The Purpose of Classroom Observation

Classroom observations have many different names depending on the country and, sometimes, the institution involved. Teacher observations, lesson walkthroughs or learning walks are just a few of the alternative names we’ve heard. But no matter what name they go by, the primary purpose of a classroom observation will always be to ensure that the student is learning effectively.

This is done by observing the teacher to ensure that they are providing the best possible learning environment and lessons that are appropriate to the level of the student. It should also check that teaching is centred around each and every pupil and that nobody is being left behind in the class.

Observation can, and should, provide insights into the strengths and weaknesses of a teacher’s practice and help identify training needs to bring out the full potential of both teacher and student.

There are a few different types of observation. They may be done once or twice per year by the headteacher of the school or by an education inspector as part of a teacher’s formal assessment or they may be more informal, usually peer-to-peer, and used as a self-improvement tool. More rarely, they may be done as part of a study into education and educational trends.

How to Conduct a Classroom Observation

There are many ways to conduct a classroom observation, some standardised, some bespoke. The following is a list of 6 common standardised checklists:

• Classroom Assessment Scoring System (CLASS)

• Framework for Teaching (FfT)

• International Comparative Analysis of Learning and Teaching (ICALT)

• International System for Teacher Observation and Feedback (ISTOF)

• Mathematical Quality of Instruction (MQI)

• Generic Dimensions of Teacher Quality

If we look at the CLASS system, as an example, it splits the observation into three distinct sections or domains, namely Emotional Support, Instructional Support and Classroom Organisation. Each of these domains are split into subdomains which measure the learning climate, behaviour, modelling and other aspects of teaching.

The advantage of this is that the observer has a ready made checklist for conducting a lesson observation. This is also standardised meaning that data taken from observations can be easily compiled and compared with other teachers, departments and schools.

Of course, an institution may opt to create their own bespoke checklist based on their own teaching standards which has the added benefit of creating something which takes into account varying teaching styles.

In any case, once the method of conducting an observation has been decided, the teacher should be informed in advance and a time agreed for the observation. Although this is regarded as good practice, there are those who say that an observation should be conducted without forewarning. This means that the teacher is seen in their natural state without much time to prepare.

The observer should sit at the back of the class and be as unobtrusive a presence as possible and avoid becoming a part of the class.

Feedback from the observation should be given in a timely manner and no more than 24 hours after the fact. This allows for fresh recollection on the behalf of both teacher and observer.

The Disadvantages of Classroom Observation

Although classroom observations are designed to help improve both the teacher and the student, there are some severe disadvantages in how they are performed meaning that the overall picture of the teacher being observed may be askew.

Let’s take a look at some of these disadvantages…


As we mentioned in the opening paragraph, classroom observations can be very stressful to those involved. The teacher probably hates the idea of being observed in an environment which they regard as being their own. Usually, they are in charge of what happens in the classroom and they are the authority. Now, that authority is not only being undermined, it’s being scrutinised.

And what’s worse? This observation session will be put on their permanent records, possibly limiting their future promotion prospects.

This can cause added stress to an already stressful job and, as a result, the teacher may not perform to their usual high standards meaning that the results of the observation are incorrect.

The observer may also feel the stress. They are being asked to assess the performance of their peers and colleagues, something which may not feel entirely natural to them. This is on top of the extra paper-work and bureaucracy involved.


Classroom observation can be disruptive, there’s no denying this. When a headteacher sits in on a class it can change the atmosphere of a class. Students may feel reticent, reluctant to be as open in the face of authority.

Worse, it may make some students act out, displaying negative behaviour that they wouldn’t normally dream off in a normal class. Both of these changes in behaviour can impact negatively on a teacher’s performance and add even more to the stress of the situation of all involved.

Bias and Objectivity

It doesn’t matter where in the world you are or in which field you work, you’ll encounter a certain amount of bias and subjectivity...and teaching is no different.

In teaching, this especially comes into play when an older, more set-in-their-way teacher is observing a young gun, straight out of university and desperate to put some of their new teaching ideas into practice.

If the older teacher doesn’t agree with the teaching methods, no matter how effective, this will reflect negatively on their assessment.

Apart from this, people often hold grudges or are affected by office politics. This is especially damning when conducting formal assessments.

A Rare Off Day

Apart from this, teachers, like everyone, have off days. Maybe they’re feeling ill or had an argument with their partner or have simply had a restless night. All of these things can affect performance and, if these off days happen to fall on the day of an observation, it can seriously affect the results.

On average, teachers teach for six hours per day, 180+ days a year. They can’t be expected to be at the top of their game every single minute in such a stressful role.

Alternative Ways of Conducting Classroom Observations

Ok, so far we’ve asserted that classroom observations are necessary but that there are many downsides to them too. But what if there was a way of conducting observations which added minimal stress to the teacher, was 100% objective, meaning that bias didn’t play a role, and could be done in a way which was completely unobtrusive, avoiding class disruption?

Well, there analysis with Codimg!

What Exactly Is Codimg?

Codimg is a video analysis solution which allows you to film any classroom situation, analyse it and present your conclusions.

To start your analysis, you create a button template which is completely adaptable to the situation you want to analyse. For example, check the example below which is a template we have created based on the CLASS system of observation that we mentioned above.

The Importance of Classroom Observation (5)

We would be happy to share this checklist template with you. Simply click the link above and request it. If you're not yet a Codimg user, we'll even set you up with a free trial of the software. We can't say fairer than that!

You watch a lesson and click the buttons when you see something that is relevant to the teacher’s evaluation. This can either be done live with a laptop or iPad, or it can be done retrospectively from filmed footage. Clicking the buttons creates a short video clip of that exact moment and adds the information to an interactive database.

At the end of the session, this information can be analysed and the video clips used to create a quick video presentation which can be exported and sent to the teacher so they can see the results of the observation for themselves.

This is just a quick overview of the basic functions of Codimg. In addition, it contains a wealth of tools for analysis, data visualisation and presentation. In short, it makes classroom observations much quicker and easier. It accentuates the positives and negates all the negative points we mentioned above.

How? Let’s take a closer look.

Codimg Is 100% Objective

Filming a lesson, analysing it and presenting the video to the teacher completely destroys any bias that there might be in the process. It provides irrefutable evidence of what has happened in the classroom, meaning that observers will be more confident in their assertions and teachers will get more out of the session.

Codimg provides real, tangible, actionable evidence of where improvement is needed. And it doesn’t have to be negative! It can be used as a motivational tool, showing off the good points of a teacher’s practice too!

Codimg Is Discrete

There’s no need for the observer to be present in the classroom. A video camera can be set up at the back of the classroom and, at the start of the lesson, the teacher hits the record button. The observer can then collect the footage and complete the observation at their leisure.

The Importance of Classroom Observation (7)

This takes the stress and disruption out of the whole process. The students don’t act up in the face of an authority figure in the classroom and both the teacher and observer are more relaxed. This makes it much more likely that a true picture of what happens during the lesson is captured.

Codimg Is Adaptable

Codimg is not only useful for classroom observations. Any educational process can benefit from video analysis.

Take Colegio Miralmonte in Spain, for example. They use Codimg as a student evaluation tool. Again, this process is easy, non-disruptive and easily adaptable to any situation. At Miralmonte it’s particularly useful for subjects which have spoken or presentation elements such as music, drama, language learning or their extracurricular debating club. Video footage is often passed on to students and they can self-evaluate their performances, identifying mistakes and self correcting. Codimg is a great learning to learn tool in this regard.

Torquay Academy in the south of England also uses Codimg, although more in line with what we’ve spoken about in this article, i.e. as a tool for teacher coaching. Check out this article for a real case study on how Codimg is used practically at a real school.


Classroom observation is an essential part of teaching. It checks and adjusts a teachers performance meaning that students get the most out of their lessons, improving their academic performance and, thus improving the overall performance of the school.

But that doesn’t mean the process can’t be improved upon. Traditional methods of observation can be stressful and disruptive, something that video analysis with Codimg can negate in a manner which is 100% objective.

We’d love the opportunity to show you how Codimg can be used at your school. Contact us today for more information and we’ll set you up with a free trial and look at how a video analysis solution can be tailored to your particular needs.
