Diluting a system with metal complexes can sometimes cause free metal ions to increase in concentration. This paper describes "metal ion anti-buffering", a situation in which free metal ion concentrations rapidly increase as system dilution drives dissociation. It only occurs under excess free ligand conditions when a solution is…

This dissertation consists of five chapters. The first chapter serves to introduce the Modern Learning Environment (MLE) by discussing the challenges of designing and measuring student performance in these novel environments. Chapter two of the dissertation reviews the current research base of studying self-regulated learning in the modern…

Exploiting the free technology empowering services with which Google supplies the educational field, the present paper contributes a Google Education mediated syllabus framework to the field of teaching English as a second/ foreign language. Through a systems approach methodology, the framework addressed the concepts of 'learner autonomy' and…

MathCheck is a relatively new online tool that gives students feedback on their solutions to elementary university mathematics and theoretical computer science exercises. MathCheck was designed with constructivism learning theory in mind and it differs from other online tools as it checks the solutions step by step and shows a counter-example if…

Researchers have long supported the use of dictation as a test for language learners (Fountain & Nation, 2000), and dictation has been used as a test for learners of English as a foreign language (EFL). With the advantages of productive learning and reinforcing short-term memory, dictation is a commonly used technique to develop language…

This study examines the available literature on the effects of serious games on people with intellectual disabilities or autism spectrum disorder. The studies were categorized based on the limitations in skills that these people address. Fifty-four studies were selected, from different data sources. These studies address limitations in…

While support exists in the literature for the efficacy of computer-assisted instruction (CAI), possible dosage effects have rarely been investigated. Kindergarten students enrolled in a public school district in Idaho were randomly assigned on the class level to an experimental or control condition during the 2017-2018 school year. Students in…

Background: Engaging students in computer-assisted guided inquiry learning has great potential to scaffold their scientific understanding: Students are expected to improve their scientific problem-solving skills, and at the same time gain a deep conceptual understanding of the subject-matter. Additional generative activities such as creating video…

Digital technology plays a crucial role in modern second/foreign language education. Enormous changes in technology and the growing emphasis on 21st century skills raise a concern about English as a foreign language (EFL) teachers' competencies in computer-assisted language learning (CALL) more than ever. In response to the mounting concern, this…

This paper reports a case study of 20 university peer tutor-tutee dyads which engaged in online synchronous peer tutoring using MENTOR, a mobile application developed to support peer tutoring. Despite years of research, peer tutoring still attracts significant attention and an emerging area of research is online peer tutoring. This study aimed to…

Digital technologies have been widely used to enhance language learning, the effectiveness of which has been acknowledged in the literature. With the rapid development of digital devices and technologies, increasing technologies have been used in the most recent several years, leading to more diversified approaches to language education. This…

This study investigated the experiences and perceptions of two instructors while designing, teaching, and evaluating a flipped, intermediate Spanish course. Qualitative data was gathered through pre-post semi-structured interviews, curriculum design documents, class observations, and student course evaluations. The findings revealed that beliefs…

We present a study in which multimedia alphabet books were constructed for ten languages using the Learning And Reading Assistant (LARA) platform. We describe the alphabet books we built, the different design features they instantiate, and an initial evaluation using an anonymous online questionnaire. Links are provided to the books themselves,…

Computer-assisted instruction (CAI) programs are considered as a way to improve learning outcomes of students. However, little is known on the schools who implement such programs as well as on the effectiveness of similar information and communication technology programs. We provide a literature review that pays special attention to the existing…

This study explored how students viewed the role of ideas for knowledge work and how such a view was related to their inquiry activities. Data mainly came from students' online interaction logs, group discussion and inquiry, and a survey concerning the role of ideas for knowledge work. The findings suggest that knowledge building was conducive to…
