The studies in this dissertation were conducted to better understand how to measure students' use of multiple representations in introductory science courses by expanding the possibilities of a variable representation assessment (VRA). The VRA is a computer-based assessment originally designed to measure general chemistry students' use of…

Quality control (QC) in testing is paramount. QC procedures for tests can be divided into two types. The first type, one that has been well researched, is QC for tests administered to large population groups on few administration dates using a small set of test forms (e.g., large-scale assessment). The second type is QC for tests, usually…

The modern web-based technology greatly popularizes computer-administered testing, also known as online testing. When these online tests are administered continuously within a certain "testing window," many items are likely to be exposed and compromised, posing a type of test security concern. In addition, if the testing time is limited,…

Few would argue about the growing importance of information and communication technology (ICT) literacy as relatively new and distinct skills that affect educational attainment, workforce readiness, and lifelong learning. There is less agreement, however, as to what ICT literacy skills and knowledge are, how best to measure them, and strategies…

This article reports on an experimental study on the acquisition of prepositional relative clauses in second language European Portuguese by Chinese native speakers. It focuses on the role of resumption, mandatory in prepositional relative clauses in Chinese (the native language of the learners) and non-conventional in European Portuguese (the…

This study attempts to explain a systematic phenomenon that has been described in interlanguage grammars crosslinguistically: Null-Prep, which consists of omitting the obligatory preposition in certain movement constructions. We propose that Null-Prep is not related to lack of knowledge of "wh"-movement, as previously assumed, but to…

This study reports syllable position effects on second language (L2) Portuguese speech perception, revealing that L2 segmental learning may be prone to an influence from the suprasegmental level. The results show that first language (L1) Mandarin learners had diminished performance on the discrimination between the target Portuguese liquids (/l/…

During the COVID-19 pandemic, Cooperative Extension professionals, like many others, were tasked with quickly adapting to accommodate limited face-to-face interactions. The pandemic necessitated that Extension educators leverage online resources to deliver tailored programming in informative and innovative ways while providing engaging, hands-on…

The aims of the study are to construct an online instrument to assess different aspects of morphological awareness and to examine its development and its relation to reading comprehension in grades 2-4 in Hungarian children. Altogether, 4134 students were tested. The online test evaluated inflectional, derivational, and compound morphological…

The aim of this experiment was to determine if dyad practice helped individuals become aware, use, and retain information in a dynamically changing perceptual-motor task compared with practice alone. We used a computerized perceptual-motor task, where individuals were required to intercept balls that dropped from the top of the screen. A colored…

Objectives: Volunteering promotes well-being and may provide added purpose to life after retirement. Limited evidence exists regarding the characteristics and study adherence among those who participate in longitudinal studies while also volunteering outside the study. We assessed characteristics and adherence of older adults who volunteered…

This study implemented the principles of dynamic assessment (DA) with computer technology, iSpring Quiz Maker, to (1) identify the English listening difficulties of 172 L2 English learners; (2) diagnose their individual learning needs, and (3) promote their future potential abilities. Upon evaluating the participating junior high school students'…

Purpose: This paper aims to investigate the major challenges faced and lessons learned during the unplanned transition to online examinations (OE) at a traditional university following the COVID-19 pandemic. Design/methodology/approach: This exploratory study involved two distinct samples (110 students and 30 instructors) drawn from a large public…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction on math achievement, as measured by SBA scores. We compared "striving learner" students who were assigned to use i-Ready Personalized Instruction (Treatment students) and "striving learner" students assigned to only receive i-Ready…

This article describes the evolution and current state of the domain-independent Siette assessment environment. Siette supports different assessment methods--including classical test theory, item response theory, and computer adaptive testing--and integrates them with multidimensional student models used by intelligent educational systems.…
