Workshop 2: Test Item Analysis

Test Item Analysis for English Teachers:
Applying Classical Test Theory using Excel

Workshop Facilitators:

Chihiro Inoue, CRELLA, University of Bedfordshire, chihiro.inoue(a)
Sathena Chan,CRELLA, University of Bedfordshire, sathena.chan(a)
Carolyn Westbrook,Southampton Solent University, carolyn.westbrook(a)

Summary of workshop:

This workshop aims to provide foreign language teachers with hands-on sessions on conducting basic item analysis using classical test theory (CTT). Using sample data sets in Excel spreadsheets, various functions will be introduced to calculate descriptive statistics (e.g., frequency tables, histograms, central tendency and dispersion) and reliability, as well as to conduct item analysis (e.g., facility values and discrimination, i.e. point biserial, distractor analysis).

Along with the hands-on session, lecture sessions are also given (using sample items from different item types) to raise awareness in test design, item writing, scoring methods and inputting data into spreadsheets. The intended learning outcomes are:
- An understanding of key concepts in language testing
- An understanding of the thinking behind item analysis in CTT
- An understanding of the functions for item analysis in Excel.

By using Excel, this workshop can provide English teachers with more accessible means for conducting their own item analysis in CTT. Teachers will also benefit from being able to take home the Excel templates for their own future use.

Prior knowledge required:

- Basic knowledge about Excel (i.e. what it looks like and how text / numerical data can be entered)
- Some experience of writing tests and reporting scores at their school
All information (handouts and datasets) will be provided during the workshop. However, if participants have data sets from tests they have run, they can use those to practise the activities we will be doing or for additional practice between sessions.

Please bring your laptop, with Microsoft excel installed (part of the Office package).
