Graduate Students in Research on International Large Scale
Assessments – 魅影直播; PIRLS Lab

The work of the 魅影直播; PIRLS International Study Center staff is supported by graduate assistants who are students in the Measurement, Evaluation, Statistics, and Assessment (MESA) program at Boston College鈥檚 Lynch School of Education and Human Development. The current graduate researchers assist with operational aspects such as assessment development and assembly and work on research projects aimed at the 魅影直播 and PIRLS projects.

Jenny (Ji Yoon) Jung

Graduate Research Assistant, 魅影直播

Ji Yoon is a Doctoral candidate in Measurement, Evaluation, Statistics, and Assessment. Her dissertation concerns automated scoring of written response items in international large-scale assessments.

At 魅影直播; PIRLS, Ji Yoon has performed Item Response Theory (IRT) analysis for the LaNA and Rosetta Stone Projects, which measure the literacy and numeracy proficiencies of students in low- to middle-income countries. She has also run automated scoring for written response items using 魅影直播 2023 field test data and e魅影直播 2019 data as part of the 魅影直播 2023 Automated Scoring Project.

Dihao Leng

Graduate Research Assistant, 魅影直播

Dihao is pursuing a PhD in Measurement, Evaluation, Statistics, and Assessment. Her dissertation, supervised by 魅影直播; PIRLS executive director Dr. Matthias von Davier, aims to advance the application of process data in the realm of large-scale assessments. She has also worked on the automated scoring of mathematics expressions and on utilizing LLMs for the automated generation of mathematics items.

Outside of work, Dihao has applied hierarchical linear models to investigate the individual- and school-level effects of private tutoring on mathematics achievement in South Korea, and has employed mixture models to explore students' attitudes towards mathematics.

Meng Lyu

Graduate Research Assistant, 魅影直播

Meng is a PhD student in the Measurement, Evaluation, Statistics, and Assessment program with a focus in psychometrics.

At 魅影直播; PIRLS, Meng works on systematically cataloging and structuring the prompts utilized across various AI-driven initiatives. She also explores the use of multi-model LLMs and machine learning models to generate fourth-grade mathematics items for the 魅影直播 assessment.

Jeneve Swaby

Graduate Research Assistant, PIRLS

Jeneve is a second-year PhD student in Measurement, Evaluation, Statistics, and Assessment. She works on the development of reading assessment instruments for PIRLS: reviewing feedback from experts and countries, creating text maps for reading passages, and ensuring the passages are sensitive to cultural differences and suitable for fourth-grade students. Jeneve also contributes to an exploratory project for generating items using artificial intelligence, reviewing the output according to the four reading comprehension processes specified by the PIRLS framework.

After obtaining her PhD, Jeneve hopes to work as a psychometrician/ quantitative methodologist on large-scale assessments that influence policy decisions. She is interested in using process data to identify sources of variation in test-taker performance and to support the valid interpretation of test scores.
