The pandemic turned VCE Chemistry upside-down. Stoichiometry, traditionally a difficult topic, was the best-answered of all. Chromatography, traditionally an easy topic, was the most difficult for the class of 2020.
Most noticeable is the increase in “difficult” topics highlighted red in the chart above. (For a comparison with the 2013 & 2014 VCE Chemistry written examinations, click here.)
Unbelievably, the Victorian state average score in the 2020 VCE Chemistry written examination was a FAIL at just 47.9%.
Disruptions to learning caused by the pandemic could help explain why the VCAA is considering making the VCE Chemistry curriculum substantially easier from 2023 onwards. If the educational effects of the 2020 pandemic really do linger for most of this decade then making the curriculum easier fails to tackle the root of the problem, which is the loss of quality study-hours. I believe the only correct remedy is to provide current students with extra training and support to make up for the pandemic… not to drop the bar so low that our students cannot compete on the world stage.
This chart shows the percentage of students with a top 100 Asian surname among high-achieving VCE students (≥2 study scores ≥40) by subject with EAL students excluded from the analysis.
The proportion of high-achievers with Asian surnames was highest in the following subjects: Specialist Maths, Maths Methods, Physics, Chemistry, Accounting and English Language. Conversely, the least Asian subjects among high-achievers were Drama, Sociology and Theatre Studies.
All spelling variations of the top 100 Asian surnames listed on Wikipedia were included in the analysis, for example Li as well as Lee.
Directory of best teaching methods. A logical, concise teacher’s bible.

The Project for Enhancing Effective Learning (PEEL) was founded in 1985 by a group of teachers and academics who shared concerns about the prevalence of passive, unreflective, dependent student learning, even in apparently successful lessons. They set out to research classroom approaches that would stimulate and support student learning that was more informed, purposeful, intellectually active, independent and metacognitive. The project was unfunded and not a result of any system or institution-level initiative. PEEL teachers agree to meet on a regular basis, in their own time, to share and analyse experiences, ideas and new practices.
PEEL has evolved into a global education reform movement with supporters in most developed countries. Its creed, pooled from teachers (not theorists or politicians), has been expanded into an abundance of numbered lists: “the 6 PEEL goals”, “the 10 journeys of change” and “the 12 PEEL teaching practices”.
Fortunately, their main text, Teaching for Effective Learning, is still a practical teaching guide with maximal classroom significance. I’ve already used many of the methods in this book in my own classes, and decided to give my own views here on how effective they all are.
From my 3 years’ teaching experience, here’s my list of favourites (with star ratings)…
A1: Concept mapping (basically character mapping). I love this method and use it myself. Interestingly, PEEL tells you to extend it by including characters, themes and objects in the map (which would be very complicated). ★★★★★
A2: Concept grids (basically tables). Seldom applicable, but useful when they are. ★★★★
A3: What’s my rule? This works better the other way around. Put two headings no the board and ask for differences and similarities from the class to stimulate discussion. Also a form of diagnostic (preliminary) testing. ★★★★
A7, A8, A9 and A10 (and to some extent A26) are ‘translation’ activities, in which your subject of instruction (e.g. Chemistry) is translated into another (English, Drama, Art and Media, respectively). “Write a story about an apple being digested…/ Make a poster that advertises a plant of your choice”. These are time-consuming because students generally aren’t used to linking subjects together, but are fun and students learn a lot from sharing their work in front of the whole class. ★★★★★
A12: Brainstorming. Small groups (individuals or pairs) results in greater participation per student. Ask open questions, let students brainstorm the answers. ★★★★★
A16: Cloze exercises. Choose a new text and use software to automatically replace every (usually 7th) word with a blank space. Ask the students to fill in the blanks. Research shows that cloze exercises are a reliable (formative) test for reading comprehension level. ★★★★
A18 and A29 combine to form a “Reading Process”, or a form of active reading. Highlighting characters, underlining new words, and summarizing each paragraph are standard practices for improving reading comprehension. (They are scaffold techniques, which can be mostly abandoned later, or evolved into more natural forms of note taking). ★★★★★ (as a “Reading Process”)
A25: Silent class. Do this sometimes! Tell the students they’re going to spend the entire class reading in silence. When you read attentively and visibly and silently, making notes, the students will start to imitate you. You can’t do this often, but done occasionally, it improves discipline and independent study habits. ★★★★★
A34: Whole-class simulations. Works well for enacting historical events, which are relevant in almost all subjects. Memorable, but can’t be done too often. Requires planning. ★★★★★
B1: Predict-Observe-Explain. Central to science education. ★★★★★
B3 and B7 are types of assisted discussions. This should be standard practice in all classes where group discussion is allowed. Always facilitate and mediate students’ discussions by walking around the room and talking to all the groups. Scope for group-work is limited in Chemistry, though. Pairs work best. ★★★★★
B8: Probe prior views. Diagnostic testing (a.k.a. preliminary testing) should always be done before a unit is taught. Use A3, A12 or simple question-and-answer as a whole class to probe prior views. ★★★★
B19: Complete statements from a stem. “A paragraph is…” makes both a good start-of-class quiz, and a good summative testing technique. ★★★★★
B28: Buzan® mind mapping should be compulsory education. ★★★★★
I excluded three types of PEEL techniques:
First, I’m not a fan of gimmicks. The ‘Y-chart’, the ‘thought balloon’, and the ‘postbox’ method (a bizarre secret-ballot-brainstorm combination) were among the ‘gimmicks’ that I omitted from the list.
Second, I’m also not a fan of non-educational classroom games. “the 5/3 method”, “brainstorm bingo” and “circuses” might make kids happy but won’t teach them enough to justify the commotion.
Finally, some quality PEEL methods were only suitable for primary schools. ‘Mingle/match/mate”, “guess the picture”, A19 and A20 were some of those.
The ones in this list are the best of the rest—the ones I’ll use as a secondary school chemistry teacher.
This book is relevant for every teacher: primary and secondary, sciences and arts, both high and low ability streams. I’ll be referring to this bible when planning my own lessons as a constant reminder to diversify my teaching style and keep my classes interesting. ★★★★★
