The importance of mathematics is common knowledge, and teachers have always been concerned with teaching this subject correctly and efficiently. For this reason, teaching mathematics should be given special attention, and even the base and frameworks should be provided for online teaching of this subject. This study aims to introduce mathsframe.co.uk as a platform for online teaching of mathematics. The present study tried to turn the challenges facing online mathematics teaching into opportunities for better instruction. The method of research was descriptive and a case study (in-depth). The facilities and games of the website were divided into categories of Most popular free mathematics games, Tablet friendly games, Word problems, Using a calculator, Money, Sorting and classifying, National curriculum, Addition and subtraction, Fractions, decimals and percentages, Measuring and time, Partitioning, place value and rounding, Latest mathematics games, Multiplication and division, Ordering, comparing and reading numbers, Geometry, Statistics and ITPs. There are games and options in these categories which are suitable to teach and exercise subjects like money, reading and working with different types of charts, numbers divisible to a certain number and prime numbers, decimals, measuring angles, numbers axis, exercising and learning different math operations, multiplication table, comparing numbers, showing the number of shapes and categories, counting numbers, place value chart, measuring volume, ratio, possibility, fraction, the method of transferring numbers in technical addition and subtraction, symmetry, measuring mass and temperature, coordinates, clock, working with a ruler, volume and perimeter. Many math instruction games and options complementary to teachers' teaching are free, and there is no need for signing up, entering information or paying a fee; but a basic knowledge of English is required for teaching or exercising elements of the categories.

Learning can only maintain its functional originality when it leads to permanent changes, and such changes are only possible if accompanied by self-explanation. The current study was conducted to investigate the effect of self-explanation and the solved examples on students’ transfer, intrinsic motivation, and cognitive load in English courses. It was an experiment in the form of a 2×2 generalized random block design. The population consisted of all 8th-grade students in Semnan, Iran, from whom 120 students were selected applying random sampling – by considering a figure for each student, writing each figure on a piece of paper, putting all inside a pack, mixing them together, and drawing one piece out each time to get 120 candidates. Teaching English was done using the “Solved Examples” method. The instruments applied  to collect the data included the Intrinsic Motivation Questionnaire by Kuvaus and Dysvik (2009), the Cognitive Load Questionnaire by Paas and van Merrienboer (1993), and the researcher-made questionnaire of near and far transfer. The statistical analysis of the data was conducted using the Two-way Analysis of Variance (ANOVA). The findings indicated that the format of presenting content (ordinary and erroneous solved examples) and self-explanation are correlated significantly with the near and far transfer, cognitive load, and intrinsic motivation (P<0.01). Based on the obtained results, it can be argued that self-explaining and presenting solved examples are useful strategies to enhance students’ transfer, intrinsic motivation, and cognitive load in learning English, and can be included in the curriculum of schools to empower students in solving intellectual problems.  

Purpose : The aim of present research was identifying the effective components on managing the challenges of thesis writing based on the lived experiences of PhD students in Islamic Azad University. Methodology : This study in terms of purpose was applied and in terms of implementation method was phenomenological from type of qualitative. The research population was students and graduates of the PhD period of humanities fields at the Islamic Azad University in 2020-21 academic years. The research sample according to the principle of theoretical saturation was determined 12 people which were selected by purposive sampling method. Data were collected by semi-structured interviews whose validity by 15 professors was obtained by the relative content validity coefficient method 0.866 and its reliability by the Holsti coefficient method was obtained 0.865. Finally, the data were analyzed by open, axial and selective coding method in MAXQDA-18 software. Findings : The results showed that for managing the challenges of thesis writing based on the lived experiences of PhD students were identified 67 indicators in 13 sub-components and 3 main components. The main components were included administrative-organizational solutions (with three sub-components of maximum use of virtual systems, modification of the thesis doing process and financial assistance), solutions (with three sub-components of increase study, proper planning and strengthening skills) and educational strategies Conclusion : The results of this study have practical implications for graduate officials and planners, and they can use the identified components to properly manage the challenges of thesis writing and improve them in the higher education system.
