Literature review shows that the development process of an achievement test is mainly investigated in dissertations. Moreover, preparing a form that will shed light on developing an achievement test is expected to guide those who will administer the test. In this line, the current study aims to create an "Achievement Test Development Process…

Representation is widely viewed as central to mathematical problem solving, while online scaffolding is considered helpful in supporting learners' progress from actual to potential developmental levels of mathematics understanding. Therefore, this study investigated the effectiveness of employing online single vs. multiple representational…

Although primary school enrollment in Pakistan has increased in the last two decades, schooling quality for girls and boys remains a central challenge. Furthermore, strides made toward gender parity are yet to address pervasive inequities in schooling outcomes. To provide insight on this matter, this paper interrogates girls' achievement in…

Shadow education helps students become academically competitive. Currently, little is known about whether shadow education can effectively fulfill either remedial or enrichment purposes in China. Using the nationally representative data from the China Education Panel Survey (CEPS) collected in 2013 and 2014, this paper explored the opportunity gap…

Covariational reasoning (or the coordination of two dynamically changing quantities) is central to secondary STEM subjects, but research has yet to fully explore its applicability to elementary and middle-grade levels within various STEM fields. To address this need, we selected a globally referenced STEM assessment--the Trends in International…

This research aimed to develop a valid and reliable test to be used to detect sixth grade students' misconceptions and errors regarding the subject of fractions. A misconception diagnostic test has been developed that includes the concept of fractions, different representations of fractions, ordering and comparing fractions, equivalence of…

Large-scale standardized tests are regularly used to measure student achievement overall and for student subgroups. These uses assume tests provide comparable measures of outcomes across student subgroups, but prior research suggests score comparisons across gender groups may be complicated by the type of test items used. This paper presents…

Predictive validity considerations in selection dictate choice of the predictor with the highest predictive validity. Implementation of this principle in any specific selection process inevitably entails choice between imperfectly correlated alternative predictors, real or hypothetical, which are equivalent in terms of predictive validity. We show…

As Bloom (1984) stated that the way to increase students' achievements with one-to-one tutorial support can be the subject of instructional technologies today. In this context, the aim of the study was to design, develop and improve a web-based dynamic assessment system aimed at contributing to mathematics learning of secondary school students.…

In this exploratory study, I investigate the relationship between age, knowledge, and creativity in mathematics, by looking at to what extent does grade level, controlled for mathematical achievement, influence mathematical creativity and what characterizes the relationship between grade level, mathematical achievement and mathematical creativity.…

The purpose of this study was to investigate the tessellation performance of 8th-grade students and factors affecting their performance. Student performances have been examined in two dimensions: identification and completion of tessellation. In this context, a diagnostic test containing two main questions with the content of determining whether…

Computer-based educational assessments often include items that involve drag-and-drop responses. There are different ways that drag-and-drop items can be laid out and different choices that test developers can make when designing these items. Currently, these decisions are based on experts' professional judgments and design constraints, rather…

This study aims to compare the performance of different small sample equating methods in the presence and absence of differential item functioning (DIF) in common items. In this research, Tucker linear equating, Levine linear equating, unsmoothed and pre-smoothed (C=4) chained equipercentile equating, and simplified circle arc equating methods…

West Africa Examination Council (WAEC) and National Examination Council (NECO) are the two major examination bodies saddled with the responsibility of awarding Senior Secondary School Certificate in Nigeria. This study examined the comparability of the psychometric properties of the items constructed by the two examination bodies using Item…

Grade inflation is pervasive in American high schools. Is rampant grade inflation cause for concern? How teachers' grading standards affect student success is an empirical question--one that the author addresses in this article in a new study of roughly 350,000 North Carolina students taking Algebra I between 2006 and 2016. The author first…
