This research aims to describe students' level of algebraic reasoning based on the adversity quotient types of climber, camper, and quitter in solving PISA model mathematics problems. This research is descriptive research with a qualitative approach. The research began by administering a questionnaire to determine the student's adversity quotient…

Self-concept is an important noncognitive predictor of learning success and academic achievement, but mechanisms behind these effects are mostly unknown (Marsh, 2006). We analyzed the influence of mathematical self-concept on university students' eye movements in reading mathematical PISA items in a mathematical and a problem-solving context. In a…

With rising importance of collaborative problem-solving skills (CLPS) for the new information age, the PISA 2015 assessed students' CLPS skills on a large scale. This new attempt to measure CLPS raises an issue of validity. The purpose of this research is to examine evidence for convergent validity of CLPS through investigating the relationships…

Typically, more primary students qualify for mathematics intervention support than schools have the capacity to assist. This highlights the importance of every primary mathematics teacher having the expertise to design inclusive and responsive curricula and instruction for students who may experience difficulty. Our study addresses this issue…

Problem-solving is one of the 21st-century skills. However, students still have difficulty solving sequences and series word problems. The purpose of this research is to analyze students' errors in solving sequences and series word problems based on problem-solving steps of Polya. The research method is descriptive qualitative. The research…

This conceptual paper proposes a model to describe the quality of student dialogue during participative collaborative problem solving. Drawing on the participation metaphor of learning, we argue that the construct of mathematical sophistication is useful to describe the quality. We then present two frameworks, mathematical competencies and…

In educational assessments two types of missing responses can be discerned: items can be "not reached" or "skipped". Both types of omissions may be related to the test taker's proficiency, resulting in non-ignorable missingness. This paper proposes to model not reached and skipped items as part of the response process, using…

Nowadays, there is a consensus that inquiry-based learning contributes to developing students' scientific literacy in schools. Inquiry-based teaching strategies are promoted for the development (among others) of the cognitive processes that cultivate problem solving (PS) competence. The build up of PS competence is a central objective for most…

This paper briefly discusses four measurement challenges of data science or "big data" in educational assessments that are enabled by technology: 1. Dealing with change over time via time-based data. 2. How a digital performance space's relationships interact with learner actions, communications and products. 3. How layers of…

This paper reports how the context in which a mathematics item is embedded impacts on students' performance. The performance of Year 10 students on four PISA items was compared with performance on variants with more familiar contexts. Performance was not better when they solved items with more familiar contexts but there was some evidence that…
