This study investigated the impact of participating in a year-long digital-fabrication course on high-school seniors' problem-solving skills, with a focus on problems involving mechanistic systems. The research questions centered on whether working in a makerspace impacted students' abilities to solve such problems and whether the process data…

This study was carried out to develop a test to assess algorithmic thinking skills. To this end, the twelve steps suggested by Downing (2006) were adopted. Throughout the test development, 24 middle school sixth-grade students and eight experts in different areas took part as needed in the tasks on the project. The test was given to 252 students…

Sourcing is the ability to evaluate information by analysing source parameters such as author's expertise on a given topic. Past research, mostly based on school-related materials and tasks, shows that adolescents do not pay attention to source parameters when evaluating online scientific information. However, recent research has suggested that…

Motivated by a curriculum privileging number-based strategies but national tests highlighting students' reliance on standard algorithms, this study analyses 2,216 Danish Grade 3, 6 and 8 students' solutions to various multidigit arithmetic tasks, each designed to elicit shortcut strategies, against background variables including sex, ethnicity and…

With problem-solving as the focus and wisdom as the goal, the concept of giftedness is reconceptualized in the 21st century context. The two most prominent constructs in the field of education for the gifted, creativity and intelligence, are integrated into a view of exceptional talent as consisting of the ability and willingness to solve complex…

Background: Adaptive expertise is a highly valued outcome of mathematics curricula. One aspect of adaptive expertise with rational numbers is adaptive rational number knowledge, which refers to the ability to integrate knowledge of numerical characteristics and relations in solving novel tasks. Even among students with strong conceptual and…

The work of Niklaus Wirth, designer of the Pascal programming language, has led to the introduction of programming in schools in many countries often leading to a transformation in the way of thinking. In this article, we provide a retrospective analysis of the Lithuanian experience driven by Pascal and discuss the main ideas about teaching…

The instructional effect of worked examples has been investigated in many research studies. However, most of them evaluated the overall performance of the participants in solving post-intervention problems, rather than individual step performance in multi-step problems. The two experiments reported in this article investigated the relations…

Advancement of testing of mathematical problem-solving skills calls for open-ended, realistic tasks particularly susceptible to bias, compromising the score validity and fairness of tests. Informed by universal design principles, this study framed 360 prototype items developed for the "Problem-solving Measures Grades 6-8 Computer Adaptive…

In this paper we present a qualitative analysis based on data collected by means of an eye-tracker tool, concerning the outcome of a mathematical analysis question administered to a group of candidates of university level or higher. One of the research aims is to highlight similarities and differences in the visual observation of the question…

The aim of this study was to characterise thoroughly the differences between Physics Olympiad competitors' and regular students' successes and approaches in relation to counterintuitive dynamics problems (CDPs) in order to discover some of the differences between skilled problem-solvers and those with fewer such skills. A total of 23 Physics…

This article describes how a class of year 9 (age 13-14) students engaged in a research-informed and negotiated action science project to address socio-scientific issues. The project was informed by the 'STEPWISE' curriculum framework. Evidence suggests that students benefited from collaborative problem-solving, developing confidence, motivation…

Development of students' mathematical skills is associated with quality teaching, which means that mathematics teachers should be able to successfully solve mathematical, teaching, and professional problems. The article aims to describe the assessment system of mathematics school teachers' professional competence, which helps identify gaps in…

The present study aims to explore global expertise of including 21st century skills in teacher preparation programs and the reality of including (information and communication, thinking and problem solving, as well as interpersonal and self-directional) skills in these programs. It also highlights the differences in the reality of including 21st…

Education researchers have sought to address the divide between research and persistent problems of practice faced by educators through technology, pedagogy, and methodology innovations (Anderson & Shattuck, 2012; Mishra & Koehler, 2007; Richey, 1998). Barriers to the successful development and implementation of technological innovations…
