For an exam to be reliable it needs to measure candidates’ performance accurately and consistently according to the objectives of the exam. Exam reliability statistics such as Cronbach’s Alpha, which Maxexam uses, help examiners to understand how reliably the exam is measuring different candidates’ ability.
At the core of Ebel lies a matrix developed by the examining body. The problem with Ebel arises from the fact that the structure/type of question is often not taken into account when determining the matrix itself, or where a particular question sits within the matrix.
The Maxexam Active Invigilation Module (AIM) has been introduced to help healthcare educators to ensure exam integrity for remote exams.
We need doctors and dentists more than ever during these difficult times, and students still need to be able to complete their education and graduate in a way that ensures that they are safe to practise. We look at whether running exams on a distributed basis with remote invigilation is the answer.
Prompt, personalised exam feedback motivates students as well as giving them vital information to improve their learning and revision going forward. This is particularly important when exams are sat on a distributed basis.
We are delighted to announce that we have won an Epic Games MegaGrant to explore the use of Virtual Reality (VR) within our Maxexam software. Epic Games launched these awards to reward companies ‘doing amazing things’ utilising Unreal Engine – a suite of development tools for people/companies using real-time technology. Maxinity is a key award winner and we will be using the funds received to investigate the use of VR in a clinical exam setting.
We take a balanced view looking at both the pros and cons of this method of assessment.
The Horst Partial Knowledge Index or PKI (Maxinity terminology) is a statistic which can be used to help understand and consequently improve item reliability. It is particularly useful at identifying problem items, as a negative Horst PKI indicates that more candidates answered a question with a specific wrong answer (most popular distractor) than the correct answer.
The PCC measures the strength of the relationship between two variables - in an exam this would be between candidates’ item/question/scenario marks and their exam marks. The Pearson's Correlation attempts to draw a line of best fit through the data points plotted on a graph, and the coefficient evaluates how far away from the line of best fit these data points are.
