TOPIC: Item Analysis based on Classical Test Theory

The concepts of item analysis based on classical test theory were discussed. Included in the video is the step-by-step guide on how to use the CITAS software in conducting item analysis in accordance with the classical test theory criteria. Interpretation of the results generated by the software were discussed. CITAS is short for Classical Item and Test Analysis Spreadsheet. It is a free excel software developed by the assessment corporation in the United States of America.

December 6, 2020 || Part One

TOPIC: Item Analysis based on Rasch Analysis

In this webinar, the concepts and practical applications of item analysis based on Rasch Model were discussed. Part1 is about the discussion of the concepts of item analysis based on Rasch model while Part2 contains discussions on how to use the Winsteps/Ministeps software in conducting a Rasch analysis for dichotomous data (e.g., multiple choice test). Hence, Part 2 deals about the following topics: How to prepare the test-takers data in MS Excel; How to convert the Excel datafile into Winsteps datafile; How to perform the Rasch analysis; How to view the Rasch analysis results; How to identify fit and misfit items; How to exclude misfit items in the Rasch analysis; How to preparing the basic results of Rasch analysis using the MSWord template; and How to conducting differential item functioning (DIF). The interpretation of the results are provided.

TOPIC: Part Two of the Item Analysis based on Rasch Analysis (Video for the Applications using Winsteps/Ministeps)

Part2 contains discussions on how to use the Winsteps/Ministeps software in conducting a Rasch analysis for dichotomous data (e.g., multiple choice test). Hence, Part 2 deals about the following topics: How to prepare the test-takers data in MS Excel; How to convert the Excel datafile into Winsteps datafile; How to perform the Rasch analysis; How to view the Rasch analysis results; How to identify fit and misfit items; How to exclude misfit items in the Rasch analysis; How to preparing the basic results of Rasch analysis using the MSWord template; and How to conducting differential item functioning (DIF).

TOPIC: Item Analysis based on Item Response Theory

The concepts of item analysis based on the three IRT Models such as One-parameter, Two-parameter, and Three-parameter models) were discussed. The three parameters are: item difficulty, item discrimination, and guessing. All of these are covered in the Part 1. Part 2 covers the discussion on how to use the Xcalibre software in conducting IRT analysis for dichotomous data (for example, multiple choice test). Interpretation of the results generated by the software are provided.
