When conducting experiments involving the measurement of physically related quantities, choosing an appropriate spacing for the experimental independent variable is a crucial procedure whose consequences may go beyond data graphical visualization. This is particularly true if the measured quantities are nonlinearly related and experimental errors…

Psychoeducational assessment involves collecting, organizing, and interpreting a large amount of data from various sources. Drawing upon psychological and medical literature, we review two main approaches to clinical reasoning (deductive and inductive) and how they synergistically guide diagnostic decision-making. In addition, we discuss how the…

The research on the History of Mathematics and Mathematics Education has on textbook a useful tool to provide diverse types of information; this fact has led to the realization of many different studies focus on them. In this context, this work analyzes eight different sixteenth-century arithmetic books to know the different types of…

This qualitative study of 3-to-5-year-old children's hiding places and experiences is framed around the importance of recognizing children as active agents in creating their own culture and places in the world. Through the use of interactive data collection strategies collected at school and in children's homes, including book discussions,…

As technology has leaped forward to provide valuable learning tools, parents and policy makers have begun raising concerns about the privacy of student data that schools and systems have. Federal laws are intended to protect students and their families but they have not and will never be able to keep up with rapidly evolving technology. School…

Data use should be a continuous, integrated part of practice, a tool that is used all the time. Good teachers have been doing data-driven decision making all along, it just has not been recognized by that term. But there is more work to be done to ensure that educators know how to continuously, effectively, and ethically use data; that is, to help…

Although all kinds of knowledge is valuable, some non-scientific knowledge can cause confusion on students' minds. Science-pseudoscience distinction should be taught in all levels of education to protect especially young age students from this confusion. It is hard to change gained beliefs so giving importance to demarcation from elementary to…

The growth of the Internet has enabled the popularity of open online learning platforms to increase over the years. This has led to the inception of Massive Open Online Courses (MOOCs) that globally enrol millions of people. Such courses operate under the concept of open learning, where content does not have to be delivered via standard mechanisms…

This article reflects on the focus group as a research technique used in an analysis of the relationship between learning spaces and pedagogy, developed as part of the assessment of the secondary school modernisation programme in Portugal. The research proposes a methodological innovation in the use of focus group, by developing focus groups…

Next generation digital learning environments require delivering "just-in-time feedback" to learners and those who support them. Unlike traditional business intelligence environments, streaming data requires resilient infrastructure that can move data at scale from heterogeneous data sources, process the data quickly for use across…

The goal of this study is to better understand how methods for estimating treatment effects of latent groups operate. In particular, the authors identify where violations of assumptions can lead to biased estimates, and explore how covariates can be critical in the estimation process. For each set of approaches, the authors first review the…

Effectively grouping learners in an online environment is a highly useful task. However, datasets used in this task often have large numbers of attributes of disparate types and different scales, which traditional clustering approaches cannot handle effectively. Here, a unique dissimilarity measure based on the random forest, which handles the…

Purpose: Various economic growth theories propose a view of globalisation resulting in economic convergence. However, others suggest economic divergence (i.e. a widening gap between global rich and poor) and others still, different patterns of development. Hence it is necessary to validate such globalisation hypotheses with sound quantitative…

This article seeks to answer the following questions: (1) What is keeping educators from moving districts and schools to high-performing data cultures? and (2) What vital role does leadership play? Three years ago, as a senior designer and facilitator, Jennifer Unger developed a data leadership academy to address challenges for leaders, whether…

The introduction of a planetary science topic into teaching provides an opportunity for teachers to broaden the science base and offer an enrichment activity outside the National Curriculum. It enables students to undertake independent learning by engaging in a scientific investigation relevant to the real world. Here, more able students are given…
