  This study aimed to identify the role played by the professional practices done by Mathematics teachers at primary schools in the development of students’ skills in solving Mathematics problems creatively from a professional point of view. In addition, the study aimed to identify any statistically significant differences in the professional practices according to some variants (job titles, years of experience, and qualifications). To achieve the objectives of the study, the researcher used the descriptive approach in surveys. A questionnaire has been designed as a tool to collect data. The questionnaire has been proved valid, reliable and practical when responded to by a sample included 80 Mathematics teachers and supervisors at Jeddah Directorate of Education (31) educational supervisors and (49) primary teachers. The questionnaire has been analyzed and statistically processed by SPSS. The research has formulated a list of professional practices done by Mathematics teachers at primary schools to develop students’ creativity skills in solving Mathematics problems, which all were of equal high importance and came in a descending order in three axes: understanding the problem, execution planning, and generating ideas. Also, the study found that there are statistically significant differences in the responses in average for the job title (educational supervisor, teacher) variant concerning the role played by Mathematics teachers at primary schools in the development of students’ skills in solving Mathematics problems creatively in all axes and in the questionnaire as whole. In addition, there is a statistically significant difference at ≥α)0.05) between the averages of responses of professionals according to the qualifications and years of experience on the role played by Mathematics teachers at primary schools in the development of students’ skills in solving Mathematics problems creatively for both the understanding problems and generating ideas axes. There are not any statistically significant differences in the execution and planning axis. Hence, the study set a model proposal for the roles to be played and practiced professionally by Mathematics teachers at primary schools to develop students’ skills in solving Mathematics problems creatively. In the light of the study, the researcher introduced a set of recommendations and suggestions.

The research relevance is connected with the orientation of the modern model of education towards the formation of a competitive creative personality, with the need for constant self-improvement and self-development. It should be noted that the effectiveness of student learning is largely determined by the level of motivation, interest and personal participation of subjects. Therefore, the article is aimed at disclosing mechanisms for the development of students' learning motivation through a system of differentiated tasks. The leading approach to study of a problem was a personal approach, the purpose of which is to identify the issue under discussion from the point of view of dialogism, subjectivity and individuality. This document presents the characteristics of the developed and tested system of differentiated problems of mathematics, focused on the development of student learning motivation, as well as the provision of empirical data on the results of implementation. It also describes the principles on which we defined three levels of tasks in mathematics: “palgorithms”, “tasks of finding tasks” and “creative tasks”.

The study aimed to identify the difficulties of applying the continuous evaluation to the upper primary students from the point of view of the teachers in Hafr Al-Batin governorate in the Kingdom of Saudi Arabia. The study population consisted of all teachers of the upper grades in all the primary schools for the first semester of the academic year 1440/1439 AH – 2018/2019, (432) teachers. The study sample consisted of (354) teachers who responded to the questionnaire and make up 82% studying. The study data were collected using a questionnaire designed specifically for the purposes of the study. The study found that there are difficulties in the application of continuous evaluation due to the lack of incentives provided to teachers, crowded students in the classroom, and low awareness of parents of their role in the continuous evaluation. The study also recorded the absence of a statistically significant difference in the teachers' response due to the experience variable, while there is a statistically significant difference attributed to the specialization variable.

And Performance

In research focused on self-efficacy it is usually teacher-related phenomena that are studied, while the main aspects related to pupils are rather neglected, although self-efficacy itself is perceived as a belief in one’s own abilities. Evidently, this strongly influences the behavior of individuals in terms of the goal and success in mathematical problem-solving. Considering that alternative teaching methods are based on the principle of belief in one’s own ability (mainly in the case of group work), higher self-efficacy can be expected in the pupils of teachers who use predominantly the well-working pupil-centered pedagogies. A total of 1133 pupils in grade 5 from 36 schools in the Czech Republic were involved in the testing of their ability to solve mathematical problems and their mathematical self-efficacy as well. Participants were divided according to the above criteria as follows: (i) 73 from Montessori primary schools, (ii) 332 pupils educated in mathematics according to the Hejný method, (iii) 510 pupils from an ordinary primary school, and (iv) 218 pupils completing the Dalton teaching plan. In the field of mathematical problem-solving the pupils from the Montessori primary schools clearly outperformed pupils from the Dalton Plan schools (p = 0.027) as well as pupils attending ordinary primary schools (p = 0.009), whereas the difference between the Montessori schools and Hejný classes was not significant (p = 0.764). There is no statistically significant difference in the level of self-efficacy of pupils with respect to the preferred strategies for managing learning activities (p = 0.781). On the other hand, correlation between mathematical problem-solving and self-efficacy was confirmed in all the examined types of schools. However, the correlation coefficient was lower in the case of the pupils from the classes applying the Hejný method in comparison with the pupils attending the Montessori schools (p = 0.073), Dalton Plan schools (p = 0.043), and ordinary primary schools (p = 0.002). Even though the results in mathematical problem-solving are not consistent across the studies, the presented results confirm better performance of pupils in some constructivist settings, particularly in the case of individual constructivism in the Montessori primary schools. The factors influencing lower correlation of self-efficacy and performance in mathematical problem-solving ought to be subject to further investigation.

  The study aimed to identify the reality of the application of electronic supervision in public schools during the period of the Corona pandemic from the point of view of educational supervisors in the Northern Region in Jordan, depending on the changing gender and years of experience supervisory and specialization. The research adopted the descriptive analytical approach. The researcher took from (the questionnaire) a main tool to take the opinions of the members of the sample of the study consisting of 50 supervisors. The results of the research showed the reality of the application of electronic supervision in public schools during the period of the Corona pandemic from the point of view of educational supervisors in the Northern Region in Jordan at the level of the whole tool obtained a total level (3.98 out of 5) with a rating (high). At the field level: the area (barriers to the use of electronic supervision) received the highest average (4.21) rating (very high). This is followed by the field (the importance of educational supervision) where the average (3.98), the field (the application of electronic supervision in supervisory work) where the level of response was (3.91), and finally the field (the concept of electronic supervision) where the level of response was (3.80) , all are rated (high). It also showed that there were no statistically significant differences at the level of (α≤0.05) the reality of the application of electronic supervision in public schools during the corona pandemic period from the point of view of educational supervisors in the Northern Region in Jordan due to the change of gender and years of experience supervisory and specialization in all dimensions and the overall degree where the level of significance of the values (T) was greater than (0.05). The researcher recommended the adoption of integrated education in Jordanian schools, even after the Corona pandemic, to meet exceptional circumstances. The educational supervisor should develop his supervisory practices to conform to the circumstances of the Corona pandemic and to the requirements of e- learning. Finally, the teacher is supported by educational media that he or she can rely on when designing his e- lessons.

ABSTRACT The distributions of 13 variables based on 10 laboratory tests measuring thyroid function were studied in euthyroid controls and in patients with toxic diffuse or toxic multinodular goitre. Density functions were fitted to the empirical data and the goodness of fit was evaluated by the use of the χ2-test. In a few instances there was a significant difference but the material available was in some respects too small to allow a very accurate estimation. The normal limits for each variable was defined by the 2.5 and 97.5 percentiles. It appears that in some instances these limits are too rigorous from the practical point of view. It is emphasized that the crossing point of the functions for euthyroid controls and hyperthyroid patients may be a better limit to use. In a preliminary analysis of the diagnostic efficiency the variables of total or free hormone concentration in the blood proved clearily superior to all other variables.

Technology-enhanced methods of dietary assessment may still face common limitations of self-report. This study aimed to assess foods and beverages omitted when both a 24 h recall and a smartphone app were used to assess dietary intake compared with camera images. For three consecutive days, young adults (18–30 years) wore an Autographer camera that took point-of-view images every 30 seconds. Over the same period, participants reported their diet in the app and completed daily 24 h recalls. Camera images were reviewed for food and beverages, then matched to the items reported in the 24 h recall and app. ANOVA (with post hoc analysis using Tukey Honest Significant Difference) and paired t-test were conducted. Discretionary snacks were frequently omitted by both methods (p < 0.001). Water was omitted more frequently in the app than in the camera images (p < 0.001) and 24 h recall (p < 0.001). Dairy and alternatives (p = 0.001), sugar-based products (p = 0.007), savoury sauces and condiments (p < 0.001), fats and oils (p < 0.001) and alcohol (p = 0.002) were more frequently omitted in the app than in the 24 h recall. The use of traditional self-report methods of assessing diet remains problematic even with the addition of technology and finding new objective methods that are not intrusive and are of low burden to participants remains a challenge.

Linearly Polarized

Linearly polarized cylindrical waves in four-dimensional vacuum gravity are mathematically equivalent to rotationally symmetric gravity coupled to a Maxwell (or Klein–Gordon) field in three dimensions. The quantization of this latter system was performed by Ashtekar and Pierri in a recent work. Employing that quantization, we obtain here a complete quantum theory which describes the four-dimensional geometry of the Einstein–Rosen waves. In particular, we construct regularized operators to represent the metric. It is shown that the results achieved by Ashtekar about the existence of important quantum gravity effects in the Einstein–Maxwell system at large distances from the symmetry axis continue to be valid from a four-dimensional point of view. The only significant difference is that, in order to admit an approximate classical description in the asymptotic region, states that are coherent in the Maxwell field need not contain a large number of photons anymore. We also analyze the metric fluctuations on the symmetry axis and argue that they are generally relevant for all of the coherent states.

This study aimed to reveal the correlation between social intelligence and school adjustment concerning female students with learning difficulties from the perspective of female guides and teachers at the primary level in Jeddah, as well as knowing the level of social intelligence and school adjustment in addition to checking for differences between averages of the degrees of social intelligence and school adjustment among female students from the perspective of female guides and teachers due to the variable type of profession, scientific specialization and years of experience. The sample of the study consisted of (152) guides and teachers where the researcher followed the descriptive correlation method, and the scale of social intelligence and school adaptation (2020) was used by the researcher. The findings indicated a positive relationship between social intelligence and school adaptation among female students learning difficulties and they have an average level in both social intelligence and school adaptation. In addition, there are no differences between the average scoring of social intelligence and school adaptation among female students of learning difficulties from the point of view of female counselors and teachers due to the variable of profession, scientific specialization and number of years of experience. As a result of the study results, the researcher reached a number of recommendations addressed to educational institutions and female teachers and guides of general education schools applied to learning disabilities programs, which contributes to the development of social intelligence and school adaptation for female students with learning difficulties.
