When you go to university you expect to learn certain things. A math program should teach you mathematics, a biology program should teach you about living things. Author: Kevin Potoczny, Biomedical Science student, University of 蓝莓视频 蓝莓视频, Ontario

Job descriptions

Job descriptions are a good thing. Whether you clean the streets or transplant hearts, it鈥檚 beneficial to know exactly what you鈥檙e to do. It informs 鈥� and protects 鈥� you and your clients and your boss. Author: Michael P Jansen, Crescent School, Toronto, Ontario

My approach to laboratory work 鈥� and everything else

A student cannot learn what he or she doesn鈥檛 understand

You may have heard me rant against formal lab reports. I have no time for this waste of time. Having high school students copy a list of equipment/chemicals, regurgitate a recipe and write what they were supposed to observe strikes me 鈥� and my students 鈥� as pointless.

Advice for veteran teachers

How to best guide new teachers

As this school year ends, probably the last thing on your mind is those new teachers who are just graduating from teacher鈥檚 college and starting fresh at your school this September. But trust me, they are thinking about September and they will need your help. Author: Katherine Mansfield, 蓝莓视频 District School Board, 蓝莓视频, Ontario

State of the laboratory

Why? Do you want to die younger than you should? Chemicals spilled all over the balances and benches. Dirty weighing paper and scoops and spatulas鈥�. Unlabeled vials scattered everywhere. Dirty dishes left any old where, and God only knows where the EXPENSIVE stir bars have gone鈥� Author: Robert W. Reed, Chemistry Lab Coordinator, University of Guelph, Guelph, Ontario

Thank you . . . or blank you

We need to think like economists

Yesterday, I heard a student bragging about the thousands of hours he spent playing a certain on-line game. That鈥檚 right, folks, you read correctly 鈥� thousands鈥�

The good fight

I couldn鈥檛 care less what you think about politics. If you agree with my views 鈥� fine; if you don鈥檛 鈥� fine. Conservatives (small or large 鈥淐鈥�), Socialists, Liberals, Libertarians, Communists, Greens鈥� whatever鈥� I鈥檓 okay. Talk all you want. I鈥檒l listen 鈥� or at least look like I am 鈥� and I鈥檒l nod and maybe smile. I might even 鈥渁gree鈥� with your hare-brained notions. Same deal with religion 鈥� say what you like, I don鈥檛 mind. My hot button is education.

The (real) reason why chemists need mathematics

One of the most common questions (and points of contention) that arises in discussions of any advanced chemistry curriculum is: why do chemists need so much training in mathematics? People on the 鈥榩ro鈥� side of the discussion usually point to examples, saying 鈥淨uantum chemistry is applied mathematics!鈥� or 鈥淗ow can you do thermodynamics or chemical kinetics without knowing some calculus?鈥�

My take on significant digits

Last summer, my wife鈥檚 friend told me that she was planning to sunbathe on the rooftop patio of her condo. I told her to apply extra sunscreen 鈥� she鈥檒l be closer to the sun.

Assumptions: Part 2 鈥� Fact versus theory: electronegativity

In the first article of the series, I discussed the assumptions behind the preparation of solutions; i.e., why are volumes not always additive? In the second article of the series, I would like to discuss the confusion that arises in the minds of some of our students between fact and theory, with particular attention to the concept of electronegativity.

Calorimeter calculations with aqueous electrolytes

In her article 鈥�2016 Canadian Chemistry Contest: Worst discriminators鈥� (March 2017, Chem 13 News) Jennifer Pitt-Lainsbury described her analysis of a CCC question with a low discriminating index and asked for comments (see boxes, below). She challenged us to look more critically at all of our tests and evaluations and ask whether they evaluate what we think they are evaluating.

A good problem relating to the gas laws

Coleman Powermax fuel is a liquid fuel for camp stoves. Before this product was discontinued, it was sold in aluminium canisters.

An earned 鈥済olden鈥� ticket to rewrite

I always start my senior level classes by asking them this question: 鈥淲hen you鈥檙e out of high school, regardless of where you are going, who is going to be responsible for you?鈥� For some, it is the first time they have thought about the fact that from now on they will truly have to take ownership of their education.

The logistics of running a practical exam (Part 2)

In Part 1 of this series1 I expressed my rationale for replacing my final written exam with a practical exam. The following are some questions I have received in regard to the logistics of a 5-day practical exam.

Scavenger hunt

This is an excellent activity to use for review at the end of the semester.

Extra! Extra! Read all about it! Teacher replaces written final with a practical lab exam (Part 1)

Winston Churchill once wrote, 鈥淭here is nothing wrong with change, if it is in the right direction.鈥� It was indeed not an easy decision to leave the time-honoured convention of a final written exam and replace it with a final practical exam in my chemistry courses.

Should Harriet Brooks be on a Canadian banknote?

Canadian readers of Chem13 News will be aware that it is planned to have a woman鈥檚 portrait on the next Canadian $10 banknote and proposals have been invited.聽But which one?

Proper use (I mean chemical educational use) of Facebook!

Facebook, let鈥檚 face it, was not designed as an educational medium. But after a few on and off attempts to use social media over the years, thanks to my students, I have recently been able to moderate a social media group that has helped stimulate interest in chemistry and other sciences.

How much is a chemistry teacher worth?

For all that we value ourselves, we hardly seem to be featured on either stamps or banknotes 鈥� though many famous chemists do. In 1991 I was given this Ethiopian note (no longer legal tender), which was then equivalent to $US 25.

Requirement of laboratory safety training on teacher certification

There is a myth in education that both school administrations and students believe. They believe that because their science, art and engineering faculty went to school for a long time, the faculty will know about lab safety and will make sure that students are not harmed.

A 鈥渨in-win鈥� lab exam

I have a suggestion that I hope will please you 鈥� and your students. It concerns a special lab exam. Let me explain 鈥� in broad strokes 鈥� what I do and how I do it.

Cheating is such a frustrating part of my job. I know that kids cheat on homework assignments and lab reports. So I have to work to safeguard my assignments from mindless regurgitation of facts. I create assignments with answers that cannot be googled.

How to get started with educational research

You have read the articles about chemistry education research in recent issues of聽Chem 13 News, and understand why it is important to chemistry teachers, but you may not know where to begin or how to fit it into an already demanding schedule. Here we present a continuum of ways high school teachers can get involved with education research from being consumers of the research and implementing new ideas in their classrooms to completing full-blown research studies where they develop interventions, collect and analyze data, and publish or present the results.

Why educational research matters to you: Parachutes, particles, bonding and 鈥済ood enough鈥� models

What does watching a parachuting team free-falling through the sky have to do with teaching the particle nature of matter to your elementary or middle school students, or with helping your secondary or first-year university-level students learn about structure and bonding?

Formal lab reports must die

Remember formal lab reports from your undergrad days? Multiple page affairs starting with an abstract, followed by an introduction, experimental,聽data, calculations and ending with the (dreaded) discussion. These reports did me a lot of good.

Why study chemistry?

I was inspired to start a regular feature in my chemistry class called "Why study chemistry?" after hearing Sam Kean, Brian Rohrig and Joe Schwarcz, featured presenters at the ChemEd 2013 conference in 蓝莓视频. As teachers, we would like to believe that our students remember everything that we teach them but, in reality, they will retain only a very small amount.

Getting to know you!

This year I decided to try a new "ice breaker" activity with my students to help get them interacting with each other on the first day. I handed out a 3x5 index card to each student in the class. The kids divided the card into four sections by making a line down the middle in both the x and y direction.

Learning styles: fact and fiction

When I first read about learning styles my wife, who received her B.Ed. in the 1980s, responded 鈥淎h, visual, auditory and kinaesthetic learning.鈥� Certainly, VAK (and VARK, VAKT, etc.) has been a staple of educational workshops and conferences at the school and post-secondary levels for decades. It is not alone: other entries under the 鈥渓earning styles鈥� umbrella include Dunn & Dunn鈥檚 model (stimuli & elements), Kolb鈥檚 Learning Style Inventory (convergent/divergent thinking) and, recently, Multiple Intelligences (MI).

Translating research into classroom practice

Peter Childs wrote an interesting article in Chemistry Education Research and Practice a few years ago on the topic of turning research into effective practice. In it he writes...

Unexpected misconception

When you have time, ask your students: 鈥淎re copper atoms brown?鈥�

So why the lack of chemists?

I keep reading in various science magazines the decreasing number of students entering science 鈥� especially chemistry and physics in North America. Since 1968 it seems that Canada has had a steady decline in interest in chemistry 鈥� basically since the new science curriculum was introduced to correspond with CHEM Study聽in the United States.

A little help from my friends

Phasing out the demo

I鈥檓 struggling to make peace with phasing out class demonstrations. I am in the middle of the transition from a traditional classroom into a student-centered learning environment.

What we can teach with hybrid orbitals

Chemistry has a method of making progress which is uniquely its own and which is not understood or appreciated by non-chemists. Our concepts are often ill-defined, our rules and principles full of exceptions, and our reasoning perilously near being circular. Nevertheless, combining every theoretical argument available, however shaky, with experiments of many kinds, chemists have built up one of the great intellectual domains of mankind and have acquired great power over nature, for good or ill. E. B. Wilson

Does teaching need changing?*

A woman visits her doctor, who has her enter his medical office. After several minutes of waiting she notices that the doctor has paid no attention to her, and that he is bent over his worksheets, on which he writes without pause. After a period of some impatience, the woman says to the doctor...

Microscale hints from across the pond

It was a great privilege to meet so many Canadian and American chemistry teachers and lecturers at the superbly run ChemEd 2013 conference at the University of 蓝莓视频. It was very brave of the organizers (and indeed myself for that matter) to organise a workshop over a 3,700 mile distance and a rather large stretch of water.

Chemistry explosions are all bang and no buck

I am a chemist and I am heavily involved in science outreach, especially in chemistry. I have built a library of demonstrations that I can pull out to show scientific principles.

Public enemy number one?

At a party recently, a friend of mine (or should I say ex-friend), notorious for his outspoken personality, ran towards me as I entered the room. Realizing that I was about to be accosted, I pretended that I had forgotten to plug in my car鈥檚 block heater, and tried to leave the room. 鈥淢ark鈥�.Mark鈥�.鈥�, I was trapped!
