Chemistry students around the world have written the Avogadro and Chem 13 News Exams, prepared by the late Dr. Carey Bissonnette for many years. Author: Michael P Jansen, Crescent School, Toronto, Ontario

Eventually . . .

Let me tell you a story. With any luck there will be a point. Author: Michael P Jansen, Crescent School, Toronto, Ontario

Student eye

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. Author: Michael P Jansen, Crescent School, Toronto, Ontario

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

I am the Head of Crescent School鈥檚 Science Department. Before you get all impressed by this lofty title and the attendant responsibilities, I鈥檒l toss a little full disclosure your way: no one else wanted it. Author: Michael P Jansen, Crescent School, Toronto, Ontario

The power of empirical evidence

As chemistry teachers, we have to explain things. Complicated things, with complicated explanations. Then, these complicated explanations work their way into our students鈥� brains. Author: Michael P Jansen, Crescent School, Toronto, Ontario

Adjusting study techniques

One of the biggest shocks that I experienced while starting university was having to alter my study techniques. During my first year, I began to realize that the study methods I used throughout high school were no longer working for me. Author: Natasha Evans, biochemistry student, University of 蓝莓视频, 蓝莓视频, Ontario

Open-book, collaborative quiz: Recipe for engagement

I鈥檝e written about incentivizing students as a way towards engagement. I recently hit upon a great idea 鈥� a real brain wave. AP Chemistry students completed a challenging lab where they carried out (and analyzed) a bunch of redox reactions.

My first undergrad chemistry exam

For many science students at the University of 蓝莓视频, their first exam experience comes in the form of what is known as 鈥淐hemistry Term Test 1鈥�. University chemistry is a fast-paced environment with little time to stop and catch up.

Make me an offer鈥�

Michael Jansen gives his approach to some of the struggles that face teachers.

Moving out and far far away

Lilli Temple-Murray describes her experiences and struggles moving away to go to university.

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�

I want to be a doctor

鈥淲ho wants to become a doctor鈥�? I remember sitting in my first year 鈥済et to know your program鈥� seminar and the professor asked that question to the thousand or so students. With hundreds of hands confirming the statement, she shattered everyone鈥檚 dream by saying 鈥渃ongratulations, only three of you will make it.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.

Once in a Blue Moon

The saying, 鈥淥nce in a Blue Moon鈥� refers to two full moons occurring within the same month, a rarity. This recently occurred this past January 2018. The actual moon appearing blue in color occurs from time to time as well.

One pearl of wisdom

I asked 1st and 2nd year University of 蓝莓视频 instructors for one nugget of wisdom to share with incoming students.

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�

The launch of Chem 13 News online publication

Fifty years ago Chem 13 News magazine started as a free newsletter published by the Chemistry Department at the University of 蓝莓视频 and now, with the help of high school teachers around the world, we are moving to publish material online with free access.

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.

Sig dig in undergrad labs (Part 1)

A few blocks from my home a parcel of land is for sale with a large sign advertising its size as 鈥�+/- 5.23 acres鈥�. Is it possible that I could purchase -5.23 acres of land? Would the seller then pay me for this purchase? Of course this is ridiculous, and we could logically assume the vendor isn鈥檛 selling negative acreage, and so interpret the sign to mean approximately 5.23 acres, but this lack of clarity is not acceptable in science.

Chemistry boldly goes to the edge

In my high-school studies, science disciplines were presented as fields of knowledge based on certainty and absolute truths. My chemistry teachers spent most of the class time solving mathematical problems to get quantitative results instead of exploring the meaning of the numerical results obtained.

How to be a good lab partner again

In a previous issue I shared some tips I learned on being a good lab partner in an undergraduate chemistry lab, and I would like to add more advice on how to be the best lab partner you can be.

Why not start a Chemistry Education Research Group?

In spite of everything that I don鈥檛 know about chemistry, which would fill a significant portion of the internet, I鈥檓 not a fan of being told how to teach.

Dry-erase markers 鈥� and the teachable moment

I just had the most wonderful Grade 11 Chemistry lesson that really took off in the final few minutes. The topic was an introduction to solubility 鈥� 鈥渓ike dissolves like鈥�.

How I prepare my students to write university exams鈥�

I wanted to comment on your "Midterms can be a shock" article from the December 2017/January 2018 issue since it was particularly applicable to what was happening in my two sections of Grade 12 University Advanced Functions.

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.

Joy of joys!

I know many of you will share my feelings of indescribable goodness when an experiment turns out super-well. Let me share . . .

Lab partners matter

In the chemistry undergraduate labs, you will eventually have to find a lab partner. This is the person who could make or break your 3-hour session every other week for the entire term.

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.

First day of classes 鈥� read your syllabus

The term feels long and full of potential on that first day of class. Whether it鈥檚 your first semester or your last one at university, always take the time to review your course syllabus, understand the course requirements, needed materials, break down of assignments, midterms and final exam.

What鈥檚 up with the bell?

A few years back, I got for my classroom a small bell, the kind that hotels have on the front desk that you 鈥渄ing鈥� for service.

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.

Midterms can be a shock

Most students worked hard to get into university and have been successful in high school 鈥� very successful. So why do midterms shock many of these capable students?

Good relationships

Let me tell you about Brandon. He didn鈥檛 have the greatest reputation coming out of grade 10: lacklustre engagement with an attitude to match. In Grade 11 Chemistry, it didn鈥檛 take long for me to see that his 鈥渞ep鈥� was well-earned.

Good communication is the key: email

At the University of 蓝莓视频 鈥� and most universities 鈥� individual concerns and questions can often be resolved quickly by email. In the Science Undergraduate Office we receive hundreds of emails each week. During peak times throughout the term, we receive hundreds of emails per day.

Lab safety & common sense 鈥� not mutually exclusive

It doesn鈥檛 matter how you feel鈥�

Those of you of a certain age will remember 鈥淔ernando鈥檚 Hideaway鈥�, a 鈥渂it鈥� that Billy Crystal did on Saturday Night Live. His celebrity interviews always included something like this: 鈥淚t doesn鈥檛 matter how you feel鈥� it鈥檚 how you look. And baby鈥� you look marvellous鈥�.

Think about the chemistry, not the math

I tell students on the first day in my undergraduate chemistry class 鈥� think about the chemistry, not the math. Almost every chemistry calculation problem can be deconstructed into a math word problem.

AP Chemistry survival

This is a favourite of the students' because of the wow factor.

Memories of a chemistry teacher

When people discover I鈥檓 a chemistry teacher, they feel compelled to tell me about their chemistry teacher.
