Benjamin Bloom’s 1984 paper showed that one-on-one tutoring could lift student achievement by two standard deviations, meaning the average student could perform as well as the top 2%.
He proved that improved learning is possible.
The problem?
We can’t give every student a personal tutor…
OR can we?
It’s way too expensive. Right!
But digital tutors are offer the answer.
Back in 2014, a study by the Institute for Defense Analyses (IDA) for the U.S. Navy, “Accelerating Development of Expertise: A Digital Tutor for Navy Technical Training”, revealed something extraordinary.
Sailors with no prior IT experience achieved higher scores in technical knowledge and troubleshooting after just 16 weeks with a digital tutor than peers who completed 35 weeks of classroom instruction — and even outperformed technicians with nine years of fleet experience (Hsieh et al., 2014).
That was over a decade ago.
Today, AI & modern learning platforms can go even further, solving Bloom’s Two-Sigma Problem while lowering the cost of education & boosting engagement and motivation.

Spaced repetition has long been a favourite of education departments and is embedded in most curricula.
Reviewing the same information repeatedly can be a pretty boring process, however, apps and AI offer a SOLUTION.
If we embed the idea into Apps that are easy and fun to use, we can increase the spaced repetition almost invisibly.

Tests can be DROPPED altogether.
Data from apps can be used to track student learning.
Time taken in testing is not teaching.
Many schools do a pretest in week 1 of a term and an assessment test in week 10, leaving only 8 weeks for teaching instead of 10.
No kid comes to school because they love tests.

Learning apps improve learning and scale well. The problem is many of them are boring and fact-based.
However, game-based apps can provide explicit learning in reading, maths, geography and history and problem-solving.
Best of all kids receive immediate feedback and on-the-spot tuition.
There is no problem with focus as kids who are playing games are totally absorbed.
We need more games in education.
What are these good for? – For learning basic skills that require repetition and reinforcement. For providing ongoing assessment of student progress. As well as for developing imagination, tinkering skills, creativity, persistence, thinking, problem-solving, and resilience.

Apps make it easy to build datasets for learning.
It is possible for every kid to have their own learning profile.
Students could access the data to see their own learner profiles.
For teachers, gaps in student learning would be easier to see.
Leading to a personalised experience for each student.

Never before have we had SUCH ACCESS to information.
Kids can research and learn about anything they want to.
There are videos and information on every possible topic.
In this age of the internet, information is easily accessed and the drive to self-educate should be the educational goal.
Unfortunately, most schools train students to be compliant rather than curious.
Students are not encouraged to follow their own interests and passions at school, but to follow the herd in both content and pace. Being a docile passive student is the outcome.
Using apps to cover essentials like mathematics, reading, and writing can make fundamentals fun and provide detailed data to assess learning.
No kid should see learning as boring EVER.

When they have agency and choose the things they love to do. When, what they do matters to them.
When they have an audience of more than one person for their work.
When they are curious and excited about learning.
The majority of students are disengaged by the final years of Primary school. School should be Absolutely Splendid.
I learn the most from creative inspiring projects, projects I want to learn about, topics I chose to work on, and tasks I struggled with and had to figure stuff out for myself
AND SO DO KIDS.
Bored students learn less!
