Rethinking pedagogy through storytelling in school mathematics
Authors: Nepal Kamal , Shrestha Indra Mani
Published: August 2023

This article focuses on storytelling as an alternative innovative pedagogical approach to teaching mathematics in response to a discipline-based pedagogy in the context of Nepali Mathematics Education. In Nepal (probably worldwide), mathematics teachers rarely teach mathematics for creating mathematics. Instead, they focus on teaching the steps to repeat someone else's creation without exploring how mathematics relates to students' life worlds. As a result, students feel mathematics as a dry subject, mathematics teachers as apathetic human beings and mathematics classrooms as a boring factory of producing passive learners. In this context, this paper explores how storytelling may become one of the many innovative mathematics pedagogies and help mathematics teachers rethink their pedagogical practices for teaching mathematics joyfully and meaningfully. We used autoethnography as a research methodology that portrayed the narratives of the first author extracted from his MPhil research based on storytelling pedagogy and the narratives of the second author based on his experiences of teaching the course at the post-graduate level and conducting teacher professional development training across Nepal. The research inquiry explored the connections of mathematics with students' life worlds through storytelling as a pedagogical approach.

Authors: ÇEMÇ Muhammed Sıddık , YILMAZ Hasan Hüseyin , KALDIRIMCI Murat
Published: August 2023

This study aims to evaluate the risk of traumatic brain injury by comparing data obtained from elite active boxers and healthy individuals through the application of the Symbol Digit Modalities Test and the Trail Making Test, which are sensitive to brain damage, as well as the Verbal and Nonverbal Cancellation Test, which is sensitive to the right parietal lobe. The study is conducted with eight male boxers with an average age of 19.3±2.60 years, who had an average of 7.25±3.41 years of active boxing experience, and ten healthy males with an average age of 19.7±1.05 years, who had no involvement in any combat sport. The Kruskal-Wallis Test was employed to investigate the difference between the groups based on the data obtained from the Symbol Digit Modalities Test and the Trail Making Test, while the Mann-Whitney U test was used to evaluate the difference between the groups in the data from the Verbal and Nonverbal Cancellation Test. Upon evaluating the results of the Symbol Digit Modalities Test, the control group scored significantly higher on the SDMT-1, SDMT-2, and SDMT-3 than the boxers. The results of the Trail Making Test showed that the control group completed the TMT1-A, TMT1-B, TMT2-A, and TMT2-B forms faster than the boxers, but the differences in these times were not statistically significant. In the context of neuropsychological tests, active boxers exhibited lower neurocognitive performance compared to healthy individuals

Tevhidlerde Allah’ın zat, sıfat ve fiillerinden bahsedilerek O’nun varlığı, birliği, tek ve eşsiz oluşu, yüceliği gibi konular üzerinde durulur. Kelam ilminin inceleme sahasına giren bu mevzular, şiir dairesinde vezin, kafiye ve sanat endişesinden kaynaklı olarak ilmî olmaktan ziyade edebî bir hüviyet kazanmakta, her biri müstakil birer madde gibi beyitlere dağılmaktadır. Birçok tevhid manzumesinde ilmî bir plan dairesinde olmasa da edebî bir form içerisinde Allah’ın varlığının ispatına dönük ifadelere sıkça yer verildiği gözlenmektedir. Kelam âlimlerinin isbat-ı vacib için başvurdukları kanıtlardan biri olan gaye ve nizam delili de bunlardan biridir.

El objetivo de este artículo es explorar el paso de la educación cívica tradicional como puente hacia la educación ambiental, destacando la importancia de enseñar competencias ciudadanas relacionadas con el medio ambiente. El estudio se basó en una revisión exhaustiva de la literatura existente sobre educación cívica y educación ambiental (particularmente relacionada con los proyectos ambientales educativos [PRAE]), y se examinaron algunos proyectos desarrollados por instituciones educativas en Colombia que promueven el aprendizaje de competencias ciudadanas con un enfoque en la conciencia y la responsabilidad ambiental. Los resultados revelaron que la educación cívica tradicional centrada en aspectos políticos y legales de la ciudadanía estaba evolucionando hacia un enfoque más amplio, que incorporaba la educación ambiental. Los programas de educación ambiental demostraron ser efectivos para fomentar la participación ciudadana activa en la resolución de problemas ambientales, al tiempo que promueven valores como la sostenibilidad y la justicia social. En conclusión, al enseñar competencias ciudadanas relacionadas con el medio ambiente, se empodera a los ciudadanos para que participen en la toma de decisiones informadas y se conviertan en agentes de cambio positivo en su comunidad y en el mundo en general.
Selected Human Resource Management Practices and Employee Retention: A Case of Deposit Taking Microfinance Institutions in Nairobi, Kenya
Authors: Mwangi June W. , Kombo Henry K.
Published: August 2023

Retention of employees is increasingly becoming a real challenge in organizations. While past studies have demonstrated the importance of employee retention in organizations, few have empirically examined the effect of human resource management practices on employee retention. The overall objective of this study was to examine the effect of selected human resource management practices on employee retention in deposit-taking microfinance institutions in Nairobi, Kenya. Specifically, the study sought to establish the effect of career development, learning, and development on employee retention in deposit-taking microfinance institutions in Nairobi, Kenya. A census survey of twelve (12) licensed deposit-taking microfinance institutions was conducted in the study. The study adopted an explanatory research design. The target population comprised 320 employees from the institutions’ headquarters in Nairobi. Stratified sampling was used to select the respondents from different departments of the licensed deposit-taking microfinance institutions. Primary data was collected using a structured questionnaire. The data was summarized using the mean and standard deviation. Pearson’s correlation was used to examine the relationship between career development, learning and development, and employee retention. Simple and multiple regression analyses were used to test the research hypotheses. Pearson correlation results revealed that career development and employee retention (r = 0.161, p value 0.002) were positively and significantly correlated, with a significant positive correlation between learning and development and employee retention (r = 0.672, p < 0.000). Further, regression analysis results show that career development, learning, and development have a significant effect on employee retention. The study also revealed that career development, learning, and development have a significant effect on employee retention. The study recommends that to enhance employee retention, organizations need to invest in career development, learning, and development.
Technical note: On HALOE stratospheric water vapor variations and trends at Boulder, Colorado
Authors: Remsberg Ellis
Published: August 2023

Abstract. This study compares time series of stratospheric water vapor (SWV) data at 30 and 50 hPa from 1993 to 2005, based on sets of Halogen Occultation Experiment (HALOE) profiles above the region of Boulder, CO (40∘ N, 255∘ E), and on local frost-point hygrometer (FPH) measurements. Their differing trends herein agree with most of the previously published findings. FPH trends are presumed to be accurate within their data uncertainties, and there are no known measurement biases
affecting the HALOE trends. However, the seasonal sampling from HALOE is
deficient at 40∘ N from 2001 to 2005, especially during late
winter and springtime, when HALOE SWV time series at 55∘ N clearly
show a springtime maximum. This study finds that the SWV trends from HALOE
and FPH measurements nearly agree within uncertainties at 30 hPa for the more limited
time span of 1993 to 2002. Yet, HALOE SWV at 50 hPa has significant and
perhaps uncertain corrections for interfering aerosols from 1992 to 1994.
Northern Hemisphere time series and daily SWV plots near 30 hPa from the
Limb Infrared Monitor of the Stratosphere (LIMS) experiment indicate that
there is transport of filaments of high SWV from polar to middle latitudes
during dynamically active winter and springtime periods. Although FPH
measurements sense SWV variations at all scales, the HALOE time series do
not resolve smaller-scale structures because its time series data are based
on an average of four or more occultations within a finite latitude–longitude sector. It is concluded that the variations and trends of HALOE SWV are reasonable at 40∘ N and 30 hPa from 1993 to 2002 and in accord with the spatial scales of its measurements and sampling
frequencies.
Assessing sampling and retrieval errors of GPROF precipitation estimates over The Netherlands
Authors: Bogerd Linda , Leijnse Hidde , Overeem Aart , Uijlenhoet Remko
Published: August 2023

Abstract. The Goddard Profiling algorithm (GPROF) converts radiometer observations aboard Global Precipitation Measurement (GPM) constellation satellites to precipitation estimates. Analyzing the accuracy of GPROF’s estimates is vital to further improve the algorithm. Such analyses often use high-quality ground-based estimates as reference with a different spatial resolution. Often, the reference is resampled to match the satellite’s resolution. However, the implemented sampling method to simulate the satellite’s resolution varies amongst studies, which limits the transferability of conclusions. additionally, GPROF combines observations from various sensors and frequency channels, each with its own footprint size. Hence, uncertainties related to sampling are added on top of the uncertainty introduced when converting brightness temperatures to precipitation intensities. The contribution of sampling to the total amount of uncertainty remains unknown. Here, we quantify the uncertainty related to sampling while analyzing the current performance of GPROF over the Netherlands during a four year period (2017–2020). In this area, shallow and light precipitation frequently occur. Both precipitation types are often subject to research, as both types are difficult to detect with space-borne sensors. Only GPROF estimates based on observations from the conical-scanning radiometers of the GPM constellation are used. We investigate the uncertainty related to sampling by simulating the reference precipitation as satellite footprints that vary in size, geometry, and applied weighting technique. The reference estimates are gauge-adjusted radar precipitation estimates from two ground-based weather radars from the Royal Netherlands Meteorological Institute (KNMI). Echo top heights (ETH) retrieved from the same radars are used to classify the precipitation as shallow, medium, or deep. The method used to spatially average the reference into a satellite footprint, i.e. using Gaussian weighting or the arithmetic mean, is found to exhibit a minimal influence on the retrieved estimate. The size of the sampled area is found to be the most influential. Still, the effect of using different footprint sizes cannot explain all the differences between the ground- and satellite based precipitation estimates. Additionally, the discrepancies between GPROF and the reference are largest for low ETH, while the relative bias between the different footprint sizes and implemented weighting methods increase with increasing ETH. Lastly, our results do not show a clear difference between coastal simulations and simulations over land. We conclude that the uncertainty introduced by merging different channels and sensors cannot fully explain the errors introduced by the retrieval algorithm. Hence, retrieval errors are found to be more prominent than sampling uncertainties, in particular for shallow and light precipitation.
A Simulation Approach to Characterizing Sub-Glacial Hydrology

Published: August 2023

Abstract. The structure and distribution of sub-glacial water directly influences Antarctic ice mass loss by reducing basal shear stress and enhancing grounding line retreat. A common technique for detecting sub-glacial water involves analyzing the spatial variation in reflectivity from an airborne ice penetrating radar (IPR) survey. Basic IPR analysis exploits the high dielectric contrast between water and most other substrate materials, where a reflectivity increase ≥ 15 dB is frequently correlated with the presence of sub-glacial water. There are surprisingly few additional tools to further characterize the size, shape, or extent of hydrological systems beneath large ice masses. We adapted an existing radar backscattering simulator to model IPR reflections from sub-glacial water structures using the University of Texas Institute for Geophysics (UTIG) Multifrequency Airborne Radar Sounder with Full-phase Assessment (MARFA) instrument. Our series of hypothetical simulations modeled water structures from 5 m to 50 m wide, surrounded by bed materials of varying roughness. We compared the relative reflectivity from rounded Röthlisberger channels and specular flat canals, showing both types of channels exhibit a positive correlation between size and reflectivity. Large (> 20 m), flat canals can increase reflectivity by more than 20 dB, while equivalent Röthlisberger channels show only modest reflectivity gains of 8−13 dB. Changes in substrate roughness may also alter observed reflectivity by 3−6 dB. All of these results indicate that a sophisticated approach to IPR interpretation can be useful in constraining the size and shape of sub-glacial water, however a highly nuanced treatment of the geometric context is necessary. Finally, we compared simulated outputs to actual reflectivity from a single IPR flight line collected over Thwaites Glacier in 2022. The flight line crosses a previously proposed Röthlisberger channel route, with an obvious bright bed reflection in the radargram. Through multiple simulations, we demonstrated the important role that topography and water geometry can play in observed IPR reflectivity. We ultimately conclude the bright reflector from our IPR flight line is more likely a broad area of wide distributed water, such as a series of flat canals or sub-glacial lake, instead of a Röthlisberger channel. The approach outlined here has broad applicability for studying the basal environment of large glaciers, and can aid in constraining the geometry and extent of sub-glacial hydrologic structures.
Disentangling the Hydrological and Hydraulic Controls on Streamflow Variability in E3SM V2 – A Case Study in the Pantanal Region

Published: August 2023

Abstract. Streamflow variability plays a crucial role in shaping the dynamics and sustainability of Earth's ecosystems, which can be simulated and projected by river routing model coupled with land surface model. However, the simulation of streamflow at large scales is subject to considerable uncertainties, primarily arising from two related processes: runoff generation (hydrological process) and river routing (hydraulic process). While both processes have impacts on streamflow variability, previous studies only calibrated one of the two processes to reduce biases in the simulated streamflow. Calibration focusing only on one process can result in unrealistic parameter values to compensate for the bias resulted from the other process, thus other water related variables remain poorly simulated. In this study, we performed several experiments with the land and river components of Energy Exascale Earth System Model (E3SM) over the Pantanal region to disentangle the hydrological and hydraulic controls on streamflow variability in coupled land-river simulation. Our results show that the generation of subsurface runoff is the most important factor for streamflow variability contributed by runoff generation process, while floodplain storage effect and main channel roughness have significant impacts on streamflow variability through the river routing process. We further propose a two-step procedure to robustly calibrate the two processes together. The impacts of runoff generation and river routing on streamflow are appropriately addressed with the two-step calibration, which may be adopted by Land Surface Model and Earth System Model developers to improve modelling of streamflow.
Regional analysis of convective heavy rain events in the German State of Hesse
Authors: Perschke Manuel , Schmalz Britta , Ruiz Rodriguez Ernesto
Published: August 2023

Abstract. The convective heavy precipitation events, which occur primarily in the summer months, cannot be recorded representatively by ground-based precipitation stations due to their frequently small spatial extent, short life span and high rapidly changing intensity. The radar network of the German Weather Service, on the other hand, records area-wide, spatiotemporally highly resolved precipitation information that enables comprehensive identification of precipitation objects. In this study, a method for the identification, description and classification of convective precipitation objects considering a flood-relevant event extent is presented. Assuming an orographic independence of the events in the Central European low mountain range, the German State of Hesse is chosen as representative study area. Considering the spatial and temporal extent of the identified events, the most extreme expression is selected and independence is ensured. With the assignment of an authoritative duration for the intensive main rainfall phase, an extensive collection of heavy precipitation objects results. The results show a characteristic event length of 15 to 60 minutes; longer durations are underrepresented and exhibit inhomogeneous extreme value behavior. Statistically, the generated samples can be well represented and classified by the generalized extreme value distribution. The evaluation allows us to make a regional characterization of convective heavy precipitation.

Abstract. The hydroxyl radical (OH) largely determines the atmosphere’s oxidative capacity and, thus, the lifetimes of numerous trace gases, including methane (CH4). Hitherto, observation-based approaches for estimating the atmospheric oxidative capacity have primarily relied on using methyl chloroform (MCF), but as the atmospheric abundance of MCF has declined, the uncertainties associated with this method have increased. In this study, we examine the use of five hydrofluorocarbons (HFCs) (HFC-134a, HFC-152a, HFC-365mfc, HFC-245fa and HFC-32) in multi-species inversions, which assimilate three HFCs simultaneously, as an alternative method to estimate atmospheric OH. We find robust estimates of OH regardless of which combination of three HFCs are used in the inversions. Our results show that OH has remained fairly stable during our study period from 2004 to 2021, with variations of <2 % and no significant trend. Inversions including HFC-32 and HFC-152a (the shortest-lived species) indicate a small reduction in OH in 2020 (1.6 % ± 0.9 % relative to the mean over 2004–2021 and 0.6 ± 0.9 % lower than in 2019), but considering all inversions, the reduction was only 0.5 ± 1.1 % and OH was at a similar level to that in 2019.

THE RELATIONSHIP BETWEEN THE HISTORICAL DEVELOPMENT OF MUSTARD GARDEN SHAN SHUI AND CHINESE TRADITIONAL CULTURE
Authors: Wang Chao , Ni Xuqian
Published: August 2023

Landscape holds an important position in the entire history of Chinese painting. Since the Wei and Jin Dynasties, there have been many unique Shan shui. Although the characteristics of landscape styles vary in different periods and genres are diverse, the freehand brushwork spirit and artistic conception of traditional Chinese landscapes have always permeated through them. Chinese traditional landscape is a kind of art form with national characteristics and Zeitgeist connotation gradually formed through historical evolution in the process of social development and progress. This paper will start with the development process of mustard landscape and the inheritance of traditional culture, study the impact of mustard landscape on traditional culture, Zeitgeist, industry and self personality, and explore the innovative development path and significance of Chinese contemporary landscape. Relevant studies not only analyzed the reasons why landscape was widely spread in China, but also profoundly revealed the relationship between mustard garden landscape and Chinese traditional culture, and concluded that mustard garden Shan shui not only inherits Chinese culture, but also has a profound impact on Chinese culture and Chinese people's spirit, with solid theoretical research value and historical research value.
Modification of zeolite Na-X, sodalite and cancrinite in salt melts
Authors: Stanimirova Tsveta , Kirov Georgi
Published: August 2023

The possibility of occlusion in melts of useful components of some of the most economically advantageous materials, obtained during zeolitization of fly ash – Na-X, sodalite and cancrinite, was investigated. A very high degree of occlusion of ZnCl2 in zeolite Na-X was achieved along with complete exchange of Na extra framework cations with Zn2+. By elution, it was proved that, in the interaction of zeolite Na-X with ZnCl2 melt, occlusion takes place without destroying the zeolite aluminum-silicate framework. In a KNO3 melt, in the narrowest pore structure – the sodalite structure, occlusion does not proceed, only ion exchange occurs. Through computer modeling, the ion exchange of both the charge-balancing cations and the synthetically incorporated cation-anion pairs has been proven. The interaction of cancrinite-SO4 with a KNO3 melt results in the formation of a material with an altered cationic composition and occluded KNO3, which gradually comes out of the structure upon elution. The results obtained in the work can be a basis for the development of future applications of the modified minerals as materials with antibacterial properties (occluded ZnCl2 in the structure of zeolite Na-X) and as slow-acting fertilizers or micro-fertilizers (occluded with KNО3 cancrinite and sodalite forms).

Energy consumption leads to an energy crisis and environmental problems. Energy-saving consumption is of great significance to reduce energy consumption. Based on the stimulus-organism-response (S-O-R) framework, this research introduces perceived value and positive emotion and constructs a model in which green advertising affects consumers’ energy-saving consumption. Meanwhile, based on congruity theory, this research explores the influence of self-image congruity. A field study was adopted, and a total of 413 questionnaires were collected. The results show that green advertising receptivity positively affects perceived value, positive emotion, and purchase intention. Self-image congruity moderates the relationship between green advertising receptivity and perceived value, but it has no moderating effect on the relationship between green advertising receptivity and positive emotion. On this basis, the contributions of this research and further research prospects are discussed.
Optimizing convergence for dual-credit policy and carbon trading in the automobile sector: A bi-layer planning model

A growing call has been made to convert the dual-credit policy to carbon trading to further unleash the carbon reduction potential of the automobile sector as China’s dual-carbon strategy progresses. However, controversy exists in academia about the convergence timing of the two policies. Therefore, this paper builds a bi-layer planning model to show the interaction between government policies and automakers’ production and R&D decisions, based on which to explore the optimal decision on carbon trading’s introduction timing and carbon quotas. The results show that the current is not the optimal time to bridge the two policies considering the price difference between carbon pricing and credits. Interestingly, we find that the reduction in carbon emissions per vehicle for new energy vehicles and conventional fuel vehicles has an opposite effect on the optimal timing of the introduction of carbon trading. Moreover, a comparison of the impact of new energy vehicle profits and carbon prices on the timing of introduction shows the former has a greater impact on the adoption of carbon trading in the automobile sector.

It explains the two concepts that are similar in nature by discussing who is a legitimate child and who is an illegitimate child; it also discusses the legal implications of an illegitimate child and that of legitimate child. It discusses the rights and privileges of a legitimate child and also those of an illegitimate child. The article discusses the statuses of illegitimate child under Islamic law, statutory law, customary law, and under void marriage and voidable marriages. It goes further to discuss the provision of Section 42 (2) of the 1999 constitution of the Federal Republic of Nigeria (as amended) viz-a-viz the status of illegitimate children. The work reviews some relevant cases to the topic. It concludes by summarizing that it could be deduced that before a child could be regarded as legitimate, he or she must be a product of a valid marriage. However, the case of acknowledgement did not take this into consideration. The article recommends that the Legitimacy Act be made less stringent, that the date of legitimation should be made effective from the date of birth and not the date of legitimation and that the constitution should be amended to include punishment for whoever discriminates or make derogatory remarks about an illegitimate child, among others.

The Digital Human Modelling (DHM) method, in which the anthropometric characteristics of humans are represented using a computer-aided three-dimensional model, is used in many different ergonomic optimisation applications, especially in areas such as manufacturing, machine utilization, assembly simulation, cabin design, human-robot communication. This method aims to identify and reduce potential ergonomic risks in posture and work positions during the design phase by simulating human-machine interactions in digital environments.Thus, possible injuries and injuries can be prevented. Especially in critical aviation applications where operator safety is vital, functionality and ergometry analyzes are important in cockpit and console designs. In this study, ergonomic analyzes of the operator consoles in an air support aircraft were carried out according to the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) methods, according to two different postures, using the Human Builder and Human Activity Analysis modules in the CATIA V5 sofware. In Position-1, the operator's situation of directly looking at the screen and reaching for the screen buttons is considered, while in Position-2, the operator's situation of reaching for the tablet located on the side and looking at the screen below has been evaluated from an ergonomic perspective. Additionally, angle of view analyses have been performed for these two postural positions.

This study focuses on investigating the effect of process parameters on the tensile strength of PLA and iron-reinforced PLA samples produced using FDM technology. Filament material (PLA and iron-reinforced PLA), infill ratio (20, 40 and 60%), layer thickness (0.1, 0.2 and 0.3 mm), printing speed (40, 60 and 80 mm/s) and raster angle (30, 45 and 60°) were selected as process parameters. The experimental design was based on the Taguchi L18 index. Signal-to-Noise (S/N) ratio, variance analysis (Anova) and regression analyses were used to statistically analyze the tensile strength values obtained as a result of experimental measurements. The outcomes of this study show that the filament material plays an important role in tensile strength and iron reinforcement to PLA material decreases the tensile strength and increases the % elongation. The maximum tensile strength was measured as 33.55 MPa at 60% infill rate, 0.3 mm layer thickness, 60 mm/s printing speed and 60° raster angle in PLA filament material, which is the optimum process parameters.

In a learning activity, an individual is an actor in determining the success of the learning process. Learning results will be less than maximum when there is no awareness, will, or involvement of students in learning. As a student should be able to take responsibility for what he has done and not rely on others to do the task, every student should have an attitude of learning independence. This study aims to be able to know: 1) the relationship between independence of learning and the results of learning Arabic in Nashrul Haq Al-Islamy; 2) the independence of studying in Pondok Pesantren Nashrul Haq Al-Islamy; and 3) the results of studying Arabic at Nashral Haq El-Iislamy. The quantitative approach used in this study is correlational. The study involved a sample of 49 cells. Data is then collected using an analytical research instrument. Of the 30 statements tested first, only 20 could be validated, with a reliability value of 0.814. The results of the study of students at the Nashrul Haq Al-Islamy Training Hall showed that learning independence was at a high score of 80, while learning results were in the middle category of 79. The relationship and significance between the independence of learning and the results of learning Arabic in Nashrul Haq Al-Islamy are in a very low category. It is that the correlation value is 0.047 and the significance value is 0.747, which means more than 0.05 (0.747>0.05). Based on the results of the study, H1 in this study was rejected. Therefore, there is no significant connection between independent learning and the results of learning Arabic in the Nashrul Haq Al-Islamy Residence

Today, many people are interested in studying Arabic, seeing the urgency of Arabic as a solution to various complex problems in modern times. Many educational institutions participate in developing and implementing Arabic language learning, both formal and non-formal. One of these educational institutions is the Al-Ashriyyah Islamic Boarding School Nurul Iman Parung Bogor, which established an Arabic language LKP in Parung Bogor. This research is a field research (field research) in the form of qualitative research using a multidisciplinary approach which includes, among others: pedagogical, normative theological, juridical, sociological, and psychological approaches. The results of this study suggest that LKP Nurul Iman Arabic conducts Arabic courses for students who wish to deepen and further develop their Arabic language skills through non-formal institutions specifically established for the development of Arabic. The Arabic language learning system at LKP Nurul Iman Arabic is a non-credit Arabic learning program run by the Language Development Institute for all students who are interested in learning Arabic further. LKP Arabic Nurul Iman has not been equipped with standard curriculum references, syllabi, and manuals, teaching materials are tentative/change according to management policies every year. The learning model is designed simultaneously on the same day and hour in each class, it is not allowed to shift teaching hours or days by the teacher, this course program also does not make the class the only learning center. LKP Arabic Nurul Iman has succeeded in improving students' Arabic language skills, and has also succeeded in producing sufficiently qualified Arabic language experts. The increased achievement of Arabic competitions at the Al Ashriyyah Nurul Iman Islamic Boarding School, such as Arabic speech contests, Arabic debate competitions, Taqdimul Qisshoh and others, both at the district and national levels, is evidence of the increased students' Arabic language skills
