Many studies have shown the learning-by-teaching effect.Students who spend time teaching what they've learned show better understanding and ability to remember knowledge than students who simply spend the same time re-studying.But why does teaching help？
Researchers did a study to test their idea that teaching improves the teacher's learning because it forces the teacher to find back what they've learned.They asked 124 students to spend ten minutes studying a text with numbers on a topic which is completely new to them.They told the students they could take notes while studying，but would teach the material afterwards without notes.After studying the text，the students were divided into four groups.In one group the students spent five minutes giving a lesson on the study material without notes.The other groups either spent the same time completing arithmetic （算術） problems，teaching with a script （講稿） or writing down all they could remember from the text — a form of recalling practice.A week later，all the students took a surprise test of their knowledge and understanding of the text.
The important finding is that the teaching-without-notes group and the recalling-practice group performed better than the group that completed arithmetic problems and the group that taught with a script.
The researchers said the result shows that the benefits of the learning-by-teaching method are caused by recalling practice；that is，the learning by-teaching method works only when the teaching includes recalling the taught materials.
The new findings have a practical suggestion for how the learning-by-teaching method is used in education.In order to make sure that students learn and remember an educational material，they should internalize （內化） the material before presenting it to others，rather than depend on notes during the presentation process.

2．4 Apps to Enhance Distance Learning
Distance learning has become the new form of education since schools closed，and teachers have adapted – with the help of some truly amazing online applications.
Google Classroom
This popular application allows teachers to create online forums（論壇） to share courses，news，or lessons as well as a platform to assign，collect，and give feedback on student work.I've used Google Classroom for years，and it has become the cornerstone of my classroom throughout distance learning.
Google Forms
This application is often used to gather information in a variety of contexts（surveys，tests，etc.）.Its test feature can be enabled to block users from opening other windows.It also offers auto-grading for multiple-choice tests.It has become a daily application in my classes during distance learning.I use it for pre-assessments，tests，and surveys.
Flipgrid
Flipgrid is a free online application that allows students and teachers to record short online videos.Teachers can easily create accounts and then within accounts create "classrooms." From there，teachers can create posts for students to respond to via（通過） short videos.
Google Meet
Google Meet is an online meeting platform where teachers can share their screens with all participants to see as well as record the meeting.I've recorded all of my daily lessons and then posted the recordings to Google Classroom at the request of my students.This is a practice I'd like to continue even after distance learning as students really like the option to return to a recording of the day's lesson to review it at their own pace.
