Example

Attendance

• Student leader takes each day• 10% of grade!!!• You must notify me by email (include student

#) if you cannot make it to class or if you missed because of illness or other excusable reason.

Presentation requirements (20%)• Presentations start on Wednesday May 21st.• We will provide titles for presentations.• Presentation in Powerpoint (In English)• 10 minutes long, 2 minutes for questions• Must tell a logical story

Grading presentations

– Quality of slides: titles, conclusion at base of each, bullets no sentences

– Quality of graphics (not pixelated)– Talk structure: introduction, – Subject matter– Presentation skill (voice, English, not reading

notes)

Audience (team) participation (10%)

• After two or three talks (1 lecture), you will work in teams on discussion questions (provided by me).

• Five teams (6 or 7 students in each)• Write down discussion question• You will write down your teams’ conclusions• All students must sign their’s teams paper• This will count for your participation

Audience (team) participation (Examples)

• How would you use the internet to find out if a chemical is commercially available?

• How would you discover all of the scientific papers of Professor Zhiping Zheng (from the University of Arizona) using the internet?

Your team would discuss and write an short answer to questions, sign the paper and turn in.

Quizzes (15% of grade)• Three quizzes• You will have 30 minutes to take.• I will provide a Study quide for you to prepare

with.• NOT a team effort. Work by yourselves. No

copying of your neighbor’s quiz answers.• Quizes will be during 1) 4th period on Friday,

First week Presentation Topics: May 21 & 23rd

1. Explain how the internet works. 2. Presentation of history of internet.3. How search engines work 4. Describe search engines available to you here in China.5. Describe how a VPN works6. Explain how to build a complete list of publications for a

scientist.. 7. Discovering where a scientist has worked (company or

government lab or University).8. Conducting author searches (how do you know you have

the right Professor Zhe Li??). 9. Chemical searching: How do you use the internet to tell

you if a chemical compound is new and has not been reported before?

10.Research topic searching. 11.Finding a chemical reactions or formulation using

chemical search engines

Part 2. Giving effective presentations

Douglas Loy

Networking and Chemistry

Story telling tools• Visual-graphics• Strong load voice & eye contact• Slide title is a thesis

for slide• Reinforced with bullets of information• Finish each slide with conclusion or transition

Together these grab your audience’s attention and deliver your message more effectivelyEmail: daloy@mse.arizona.edu

9-11 Slides should do it.

Title: Giving presentations

is easy

Introduction/background:

Organize your information

Presenting is easy because,

It is just telling a story.

Logical sequence of information

Don’t put everything you

On your slides.

Leave some things for the audience to ask about.

Conclusion: repeat thesis

from first slide.Acknowledgments

The title slide

• Introduce yourself • Paraphrase title of talk if possible• Introduce thesis during title slide. • Presenter must explain why this talk is

important or interesting to audience.

The proper use of the title is to inform the reader of the talk’s

thesis

Douglas Loy

HIT, Harbin, Heilongjong, PRC

Presentations tell a story

Beginning of talk: tell audience what they should learn (thesis)

Middle of talk: explain & defend thesis and reinforce

End of talk: repeat thesis clearly

People like to hear a logical story with a satisfying conclusionEmail: daloy@mse.arizona.edu

Applying the KISS (Keep It Simple Silly) Principle

• One concept or theme per slide• Try to keep it to 4 or 5 bullets max per slide• Simple, easy to understand graphics• Font greater than 18.

Simple, easy to understand slides that focus will leave your audience with your message more effectively

This is an awful graphic!!!!!Email: daloy@mse.arizona.edu

No outlines in short talks

• Absolutely useless for short talks (& most long ones)

• Waste of time at best, Insulting at worst• If you must, make it a map for complicated

presentations

Talks can be “outlined” on the first slideBut don’t waste your time or the audience with a special outline slide Borin

For historical background, use a time line graphic

1860 20101900

1920 1940 1960 1980

20001950

1930 1970

Don’t go overboard with details• Leave fine details for audience questions• Do not set yourself up for questions you can’t

answer• Keep presentation at higher level (not the

dreaded “graduate student seminar”)

The corollary is that you should be identifying potential questions and organizing your answers before you present

Keep your talk length under control

• Start with one slide per minute• Practice and determine how many you will

actually will need

If you have too many slides your audience will not remember your message, only your lack of preparationEmail: daloy@mse.arizona.edu

Conclusion slide is where you revisit key points from presentation

• Do not save important points until conclusion• Paraphrase those points after introducing

them earlier.• Can be the conclusion bullets from slides

You can often end your summarizing the talks take home points by speculating about the future.

Responsibilities of Audience during presentation

• NO talking, eating, cell phones ringing, texting, writing on computers unless its about the presentation

• Listen, because test material will be included in presentations.

• Clap when speaker is finished.• Raise hand to ask question. Stand and

introduce yourself then ask question.

Speaker answering questions• Design slides to direct audience to questions

you want asked.• Don’t put everything you know on your slides,

leave off things so you can answer questions.• Repeat question back to audience:• “The question is….”• If you don’t know, ask the speaker to rephrase

question or tell them you do not understand the question.

Part 3: The Internet

What you need to know about the internet:

• Definition of internet• Computer architecture of internet• What are protocols; what do they do?• What POP, ISP and IP are; what do they do?• What are routers; what do they do?• What is a LAN ; what does it do?• What is an http ; what does it do?• How a browser and search engine are similar and different• What is a url ; what is it for?• What is the backbone of the internet ; what does it do?• What is the world wide web?• What is a firewall ; what does it do?• What is a VPN; what does it do?

The internet: global computer network

• Network of computer systems spanning the globe.• Network of networks• Share a common protocol suite (TCP/IP)• > 2 billion users• Internet Engineering Task Force• Internet Corporation for Assigned Names and

Numbers• Access to data (WWW) and communication (email)• No central administration

History of Internet• Packet research in 1960’s• ARPANET (DARPA-US), NPL (UK), CYCLADES (FR), Telenet

(US), Tymnet (US) in early 1970’s• Computer Science Network (NSF, US,1982) • 1980’s TCP/IP standardization

– NSFNET 1986 (10-50 kb/s)• ARPANET & NSFNET replaced by commercial internet corp.’s 1990’s• since 1990’s Email, video calls, blogs social networking, WWW, etc. (> 10 Gib/s).

One more how the internet works slide

Servers store information

Client is your phone, ipad, computer

nodes interconnection points

routers are the brains of the internet:joins networks. insures info only goes where it is needed and that it does get there.

Packets are the data fragment your request or answer is broken into for transit through the internet

Search engines• Software designed to find (search) information on world

wide web• Use webcrawler and indexing algorithms to keep up to data

directory of data• Many commercial search engines (Google (89%),Yahoo,

Baidu (62% in China))• Scientific search engines: Web of Science, SciFinder,

Google Scholar

Some are free others cost to buy license.

Part 4. Searching for chemical information on the internet

What you need to know about searching for chemical information on the internet

1) what search engines are available (Scifinder, web of science, reaxys, Google scholar).2) how to find Chemical Abstracts System numbers- they are assigned to each and every chemical.3) how to search by author names and find all of their publications4) how to find out where people worked by finding their resume or curriculum vita online.5) how to search with keywords6) that structure searching can be the best way to find a CAS number or all of the references there are for that compound.7) How to find CAS #, alternative names, and citations for polymers.8) How to search for reactions9) How to search for patents10) How to sort or down select citation lists by where, when, and for whom it was done11) How to export citation lists to bibliographic software12) How to find companies selling chemicals and their prices13) How to find the first time something was done.14) Sort by document type.
