What major discrepancy did the researchers identify in the students' overall evaluation versus their justification performance?

While students were generally accurate at differentiating highly credible texts from less credible ones, their ability to explain and justify their ratings was not sophisticated.

How was students' prior topic knowledge score calculated on the final test?

It was measured using true-false items, resulting in a maximum possible score of eight points after removing items without variance.

What criteria did a student's justification need to meet to be scored at the highest level (Level 3)?

The justification had to be elaborated and relevant, containing at least two relevant reasons, a warranted explanation, or a rebuttal.

What defined a 'Level 1' justification in the researchers' qualitative coding rubric?

Level 1 justifications were tangential or vague, typically supporting the correct evaluation direction but using an incorrect credibility aspect.

What constituted a 'Level 0' justification according to the study's qualitative scoring system?

An inadequate justification that was unclear, irrelevant, repeated the prompt's basic information, or demonstrated a clear misunderstanding.

Why did students find it difficult to justify their evaluations of the journalist's expertise?

Some students incorrectly evaluated the interviewed doctor instead of the journalist, or assumed that journalists have no personal knowledge of their topic.

Why did students perform best when justifying the benevolence of the candy company CEO?

The CEO's commercial motivations and conflict of interest were highly explicit and easy to recognize on the webpage.

What limitation did the distance-learning context during the pandemic introduce into the study's administration?

Students completed the tasks at home without face-to-face supervision, which could have negatively impacted their motivation.

How did the length of the assessment task pose a potential limitation to the results?

The task demanded 16 open-ended justification items, which could have led to participant fatigue and poorer quality answers near the end.
