English Language Learner Teachers’ Perceptions Of Digital Games On Student Learning

This body of work contains three articles that examine the intersectionality between English Language Learner (ELL) teachers and digital games. The purpose of the study is to qualitatively explore the perception of ELL teachers’ use of digital games as educational tools and whether they realize the potential to promote language learning for ELLs. This study aims to understand the lived experiences of ELL teachers to identify their viewpoint of language learning through gaming. The work focuses particularly on the teacher in an effort to contribute empirical work that supports the need for a more holistic approach to digital games in teacher education programs. This dissertation sought to answer four main questions: 1) What is the perception and lived experiences of ELL teachers use of digital games as educational tools?; 2) What are the perceived challenges facing ELL teachers in incorporating digital games?; 3) How does ELL teacher’s perception of digital games influence their use and incorporation?; 4) How do ELL teachers define best practices for digital games in order to promote language learning? I employed qualitative case study methods with a phenomenological lens to analyze the data. I interviewed six ELL teachers in the upper Midwest of the United States. The outcome of this study has the potential to enable teachers to use digital games effectively and to ultimately improve teaching and learning. Today, almost every aspect of society requires the use of technology. Therefore, the incorporation of technology into lesson plans is aligned with the needs of society in the 21st century. By adding digital games into classroom learning, educators may be able to better prepare students for their future careers. This preparation can be achieved because digital games have the potential to increase students’ problem-solving skills, as well as spatial and logical reasoning. The upward mobility and learning opportunities in digital games for ELLs are multiplied in fun and engaging ways

Designing and Publication of Interactive E-Book for Students of Princess Nourah bint Abdulrahman University: An Empirical Study

The present study aims to keep pace with the rapid developments in the field of e-learning which includes the widespread use of e-books. Therefore, the authors conducted a pilot study on (55) faculty members from various disciplines, they assured the importance of e-books in education and the need for them. Accordingly, the authors designed and published their book "Education Technology: Foundations and Applications" as an interactive application on apps platforms by using a design model that was developed by the authors, and by adopting a list of (28) standards divided into four domains to ensure the quality of the design and development of the e-book according to educational and technological standards. Thereafter, female students’ perceptions of the effectiveness of e-books and their self-efficacy in using it were identified by (44) female students of Princess Nourah bint Abdulrahman University. The results indicate that the students have the basic skills necessary to download and read e-books and take advantage of its characteristics, additionally, they believe in its usefulness and are satisfied with it as they intend to continue using e-books in the future.

Semantic openness in the plastic arts

The semantic openness constitutes the mirror that reflects the imagination and intellectual creativity through awareness and perception and the openness of the borders between cultures and ideas in the effectiveness of invention that appears between contemporary plastic arts, which gives freedom for artists to express and diversify their artistic trends and their acquisition of experiences, and study the concept of openness and its impact on the formation of artistic achievement and the study of semantics And its multiplicity in the formal structure. The openness of the visual text to multiple readings and different connotations. Therefore, we find interpretation contributes to the production of creative texts, and from here the research attempts to be free from commitment to one meaning; therefore, the semantics varied, and the text became open and transgressive to other texts, which leads to the textual openness through the overlapping of texts and the multiplicity of readings. This research aims to know the semantic openness in the plastic arts (painting, sculpture, and ceramics) that includes an artistic product based on a related text with open connotations

Students’ Difficulties in Solving Physics Problems in Introductory College PhysicsCourses at King Saud University

The purpose of this study was to identify the difficulties facing students in introductory college physics courses at King Saud University in solving physics problems, by exploring faculty members' perceptions of these difficulties, and through analyzing students' answers to physics problems in final exams. The study mainly focused on four themes of difficulties, including: the problems verbal context, physics laws, mathematical skills and graphs or diagrams. The study also sought to learn about faculty's perception towards the degree of influence of the proposed solutions. The study sample consisted of 27 physics faculty members, in addition to 391 students. The study showed consistency between the faculty members' perception towards the difficulties of solving problems and the analysis of student answers in final exams. The difficulties related to the verbal context were the most common among students, whereas difficulties related to mathematical skills were the least common. In addition, the results revealed that there were also difficulties related to physical laws, and knowledge of graphs or diagrams. The findings showed that the perceptions of faculty members towards proposed solutions as being as a “high effect”on fourteen suggested techniques, while their perception towards the rest of the techniques were as “medium effect”. Finally, their perception towards only one technique was being of “low effect"

The design of a resistive switching characterisation platform based on discrete current-conveyors

In this paper we propose a current-conveyor based circuit to characterise resistive switching devices. The circuit relies on open-loop current-mode techniques that are in principle faster than existing solutions that rely on transimpedance amplifiers for biasing and current sensing [1]. The circuit is able to apply a voltage across a test device and simultaneously provide a measure of current flowing through it. The circuit therefore, results in a compact solution that can be scaled-up to characterise crossbar devices in parallel. In this paper we describe, simulate and evaluate a discrete version of the proposed circuit. We also verify a PCB implementation that is capable of forming, writing and reading different types of resistive switching devices

Elevation resolution enhancement in 3D photoacoustic imaging using FDMAS beamforming

Photoacoustic imaging is a non-invasive and non-ionizing imaging technique that combines the spectral selectivity of laser excitation with the high resolution of ultrasound imaging. It is possible to identity the vascular structure of the cancerous tissue using this imaging modality. However, elevation and lateral resolution of photoacoustic imaging is usually poor for imaging target. In this study, three dimension filter delay multiply and sum beamforming technique (FDMAS(3D)) is used to improve the resolution and enhance the signal to noise ratio (SNR) of the 3D photoacoustic image that is created by using linear array transducer. This beamforming technique showed improvement in the elevation by 36% when its compared with three dimension delay and sum beamforming technique (DAS(3D)). In addition, it enhanced the SNR by 13 dB compared with DAS (3D)
