Bells and whistles aplenty... but what is the impact?

Note: This post is in response to Week 3 Module 3 Blog 2

There are many ways of introducing a technology for use in the classroom. This can range from an interested teacher introducing a technology to a classroom simply because it is the latest “cool thing” they own (e.g. a 3D printer or Lego robot), the introduction of technology simply because it is more flexible (e.g. Interactive White Boards (IWBs) vs blackboards and overhead projectors) to adopting a technology school, state or nation-wide based on research.

Ultimately there is usually some sort of process involved. One concept to evaluate technology is to look at the “affordances” the technology offers. This simply means looking at what the technology can do based on its particular features. There have been attempts to make frameworks to make this somewhat of an objective process – breaking a system down into features such as read- or watch-ability, search-ability, integrate-ability, share-ability (too many to list here) as well as basic features such as ease of use, appear and reliability (Bower, 2008). Whilst this process may serve to highlight affordances not previously recognised, a problem is that the interactions between affordances and the details of how they work are not considered and this can ultimately change the learning experience (Bower, 2008). It is a little like the advent of nutrition-ism in food – we can break a food down into its components and identify the nutrients but the form of the food and the manner with which it is consumed makes a difference to the way our bodies process and react to it (Pollan, 2008).

So, if breaking down a technology into its affordances is potentially flawed then how do we decide which technologies to use? Certainly looking closely at the features offered is valuable. Another measure may be to look carefully at the impact of the technology. What changes (positive or negative) could it make to outcomes – for the student, the teacher, the school or even beyond? (Kozma, 2005). Interestingly, research backing is not always high on the list of priorities for teachers or schools in choosing technology, possibly due to the research cycle being outrun by technology development (Kennedy, 2017). How then do we determine impact?

Calculators - the future or the past?


Note: This post is in response to Week 3 Module 3 Blog 1

This week we’re looking at a variety of hardware and software technologies for use in the classroom. I’ve chosen a Texas Instruments TX-Nspire CX-CAS calculator which I’m learning to use for my own studies.

CAS stands for Computer Algebra Software which allows programming of complex operations with the calculator. There are many resources available for the classroom use of this calculator, including class sets, networking hardware, teacher software and charging stations (see https://education.ti.com/en/products?category=ti-nspire-technology ), not to mention online teaching resources, some specifically for Australia (e.g. http://compasstech.com.au/nsw/index.html ).

One of the limits of using such hardware are the rules around their use for assessments. The current NSW HSC does not allow this type of calculator, although I note that the Victorian VCE does. The Australian Curriculum (Australian Curriculum Assessment and Reporting Authority [ACARA], n.d.) does not yet specify approved calculators, however it does indicate in the ICT capabilities that CAS can engage students and promote understanding (ACARA, n.d.). These rules mean that although the average smartphone has more processing power, memory and storage than the calculator, calculators are still developed specifically for use in mathematics classrooms (alongside software and apps which have similar capabilities).

The use of CAS in the classroom can enable students to solve problems outside of their pen and paper skills and to be more willing to attempt unfamiliar problems (Cameron & Ball, 2015). To really take advantage of this though, we need to shift the focus to teaching competencies which complement the work of computers rather than compete with it (Gravemeijer, Stephan, Julie, Lin, & Ohtani, 2017)

I wonder whether we will reach a point where the use of smartphones/internet/computers becomes a non-issue and the curriculum is truly adjusted to cater for this? I know from my own experience that simply having a calculator which can do complex calculations is not enough – in the end we need a level of conceptual understanding to be able to ask the right question, enter the right calculations, analyse and break down the problem (Gravemeijer et al., 2017). Will students lose the capability of doing these calculations manually, or with a “standard” scientific calculator? Perhaps, but is that a problem? Could stand alone calculators ultimately go the way of the abacus or the slide rule?
