This study investigates sixth-grade students' explorations of tessellations with Scratch through the mathematical aesthetics. For this purpose, the study analyzed the students' explorations by considering the roles of mathematical aesthetics identified by Sinclair (2004): generative, evaluative, and motivational role. Six middle-school students…

In this paper, we extend our previous work on challenges teachers face when engaging with proportional reasoning contexts to investigate two contexts that included four problems for middle grades teachers to solve as well as eight student solutions. Analysis included coding for correct solving of the problem as well as making sense of and…

This study focuses on proportional division, a specific problem type of proportions and proportional relationships, which embeds a part-part-whole relationship. We investigated how students in grades 6 to 9 solved and perceived three proportional division problems. Analysis of the students' performance on the tasks revealed three types of…

This article is on pedagogical translanguaging, understood as planned instructional strategies used with a pedagogical purpose in a multilingual educational context. The paper reports a study on cognate identification and cognate awareness carried out in a multilingual primary school. The study aims at analyzing whether the identification of…

The goal of this study was to examine how students process formative feedback that included corrective and elaborative information in online question-answering tasks. Skilled and less-skilled comprehenders in grade 8 read texts and answered comprehension questions. Prior to responding, students were asked to select the textual information relevant…

This study examined the effects of collaborative dialogue in learning the speech act of request. Seventy-four second-grade girls' junior high students were divided into three groups. The "collaborative group" (n = 25) received explicit metapragmatic information on request (request head act and modifications) followed by a dialogue…

To be an informed citizen in today's information-rich environment, individuals must be able to evaluate information they encounter on the Internet. However, teachers currently have limited options if they want to assess students' evaluations of digital content. In response, we created a range of short tasks that assess students' "civic online…

The purpose of this case study was to describe how one band director used pedagogical content knowledge while working with beginning-band students to help them develop the skill of playing brass lip slurs. Data were generated from (1) video recordings of each class over two different weeks during the school year, (2) "think aloud"…

The study explores the development of 11-year-old students' informal inference about random bunny hops through student talk and use of computer simulation tools. Our aim in this paper is to draw on dialogic theory to explain how students make shifts in perspective, from intuition-based reasoning to more powerful, formal ways of using probabilistic…

This study investigated the effects of the use of scaffolds in written classroom assessments through the voices of both native English speakers and English language learners from two middle schools. Students responded to assessment tasks in writing, by speaking aloud using think aloud protocols, and by reflecting in a post-assessment interview.…

Spatial visualisation is a subset of spatial ability and is exemplified in predicting whether or not a net will fold to form a target solid. The researchers examined video of interviews to explore the schemes of Year 5 students for determining the validity of nets for a cube and pyramid. Findings suggest the significance of imaged actions, shown…

We conducted a qualitative research of case studies based on think-aloud protocols. The aim was to carry out in-depth analyse secondary students' cognitive difficulties appearing in early stages of transfer processes in problem-solving. The task was to relate several source problems to a target problem, in order to solve it effectively. Source and…

Several studies found that direct instruction and task structuring can effectively promote children's ability to design unconfounded experiments. The present study examined whether the impact of these interventions extends to other scientific reasoning skills by comparing the inquiry activities of 55 fifth-graders randomly assigned to one of…

This study examined the social and cognitive interaction patterns of third, fourth, and fifth graders as they collaboratively read on the Internet and responded to an inquiry prompt. Data analysis revealed patterns of cognitive strategy use that intersected with social forms and functions of dialogue. Dyads that exhibited higher levels of…
