This module defines primary and secondary sources, offers examples of each, and provides criteria for distinguishing between these two types of sources. In addition, the module offers strategies and criteria to follow for determining the reliability of a research reference and provides examples of reliable and unreliable sources.

Objectives:

Students will learn that reference sources can be highly reliable; yet, some can be very unreliable. This is especially true with sources found on the Internet. When evaluating sources, students should consider the following questions:

  1. What are the author’s credentials?
  2. Is the author an authority on the subject?
  3. Who published the work?
  4. Is the work current?
  5. How accurate is the information?
  6. Is the information reliable?
  7. Is research objectively presented?
  8. Who is the intended audience?

Students will learn to differentiate between primary and secondary research and sources and understand that primary sources answer the following five questions affirmatively :

Defining primary sources

  1. Was the author present at the time of the event?
  2. Is the report an eyewitness account?
  3. Is the work original? Was it written or created at the time of the event?
  4. Does the information come from personal accounts, experiences, or reports?
  5. Are conclusions drawn from first hand evidence?

Students will also learn that secondary sources respond favorably to the following five questions:

Defining secondary sources

  1. Does the author present second-hand accounts of events?
  2. Does the source interpret information offered by primary sources?
  3. Does the information offer judgments, conjectures, and/or conclusions about events reported in primary sources?
  4. Does someone other than the creator interpret the creative work?
  5. Are theories, facts, results, or discoveries analyzed, evaluated, and/or interpreted second-hand?

Teaching strategies:

The instructor should review all material prior to teaching this lesson. In addition, instructors should ensure that students understand how to evaluate sources wisely. The instructor should review reliable and unreliable sources of information and offer examples of each. In the slide show, definitions and examples of reliable, unreliable, primary, and secondary sources are provided. Students should learn to define and discriminate between each type of source.

Materials:

In order to offer this lesson, instructors need a computer and a multi-media projector.

The following materials and handouts are provided with this module:

  1. PowerPoint slide show
  2. A hand-out of the slide show for students after they receive the lesson
  3. One practice sheet with primary and secondary source exercises
  4. Answer sheets for the practice exercises

Assessment:

The authors recommend that the instructor distribute the practice sheet to the students as a pre-test prior to receiving the lesson. After completing the lesson, students should answer the practice sheet again as a post-test. In this way, instructors may determine whether the students master this objective or require additional instructional support.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
