Given the need to educate future critical thinkers, it is necessary to explore preschool teachers' level of argumentation about socioscientific issues in order to facilitate their use of appropriate strategies for effective argumentation in their own classrooms. To achieve this aim, it is also necessary to propose the use of a set of previously…

This experimental study explores how source use features impact raters' judgment of argumentation in a second language (L2) integrated writing test. One hundred four experienced and novice raters were recruited to complete a rating task that simulated the scoring assignment of a local English Placement Test (EPT). Sixty written responses were…

Recent trends have shifted the focus of science, technology, engineering, and mathematics (STEM) education onto practice-based learning, to encourage opportunities for students to engage in science and engineering practices (SEPs) with the goal of more meaningful participation and engagement in authentic STEM experiences for all students. However,…

Justifications play a central role in argumentation, which is a core topic in school science education. This paper contributes to this field of research by presenting two studies in which we assess students' justifications for supporting or rejecting hypotheses in the physics lab based on self-collected, anomalous experimental data, which are…

When asked to determine whether a syllogistic argument is deductively valid, people are influenced by their prior beliefs about the believability of the conclusion. Recently, two competing explanations for this belief bias effect have been proposed, each based on signal detection theory (SDT). Under a response bias explanation, people set more…

Student portfolios are increasingly used for assessing student competences in higher education, but results about the construct validity of portfolio assessment are mixed. A prerequisite for construct validity is that the portfolio assessment is based on relevant portfolio content. Assessment criteria, are often used to enhance this condition.…

Debate paradigms, which at one time established standards to help judges evaluate arguments and rules to guide debaters' argument choice and strategy selection, no longer offer consistent guidance for either judges or debaters. An increased emphasis on creativity and flexibility has led to a general unwillingness to use a rigid debate format. The…

Evaluators of argument are frequently confronted by conflicting claims. While these claims are usually based on probabilities, they are often resolved with the accepted claim treated as though it were "true," while the rejected claim is treated as though it were "false." Scenario testing is the label applied to a set of…
