{"abstract":"The Philippines scored 297 in Mathematics and 249 in Science in the 2019 Trends in International Mathematics and Science Study (TIMSS), the lowest among 58 participating countries. The study's findings open the door to determining various factors that can help alleviate the students' alarming performance. As a result, this study is a quantitative study that aimed to determine student performance in TIMSS Mathematics released items and predictors using the selected profile variables. The study included 49 high school students in total. Regression analysis was used to determine whether there are any significant variables that influence the assessment's outcome. The study's main tool was the 2011 TIMSS Mathematics released items. The findings revealed that significant predictors include grade 7 math average, home computer availability, and gender. The study can be used as a guide to determine students' strengths and weaknesses in TIMSS released items.","abstract_source":"original","authors":["Janwin Magas"],"date":"2023-01-27","doi":"10.5281/zenodo.7575160","id":981,"issue":11,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"f4e818a506b6ceef1ee9a96e3ebb0083b5f5368d85fb7b539eb045dbab87497a","schema":"scimatic-article/1","title":"Predictors of Student’s Performance in TIMSS Mathematics Released Items","volume":6}

1. The record, from the token's own metadata:

printf '%s' "$(curl -s https://scimatic.org/nft/articles/981.json | jq -r .canonical_record)" | sha256sum

2. The hash stored on chain (contentHash(981)):

curl -s https://rpc.scimatic.net -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_call","params":[{"to":"0x0E596B4bb924937aA35D9b342A90347ed6F05eF8","data":"0xf3e0c29000000000000000000000000000000000000000000000000000000000000003d5"},"latest"]}'

The two must be equal (the second with a 0x in front).
