Tools and Environment

I have been thinking over the past week about tools and environments for online learning. In reviewing my Purpose and Problem statements on my dissertation I find the word tool in the title:

LEARNING IN ONLINE INSTRUCTION: A QUALITATIVE
STUDY OF UNDERGRADUATE
STUDENTS’ USE OF
ONLINE TOOLS

But in all my discussion I use things like environment and interactions. In interviews students use terms like resources, communication, challenge, and other more general descriptions.

My question is what is a learning environment if it does not include the tools in the description? and can I use the term environment to describe online learning?

Changing the title to something like:

LEARNING IN ONLINE INSTRUCTION: A QUALITATIVE
STUDY OF STUDENTS’ Perceptions and use
of Online Learning
Environments
