In any meta-analysis, it is critically important to report the dispersion in effects as well as the mean effect. If an intervention has a moderate clinical impact "on average" we also need to know if the impact is moderate for all relevant populations, or if it varies from trivial in some to major in others. Or indeed, if the…

There is a strong connection between word reading and spelling development. Students' spelling can provide insights into their word-level reading skills and inform intensive reading interventions delivered within a data-based individualization framework. The purpose of this article is to describe the linguistic knowledge bases that connect word…

Background: Although it is well established that students' adaptive reactions towards errors promote learning outcomes, little is still known about the role of error feedback in promoting these reactions. Aim: Through a targeted intervention based on an online teaching unit, this study aimed at testing whether supportive error feedback promotes…

Students with reading disabilities require instruction and intensive intervention targeted to their current learning needs. Through data-based instruction, educators can monitor student's performance and make adjustments to instruction to better address student needs using both progress monitoring and diagnostic assessment. This article provides…

This study aims to identify the phonological error patterns of normally developing children who speak colloquial Jordanian Arabic dialect and to provide normative data for the age of suppression for each phonological error pattern. One hundred fifty-four normally developing children (68 females and 86 males) ranging from 3 to 6.5 years were…

Many U.S. students possess only a weak knowledge of fraction arithmetic. I hypothesize that textbooks are a critical reason for students' poor performance on fraction arithmetic. This is not because of what textbooks contain but rather because of what they lack. Distributions of fraction arithmetic problems in textbooks are imbalanced, with…

Students with extensive support needs are at risk of demonstrating challenging behavior due to inadequate support of their individual needs or class-wide factors such as low quality of instruction. Students with extensive support needs are also among the students who are most likely to experience aversive interventions and be placed in segregated…

Teachers' ability to accurately judge difficulties of mathematical tasks is an essential aspect of their diagnostic competencies. Although research has suggested that pedagogical content knowledge (PCK) is positively correlated with the accuracy of diagnostic judgments, experimental studies have not been conducted to investigate how PCK affects…

This study aimed to evaluate the effectiveness of a remedial teaching intervention in improving learners' understanding of trigonometric equations. Using a mixed methods exploratory case study design, a purposive sample of 24 Grade 11 learners from a rural school in the Eastern Cape province participated in the intervention. The research involved…

Studying towards a postgraduate qualification is viewed as a booster that may usher employees towards management positions. We have found common mistakes in research proposals for master's degree students in a department at the University of Namibia. Our presentation shows the shortcomings in the research proposals of postgraduate students and…

Presenting novel numbers about climate change to people after they estimate those numbers can shift their attitudes and scientific conceptions. Prior research suggests that such science learning can be supported by encouraging learners to make use of given benchmark information, however there are several other numerical estimation skills that may…

This study examines high school students' beliefs about studying English, particularly their perceptions of language intelligence, aptitude, and age sensitivity in language learning. A total of 87 Year 12 students from a boys' school in Northeastern Thailand voluntarily participated in a pre-and post-intervention online language mindset…

Developing effective oral business English (OBE) curricula requires clearly understanding student needs. This study evaluated the speaking needs of Chinese English as a Foreign Language (EFL) undergraduates majoring in business English for specific purposes (ESP), aiming to inform the design of a teaching module that bridges the gap between…
