the reading is reliable or

Evaluating Technical and Academic Texts

A report on the study of different cooking oils made this statement “When choosing fats, olive oil is the healthiest choice”.

One of the organizations above paid for the study. How does that change your feeling about the statement?

Identifying Details

Details are individual facts that support the

main idea.

Sometimes details are grouped into small


Major details are those that unite all the other


Minor details support the major detail.

Identify the supporting evidence in the reading below.

Social health insurance is where a nation's entire population is eligible for health care coverage and this coverage and the services provided are regulated. Additionally in almost every country, state or municipality with a government health care system a parallel private, and usually for-profit, system is allowed to operate. This is sometimes referred to as two-tier health care. For example the United States currently operates under a mixed market health care system. Government sources account for 45% of U.S. health care expenditures.

Private sources account for the remainder of costs, with 38% of people receiving health coverage through their employers and 17% arising from other private payment such as private insurance and out-of-pocket co-pays. Health system reform in the United States usually focuses around three suggested systems, with proposals currently underway to integrate these systems in various ways to provide a number of health care options. First is single-payer, a term meant to describe a single agency managing a single system. Second are employer or individual insurance mandates. Finally, there is consumer-driven health, in which systems, consumers, and patients have more control of how they access care.

Practice Identifying Supporting Evidence…

Over the past thirty years, most of the nation's health care has moved from the second model operating with not-for-profit institutions to the third model operating with for-profit institutions; the greater problems with this approach have been the gradual deregulation of Health Maintenance Operators (HMOs) resulting in fewer of the promised choices for consumers, and the steady increase in consumer cost that has marginalized consumers and burdened states with excessive urgent health care costs that are avoided when consumers have adequate access to preventive health care.

understanding writing patterns
Understanding Writing Patterns

A writing pattern is the way a writer uses

supporting evidence.

A pattern is something that repeats, which

causes it to be predictable.

understanding writing patterns1
Understanding Writing Patterns

A writing pattern is a way of organizing and

repeating elements within a piece of writing

to help make the form and content


Readers read many different texts that follow

different patterns. After time, readers

become able to predicthow different texts

will be organized.

important writing patterns for health science students
Important Writing Patterns for Health Science Students

Health Science students are primarily interested in communicating:

How things work.  Process pattern

How things are similar or different from one another.

Comparison and Contrast pattern

How things impact or affect one another.

Cause and Effect pattern

process pattern
Process Pattern

Things come in a specific order for an important reason.

Read the following text. Why has it been ordered in this way? What clues help guide your reading?

Operation of a Blood Glucose Meter

First wash your hands and dry them well before doing the test.

Next use an alcohol pad to clean the area that you're going to prick. With many glucose meters, you get a drop of blood from your fingertip. After that, prick yourself (usually finger) with a sterile lancet to get a drop of blood. Then place the drop of blood on the test strip. Finally, follow the instructions for inserting the test strip into the glucose meter. The meter will give you a number for your blood sugar level.

process pattern1
Process Pattern

Common process pattern clues include:

  • Colons (:), semicolons (;), or numbers.
  • Transition phrases like ‘first’, ‘next’, and ‘finally’.
  • References to steps, dates, or times.
  • Words like ‘series’, ‘process’, or ‘sequence’.
comparison and contrast pattern
Comparison and Contrast Pattern

Things are presented in terms of similarities, differences or both.

Read the selection below. What is being compared or contrasted? How do you know?

Halon differs from all other extinguishing agents in the way it puts out fire. Its essential extinguishing ability lies in its capacity to chemically react with the oxygen and put out the fire immediately, without leaving the kind of mess and damage that can be caused to electrical equipment by water, foam or dry powder. Like carbon dioxide, halon is unsuitable for use in open areas. If you spray it into the open air, it disperses almost as soon as it is sprayed, but it is highly effective in closed areas. Carbon dioxide works by displacing all of the oxygen in the compartment, suffocating the fire. Halon, on the other hand, works by chemically interrupting the burning process, which means that it requires a fraction of the amount.

Morgan & Regan (2008)

comparison and contrast pattern1
Comparison and Contrast Pattern

Common comparison and contrast pattern

clues include:

  • Compound sentences
  • Comparison expressions like ‘similarly’, ‘likewise’, and ‘both’.
  • Contrast expressions like ‘on the other hand’, ‘although’, ‘unlike’, and ‘however’.
cause and effect pattern
Cause and Effect Pattern

Things are discussed in terms of conditions, reasons, or results.

Read the following text. What is the cause? What is the effect? How do you know?

Why Asthma?

The reason for the increase in asthma in children is not known, but it may be due to more widespread use of vaccines and antibiotics as well asto the fact that children are spending more time indoors, or to both. Increased use of vaccines and antibiotics may have shifted the activity of a special subgroup of white blood cells (called lymphocytes) in the body from fighting infection to releasing chemical substances that promote the development of allergies. Alternatively, because children are spending more time indoors and living in better-insulated homes than they were in the past, the exposure to potentially allergic substances is increased. There are few data to support either theory.

cause and effect pattern1
Cause and Effect Pattern

Common cause and effect pattern clues


  • Look for complex sentences – especially “If…then” or “When…then”.
  • Transition words like because, consequence, result, effect, cause, due to, etc.
examining evidence
Examining Evidence

Evidenceincludes everything that is used to determine or demonstrate the truth of an assertion about something.

Examining Evidence

Evidence is gathered in various ways,

such as:

Theory Evidence

This is where one uses

conjecture or opinion to

support a concept. This

This is where you prove

by directly observing or

experimenting. This

Types of Evidence

Read the following extract and decide is this kind of

research based on theory or with empirical evidence.

Almost 100 students took experiments in which they drove virtual

cars. While driving they had to provide answers about the layout of

buildings on their campus, or check that statements made by

others about relative positions of building were correct. The

researchers monitored various aspects of their driving performance

while they performed these tasks.

Look at the following extract

The evidence in the extract above is presented with a foot note. The

number represents a footnote at the bottom of the page or sometimes

at the end of an article where you can find proof of the facts being


The statement

“A positive attitude is a very important aspect of aging. Many older people have the

same negative stereotypes about aging that young people do”.

Is based on research that was done by J.W. Rowe and

R.L. Kahn in their book Successful Aging. Which was

published in 1998 in New York by Dell Publishing.

ways evidence is presented3
Ways Evidence is Presented

Evidence that is supported with proof of a study or

research is empirical and based in findings.

When presented, this is usually presented with a

footnote, reference or indication of the study’s support.

Evidence that is opinion based or in the theory stage

and has no basis in fact is not supported. This would

therefore have no reference points.
