Did Someone Say Research Poster?

Did you get a research poster accepted at a conference lately? Congratulations! So did the NTO.

The NN/LM Training Office (NTO) had a poster accepted for the 2016 Joint conference of the Midcontinental and the Midwest MLA chapters and I have been tasked with doing a preliminary layout for the poster. So I set off into the Internet to find some help on designing a research poster.

Font size

Justin Matthews’ name popped up on several of the searches I did. Here is what he has to say about fonts:

Why is font size important?

  • Font size can help draw your viewer’s eyes to specific parts of your poster.
  • Use font size to convey importance.

Teaching topics: Openers and Closers

Did you miss NTO’s free webinar “Teaching Topics: Open and Close with Impact” last Thursday? If you weren’t a part of the 80-strong attendees, have no fear, for a recorded edition is being sliced and diced for our YouTube channel right now.  In the meantime, this post will review several classroom activities & concepts discussed in our webinar. (But not everything! For that you’ll have to wait for the video and/or our next scheduled webinar.)

First off, what is an opener and a closer? These are classroom activities that frame an instruction session.  A popular misconception in instructional metaphor is to think of a class like a sandwich – the opener and closer are the bread, while the content – what you really want folks to learn – is the meat.

This is wrong.

Why? Serial position effect.

Serial position effect is defined as “a tendency for the items near the beginning and end of the series to be recalled best, and those in the middle worst” (1). Serial position effect was coined in the 1910s by Hermann Ebbinghaus, a psychologist who also invented the learning curve. The implications of serial position effect for instruction is that the opening and closing portions of the class are just as important as the meat of your content.

So toss out that learning sandwich, and consider the churro.


The churro is a sugary fried donut item. It is delicious from first bite to last. Churros are long and cylindrical. Towards the middle of your eating experience it may be easy to lapse into a sucrose-sprinkled complacency and forget to appreciate the churro, but once down to the last bite, the churro will live on as a tasty memory. So let’s consider instruction a churro, and openers and closers as your first and last bite. Fresh examples after the jump.

Gagné’s nine events of instruction as demonstrated by cats

Robert Gagné is an educational scholar noted for his work on the nine events of instruction that are necessary for successful learning to occur. It is designed as a framework to be used to design a class. Gagné’s book, Principles of Instructional Design (1992) (1), outlined these nine instructional events on a theoretical and practical level. Today, we will explore these nine events through something to which most librarians can relate: cats. We will also give concrete examples of how these nine events can apply to teaching a PubMed class. Perhaps we will even discover a serendipitous intersection of cats, PubMed, and instructional design theory. Nine lives, nine instructional events, how could this ever go wrong?

Word Clouds as Discussion Starters

I like word clouds. They help us see what’s important or most prevalent in a block of text. When the NTO was the NTC, we used word clouds to help facilitate a discussion in our PubMed for Trainers class about the core competencies of PubMed.

We asked students: Is there a set of core competencies that all users need to search PubMed effectively? Students posted their answers in a Discussion Board and then we took the text (after we cleaned it up a bit) and put it into the word cloud generator. During class, we displayed the word cloud and used it as a tool to stimulate a class discussion.

We liked this technique because we (the instructors) already knew what the students thought (as displayed by the word cloud), the rest of the class could see if their set of core competencies matched what others thought and we could ask people to elaborate or ask if there were any surprises.

Word Cloud

Three word cloud generator tools:

  3. Google Docs has a word cloud Add-in.

Here’s a short video by Richard Byrne about using the Google Doc Word Cloud add-in. Note, the add-in mentioned in the video has been renamed Tag Cloud.

A Year with PubMed – Up Close and Personal

Posted on behalf of Cheryl Rowan.

Over the past thirteen months I have had the privilege of working as a Trainer/Curriculum and Content Specialist with the NN/LM National Training Center (now National Training Office). During this time, one of my primary roles has been to provide training on PubMed and I have learned more than I ever thought possible about this amazing resource from the National Library of Medicine. I’ve learned about ATM (not to be confused with an Automated Teller Machine!), automatic explosion, MeSH, EOYP, conveyor belts, supplemental concepts, the NLM catalog, and much, much more.

At the “end of the day,” so to speak, I’d like to offer my unsolicited version of Top 5 Things to Know about PubMed:

1) PubMed currently provides access to more than 26 million citations from biomedical literature – 26 million!!! That’s an awful lot. And, it’s all paid for by our tax dollars, which makes access to PubMed “free” to anyone, anywhere in the world who has the Internet.

2) PubMed is “smart.” In fact, there are so many awesome algorithms and other programming wonders which work behind the scenes that I can get really good results for a search with just using basic search terms, at least most of the time.

3) There is a large team of really smart people who work at NLM to make sure that PubMed keeps running 24/7 to provide the best possible results for any search.

4) There is an almost infinite variety of ways to do a search in PubMed, and very few that are absolutely the “right” way. Collaborating with colleagues provides insights into ways of doing a search that I may not have ever thought of.

5) here will always be more to know about PubMed!

Finally, NLM and the NTO offer a wide range of tutorials, webinars, and online classes on PubMed. Take advantage of this great training and remember, there’s always more to learn!

NLM Releases TOXinvaders, a Mobile Game about Chemistry, the Environment and Health

The Division of Specialized Information Services (SIS) of the National Library of Medicine (NLM) launched TOXinvaders, an environmental health and toxicology game for iPhone and iPad, available from the Apple Store (

TOXinvaders supports middle school science concepts pertaining to chemistry, environment and health. It can serve as an engaging classroom or homework activity for middle and high school students, as well as an entertaining learning activity for gaming aficionados of all ages. In the classroom environment, TOXinvaders works best as a supplement to NLM Tox Town, Environmental Health Student Portal, TOXMAP, and ChemIDplus web sites.


The game consists of four fast-paced levels, in which a launcher is used to annihilate toxic chemicals falling from the sky and earn protective shield points by capturing “good chemicals.” To move on to the next level, players must take a brief quiz about its chemicals in order to unlock the next one. These dynamically generated tests provide an excellent opportunity to learn more about environmental health and toxicology, either from the game’s chemical information sheet, or from NLM Web sites. Quiz questions and answers can also serve as a departure point for classroom discussions, as well as Tox Town, TOXMAP, and Environmental Health Student Portal activities and experiments.

Sometimes, zero isn’t everything

Did you attend MLA 2016 in Toronto? Did you hear Dr. Ben Goldacre give the McGovern Lecture?  One of the things he spoke about was representing statistics in charts and that pesky Y axis. The YouTube video below does not contradict Goldacre, but shows how sometimes zero can get in the way.
