The challenge is to convince the reader of the validity of your opinion through a well-documented, coherent, and logically structured piece of writing. Write each phrase as a mathematical expression. How did you know what the variable was. Open University Press, ; Johnson, Roy. When writing, avoid problems associated with opaque writing by keeping in mind the following: One equation for Part 2 is correct or both expressions without the total are correct e.

Academic writing relies on excellent grammar and precise word structure. In this set, there are problems that ask students to write numeric expressions without variables.

All equations given for Part 2 are correct. Consider inserting the term "sic" in brackets after the quoted word or phrase to indicate that the quotation has been transcribed exactly as found in the original source, but the source has grammar, spelling, or other errors.

Or you could view this as the sum of negative 7 and the quantity 8 times x. Student demonstrates solid understanding of the mathematical ideas and processes related to finding perimeter and writing expressions with variables to express relationships in Parts 1 and 2.

Student partially explains the importance of using the order of operations and that failing to do so accurately will result in incorrect conclusions in Part 3. What does the variable represent given the context of the problem.

So this first statement, they say the sum of negative 7 and the quantity 8 times x. Student demonstrates no understanding of the mathematical ideas and processes related to finding perimeter and writing expressions with variables to express relationships in Parts 1 and 2.

Sage Publications, ; Silvia, Paul J.

So the quantity 8 times x, well, that's just 8x. It is appropriate for you to use specialist language within your field of study, but you should avoid using such language when writing for non-academic or general audiences.

Given this, it is important that specialist terminology [i.

I ask which expression is correct for Problem 1: As they are working, I am looking specifically at problems 4 - 7. Additional Problems to Avoid In addition to understanding the use of specialized language, there are other aspects of academic writing in the social sciences that you should be aware of.

Complexity and Higher-Order Thinking Academic writing addresses complex issues that require higher-order thinking skills applied to understanding the research problem [e. In the problem above, the variable g represents the number of groups in Ms.

These can be found by either searching in the USC Libraries catalog by entering the disciplinary and the word dictionary [e. Student correctly determines if at least one of the equations in Part 3 is true or false.

What does the constant represent given the context of the problem. Refer to these three basic resources to help your grammar and writing skills: At least one part of one equation or expression for Part 2 is correct.

Throughout your paper, it is important that you present the arguments of others fairly and with an appropriate narrative tone.

I want to discuss that addition is commutative, and either expression will work.

What does the variable represent given the context of the problem. As they work, I circulate around the classroom and check in with each group. This is particularly true in academic writing because words and terminology can evolve a nuanced meaning that describes a particular idea, concept, or phenomenon derived from the epistemological culture of that discipline [e.

What amount are you starting with. In the next few examples, we will be working solely with algebraic expressions. If you make a mistake, choose a different button.

Fifteen less than twice a number. Jun 14, · This sheet addresses the first step of an algebra word problem, writing out the expression to describe the problem. This exercise is great for a child just starting to use variables, or for a child who needs to learn to take word problems one step at a time/5(4).

In this lesson you will learn how to read and write algebraic expressions by using variables. Practice writing algebraic expressions to match verbal descriptions of mathematical operations.

Expressions and variables. An algebraic expression comprises both numbers and variables together with at least one arithmetic operation. Example.

$$4\cdot x-3$$ A variable, as we learned in pre-algebra, is a letter that represents unspecified numbers. Mathplanet is licensed by. Independent and Dependent Variables Academic writing refers to a style of expression that researchers use to define the intellectual boundaries of their disciplines and their specific areas of expertise.

Characteristics of academic writing include a formal tone, use of the third-person rather than first-person perspective (usually), a clear. In this set, there are problems that ask students to write numeric expressions (without variables). I want to give students practice with writing all types of expressions.

Problem 23 will confuse some students, because the expression will be 6 -
