Feedback on how students progress through completing subgoals can improve students' learning and motivation in programming. Detecting subgoal completion is a challenging task, and most learning environments do so either with "expert-authored" models or with "data-driven" models. Both models have advantages that are…

The quality of exams drives test-taking behavior of examinees and is a proxy for the quality of teaching. As most university exams have strict time limits, and speededness is an important measure of the cognitive state of examinees, this might be used to assess the connection between exams' quality and examinees' performance. The practice of…

Research has shown that tape diagrams are beneficial for algebra learning. However, it is unclear whether certain visual features of tape diagrams have implications for learning. We investigated, with undergraduate students and math teachers, whether tape diagrams with different visual features (color, presence of outer lines, and position of the…

Machine learning has achieved state-of-the-art performance in many areas, including image recognition and natural language processing. However, there are still many challenges and mysteries attracting numerous researchers. This dissertation comprises a series of works concerning problems at the intersection of computer science theory, adversarial…

Educational content labeled with proper knowledge components (KCs) are particularly useful to teachers or content organizers. However, manually labeling educational content is labor intensive and error-prone. To address this challenge, prior research proposed machine learning based solutions to auto-label educational content with limited success.…

This dissertation explored questions related to teaching graphing skills to graduate students in behavior analysis. In Study 1, a survey of BCBAs asked which graphing conventions behavior analysts are most likely to revise. Only five conventions received high overall agreement and differences in revision ratings were associated with demographic…

The Doctor of Education (EdD) degree is vital in preparing individuals for leadership positions in educational settings. A key element of the EdD program is the faculty's proficiency in their specific fields of expertise. Assessing the faculty's mastery of subject matter is crucial for guaranteeing the quality of education and offering students a…

Technology-driven shifts have created opportunities to improve efficiency and quality of assessments. Meanwhile, they may have exacerbated underlying socioeconomic issues in relation to educational equity. The increased implementation of technology-based assessments during the COVID-19 pandemic compounds the concern about the digital divide, as…

Spatial analytics receive increased attention in educational data mining. A critical issue in stop detection (i.e., the automatic extraction of timestamped and located stops in the movement of individuals) is a lack of validation of stop accuracy to represent phenomena of interest. Next to a radius that an actor does not exceed for a certain…

Contributions: This article presents the findings of a study on the impact of instructional interventions (training and additional requirements and prompts) to improve the quality of students' self-and-peer assessment in a capstone engineering technology course. Background: Historically, students in this course inflated rating values in comparison…

The forced-choice (FC) item formats used for noncognitive tests typically develop a set of response options that measure different traits and instruct respondents to make judgments among these options in terms of their preference to control the response biases that are commonly observed in normative tests. Diagnostic classification models (DCMs)…

Transparency and trustworthiness are among the key requirements for the ethical use of learning analytics (LA) and artificial intelligence (AI) in the context of social inclusion and equity. However, research on these issues pertaining to users is lacking, leaving it unclear as to how transparent and trustworthy current LA tools are for their…

Context: Students with special educational needs in the area of learning (SEN-L) attend vocational trainings to be provided with qualifications for the labor market. Competences in arithmetic operations and comparing quantities such as weights and lengths are indispensable for obtaining a vocational qualification. Therefore, the study investigates…

This study examined the effectiveness of an ultrasound visual biofeedback (UVB) training on speech-language pathology (SLP) students' assessment of sonographic tongue configuration. This study examined the presence of a functional relation between an ultrasound visual biofeedback (UVB) training within the Participatory Adult Teaching Strategy…

To evaluate the teaching effect of problem-based learning (PBL) combined with lecture-based learning (LBL) compared with that of LBL alone in renal pathology education for trainees receiving standardized training. A total of 65 undergraduate medical students who received standardized training in Xijing Hospital from January 2016 to November 2019…
