths and they were very positive about maths lessons...

...Mathematical Programming The Mathematical Programming Add-in constructs models that can be solved using the Solver Add-in or one of the solution add-ins provided in the collection. When the Math Programming add-in is installed, several new command lines are added to the OR_MM menu. The menu items under the title Math Programming create models of the different types. Selecting an item from this list causes a dialog box to be presented which constructs a mathematical programming model. The models created by the add-in are solved with the Excel Solver, the Jensen Network Solver or the Jensen LP/IP Solver. All are Excel add-ins. Documentation for these programs can be reached by clicking the links on the lower left. The Solver add-in comes with Excel, and it can solve linear programming, integer programming and nonlinear programming models. The Math Programming add-in automatically builds Solver models and calls the computational procedures that solve the problems. All four model types can be can be solved in this way.
