Methods and trends

First, What is blended learning? 

It is learning that combines e-learning (synchronous encounters) with face-to-face (synchronous) encounters taking the advantages of both types of learning. 

And the reason why is is sucesfull is because  More and more education establishments are coming to rely on the blended learning model. Their reasoning is simple: a multichannel teaching method offers the best of classroom and online learning all in one place.

Each student has a range of different strengths and requirements and a blended learning approach allows tutors to acknowledge this. When they are given the ability to use tools from both traditional and digital spheres, tutors are able to present necessary information in a range of different ways designed to suit the varying learning styles of their students.

The next on is  Project Based Learning. Project-based learning is a dynamic classroom approach in which students actively explore real-world problems and challenges and acquire a deeper knowledge.
Students learn how to solve problems that are important to them, including real community issues, more effectively, even learning from failure and possibly starting over. Relationships formed during collaboration is a huge part of PBL. Not only do students learn how to work better in groups, providing their own input, listening to others, and resolving conflicts when they arise—they build positive relationships with teachers, which reinforces how great learning is. Students also form relationships with community members when working on projects, gaining insight for careers and beyond.

The last one is Task based learning. is a TESOL approach that has roots in the Communicative Language Teaching method, where the teaching process is done entirely through communicative tasks. 

 As with any other skill-learning process, students fall on a “risk-aversion continuum”: when confronted with a foreign language, some will dive straight in, while others want to be as accurate as possible when speaking. The latter group uses different strategies to communicate effectively, for example, gestures, descriptions, synonyms, and through practice they gather more language items they can use in the future. Task-based learning helps students do this because it forces them to do something in class that they would do (and probably have done!) in in their own language.
