Effectiveness of Self-Explanations Strategy in Developing Physical Concepts and Awareness of future envisioning of secondary stage students: فاعلية استراتيجية التفسيرات الذاتية في تنمية المفاهيم الفيزيائية والوعي باستشراف المستقبل لدى طلاب المرحلة الثانوية

Thesis Objectives: The thesis aimed at investigating the effectiveness of using Self-Explanations Strategy in developing physical concepts and the awareness of future envisioning of secondary stage students. To achieve the research objectives, the quasi-experimental approach was used through applying the experiment to two groups (the control and the experimental groups). The sample comprised (51) students; (25) at first secondary term students in the experimental group and (26) students in the control group. Thesis procedures: The scientific content of chapter seven, entitled "gravity" in the physics textbook for the first secondary grade students (second term), was structured and organized according to the philosophy and nature of Self-Explanations Strategy. Then, two tools were prepared; the physical concepts test and the awareness of future envisioning scale. The Validity and reliability of the two tools were applied through applying them on a pilot group of (30) students. They were pre-applied, then the experimental group was taught using Self-Explanations Strategy and the control group was taught using the traditional method. Then, the thesis tools were post-applied to get the raw scores to apply the statistical processing in order to get the results. Thesis results: The results revealed the effectiveness of Self- Explanations Strategy in in developing physical concepts and the awareness of future envisioning. Whereas there statistically significant differences at (a≤0.05) level were existed between the mean scores of the control and the experimental groups students in the post test of concepts as well as the future awareness scale in favor of the experimental group.

Ovary Structure and Oogenesis of Trypophloeus klimeschi (Coleoptera: Curculionidae: Scolytinae)

The female reproductive system, ovary structure and ultrastructure of Trypophloeus klimeschi (Coleoptera: Curculionidae: Scolytinae) were investigated using light microscopy, scanning electron microscopy, and transmission electron microscopy. Its female reproductive system is comprised of two ovaries (each ovary has two ovarioles), lateral oviducts, common oviduct, spermathecal sac, spermathecal pump, two accessory glands and bursa copulatrix. Well-developed endoplasmic reticulum can be clearly seen in the secretory cells of spermathecal sac. This species has telotrophic meroistic ovarioles that are comprised of terminal filament, tropharium, vitellarium and pedicel. The terminal filaments are simple; each is comprised of cellular peritoneal sheath. The presence of several clusters of nurse cells in the tropharium is indicative that its ovarioles conform to the transition stage. This indicates that there are at least two different types (transition stage and secondary stage) of ovarioles in Curculionidae.

EFL Learners’ Perceptions Regarding the Use of Busuu Application in Language Learning: Evaluating the Technology Acceptance Model (TAM)

After the exceptional circumstances the whole world has experienced due to the COVID-19 pandemic, students have become digital natives who seek learning that overcomes the barriers of place and time. This mixed-methods study aimed at investigating EFL learners' perceptions regarding the application of Busuu in language learning, by applying the Technology Acceptance Model (TAM). The participants were 58 first secondary stage students in a Saudi private school. An online survey and a semi-structured interview were used to collect data. The results revealed that EFL learners have a positive attitude towards Mobile Assisted Language Learning (MALL).  Additionally, according to the TAM, the participants found the language application Busuu useful and easy to use. They also thought of Busuu as a valuable resource for language learning, which increases their motivation to be autonomous learners. However, in addition to the TAM components, the results also showed that affordance and joyfulness could be strong indicators of learners' acceptance of a particular technology.  Moreover, the results revealed that mobile applications might be more helpful for beginner learners than advanced ones. On the other hand, the findings also showed that Busuu might distract learners from doing their homework. Besides, the regular use of Busuu might be harmful to their eyes due to the small mobile screen size. For further research, the recommendation includes a large sample size in addition to a long-term study of EFL learners' perception towards Busuu in normal classroom circumstances.

The main results indicate that three institutions are the protagonists in management. The Secretariat of Higher Education, Science, Technology and Innovation (SENESCYT), the Council for Quality Assurance in Education (CACES) and the Council of Higher Education (CES). Higher education is one of the main drivers of societal evolution. Investing in education is vital to ensure a prosperous and competitive socioeconomic system. Higher education has a high responsibility to society: they are responsible for preparing the professionals of the future.

A Critical Evaluation of NCERT Mathematics Textbook of Senior Secondary Stage

The aim of the mathematics curriculum at the senior secondary stage is to provide students with an appreciation of the wide variety of the application of mathematics and equip them with the basic tools that enable such application. A careful choice between the often conflicting demands of depth versus breadth needs to be made at this stage. The rapid explosion of mathematics as a discipline, and of its range of application, favors an increase in the breadth of coverage. Such an increase must be dictated by mathematical considerations of the importance of topics to be included. Topics that are more naturally the province of other disciplines may be left out of the mathematics curriculum. The treatment of topics must have an objective, that is, the communication of mathematical insights and concepts, which naturally arouse the interest and curiosity of students.

Knowledge Economy Skills and their Relationship to Mathematical Culture among Secondary School Mathematics Teachers
