In 2022-23, Round Rock Independent School District in Texas rebranded the Response to Intervention (RTI) as Multi-tiered Support System (MTSS). The purpose of this report is to assess the effect of MTSS on staff data literacy, MTSS implementation, and elementary school student achievement. We used a mixed-method approach, including analysis of…

This handbook has been conceived as a guide for young researchers embarking on the exciting journey of investigating different aspects of plurilingual education. The text can also serve to review ideas previously encountered, and perhaps as a means of interrogating research methodologies in plurilingual contexts for those who already have ample…

This article focuses on an analysis of trends in the "Journal of Positive Behavorial Interventions" ("JPBI") since its inception. The primary emphasis is on the variables that contributed to the origin of the journal. Key researchers and other professionals felt that there was a need for a new field (with a new journal) in…

Aim: The main aim of this commentary was to connect the insights from the contributions of the special issue on the intersection between depth and the regulation of strategy use. The seven contributions in this special issue stem from three perspectives: self-regulated learning (SRL), model of domain learning (MDL), or the student approaches to…

Purpose: Evidence from past surveys suggests that some interviewees simplify their responses even in very well-organized and highly respected surveys. This paper aims to demonstrate that some interviewers, too, simplify their task by at least partly fabricating their data, and that, in some survey research institutes, employees simplify their task…

In this paper, Signild Vallgårda (SV) investigates why a ban against the use of industrially produced trans fatty acids in foods was introduced in Denmark as the first country in the world. SV correctly states that our part of, and activity in that process, represent a combination of scientific work and 'policymaking'. We, however object to some…

In this ITEMS module, we provide a two-part introduction to the topic of reliability from the perspective of "classical test theory" (CTT). In the first part, which is directed primarily at beginning learners, we review and build on the content presented in the original didactic ITEMS article by Traub and Rowley (1991). Specifically, we…

New materialist and posthuman research methodologies are quickly gaining traction in educational research. According to its proponents, new materialism takes us to radically new places of praxis as it reconfigures central notions such as data, researcher positioning and critique. Here I consider how the notion of 'data' is invoked in an example of…

A distinction is made between scores as measures of a construct and predictions of a criterion or outcome variable. The interpretation attached to predictions of criteria, such as job performance or college grade point average (GPA), differs from that attached to scores that are measures of a construct, such as reading proficiency or knowledge…

Data literacy has become an important part of STEM literacy and informed citizenship in our society. However, data literacy initiatives in secondary schools predominantly focus on narrow issues of developing students' ability to work with quantitative data and fail to address students' broader understanding both as producers and consumers of data.…

An improvement of the experiment with a driven pendulum is proposed: during a run, the phase shift between the driving force and displacement is continuously displayed vs. frequency. The method of phase measurements is taken from the lock-in detection technique. Using the new PASCO data acquisition system, the measurements in a frequency range…

The increasing use of digital systems to support learning leads to a growth in data regarding both learning processes and related contexts. Learning Analytics offers critical insights from these data, through an innovative combination of tools and techniques. In this paper, we explore students' activities in a MOOC from the perspective of personal…

We explore 11-12-year-old students' emerging ideas of models and modelling as they engage in a data-modelling task involving inquiry based on data obtained from an experiment. We report on a design-based study in which students identified what and how to measure, decided how to structure and represent data, and made inferences and predictions…

Statistics is one of the important branches of mathematics taught in schools, colleges and universities. It is also an important tool in public policy discussions. This paper focuses on the use of statistics in the latter context, rather than its use in adult mathematics education research. I review the key characteristics of the statistical…

As intersectionality gains more prominence, scholars still face difficulties of incorporating principles of intersectionality into empirical research. Key concepts of intersectionality theory include moving away from additive thinking, relationality, and social constructionism. An important challenge is how to incorporate these concepts into…
