AI and programming classes in the Northern Beaches

Where can Northern Beaches students find the best online AI and programming classes?

In small live online groups where a teacher builds and tests real models with the class, from Scratch for young children to Python machine learning for teenagers and adults. The 2021 Census counted 263,554 residents in the Northern Beaches council area, and 36,150 families, 49.9%, were couples with children.

Median age changes a lot along the peninsula: 49 around Bayview and Elanora Heights, 36 in the northern part of Dee Why. A simple model can guess an area's median age from the areas next to it. The interesting question is how to test that guess honestly, because nearby areas share so much that a careless test lets the answer leak in.

In the August 2021 lockdown, 59,959 employed residents, 44.0%, worked from home on Census day.

Driving to work

44,891 workers, 33.0%, drove to work that day, compared with 43.1% across the state.

Professionals

41,531 working residents, 30.5%, were employed as professionals.

Census figures are lightly adjusted by the bureau to protect privacy, so the 19 smaller areas below are shown one by one and never added up to make a council total.

Signature project

Can neighbours predict an area's median age?

The council contains 19 statistical areas (SA2s). For each one we took the median age published in QuickStats and an approximate centre point, then asked a three-neighbour model to guess each median age from the three closest other areas.

Random folds

Hold out areas at random and a test area usually still has its next-door neighbours in the training data, so the model looks strong.

Block folds

Hold out a whole stretch of the peninsula, such as Avalon to Terrey Hills, and the model must guess from areas further away. The error rises to 2.72 years.

Still useful

Even with blocks, the neighbour model beats simply guessing the average of the other areas, 2.72 years against 3.93.

The result that did not hold

Cut the peninsula into five blocks instead of four and the gap disappears: 2.19 years both ways. Use one neighbour instead of three and blocks score better than random folds. With only 19 areas, the choice of split moves the score as much as the model does.

The model, the blocks and the error figures are our own work; the median ages are published ABS values printed exactly. The lesson is about how to measure, not a claim about why ages differ along the coast.

Inside the model

What students write, in four steps

The whole project is short enough for a teenager to write in a few lessons, and each step teaches a habit that carries over to bigger machine learning work.

The pieces of the peninsula project
StepWhat the code doesHabit it builds
DistanceMeasures kilometres between area centres on a sphereUsing the right distance for the data
GuessAverages the median ages of the nearest areasStarting from a simple, explainable model
SplitBuilds random folds and north-to-south blocksAsking whether test data is truly unseen
RepeatReruns the random split 200 timesReporting a range, not one lucky number

The same caution applies far beyond maps. Readings taken minutes apart, photos of the same person, or sales from the same shop all leak information between training and test data if they are split at random.

Younger learners

Play a guessing game on a map: can you guess a beach's temperature from the beaches beside it, and is it fair if you peeked?

Teenagers

Code the model, the folds and the baseline, then write a short note on which score to believe and why.

Adults

Apply grouped and time-based splits to work data before trusting any accuracy figure.

Manly Village Public School records its first teacher in 1858, followed by Seaforth Public School in 1881 and Brookvale Public School in 1887.

Term 1, 2027

Eastern division schools start Term 1 of 2027 on Wednesday 3 February and finish it on Friday 9 April.

Areas, not suburbs

The 19 statistical areas are ABS units that often join two suburbs, such as Collaroy and Collaroy Plateau. The council headline figures cover all of them.

Coding and AI

If AI tools can train a model in seconds, what is left for a Northern Beaches student to learn?

Judging the result. Training is now the easy part; knowing whether a score means anything is the skill.

Ask an AI assistant for a model and a cross-validation score and it will usually split the data at random, because that is the default. On data with a map, a calendar or repeated people in it, that default can report a model as better than it is, and the code will run without a single warning.

A student who has watched the peninsula error move from 2.23 to 2.72 years just by changing the split knows to ask how the test was built. That question is what employers and universities want from people who work with AI.

The student who questions the split is the one who can be trusted with the model. The longer argument is in why teenagers should still learn to code in 2026.

Fees for Northern Beaches learners

Three figures, and nothing hidden.

First classUSD 0

The first class is free and finishes with an honest course suggestion.

Group tuitionUSD 100

One month of group classes, normally eight, with fifteen to twenty learners of a similar level.

Private tuitionUSD 150

FAQ

Northern Beaches AI and programming questions

Questions Northern Beaches parents and learners often ask.

How many people live in the Northern Beaches council area?

The 2021 Census QuickStats for the Northern Beaches local government area record 263,554 residents, a median age of 41 and 105,017 private dwellings.

What is cross-validation?

It is a way to test a model by hiding part of the data, training on the rest and checking the guesses, then repeating with a different part hidden. The final score is the average across all the rounds.

Why split the peninsula into blocks?

Because next-door areas are alike. If a test area's neighbours stay in the training data, the model gets help it would not have on genuinely new places. Blocks remove that help.

What did the Northern Beaches project find?

With four folds and three neighbours, random splits gave an average error of 2.23 years and north-to-south blocks gave 2.72. With five blocks the difference vanished, which is itself the lesson: 19 areas are too few for one score to settle anything.

Is AI suitable for primary school children?

Yes, through games about patterns and prediction in Scratch. Python machine learning usually starts around 12 to 13.

Do you teach Copilot Studio agents?

Yes, one to one only. Group classes build agents in Python instead.

Do you have a centre on the Northern Beaches?

No. All lessons are live online, we have no premises in Australia, and the phone number we show is an Indian number.

How much do classes cost for Northern Beaches learners?

The first lesson is free. After that, group lessons cost USD 100 a month for two live lessons a week, about eight a month, with fifteen to twenty learners, or USD 150 a month one to one. Course, format and time are agreed before payment.

How big are the groups?

Fifteen to twenty learners, matched by level, pace and goals rather than age or suburb. One-to-one lessons are offered if no group suits the learner's time.

Can adults join?

Yes. Adults study in adult groups or one to one, often aiming at data or AI tasks in their current job.
