To understand the ways that manipulatives might support changes in students' reasoning about algebraic generalizations, a constructivist teaching experiment was conducted with two sixth-grade students. The students interpreted numerical situations with units of one and could construct units of units in mental activity. Initially, the students'…

We report a study examining, for the first time, the effectiveness of engagement in dialogic argumentation in relation to its ability to promote integration of multiple source perspectives in an argumentive writing task after reading controversial multiple texts. Sixty-four primary school students engaged in a dialog-based intervention aiming to…

The search for alternative indicators of school quality has ignored a powerful data point that most schools already collect--a student's grade point average. Might it also be used to evaluate schools? To find out, we asked the University of Maryland's Jing Liu and co-authors Seth Gershenson (American University) and Max Anthenelli (UMD) to conduct…

In this paper we present a novel adaptation of a tri-phase assessment tool, originally devised to investigate students' linear equations-related strategy flexibility, to evaluate Danish grade-six students' multidigit arithmetic-related strategy adaptivity and flexibility. Participants, 731 students, median age 12 years and drawn from 20…

Interest in teachers' moves to classroom discourse has started to increase since how teachers respond to students' thinking influences students' learning. The purpose of this study was to investigate the moves used by one sixth grade mathematics teacher at a public middle school in Turkey to support student reasoning in mathematics instruction and…

Background: Research has shown that mathematics anxiety negatively correlates with primary school mathematics performance, including fraction knowledge. However, recently no significant correlation was found between fraction arithmetic performance and state anxiety measured after the fraction task. One possible explanation is the natural number…

The general aim of the study was to improve students' awareness of gender equality. An instructional design was developed in which mathematics, science, information technologies and software (ITS) courses were integrated, with the theme of gender equality at the center. The method of the study was determined as a case study. The participants of…

The ability to recognize and construct nets is a fundamental aspect of spatial reasoning skills; however, there is a lack of understanding regarding effective instructional sequences for fostering this ability. The aim of this study is to test a Hypothetical Learning Trajectory for enhancing sixth-grade students' understanding of rectangular prism…

Colour in the classroom, either in isolation or in conjunction with other environmental factors, is an element that has been widely discussed in the scientific literature, albeit not systematically. On the other hand, its evolution towards coloured light, made possible in recent years by light emitting diode (LED) technology, has hardly found a…

Integrated writing assessments are tasks that require students to construct an essay using evidence from source texts. Topic models are statistical models used to analyze text. This study analyzes two integrated writing tasks from students in grades 6 (N=1,250) and 8 (N=1,250) using topic models. Independent evaluations of the essays were also…

In this paper, the multidigit arithmetic-related strategy adaptivity, strategy flexibility and solution accuracy of Danish compulsory school students is examined. Participants, 749 grade three, 731 grade six and 818 grade eight, were drawn from twenty demographically different schools. Drawing on a tri-phase assessment tool, each student completed…

This report characterizes forms of dialogic support that a sixth-grade teacher generated during whole-class and small-group conversations to help students develop a practice of statistical modeling. During four weeks of instruction, students constructed and revised models to account for variability and uncertainty across a variety of random…

Strategy interventions have been found to support students' text comprehension, but little is known about the sustainability of these effects. This study examined short- and long-term effects of a strategy intervention on students' vocabulary and text comprehension at the literal, inferential and evaluative levels. A pretest, posttest, and…

What can be done to promote the academic success of learners? More than a question, it is a major challenge of our time. In this perspective, metacognition seems to be a way to empower learners to take ownership of their academic success. Considering the recommendations established in the literature, we co-constructed with teachers a metacognitive…

This study aims to analyze the graphical comprehension of 5th and 6th grade students in multigrade rural primary education in Chile. The theoretical framework considers levels of reading and semiotic levels in statistical graphs. A qualitative methodology of descriptive level is followed, using content analysis method for the responses given to a…
