Dear Maria,

"computer based environment" is a quite broad term.

I may now point out a few terms you could further on investigate. Blended learning, flipped classroom, web-based virtual environments, etc. Other ways could be a use of combinations of traditional and digital teaching and learning tools in a single environment. You could use the instrumental genesis theoretical framework for investigating students learning in a Dynamic Geometry Environment. You may use design based research as well. For an example see:

https://www.researchgate.net/publication/281399561_Conceptual_Understanding_of_Dot_Product_of_Vectors_in_a_Dynamic_Geometry_Environment

Maybe some of the references in the article will give you additional ideas.

Best wishes,

Ana

Hola, no se si tu campo de interés sean la educación matemática, pero este es un buen libro sobre el uso de calculadoras en la clase de matemáticas: The Didactical Challenge of Symbolic Calculators. Es de editorial Spriger Verlag. http://www.springer.com/us/book/9780387231587

Dear Maria!

You can have a look at chapters or papers by Roger Azevedo (MetaTutor), Susanne Lajoie (BioWorld), Maria Bannert, Gautam Biswas (Betty's Brain), and James Lester (Crystal Island). All these researchers have computer based learning environments, and they all study learning strategies in their respective systems. These will give you a pretty good idea to narrow down your question.

Hypermedia materials are multiple  nodes  containing  various media forms such as text, sound, graphics and movies either individually or combined, enabling users to move from one node to another at will, accessing information from nodes that are more associative and are delivered in a non-linear sequence, allowing the learner greater control and interactivity

I suggest you have a look at the book "e-learning and the science of instruction: proven guidelines for consumers and designers of multimedia learning" second edition by Ruth Coilvin Clark and Richrad R. Mayer, published by Pfeiffer, an imprint of Wiley.The content of the book and suggested readings at the end of each chapter should satisfy what you are looking for.

 I do not know if you are interested in language learning strategies, but, if so, you might want to have a look at this:

I recommend having a look a this classic study: Pask, G. and Scott, B. (1973). "CASTE: a system for exhibiting learning strategies and regulating uncertainty", Int. J. Man-Machine Studies, 5, pp. 17-52.  You can then get more up to date with this book: Ford, N. (2008). “Web-Based Learning through Educational Informatics”. Information Science Publishing, Hershey, PA.

Thank you for your help!!!

Best wishes,

María

I agree with Bernard Scott
