Following psychologist Langer's theory, this study aimed to examine the influence of conditional tasks containing inherent uncertainty on the cultivation of mindfulness. It used preceding research to develop conditional mathematics tasks corresponding to integers and rational numbers, within a 10-lesson curriculum. It divided a total of 182 middle…

Using a randomized controlled trial, we investigated changes in both sexual harassment (SH) perpetration and victimization of 2104 middle school students in New York City who received divergent saturation and dosage levels of "Shifting Boundaries," an SH prevention program, which was represented by the length of the program. We assessed…

This study explored the effects of explicit and implicit epistemologically enhanced instructions probing 9th-grade students' personal epistemologies on their physics-related personal epistemology (PPE) and physics achievement in the heat and temperature unit. In the implicit epistemologically enhanced instruction (IEEI), different dimensions of…

This quantitative study examined the impact school mentors have on the attendance of 15 male fourth and fifth grade students. Student attendance data were collected to compare the students' absences in the 2021-2022 school year versus the 2022-2023 school year. This data was analyzed to determine whether there was a difference in the attendance…

The need to modernise school physics to encompass the fundamentals of Einsteinian physics is widely recognised. While the ability of students to comprehend qualitative Einsteinian concepts has been demonstrated, little information exists to determine the best student age and the duration of instruction required for introducing Einsteinian physics…

The level of arithmetic knowledge of a high school student was explored when solving additive word problems considering the semantic structure and syntactic component. The methodology was qualitative and developed in four stages: the first is the selection of the participant, the second is the design of a questionnaire with twenty additive…

This study draws on a research project where a model of fiction-based ethics education was developed and put into practice during a school year in five classes in compulsory school, two in grade 5 and three in grade 8. A test was constructed with the purpose of evaluating a multi-dimensional ethical competence. The test was given at the beginning…

The purpose of this study is to determine the opinions and self-efficacy beliefs of middle school students towards mathematical connections before and after the process in a learning environment prepared in the context of connections with different disciplines and including modeling tasks. An embedded experimental mixed method design was used in…

A textbook is of a proper medium for conveying curricular values to students. The aim of this study is to examine how math textbooks reflect the core values stated in the curriculum. Selected by homogeneous sampling technique, the data sources of this qualitative study consisted of two (one official and one private) fifth-grade math textbooks. All…

The present study aimed to examine children's and adults' performance and strategies in volume estimations. Three tasks were designed and presented to 40 adults and 40 6th grade children who were asked to estimate: (a) the number of unit measures (bricks/rice spoons) that may be put in a container, (b) the quantity of bricks/rice, between two…

Visual comparisons are pervasive in science, technology, engineering, and mathematics (STEM) instruction and practice. In previous work, adults' visual comparisons of simple stimuli were faster and more accurate when the layout of a display facilitated alignment of corresponding elements--the "spatial alignment principle" (Matlen et al.,…

The professional lexicons of middle school mathematics teachers in communities around the world were documented as part of The International Classroom Lexicon Project. This vocabulary captured teachers' naming of classroom pedagogical practice. Reported in this paper are attributes of the lexicons of teachers from Australia and Chile. A comparison…

This study examined the effect of a supplemental, multicomponent reading intervention with 75 seventh graders who scored below grade level according to a battery of assessments. Students received a yearlong reading intervention during the 2021-2022 or 2022-2023 school year. Students' pretest and posttest data were compared to determine the impact…

Previous research suggests that environment can play an important role in encouraging or discouraging creative expression and productivity. Additional research has uncovered a discrepancy between the creativity students express at school and the creativity they express outside of school. The fact that, in previous research, students expressed more…

This paper outlines the design and application of a didactic sequence aimed at facilitating primary students' understanding of axial symmetry, utilizing a combination of digital artefacts and paper tasks. We wondered to what extent the designed didactic sequence is able to make primary school students formulate and validate effective programming…
