The Hattie study suggests that school grades are not a reliable indicator of academic success. The study found that there is a weak correlation between grades and actual learning, with many students achieving high grades without truly understanding the material. This indicates that grades may not accurately reflect a student's knowledge and skills, and that other factors such as effort, motivation, and study habits play a significant role in academic success. Therefore, the study suggests that educators should consider a more holistic approach to assessing student learning and progress. **

Qi energy is not inherently energy-saving in the traditional sense. It is a concept in traditional Chinese medicine and martial arts that refers to the vital energy or life force that flows through the body. While practices such as qigong and tai chi, which aim to cultivate and balance Qi, may promote overall health and well-being, they are not specifically designed to save energy in the way we typically think of it in terms of electricity or fuel consumption. However, the principles of Qi cultivation may lead to a more balanced and efficient use of personal energy and resources. **

Both Yoga and Qi Gong have been shown to have positive effects on the psyche.

Ultimately, the choice between Yoga and Qi Gong depends on individual preferences and needs, as both practices offer unique benefits for the psyche. **
