MathsWatch is the complete online Maths platform that makes learning available to your students 24/7 from anywhere in the world.
The pedagogical analysis covers how the product supports learning of the identified skills. The student’s role is assessed by four contrary pair parameters, which are selected to cover the most essential aspects on the use of the product.
The following are the high educational quality aspects in this product.
Very informative and wide selection of both material and tasks
Easy to follow, and high quality evaluation tools for the teacher
The videos were nice and easy to understand.
The supported learning goals are identified by matching the product with several relevant curricula descriptions on this subject area. The soft skills are definitions of learning goals most relevant for the 21st century. They are formed by taking a reference from different definitions of 21st century skills and Finnish curriculum.
