ab: Summary: The author continues to explain the journey into algebra. It has
long been acknowledged that ‘understanding and using notation’ is
key to success in learning algebra. The experiences documented here
illustrate how this understanding can become a reality for most
learners. Not through some particular alchemy that is beyond
replication, but simply by using a well-researched, and crafted
software package. This learning media engages, challenges, and provides
students with feedback that undoubtedly influences their learning. As
you read, remember that the classroom and students described is
‘typical’, exhibiting all the residual features than have the
potential to influence the learning, in both a positive or negative
sense. So, what makes the difference here? For Part I see [the author,
ibid. 232, 21‒24 (2013; ME 2015f.01036)].
