Barriers to the effective use of technology in education

Although technology is clearly making an impact on the way we learn and teach (Edwards, 2012), there are a number of barriers that teachers and students alike face when introducing technology into their everyday education. Whilst most educators realise the potential for success introducing technologies offers, such as the development of collaborative learning (Luckin, 2010) and learning anywhere at any time (Chuang, 2009), they must also be aware of the limitations to using technology just because it is available.



One of the most obvious problems with technology is the possibility that they will not work. Most technology relies on the use of digital networks, or the internet, therefore if there is a problem with either the technology will cease to operate (Edwards, 2012). Digital networks are prone to technical failure and this can have a massive impact on teaching and learning.



Ramey (2012) has proposed that lack of professional development is a major barrier to using technology effectively in education. Whilst many students are more than adequate in using recent innovative technologies for their personal use, there is still a limitation in that merely introducing the use of technology into the classroom will not lead to collaborative learning (Luckin, 2010). Teachers require sufficient training and support for using and implementing these technologies before learning can change. Shim and Shim (2001) also agree that simply providing the tools for change will not correspond to change; faculty members require considerable training to be able to support themselves and their students when using technology in the classroom. In addition to this, Johnson (1997) has identified that some teachers are not happy with changing their teaching styles to incorporate new technologies. Many feel that technology diminishes their role as teachers therefore are opposed to begin applying the current changes in society in relation to technology and learning.

Integrating new technologies into teaching is rarely an easy task. Technology has the right to be included in education as long as it is appropriate for enhancing learning (Lawrence and Lentle-Keenan, 2013); however research has shown that many students are comfortable with the amount of technology that is already being used in learning environments. According to Luckin (2009) up to 78% of students think that using PowerPoint presentations is very important in schools, and that changing these traditional ways of teaching has the ability to obstruct the learning process. Goodman (2001) also implies that students are ultimately responsible for their own learning; the introduction of technology may do very little to help the learning process. Using technology can be a barrier to learning in itself if it is only used because it is available, not because it is appropriate for the teaching style or to enhance educational roles.

A final barrier to the effective use of technology in education has been highlighted by Luckin et al. (2009). Collaborative learning is seen as one of the most important introductions to education and the introduction of Web 2.0 aids the collaborative process. However, when being assessed, students may struggle to differentiate between the mediums of collaborative learning and individual learning. Students are subject to restrictive assessments procedures that require separate submissions of personal work. This barrier needs to be overcome by succinctly clarifying the extent to which collaborative learning can be incorporated into classrooms, and even outside of class on homework tasks.

In conclusion, there are many advantages and just as many barriers to using technology effectively in education. It seems to be down to individual discretion as educators to decide what technologies will be effective, and what are simply being introduced into the classroom because the idea sounds good. In current society, it seems that the advantages of using current technology most definitely outweigh the limitations. However, it may need to be recognised that barriers to using these technologies effectively within education can be seen at an individual level (the teachers preference) an institutional level (insufficient training or support), or a technical level (technical failure).

Micro Teach Two

On November 1st 2013 I delivered my second micro teach to my peer group. The purpose of this micro teach was to remove the reliance of PowerPoint presentations in delivering information to the class. I was a little apprehensive when I first realised that I would not be able to use PowerPoint as this would typically be my preferred method for delivering Psychology lectures. However, I quickly realised that the one thing I believe I'm very good at within Psychology is research. Therefore I decided I would base my second micro teach around the introduction of a programme that can be used for setting up experiments for research; Superlab 4.0.

Although I wasn't unconfident in my knowledge of how to use Superlab, I was slightly anxious that I wouldn't be able to break down the information to correctly explain the basics of Superlab that would be relevant for incorporating into any experiment.

When I arrived at university on the morning, the whole network was down! I couldn't even log on to the university computers! I started to panic as my whole micro teach circulated around technology and using the computers. I actually thanked my obsession for always having to arrive at any destination early as I was able to spend ten minutes trying to log on to each of the computers I planned to use myself instead of the students trying to do this when they arrived at 9am.

The same as my previous micro teach, I started the session feeling quite nervous. Upon reflection, I now know that I need to prepare contingency plans for any session that relies on technology; its not as reliable as people make out! I believe this micro teach went as well as I would have liked it to under the circumstances; me being flustered about the possibility of the computers crashing at any moment and having only half a class of students. I think the main criticism of my micro teach was that I didn't ask enough questions and I didn't interact enough with the students to gauge their understanding of this complex programme. This is definitely something I need to work on as I struggle sometimes with the conflict between letting people work uninterrupted and making sure that the reason they are working quietly isn't because they simply don't get anything I have explained!

Observation week at UWTSD, Swansea.

My placement for the duration of my PCET course will be at University of Wales Trinity St David, Swansea. I arrived to meet Ceri on Monday morning at the university feeling excited. During this first week of my placement I was to be observing Ceri and Paul as lecturers; something I thought would be a doddle considering I have been watching them at work for the last three years! I was provided with a timetable for all the lectures Ceri thought would be worthwhile me observing, and any other duties I was to tackle whilst I was there.

Monday

I spent Monday morning observing the abnormal psychology lectures and seminars. I had only completed that module a year ago myself and I had been incredibly interested in it, so I found myself slipping back into the mode of a student and taking notes just the same as everyone else! I momentarily forgot that I was observing Ceri as a lecturer, and that I was supposed to be making notes of how she delivers her material not what she is delivering!

During Monday afternoon I got to observe a year 1 lecture and seminars. Paul was the leader of the module and I began to realised that his method of delivery and the way he teaches is not unlike the way Ceri teaches; however the difference between the material that is delivered at year 3 is incredibly different to the material that is delivered at year 1! I didn't realise the scope of information that these lecturers had to deliver at such different levels.

Tuesday

Today I observed the year 2 individual differences in the workplace lecture and three seminars. This is a module Ceri was hoping I would get highly involved with during my first term of placement due to the research and statistics nature of the assessment. Ceri provided me with all the information I could possibly think of to do with this module; week-by-week seminar schedules, the assignment proforma and additional information, and additional reading lists just in case I wanted to research anything myself! Handy!

Tuesday afternoon was again spent observing Paul at work in the research methods and statistics lecture for the first years. Just the same as the individual differences module, Ceri had hoped that this would be another module I would be heavily involved with as it will be focusing on introducing SPSS to the students when I return for my first week of placement.

Wednesday

Today I observed a number of other lectures, but I also had the chance to participate in my very first teaching position! Ceri had asked me earlier in the week if I would be willing to lead a session with a small group of third year dissertation students on the subject of Superlab; a programme I used for setting up my experiment for my dissertation. I was excited at the thought of teaching a group of students who (hopefully!) wanted to learn the material I would be delivering, but that excitement was far overshadowed by my nerves! My biggest worry was that the students wouldn't want a recent graduate 'teaching' them. After the session, however, I started to feel a bit foolish for worrying as much as I did! I realised that, if I had been in the position, I'd have been happy for the extra guidance on a new programme from someone who had experience with it. It did take a student to tell me this to realise though!!

Thursday

Today I got to accompany Ceri to Cardiff for two things; first, we attended a Tenovus conference at the Swalec Stadium, and during the afternoon I observed Ceri teaching a Masters Genetics Counselling class at Cardiff University. Even though waking up at 6am almost gave me heart failure (we had to be in Cardiff by 8.30!), I thoroughly enjoyed the whole day. I got to have a taster of the work that Ceri is most passionate about (other than lecturing). As a chartered health psychologist, she works on a lot of research projects involving genetic testing. Tenovus had funded her proposal to create a virtual online counselling environment for young people who either had cancer, or were carers for a family member who had cancer. It was incredible to see psychologists from all over England and Wales at the conference, and I got to sit in on talks by some very highly regarded researchers!

It was refreshing to see the other side of what it is to be a lecturer; a realisation that even lecturers have lives beyond their lecture halls and office walls! It is evidently clear that Ceri is passionate about the subject she teaches, and that is reflected in every lecture she gives; be it to her first, second or third years at UWTSD, or a Masters Genetics Counselling class at Cardiff University! I can only hope that in the future I exhibit the level of enthusiasm for my work that she does.

Friday

On Friday I got the opportunity to sit in on a meeting with the entire Psychology team regarding the validation of the new Single Honours Psychology programme they are hoping to develop. Again, this was another different side to what it is to be a lecturer and I was incredibly grateful for the opportunity to join in with discussions! I also ran a repeat of the session I led on Wednesday for students who were unable to make that time. I felt a lot more confident before this session than I had on Wednesday! But I was still a little anxious in case I missed something out or the students didn't get it. I know that I struggle with breaking my own knowledge of the programme down to the very basics to explain to people who have never even opened up the programme before, but I am confident that this skill will come in time, and I left the session feeling that each and every person had at least grasped the basic functions of how to begin constructing their own experiments.

Has technology changed the way we learn?

Nowadays, the appearance of some form technology is becoming more common in many facets of teaching (Luppicini, 2005). As individuals all over the world adapt to the introduction of ever-changing and developing technology, the world of education needs to move to incorporate these changes also to assist learning even further. The focus of this essay will be on the impact that interactive whiteboards (IWB’s) and virtual learning environments (VLE’s) such as Moodle can have on collaborative learning (Edwards, 2012), the introduction of Web 2.0 technologies into the learning environment (Frisch, Jackson and Murray, 2013; Luckin, 2010), how Twitter can be used as an instructional tool in higher education (Bozarth, 2010; Yakin and Tinmaz, 2013), and the ever increasing demand for the use of mobile technologies in distance education (Fuegen, 2012).

The meaning of the word ‘technology’ has changed immensely over the last decade (Edwards, 2012). It would be incorrect to think of technology as simply being the devices that are used to deliver teaching and learning material, such as computers. We need to instead include the processes and systems that are available within these devices. VLE’s have been developed to aid students in their learning by accessing course materials online. McRobb, Jefferies and Stahl (2007) propose that using VLE’s to control the learning experiences of students whilst still allowing for the facilitation of discussion through forums fits with both constructivist and positivist ways of thinking in relation to pedagogy. Rudd (2007) states that there are many factors that can influence the use of IWB’s as a “truly pedagogical tool” (p7), including the teachers understanding of how its use can assist collaborative learning and communication between students.

Introducing Web 2.0 technologies into the classroom can only allow for increased group collaboration and communication (Luckin, 2010). Frisch, Jackson and Murray (2013) have highlighted that, although it is obvious that students nowadays have considerable experience in using Web 2.0 technologies and incorporating them easily into their everyday lives, there is very little research available into the impact these have on learning. Greenhow, Robelia and Hughes (2009) state that, while the idea of incorporating Web 2.0 technologies into the classroom isn’t a new one, it is taking a long time for any empirical research to conclude its effectiveness on students understanding and learning.

Upon questioning, many students would explicitly claim that they are aware of the correct way of using the internet to search for valid resources to use in research papers. However, Frish, Jackson and Murray (2013) have determined that students, in fact, lack the ability to correctly identify what sources are considered to be valid and what are considered to be invalid in accordance to college standards. During this study, students were made aware of the correct procedure for searching for valid resources using Web 2.0 tools. These students reported that, overall, the Web 2.0 tools were incredibly helpful for separating relevant material from irrelevant material, and that this would ultimately be a beneficial skill for them throughout the rest of their academic careers.

Web 2.0 technologies can attempt to make online learning possible by increasing students’ participation in course material as a collaborative group of learners (Harrison and Thomas, 2009). Research has suggested that microblogging sites, such as Twitter, have the capacity for easy integration into learning environments for educational benefits (Chen, 2011). Microblogging sites allow its users to make posts of up to 140 characters. Bozarth (2010) insinuates that this restriction on space for text influences users to posts content that is brief and to the point. In relation to higher education, Twitter can be used to aid communication between students and also between a student and a lecturer about anything related to the course through the use of @ mentions, direct messages and retweets. Steenkamp and Rudman (2013) have implied that there are a number of current students that may be less text literate than previous generations due to an overreliance on technology. Using Twitter for educational posting may give these individuals a chance to become involved with discussions that they may not previously had the confidence for.

Yakin and Tinmaz (2013) set out to address how beneficial the use of Twitter would be in a higher education setting. Through a set of experiments across three time points and the ability to respond to open ended questions on the efficacy and usefulness of Twitter, Yakin and Tinmaz found that participants placed more emphasis on the beneficial power of using Twitter as a learning tool as time went on. Participants recognised that Twitter has the ability to be integrated in a formal university setting just as easily as it has been introduced into non-formal, social settings. Amongst answers given for what students liked about using Twitter as an educational resource were statements including “Twitter made instruction funnier” and “it increased communication in class”. However, on the flip side of this, some students reported that they considered tweeting and reading tweets during lessons to be distracting. From these results it can be suggested that Twitter does hold the power for easy integration into the world of education to aid further learning. However, further research needs to investigate the degree to which a non-formal site like Twitter can realistically be used in higher education.

Distance learning continues to grow as a way of providing flexible education to individuals who may find it difficult to attend physical learning environments (Fuegen, 2012). Ally and Samaka (2013) argue that every individual should be entitled to, at the very least, a basic level of education. The introduction of distance education over the years has allowed all different kinds of people the chance to become educated; this includes people who may not necessarily be able to attend a physical environment for learning as well as those who are able to attend college or university.

Mobile technologies have been heavily implicated in the substantial popularity of distance education courses due to the nature of being able to access course materials “anywhere at any time” (Chuang, 2009). According to Jones (2002), there are very few individuals in Western civilisations that do not at least have access to a mobile device. Increased mobility allows students to access course materials on the go, as well giving them the opportunity to get involved with discussion forums and communicate with tutors online at any time (Steenkamp and Rudman, 2013).

Although mobile technologies are unquestionably available and have been seen to be effective for teaching and learning in a new way, there can be a lot of pressure put upon tutors to provide relevant material that will allow their learners to be educated effectively. Realistically, there are many tutors who may struggle with evolve their pedagogical practices through the use of mobile technologies due to other constraints put upon them; many educators do not have sufficient training in creating materials that will be supported by mobile technologies, and some simply don’t feel they have the time to learn how to support mobile technologies in education (Shim and Shim, 2001). Nonetheless, mobile technologies will be ever present within the field of education and, in particular, distance learning.

Technology has evidently changed the way that educational material can be learnt. The introduction of Web 2.0 tools will continue to aid the shift to a collaborative way of learning, as will the implementation of using IWB’s in classrooms. Mobile technologies will continue to develop and grow, as will the possibility for further learning anywhere at any time. Steenkamp and Rudman (2013) conclude that students who are currently entering higher education have grown up in a media rich society, therefore have adapted to using many different forms of technology with ease in their everyday lives, including in their learning. However, Lawrence and Lentle-Keenan (2013) warn that technologies should only be utilised in situations that will actually allow students to develop the necessary transferable skills they require to use in their everyday lives and their everyday education. They also suggest that simply injecting technology into teaching can cause two problems; firstly, students may become over reliant on the information that they expect to be available to them online and secondly there may be potential for students to bypass an independent learning style. There are still students and teachers alike who will prefer the method of face-to-face interactions with each other, therefore using the newest technology for learning should be methods of appropriateness rather than convenience.

TEDtalk

I have chosen this TEDtalk on the psychology of evil by Phillip Zimbardo because I am already fascinated by the work of Zimbardo himself. Zimbardo is most famously known as the leader of the notorious 1971 Stanford Prison Experiment in which 24 clinically sane male volunteers were put into roles of ‘guards’ and ‘prisoners’ in a mock prison in the basement of Stanford University. The study that had been scheduled to run for two weeks had to be abandoned after just six days due to participants experiencing severe distress and trauma. Guards became incredibly sadistic and prisoners experienced severe deindividuation, and became passive and nervous.

In this talk, Zimbardo makes reference to his Stanford Prison Experiment and how he has since attempted to answer the question “what makes people go wrong?” He not only acknowledges his fascination with the way in which the behaviour of the guards and prisoners changed in this study, but also how personally consumed he became with the study itself. Ordinary people can be transformed in an alarmingly short space of time when the situational context is changed.

In his 2007 book ‘The Lucifer Effect’, Zimbardo focuses on all the negatives that people have the potential to become. He states that the line between good and evil is not, as many would think, fixed and impermeable, but that it is in fact permeable and moveable. The psychological definition of evil includes the conjecture that evil is born from the exercise of power, and this can clearly be witnessed in the behaviours of the guards in the Stanford Prison Experiment.

When photographs emerged of the horrific incidents at Abu Ghraib in 2004 Zimbardo felt as disturbed as anyone would have, but also felt a jolt of disturbing familiarity. Three decades before he had witnessed first-hand the way in which an individuals’ behaviour can be negatively altered with the introduction of power. In this talk, he states that “the landmark Stanford Prison study provides a cautionary tale for all military detention operations” and that giving any person power without oversight is simply providing a prescription for abuse.

The pictures of Abu Ghraib shown in this video are a clear visual illustration of evil. American soldiers are photographed torturing and humiliating prisoners in order to break the will of the enemy. Zimbardo, however, hypothesises that American soldiers are good people, and it is merely the power inflicted upon them that makes them bad.
 

“I knew that in the Stanford experiment, I began with good apples and that it was the place that corrupted them, so my hypothesis was that maybe these soldiers were good apples and it was the barrel at Abu Ghraib that corrupted them.”
 

Zimbardo appeared as an expert witness for a defendant in the Abu Ghraib trial; an individual who was put in charge of the night shifts at the interrogation hold at the prison and who was featured in a number of the horrifying pictures. Zimbardo argues that the question of WHO is responsible is not applicable to the case – the question needs to be altered to WHAT has caused this change in behaviour; in terms of dispositional (internal), situational (external), and systemic (political/legal) powers.

Zimbardo ends his talk with an introduction to how education needs to highlight heroism, and allow individuals to develop a heroic imagination. He discusses how we all have the ability to do heroic deeds, just as we are all capable of doing evil. Heroism, he implies, is the antidote to evil. In his most current research, Zimbardo intends to tackle the following research question:

 “What pushes some people to become perpetrators of evil, while others act heroically on behalf of those in need?"

Phillip Zimbardo’s words throughout this TEDtalk are incredibly thought provoking. His powerful speech is reinforced through the use of visual illustrations of the horrors of Abu Ghraib, and his open honesty about his most famous study; the Stanford Prison Experiment. The picture below seems to summarise the whole talk. Zimbardo makes reference to this picture during his presentation and it was created by a New York Cartooner called Mick Stevens. The picture depicts the conflict between good and evil in each and every one of us.

ARRRRGGGHHHH!!!

This lovely lady is a perfect representation of my mood over the last hour!
Whilst I still think that Blogger is a great way of reflecting, it is getting so hard to keep up with HOW to blog when you're constantly switching computers! Or mobile devices for that matter!

So Blogger only allows the user to 'compose' a post when using Mozilla Firefox in University.. but only when the user is in a computer suite. This does not include the library where the computers don't have Firefox installed on any of the computers! Internet Explorer appears to reject all 'composing'.

The confusion doesn't end there! My laptop is equipped with Windows 8. I downloaded Firefox specifically to enable myself to blog efficiently. However, when attempting to blog on Firefox on this laptop, it does not work! Composing is not the problem.. saving and publishing the posts are! So I revert to Internet Explorer (which I previously assumed wouldn't work) which ends up working PERFECTLY! Or does it? Of course not! When trying to insert an image that is saved to the picture library, Internet Explorer decides to completely reject this now instead! Enter Firefox yet again just to insert pictures.

Before I ended up with a laptop in pieces I decided to try and use the Blogger app on my iPhone instead to FINALLY post the post that I had been working on for the previous hour! I open up a saved draft, the writing content done on Internet Explorer, the picture uploaded through Firefox and the actual post eventually published through the use of my iPhone.

Talk about utilising available technology!!!

Micro Teach One

On Thursday 3rd October I delivered my first micro teach to my peer group for the purpose of my assignment. I chose to present on the topic of ethical considerations in psychological research as this is a topic that would be taught to my usual learner group; psychology students, at any level.

 

I found the experience... different. At first I was extremely nervous! This was picked up by Caroline and the rest of the group as I was speaking extremely fast! However, as the session progressed, I started to feel more comfortable and in control of my nerves.

It was evident that everyone was slightly nervous as they began their presentations. I think the micro teaching sessions are a good way of easing the student teacher in to the teaching environment by presenting to a small group. I know that I certainly appreciate the opportunity to build up my confidence in presenting to a group!

The immediate feedback given by Caroline was very helpful and allowed me to instantly reflect upon what I felt went well, what I felt was wrong with my presentation, and what I would aim to do next time to rectify the issues I faced. I did find, however, that when it came to writing the assignment part of this assessment I struggled to articulate in words how the session went! I certainly need some practice on reflective writing. Next time I intend to make sure I write down the feedback that is given to me as a guide for writing my reflections!
