Examination for the Certificate of Proficiency in English

Description

This is data from the grammar section of the Examination for the Certificate of Proficiency in English (ECPE), administered annually by the English Language Institute at the University of Michigan. This data contains responses to 28 questions from 2,922 respondents, which ask respondents to complete a sentence with the correct word. This data set has been used by Templin & Hoffman (2013) and Templin & Bradshaw (2014) for demonstrating the log-linear cognitive diagnosis model (LCDM) and the hierarchical diagnostic classification model (HDCM), respectively.

Usage

ecpe_data

ecpe_qmatrix

Format

ecpe_data is a tibble containing ECPE response data with 2,922 rows and 29 variables.

• resp_id: Respondent identifier

• E1-E28: Dichotomous item responses to the 28 ECPE items

ecpe_qmatrix is a tibble that identifies which skills are measured by each ECPE item. This section of the ECPE contains 28 items measuring 3 skills. The ecpe_qmatrix correspondingly is made up of 28 rows and 4 variables.

• item_id: Item identifier, corresponds to E1-E28 in ecpe_data

• morphosyntactic, cohesive, and lexical: Dichotomous indicator for whether or not the skill is measured by each item. A value of 1 indicates the skill is measured by the item and a value of 0 indicates the skill is not measured by the item.

Details

The skills correspond to knowledge of:

1. Morphosyntactic rules

2. Cohesive rules

3. Lexical rules

For more details, see Buck & Tatsuoka (1998) and Henson & Templin (2007).
