As technology tools, such as MyOpenMath, MyLab Math, RStudio, and Python become increasingly integrated into college-level mathematics instruction, it is essential to understand how students perceive and interact with these platforms. Many students struggle with confidence using computers and anxiety, which can hinder their ability to fully engage…

This dissertation describes an experiment to investigate how learners with different levels of background in computer science learn core concepts of computer science, in particular, algorithms. We designed a study to focus on cognitive task analysis for eliciting the empirical mental elements of learning two graph algorithms. Cognitive workload…

Computer-based assessments is becoming more and more common in mathematics education, and because the digital media entails other demands than paper-based tests, potential threats against validity must be considered. In this study we investigate how preparatory instructions and digital familiarity, may be of importance for test validity. 77 lower…

In the realm of language proficiency assessments, the domain description inference and the extrapolation inference are key components of a validity argument. Biber et al.'s description of the lexicogrammatical features of the spoken and written registers in the T2K-SWAL corpus has served as support for the TOEFL iBT test's domain description and…

A key piece of a validity argument for a language assessment tool is clear overlap between assessment tasks and the target language use (TLU) domain (i.e., the domain description inference). The TOEFL 2000 Spoken and Written Academic Language (T2K-SWAL) corpus, which represents a variety of academic registers and disciplines in traditional…

The purpose of the current study was to develop and validate the Pre-Service Teacher Online Teaching Motivation Scale (PST-OTMS), a survey instrument designed to reliably measure motivational constructs related to online teaching and learning in pre-service teachers. Due to increasing opportunities to teach within online learning contexts where…

In this study, I investigated the effectiveness of a creativity-support system that I developed in the level editor of a learning game called "Physics Playground" on improving college students' creativity. Moreover, I investigated the validity and reliability of an in-game assessment of creativity to measure students' creativity.…

The purpose of this study is to explore the validity of the assessment tool. The purposive sampling method is applied in this research on a total of 551 preschool children between 4 and 6 years old. Their ages range from 46 to 81 months, with an average age of 63.9 months (SD = 7.58). The assessment tool used in this research is the…

The increasing attention on Chinese as a foreign language (CFL) pronunciation instruction gives us an opportunity to look into the current directions of teaching CFL and the specific instructional pronunciation strategies employed by CFL teachers. This paper offers a review of empirical evidence on the use and impact of instructional pronunciation…

Purpose: This study presents the competence level of education students in College Geometry and the development of a Computer Generated Instructional Materials (CGIM). Method: This research used the model for research and development by Borg and Gall (2003) with revision. The researchers developed a CGIM, specifically, the worktext paired with…

The main purpose of this study was to develop an instrument that assesses university students' perceived readiness for computer-supported collaborative learning (CSCL). Assessment in CSCL research had predominantly focused on measuring "after-collaboration" outcomes and "during-collaboration" behaviors while…

Screening and monitoring student reading progress can be costly and time consuming. Assessment embedded within the context of online instructional programs can capture ongoing student performance data while limiting testing time outside of instruction. This paper presents two studies that examined the validity of using performance measures from a…

In this paper I explore how Margaret Beier, Lesley Miller, and Shu Wang make claims for the validity and reliability of the instrument they developed to explore the construct of "possible selves" as described in their manuscript, "Science Games and the Development of Scientific Possible Selves."

Researchers have been keen to develop instruments for the assessment of teachers' self-perceived technological pedagogical content knowledge (TPACK); however, few studies have been conducted to validate such assessment tools through students' perspectives in the context of English as a foreign language (EFL). The purpose of this study was thus to…

A few computer-assisted language learning (CALL) instruments have been developed in Iran to measure EFL (English as a foreign language) learners' attitude toward CALL. However, these instruments have no solid validity argument and accordingly would be unable to provide a reliable measurement of attitude. The present study aimed to develop a CALL…
