ICE BREAKERS


Types of Icebreakers:

1.      Who Done That?

Prior to the meeting, make a list of about 25 items relating to work and home life. For example, a list for a group of trainers might have some of the following:
  • Developed a computer training course
  • Has delivered coaching classes
  • Is a mother
  • Knows what ADDIE means and can readily discuss it
  • Enjoys hiking
  • Has performed process improvement
  • Served in the Armed Forces
  • Is a task analysis expert
Ensure there is plenty of space below each item (3 or 4 lines) and then make enough copies for each person.
Give each person a copy of the list and have them find someone who can sign one of the lines. Also, have them put their job title and phone number next to their names. Allow about 30 minutes for the activity. Give prizes for the first one completed, most names (you can have more that one name next to an item), last one completed, etc. This activity provides participants with a list of special project coaches and helps them to learn about each other.

2.      The ADDIE Game (Analysis, Design, Development, Implement, Evaluate)

Make up a reasonable problem scenario for your organization where people need to get introduced, e.g. “The manufacturing department is bringing in 20 temporaries to help with the peak season. They want us to build a short activity that will allow the permanent employees to meet and introduce themselves to the temporaries.” Break the group into small teams. Have them to discuss and create a solution:
  • Analyze the problem — Is it a training problem? If they decide that it is not a training problem, then remind them that most problems can be solved by following an ADDIE type approach.
  • Perform a short task analysis — How do people get to know each other?
  • Design the activity — Develop objectives, sequence.
  • Develop the activity — Outline how they will perform the activity and trial it.
  • Implement — Have each small team in turn, introduce themselves in front of the group using the activity they created.
  • Evaluate — Give prizes to the most original, funniest, etc. by having the group vote.
This activity allows them to learn about each other's problem solving styles and instructional development methods, it also introduces the members to each other. This method can also be used to introduce the ADDIE method to new trainers. Time — about 60 minutes.


3.      Expectations
Meeting Expectations Can Make or Break Your Class.
Expectations are powerful, especially when you're teaching adults. Understanding your students' expectations of the course you're teaching is key to your success. Make sure you know what your students expect with this expectations ice breaker.

Ideal Size:

Up to 20. Divide larger groups.

Use for:

Introductions in the classroom or at a meeting, to understand what every participant is expecting to learn from the class or gathering.

Time Needed:

15-20 minutes, depending on the size of the group.

Materials Needed:

A flip chart or white board, and markers.

Instructions:

Write Expectations at the top of a flip chart or white board.
When it’s time for students to introduce themselves, explain that expectations are powerful, and that understanding them is key to the success of any class. Tell the group that you would like them to:
  • Introduce themselves
  • Share their expectations of the class
  • Add a wild prediction of the best possible outcome should their expectations be met. Ask them to be as specific as possible, and encourage silliness or fun if you want.

Example:

Hi, my name is Deb, and I’m expecting to learn how to handle difficult or challenging people, and my wildest expectation is that if I knew how to do that, nobody would ever get under my skin again. Ever.

Debrief:

State your objectives of the course, review the list of expectations the group made, and explain whether or not, and why, if not, their expectations will or won't be covered in the course.
4.      Zoom and Re-Zoom
A group tries to create a unified story from a set of sequential pictures.  The pictures are randomly ordered and handed out.  Each person has a picture but cannot show it to others. Requires patience, communication, and perspective taking in order to recreate the story's sequence.
Group Size
  • 20 to 30 ideal, but can be done with fewer (see variations)
Time
Total time~20-30 minutes
  • ~5 mins set up and brief the group
  • ~15 mins active problem solving
  • ~5-10 minutes debrief
This is a novel icebreaker by handing each participant a picture on arrival.  When everyone has arrived, explain that each person is holding part of a story and that the group task is to find out what the story is by putting their pictures in sequence.
This can also be mapped to story telling part of the ID.

5.      Frame Game

Give each learner four blank cards and instruct them to fill in four different responses on the subject: “What were main concepts or learning points of the material we just covered?” Give them about five minutes to complete the exercise, then collect the cards, shuffle them, and randomly deal three cards to each learner. (Note: If desired, the trainer can make up four cards of her own, but they should be philosophically unacceptable with the principles presented. That is, play devil's advocate.)
Ask everyone to read the cards they just received, and then to arrange them in order of personal preference.
Place the extra cards on the table and allow them to replace the cards in their hand that they do not like. Next, ask them to exchange cards with each other. They must exchange at least one card.
After about three minutes, form them into teams and ask each team to select the three cards they like the best. Give them time to choose, then have them create a graphic poster to reflect the final three cards.
Select or vote on best poster that best represents the topic.
This can be used to discuss how to include interactivity. We can replace the ‘responses’ in this game by ‘interactivity options’ for a given senario.

6.      Ball-Toss

This is a semi-review and wake-up exercise when covering material that requires heavy concentration. Have everyone stand up and form a resemblance of a circle. It does not have to be perfect, but they should all be facing in, looking at each other. Toss a nerf ball or bean bag to a person and have tell what they thought was the most important learning concept was. They then toss the ball to someone and that person explains what they though was the most important concept. Continue the exercise until everyone has caught the ball at least once and explained an important concept of the material just covered.

7.      Process Ball

This is similar to the above exercise, but each person tells one step of a process or concept when the ball is tossed to them. The instructor or learner, in turn, writes it on a chalkboard or flip chart. For example, after covering “Maslow's Hierarchy of Needs,” you would start the ball toss by having everyone give one step in the pyramid of needs, e.g. Safety, Physiological, Esteem, etc.

8.      The Magic Wand

You have just found a magic wand that allows you to change three work related activities. You can change anything you want. How would you change yourself, your job, your boss, coworkers, an important project, etc.? Have them discuss why it is important to make the change. Another variation is to have them discuss what they would change if they become the boss for a month. This activity helps them to learn about others' desires and frustrations.
9.      People bingo
Bingo is one of the most popular ice breakers because it’s so easy to customize for your particular group and situation, and everyone knows how to play it.

Ideal Size

Up to 30. Divide larger groups.

Use For

Introductions in the classroom or at a meeting.

Time Needed

30 minutes, depending on the size of the group.

Materials Needed

Bingo cards. See instructions below.

Instructions

If you know your participants, make a list of 25 interesting traits that describe different aspects of them, things like, “plays the bongos,” “once lived in Sweden,” “has a karate trophy,” “has twins,” “collects children’s art,” “has a tattoo.”
If you don’t know your participants, make a list of more general traits like “drinks tea instead of coffee”, “loves the color orange,” “has two cats,” “drives a hybrid,” “went on a cruise in the last year.” You can make these easy or difficult depending on how much time you want the game to take.
There are lots of places online where you can type in your traits and print your own customized cards. Some are free; some are not.
  • Teachnology has a card maker that allows you to shuffle the phrases on each card.
  • Print-Bingo.com allows you to customize with your own words or use their suggestions.
If you’re making your own, bingo cards have five boxes across and five boxes down. B-I-N-G-O! A simple table in Word does the trick. Fill in the boxes on a master and make copies. Leave room for signatures.
When you’re ready to play, give each participant a bingo card and a pen. Explain that the group has 30 minutes to mingle, introducing themselves, and finding people who match the traits on the card. They must put the person’s name in the corresponding box or have the person sign the appropriate square.
The first person to fill five boxes across or down yells BINGO! and the game is over.
Ask participants to introduce themselves and share one of the interesting traits they learned about someone else.

Debriefing

Debrief by asking for volunteers to share how they feel differently about the others in the group now that they know a few things about them. When we take the time to get to know each other, barriers dissolve, people open up, and learning can take place.

Working Backwwards


Assessment format:

The strategy of working backwards essentially means that the student starts with the end results and reverses the steps, in order to figure out the answer to the problem. Such a strategy is used to solve problems that include a number of linked factors or events, where some of the information has not been provided, usually at the beginning of the problem. Such a strategy is also extremely useful in dealing with a situation or a sequence of events. The events occur one after the other and each stage, or piece of information, is affected by what comes next. Students begin at the end, with the final action, and work through the process in reverse order to establish what happened in the original situation.
To solve these problems it is necessary to start working methodically backwards, in a logical step-by-step way, to fill in the missing information. Generally, two types of problems can be solved using this strategy:
  1. When the goal is singular and there are a variety of alternative routes to take.  In this situation, the strategy of working backwards allows us to ascertain which of the alternative routes was optimal.

A Simple example of the above: An example of this is when you are trying to figure out the best route to take to get from your house to a store.  You would first look at what neighborhood the store is in and trace the optimal route backwards on a map to your home.

  1. When end results are given or known in the problem and you're asked for the initial conditions.
Example: A group of 28 students went to the science museum to see the fossils
exhibit. The museum collected Rs.1000 from the students. How much was the
admission for each student?.

The underlying purpose of this kind of assessment is for the instructor to understand student learning in a step wise manner and then modify the lesson/activity accordingly. The purpose of such an assessment is that students can apply logical reasoning and sequencing to events to solve a problem. The only caution that the instructor should take is that the problem should be properly worded and there should not be an element of ambiguity.

What is an appropriate situation (eg in-class/HW/exam etc) to assign this format of question?
This type of question can be given both in class as well as for homework. Both situations have their respective advantages..if it is given as a classroom task then the students can get realtime feedback from the instructor regarding their progress but time might be a constraint in this setting. Whereas if it is given as a homework activity then, the student gets enough time to logically determine the steps that he would be following. But, in both the cases, this should be an individual activity each student might follow a different approach to the problem and the instructor will get a good idea of the problem solving abilities of each child.

Converting this into a multiple choice question:
In such questions, there can be multiple correct answers..and hence the student is given the flexibility to present his/her answer.

Example: Ratio and Proportions:
The age of the father 10 years ago was thrice the age of his son. Ten years hence, father’s age will be twice that of his son. The following can be the ratio of their ages:
  1. 7:2
  2. 5:6
  3. 7:3
  4. 91:39
  5. c but not d
  6. Both c and d
In this question we know that both (c) and (d) are the correct answers. Thus, in this way this question can be converted to a multiple choice question.

Another example:
Mom gave me 50 Perks and 125 Cadburys and asked me to make as many jars of candies as were possible with each jar containing 5 Perks and 13 Cadburys. How many jars could I make up? How many Perks and how many Cadburys would be left over?

What are Journals?


What is a Journal?

A journal is a publication that is published both in a particular format and is issued at fixed intervals (eg. weekly, monthly, and yearly). Journals can also be referred to as periodicals, magazines and serials. There are many different types of journals available. Understanding the type of journal will help you identify whether or not the articles will be of value to you in your research.

Types of Journals


  • Peer Reviewed Journals

“A publication is considered to be peer reviewed if its articles go through an official editorial process that involves review and approval by the author's peers (people who are experts in the same subject area). Most (but not all) scholarly publications are peer reviewed.” (Proquest database information, 2007)

  • Scholarly/Academic Journals

A publication is scholarly when the articles’ authors are academics/scholars /researchers /experts in the field. There may be a review or refereeing process. The articles will be supported by bibliographies and will assume readers’ prior knowledge of the subject.

  • Magazines or Popular Journals

Popular journals or magazines are available in many formats. The content is often written by the magazine staff. The content is entertaining with minimal analysis. A magazine usually contains a miscellaneous collection of articles, stories, poems, and pictures and is directed at the general reading public

  • Trade Journals

These are written to give information aimed at specific professions, trades or businesses. They are often practical in nature and are written by specialists in particular fields. They focus on matters concerning a particular industry or group of industries. Also called a "trade publication"

  • Current Affairs/Opinion

These are written to give general information covering a range of topics. They are often written by journalists but can have articles by scholars. There may be a specific bias (e.g. with political journals).

  • Professional Organisation / Society Journals

These are produced by particular professional organisations to give information to specific professions. The articles may be written by staff journalists or by experts in certain fields.

  • Newspapers

Newspapers are designed to cover breaking news. The quality of information ranges from high to sensationalist content. The articles are usually written by staff journalists with no author acknowledgement. There can also be features written by specialists whose name is given -- a “Byline” -- which gives the name, and often the position, of the writer of the article.

Journal Articles

In Peer Reviewed and Scholarly journals you can be confident that published articles are of a high research standard and academic in focus. (Note: Not all articles in a peer reviewed journal are refereed, e.g. letters to editors.) How do you know if an article found in a journal is from a peer reviewed journal? How can you identify peer reviewed journals? The following can assist you to find whether or not a journal is peer reviewed.


  • Ulrich’s Periodical directory Available online through the Library Catalogue

Provides information on serials published throughout the world. It covers all subjects, and includes publications that are published regularly or irregularly. Nearly a quarter of a million consumer and trade magazines, academic and scholarly publications, monographic series, newsletters, newspapers, electronic publications, 'zines, and many other types of serial publications and services published throughout the world on all subjects, are profiled. Details covered include standard bibliographic data, price, plus where a given title is indexed and/or abstracted. Ulrich's International Periodical Directory is a very useful guide to serial literature. It is also one of the few sources for determining the status of a serial title e.g. whether a title is a trade publication, peer reviewed etc.

  • Using a Database to find articles

o Some databases identify peer reviewed journal titles
o Some databases allow you to Limit your search to refereed/peer reviewed articles by either ticking a checkbox or using Advanced Search to search a Publication Type field.
o Check the Database Help information for ways of identifying article types.
(Note: Databases often make mistakes when deciding whether or not an article is peer reviewed. To make sure, check the journal’s website.)

  • Individual journals

o Examine the individual journal’s website. The information aimed at authors wanting to submit articles should indicate whether or not there is a review process.


Tips for Evaluating Other Journal and Newspaper Articles

The following criteria should be applied to articles where you are not sure they have been through a review/referee process:

  • Where did you find the article?

o Finding the article in a subject index, e.g. PsycInfo, the article is more likely to be a scholarly or even peer reviewed article.
o If the article is from a general index, e.g. a Newspaper source, then it is not likely to be peer reviewed, but it may be scholarly.

  • Author

o Is the author named?
o Are the author’s qualifications / credentials / professional associations given?
o Can you identify an institution, if any, to which the author belongs?
o Is contact information for the author included?

  • What is the purpose of the article?

o Is the article designed to sell a product or service?
o Is the article giving facts that you already know are correct?
o Is the article in a journal you know to have a bias?
o Is the article presenting research findings?

  • Audience

o Who is the intended audience?
o General public and at what age level?
o Other academics or scholars?

  • Language

o Is the language of a high scholarly order?
o Is the language sensationalist?
o Is the language level low and sometimes inflammatory?

  • Type of Journal

o What does the journal look like?
o Who is the publisher? Is it a professional organisation / commercial publisher / university / scholarly society?
o Are there pictures/images? Are they appropriate to content as in research findings or are they sensationalist?
o Is there advertising? If so, who is the advertising aimed at?
  • Article appearance

o Are there footnotes and/or a bibliography?
o Is there an abstract?

Mixture Problems


MIXTURE PROBLEMS involve creating a mixture from two or more things, and then determining some quantity (percentage, price, etc) of the resulting mixture.

Your school is holding a "family friendly" event this weekend. Students have been pre-selling tickets to the event; adult tickets are $5.00, and child tickets (for kids six years old and under) are $2.50. From past experience, you expect about 13,000 people to attend the event. But this is the first year in which tickets prices have been reduced for the younger children, so you really don't know how many child tickets and how many adult tickets you can expect to sell. Your boss wants you to estimate the expected ticket revenue. You decide to use the information from the pre-sold tickets to estimate the ratio of adults to children, and figure the expected revenue from this information.
You consult with your student ticket-sellers, and discover that they have not been keeping track of how many child tickets they have sold. The tickets are identical, until the ticket-seller punches a hole in the ticket, indicating that it is a child ticket. But they don't remember how many holes they've punched. They only know that they've sold 548 tickets for $2460. How much revenue from each of child and adult tickets can you expect?
To solve this, we need to figure out the ratio of tickets that have already been sold. If we work methodically, we can find the answer.
Let A stand for the number of adult tickets pre-sold, and C stand for the child tickets pre-sold. Then A + C = 548. Also, since each adult ticket cost $5.00, then ($5.00)A stands for the revenue brought in from the adult tickets pre-sold; likewise, ($2.50)C stands for the revenue brought in from the child tickets. Then the total income so far is given by ($5.00)A + ($2.50)C = $2460. But we can only solve an equation with one variable, not two. So look again at that first equation. If A + C = 548, then A = 548 – C (or C = 548 – A; it doesn't matter which variable you solve for). Organizing this information in a grid, we get:

tickets sold
$/ticket
total $
adult
548 – C
$5
$5(548 – C)
child
C
$2.50
$2.50C
total
548
---
$2460
From the last column, we get (total $ from the adult tickets) plus (total $ from the child tickets) is (the total $ so far), or, as an equation:
($5.00)(548 – C) + ($2.50)C = $2460
$2740 – ($5.00)C + ($2.50)C = $2460

$2740 – ($2.50)C = $2460

–($2.50)C = –$280

C = –$280/–$2.50 = 112
Then 112 child tickets were pre-sold, so A = 548 – 112 = 436 adult tickets were sold. (Using "A" and "C" for our variables, instead of "x" and "y", was helpful, because the variables suggested what they stood for. We knew instantly that "C = 112" meant "112 child tickets". This is a useful technique.)
Now we need to figure out how many adult and child tickets we can expect to sell overall. Since 436 out of 548 pre-sold tickets were adult tickets, then we can expect 436/548, or about 79.6%, of the total tickets sold to be adult tickets. Since we expect about 13,000 people, this works out to about 10,343 adult tickets. (You can find this value by using proportions, by the way.) The remaining 2657 tickets will be child tickets. Then the expected total ticket revenue totals to $58,357.50, of which ($5.00)(10,343) = $51,715 will come from adult tickets, and ($2.50)(2,657) = $6,642.50 will come from child tickets.

Let's try another one. This time, suppose you work in a lab. You need a 15% acid solution for a certain test, but your supplier only ships a 10% solution and a 30% solution. Rather than pay the hefty surcharge to have the supplier make a 15% solution, you decide to mix 10% solution with 30% solution, to make your own 15% solution. You need 10 liters of the 15% acid solution. How many liters of 10% solution and 30% solution should you use?
Let x stand for the number of liters of 10% solution, and let y stand for the number of liters of 30% solution. (The labeling of variables is, in this case, very important, because "x" and "y" are not at all suggestive of what they stand for. If we don't label, we won't be able to interpret our answer in the end.) For mixture problems, it is often very helpful to do a grid:

liters sol'n
percent acid
total liters acid
10% sol'n
x
0.10
0.10x
30% sol'n
y
0.30
0.30y
mixture
x + y = 10
0.15
(0.15)(10) = 1.5
Since x + y = 10, then x = 10 – y. Using this, we can substitute for x in our grid, and eliminate one of the variables:   Copyright © Elizabeth Stapel 1999-2011 All Rights Reserved

liters sol'n
percent acid
liters acid
10% sol'n
10 – y
0.10
0.10(10 – y)
30% sol'n
y
0.30
0.30y
mixture
x + y = 10
0.15
(0.15)(10) = 1.5
When the problem is set up like this, you can usually use the last column to write your equation: The liters of acid from the 10% solution, plus the liters of acid in the 30% solution, add up to the liters of acid in the 15% solution. Then:
0.10(10 y) + 0.30y = 1.5
1
0.10y + 0.30y = 1.5
1 + 0.20y = 1.5

0.20y = 0.5

y = 0.5/0.20 = 2.5
Then we need 2.5 liters of the 30% solution, and x = 10 – y = 10 – 2.5 = 7.5 liters of the 10% solution. (If you think about it, this makes sense. Fifteen percent is closer to 10% than to 30%, so we ought to need more 10% solution in our mix.)

Usually, these exercises are fairly easy to solve once you've found the equations.

Giving a Good Research Talk

Read this article somewhere, and thought it was worth sharing, could not find the authors...

Purpose
Why give a talk? A talk is an advertisement for the paper. If people are sufficiently interested, they will read the paper. To repeat excellent advice from Peyton Jones et al: what is the one thing listeners should remember from your talk? You should know this, and your audience should too -- tell them!
Structure
Don't try to present the entire paper in the talk. Some details will have to be omitted. Also, the structure of the talk may not match the structure of the paper. In coming up with a simple, clear structure for the talk, you may realise that the talk structure is clearer and better than the original paper's structure.
Slides
Slides accompanying a talk can serve up to three distinct purposes, each one for a different group of people:
  1. For the audience: they make the talk easier to follow and understand.
  2. For the speaker: they serve as speaking notes.
  3. For people not at the talk: they can be read later, to learn what the talk was about.
Purpose 1 is the most important. Audience understanding is helped most when you present information that is difficult to communicate by voice: pictures, graphs, tables, equations, small code snippets, web addresses, etc. It is also useful to show key phrases or definitions. Text beyond that should be sparing. (An interesting question: does every slide need a title?) Less is more.
Purpose 2 is less important, and it conflicts with purpose 1. Obviously, you don't want to forget important things, but you shouldn't expose the audience to the mechanics of how you achieve this. Presentation software like PowerPoint allows you to add notes to a presentation that are not visible when the talk is given. Use them. You can even script every word of the talk in these notes. (This really helps in making sure the talk goes for the same length every time.) But be careful: writing and speaking are different. Many sentences that are fine when written down sound stiff when spoken. You may need to rewrite the notes multiple times to match how you naturally speak.
Purpose 3 is also less important, and also conflicts with purpose 1. Again, audience-invisible notes can solve this problem. However, talks often do get distributed in a form (such as PDF) in which any additional notes are not visible. Therefore, you probably want to think about purpose 3 to some extent, and put the most important points in a form that is brief but intelligible to someone who didn't attend the talk. But don't go overboard -- if they want more information, they should read the accompanying paper.
It is amazingly hard to write slides that truly, primarily serve purpose 1, and not get sucked in by purposes 2 and 3. In particular, when you first write the slides it's natural to write lots of bullet points and whole sentences of text, because you write down everything that you want to say. Once you've done this, try to remove as much text as possible, by (a) converting text to other forms (and note that small animations can be invaluable for guiding an audience's attention around a picture), and (b) presenting the remaining text as concisely as possible. This is hard work -- text is faster to create than pictures, tables, etc -- but it results in a much better talk.
Laptops
If you can, check beforehand that the connection to the projector works, to avoid embarrassing technical problems. Also, have backed-up versions of your talk in at least one other place: a website, a CD, a USB keychain, or on transparencies.
Get laptops ready as much as possible before you start to minimise fiddling time. This means starting PowerPoint (or whatever you're using) and having your first slide loaded ready to go. The worst thing you can do is plug your machine into the projector, so everyone can see the machine's display, then boot it up. It will take one minute but feel like ten.
Ending
Make it obvious when you have finished! Otherwise you will have those excruciating few seconds of silence while the audience decides whether to applaud. It mostly comes down to the tone of your voice. If you finish with a sentence that clearly wraps things up and then say "thank you" in the right tone, it's obvious you have finished and the audience will applaud. Practice beforehand, it's easy.
Don't just trail off. Don't mumble "and that's about it". If you have a moderator, don't ask for questions -- it's their job; if you do it, the audience will be unsure whether to applaud, which can be awkward. If you don't have a moderator, ask for questions after the applause.
Length
Don't exceed your time limit. It's rude, and annoying for the listeners. If you don't time yourself before to get this right, you will almost certainly overrun.
How many slides do you have? Time per slide varies between speakers, and between talks. However, if you have 25 minutes and 35 full slides, that is too many
