Decoding John Hattie's Visible Learning: Strategies That Make a Difference

For educators and those deeply involved in the world of pedagogy, John Hattie's name resonates as a beacon of research and enlightenment. Renowned for his groundbreaking books, "Visible Learning" and "Visible Learning for Teachers", Hattie's contributions have reshaped our understanding of effective teaching strategies.

What is Effect Size?

At the heart of Hattie's research is the concept of the "effect size." It's a metric designed to quantify the impact or influence of a particular strategy on student learning outcomes. To compute the Effect Size, one subtracts the mean score of a group exposed to a specific strategy from the mean score of a control group. This difference is then divided by the standard deviation. The resulting value provides a measurable insight into the strategy's effectiveness.

Here's a quick breakdown of the Effect Size scale:

- Small Impact: An effect size of +0.20

- Medium Impact: An effect size of +0.50

- Large Impact: An effect size of +0.80 or greater

Noteworthy Strategies from Hattie's Latest Rankings:

Delving into the latest Hattie ranking, a few strategies caught my attention during recent walkthroughs. These strategies aren't just theoretical; they have tangible impacts that educators can witness and integrate into their classrooms.

1. Strategy to Integrate with Prior Knowledge (+0.93): Leveraging students' prior knowledge is a potent tool. When new information connects with what students already know, retention and comprehension soar.

2. Classroom Discussions (+0.82): Encouraging open dialogue and fostering an environment where students can voice their opinions and questions can significantly enhance learning.

3. Feedback (+0.70): Feedback, when provided constructively and timely, acts as a guiding light for students. It offers insights into areas of improvement and reinforces positive learning behaviors.

4. Direct Instruction (+0.60): Sometimes, the traditional approach stands the test of time. Direct instruction, when done effectively, remains a valuable strategy in the educator's toolkit.
