Despite occasional bursts of rhetoric about developing that mysterious beast ‘the world class workforce’, the goal of most education ministers turns out to be beating Singapore or Finland in the tables of PISA, the Program for International Student Assessment: in other words, to keep racking up the test scores, without stopping to think what those scores are meant to indicate. Examination results are proxies for our underlying values and intentions, not ends in themselves. Most of what kids learn in school they forget within weeks of having taken the test. As Einstein said, ‘Education is what remains after you have forgotten everything you learnt in school.’ So what are the valuable residues which we want for all our young people after those 12 long years in school? 

The research consistently showed that students taught through PBL displayed:

• enhanced student performance
• increased student motivation and engagement
• improved teacher/student interaction
• Increased development of 4 C’s of 21st Century Learning: creativity, critical thinking, collaboration, and communication.

A communal and flexible learn­ing area known as The Hub takes the place of stand-alone class­ rooms and children are grouped according to their stage of learning rather than age. 

For teachers to be able to regularly evaluate their impact in the classroom and adjust their teaching methodology in response to what they see, the classroom needs to be made visible. The concept of seeing clearly what teachers are teaching and what students are learning is known as Visible Learning.
