This study aims to investigate students' speaking anxiety in English classes in the second semester of Universitas Borneo Tarakan. Specifically, this study examines the factors that influence students' speaking anxiety and strategies to minimize it based on what the students have experienced. Thirty-eight students were selected as research subjects using a specialized sampling method. The researchers used a descriptive qualitative method with a phenomenological approach by conducting interviews, questionnaires, and observations with students who have anxiety in speaking English. The results showed two factors, including internal factors, i.e., discouragement (feeling shy), lack of confidence, and fear of making mistakes, and external factors (limited vocabulary and friends/classmates). And there are two strategies shown in this study (preparation and relaxation). The conclusion of this study is that speaking anxiety can occur and hinder students' speaking performance. Therefore, strategies are needed to do so in order to make it easier for students to speak.

A systematic mapping review of the implementation of the Sustainable Development Goals (SDGs) in higher education has been carried out. Forty-six articles published from 2018 to 2022 were identified using the Systematic Literature Review. The purpose of this literature review was to derive a research framework that effectively raise awareness of SDGs from the realm of higher education and show SDGs research opportunities that have not been widely implemented. Research findings in the implementation of SDGs innovation in higher education have a trend in the categories of learning, stakeholders (institutions), teaching and approach. Based on the five modalities of higher education, the category is spread over the aspects of education (79%) and knowledge production (10%). The other three aspects such as public debate, provision of public services and embodiment only have quantities below 5%. Innovations include the development of SDGs-based courses by integrating aspects of knowledge production and provision of public services into one learning goal through the Project-based Learning Model. Mapping of the implementation of the SDGs in higher education provides information that supports researchers, educators and policy-making institutions interested in educational innovation. The results of the analysis show that the integration of these aspects can not only increase the understanding of higher education graduates regarding the SDGs but also increase public awareness regarding the SDGs through the provision of public services by universities.

This research aims to explore the paradigm of applying learning by doing to create active learning in Islamic education. A combination of both quantitative and qualitative methods was used in this study. Data collection begins with qualitative data and continues with quantitative data. This flow is also known as exploratory sequential design. The study's findings indicate that the use of learning by doing in Islamic education creates a supportive and adaptable learning environment where students can develop their critical thinking, collaboration and communication skills through firsthand experience and other people's teachings. Second, learning by doing has a positive influence on students in Islamic education. The findings of the quantitative data analysis in the test (paired sample t-test) demonstrate a substantial difference between the results before and after implementing learning by doing performance-based learning. The degrees of freedom (dk), the magnitude of which is N-1 as well as 40-1 = 39 are the basis for determining the value of the t-table. The value of degrees of freedom 39 at a significant level of 5% is obtained by t-table 1.684. The results can be obtained with a count greater than the t-table namely 16,701 > 1,684and Sig. (2-tailed) = 0.000 < 0.05 based on the results of the analysis of the t-test (paired sample t-test). So, it can be concluded that learning by doing can improve the ability to think creatively, logically, systematically and critically.

Mastery of mathematical literacy is essential for developing life skills in the 21st century. Mathematical literacy is even more critical in elementary schools as it forms the basis for mastery at the junior and senior high school levels. Elementary school students differ in their characteristics from students at the higher education level. They, therefore, require an appropriate learning model to improve their mathematical literacy. This research aims to develop a learning model, termed Realistic Mathematics Engineering (RMEng), that combines the Realistic Mathematics Education approach with the steps of the Engineering Design Process and determines the model's effectiveness. The model was validated by seven experts from three universities in Indonesia and had an Aiken validity index value of 0.786, indicating that it was valid. The RMEng model contains the following steps: understanding realistic problems, solving problems in informal ways, developing formal mathematics, developing products, and drilling. Discussions and presentations can be incorporated into each of these five steps. The RMEng model was subjected to the stages of preliminary and main field testing and was revised based on the suggestions of teachers and observers. Through experimental research compared to a control group, the RMEng model was proven more effective in increasing elementary school students' mathematical literacy at the 0.000 significance level.

The purpose of this study is to investigate the position of women in Terengganu's copra industry between 1900 and 1941. Coconut is one of the major crops traditionally farmed in Terengganu, and during this time period, excess coconuts were dried, smoked, and grated to become copra. In Terengganu, the copra sector was intimately linked to women, who were innovators creating a variety of coconut-based food and non-food products, including soap, cooking oil, traditional desserts, and more. Nevertheless, prior studies have mostly disregarded the creative role that women played in Terengganu's copra sector during this time. Studies on women from Terengganu have instead concentrated on handicrafts, rice farming, commerce, and fishing. This historical study highlights women's creative innovation and also examines the importance of copra as a crucial export commodity of the state. In addition to secondary sources, primary sources for this project included archival files from the State Secretary of Terengganu, CO 840/1 (Terengganu Administrative Reports, 1910-1930), CO. 840/2 (Terengganu Administrative Reports, 1931-1940), the National Archives of Malaysia, and the National Archives of Kew Garden in London. The results show that in the early 20th century, Malay women made noteworthy contributions to Terengganu's copra sector. As a result, the Terengganu government acknowledged the production of copra as a vital export during this period. Keywords: Malay women, Terengganu, Copra industry, Early-20th-century Malaya, Working women, Agriculture, Cottage Industries, Introduction This paper discusses the historical roles of women in the early-20th-century economy of the Malay Peninsula. It highlights the traditional division of tasks between men and women while emphasizing [...]

Adolescence is a critical phase that can cause a problem, one of which is violence. This condition is detrimental to the dynamics of school academic activities. School counselors are one of the parties who have a central role in developing peace-loving characters to suppress student violence. This research is a systematic literature review that describes the role of counselors as agents of peace whose primary focus is to build peace in students in the school environment through social sensitization strategies based on the teachings of KH Ahmad Dahlan. Systematic literature review searches and reviews various articles using search engines of reputable article journals. The study reviewed ten articles with the following procedure steps: identification, screening, eligibility, and included. The data analysis of this research used data extraction. The results showed that the counselor could use a social sensitization strategy containing the teachings of KH Ahmad Dahlan. The peace values of KH Ahmad Dahlan include sincerity, humility, critical thinking, tolerance, and compassion. This paper discusses the operational description of a social sensitization strategy based on the teachings of KH Ahmad Dahlan that consists of four phases (sensitivity to security, sensitivity to the surrounding environment, sensitivity to discrimination, and sensitivity to victims of violence). This study recommends further research to identify the effectiveness of the social sensitization strategy containing the teachings of KH Ahmad Dahlan to achieve peace among students at school.

Inquiry skills are one of the skills that students need to master in learning biological concepts. Inquiry skills are influenced by many factors, one of which is the lesson plan. This study aims to examine the effect of inquiry lab and STEM models on inquiry skills progression. The research design used was a quasi-experiment non-randomized control group, pretest-posttest design, with three treatments, namely discovery learning lesson plan as control (C), inquiry lab lesson plan (E1) and STEM lesson plan (E2) as treatment. The three classes were randomly selected from six classes XI of Science. All students in the selected class became the research sample (N = 98), with details. The control class consisted of 33 students, E1 32 students, and E2 33 students. The material taught in all classes is the human respiratory system. Data in inquiry skills progression is measured before and after treatment. The instrument takes the form of an essay test. Data analysis using ANCOVA (p = 0.05%). The results showed that the inquiry lab and STEM models had a significant effect, and the inquiry lab model had the best effect.

Estimation of temporospatial clinical features of gait (CFs), such as step count and length, step duration, step frequency, gait speed, and distance traveled, is an important component of community-based mobility evaluation using wearable accelerometers. However, accurate unsupervised computerized measurement of CFs of individuals with Duchenne muscular dystrophy (DMD) who have progressive loss of ambulatory mobility is difficult due to differences in patterns and magnitudes of acceleration across their range of attainable gait velocities. This paper proposes a novel calibration method. It aims to detect steps, estimate stride lengths, and determine travel distance. The approach involves a combination of clinical observation, machine-learning-based step detection, and regression-based stride length prediction. The method demonstrates high accuracy in children with DMD and typically developing controls (TDs) regardless of the participants level of ability. Fifteen children with DMD and fifteen TDs underwent supervised clinical testing across a range of gait speeds using 10 m or 25 m run/walk (10 MRW, 25 MRW), 100 m run/walk (100 MRW), 6-min walk (6 MWT), and free-walk (FW) evaluations while wearing a mobile-phone-based accelerometer at the waist near the bodys center of mass. Following calibration by a trained clinical evaluator, CFs were extracted from the accelerometer data using a multi-step machine-learning-based process and the results were compared to ground-truth observation data. Model predictions vs. observed values for step counts, distance traveled, and step length showed a strong correlation (Pearsons r = -0.9929 to 0.9986, p < 0.0001). The estimates demonstrated a mean (SD) percentage error of 1.49% (7.04%) for step counts, 1.18% (9.91%) for distance traveled, and 0.37% (7.52%) for step length compared to ground-truth observations for the combined 6 MWT, 100 MRW, and FW tasks. Our study findings indicate that a single waist-worn accelerometer calibrated to an individuals stride characteristics using our methods accurately measures CFs and estimates travel distances across a common range of gait speeds in both DMD and TD peers.

Differences in gait patterns of children with Duchenne muscular dystrophy (DMD) and typically developing (TD) peers are visible to the eye, but quantifications of those differences outside of the gait laboratory have been elusive. In this work, we measured vertical, mediolateral, and anteroposterior acceleration using a waist-worn iPhone accelerometer during ambulation across a typical range of velocities. Fifteen TD and fifteen DMD children from 3 to 16 years of age underwent eight walking/running activities, including five 25 m walk/run speed-calibration tests at a slow walk to running speeds (SC-L1 to SC-L5), a 6-min walk test (6MWT), a 100 m fast walk/jog/run (100MRW), and a free walk (FW). For clinical anchoring purposes, participants completed a Northstar Ambulatory Assessment (NSAA). We extracted temporospatial gait clinical features (CFs) and applied multiple machine learning (ML) approaches to differentiate between DMD and TD children using extracted temporospatial gait CFs and raw data. Extracted temporospatial gait CFs showed reduced step length and a greater mediolateral component of total power (TP) consistent with shorter strides and Trendelenberg-like gait commonly observed in DMD. ML approaches using temporospatial gait CFs and raw data varied in effectiveness at differentiating between DMD and TD controls at different speeds, with an accuracy of up to 100%. We demonstrate that by using ML with accelerometer data from a consumer-grade smartphone, we can capture DMD-associated gait characteristics in toddlers to teens.

In the title molecule, C20H18ClN3O2, the 2-chlorophenyl group is disordered to a small extent [occupancies 0.875 (2)/0.125 (2)]. The phenylacetamide moiety is nearly planar due to a weak, intramolecular C—H...O hydrogen bond. In the crystal, N—H...O hydrogen bonds and π-stacking interactions between pyridazine and phenyl rings form helical chains of molecules in the b-axis direction, which are linked by C—H...O hydrogen bonds and C—H...π(ring) interactions. A Hirshfeld surface analysis was performed, which showed that H...H, C...H/H...C and O...H/H...O interactions to dominate the intermolecular contacts in the crystal.

Fiber optic research continues to develop due to the need for fast information technology. The input signal in an optical fiber is in the form of a soliton wave that propagates in the fiber with a balanced index of refraction, dispersion, and diffraction. Fiber optics may lose some of the signal over time if they solely use a nonlinear refractive index. This study aims to examine into the dynamics and decoherence of multi-peak solitons caused by electromagnetic signal attenuation and potential trap in the propagation via optical fibers. The methods used start with the stationary solution of the nonlinear Schrödinger Cubic Quintic equation, the Newton-Raphson method, and the fourth-order Runge-Kutta. In stationary solutions, the p (state energy) and ρ (Lèvy index) values affect the number, pulse width, and height of soliton peaks. Increased p and ρ values lead to increased instability, causing the data transmitted into the optical fiber to collapse and become unreadable by the receiver. In the excited state (p > 0), the decoherence phenomenon occurs and causes wave instability and destruction. In term of energy intensity, a stable form of transmission in the ground state has a pattern of continuously weakening, decreasing, and smoothing, while in the excited state there is a spike in the intensity of the electromagnetic wave. Based on this study, multi-peak solitons can only be applied for propagation distances, which tend to be short due to their dynamics and decoherence.

Background Children with epilepsy are at high risk of cognitive impairment that can affect quality of life. Intelligence quotient (IQ) measurement using the Wechsler Intelligence Scale for Children (WISC) is the gold standard test of cognitive function, but it is time-consuming and costly. The School Years Screening Test for Evaluation of Mental Status-Revised (SYSTEMS-R) is a potential cognitive function screening tool that can be used in children with epilepsy. Objective To assess the performance of SYSTEMS-R as a cognitive function screening tool in children aged 6-15 years with epilepsy. Methods This cross-sectional diagnostic test study was conducted in children aged 6-15 years with epilepsy. All subjects were assessed using both SYSTEMS-R and WISC 4th edition. The sensitivity, specificity, positive and negative predictive value, likelihood ratios of the positive and negative tests, and accuracy of SYSTEMS-R was calculated, with WISC as the gold standard test. Results Based on the SYSTEMS-R, the prevalence of cognitive impairment in children aged 6-15 years with epilepsy in our population was 86.4%. With WISC as the gold SYSTEMS-R had 84% sensitivity, 91% specificity, 98% positive predictive value, and 47% negative predictive value. The likelihood ratio of a positive SYSTEMS-R test was 10.11 and the likelihood ratio of a negative test was 0.17. The overall accuracy of SYSTEMS-R to detect cognitive impairment was 85%. Conclusion SYSTEMS-R has good sensitivity and specificity to assess cognitive function in children 6-15 years with epilepsy. It can be considered for widespread use in the early detection of cognitive impairment in pediatric epilepsy patients aged 6-15 years.

Abstract Objective Medication-related osteonecrosis of the jaw bones (MRONJ) is a well-known complication of antiresorptive and antiangiogenic drugs. Since the first report, more occurrences of MRONJ have been described worldwide. Dental extraction has been described by many studies as one of the risk factors for MRONJ. Comprehensive dental care (CDC) is a preventive dental method provided to patients prior to drug commencement. This study aims to determine the association between CDC and MRONJ. Patients and methods. A retrospective analysis was performed on 75 medical records of patients on antiresorptive and/or antiangiogenic drugs between February 2018 and May 2021. Demographics and clinical and radiographic data were collected. Univariate and multivariate analyses were performed to determine the factors associated with MRONJ. Results Of the 75 patients who met the inclusion criteria, 11 (14.7%) developed MRONJ. Three out of 11 patients (27.2%) developed MRONJ spontaneously, while eight patients (72.8%) developed it after trauma from dentures or dental extractions. Following a binary logistic regression analysis, the lack of CDC was identified as a significant predictor of MRONJ. Patients who did not receive CDC had an odds ratio of 8.64 (95% confidence interval (CI): 1.27–58.62, p = 0.03). However, dental extraction did not show a statistically significant association with MRONJ in both the univariate and multivariate analyses. Conclusion CDC before treatment with antiresorptive and antiangiogenic drugs is a potentially effective preventive method for reducing MRONJ. Dental extraction was not a significant factor in relation to MRONJ.

This paper focuses on the modelling of a multimode double-pendulum overhead crane (MDPOC) system which generates double-pendulum phenomenon. The MDPOC is far more complex than those of single-pendulum overhead cranes due to the additional degree of freedom, greater nonlinearities, and stronger internal couplings especially involving two or more oscillation frequencies with multimode dynamic effects. More interestingly, two scenarios under fixed and varying cable lengths (payload hoisting) are considered which are closer to the real practical crane. The dynamic crane models are derived using Lagrange’s method. Simulations using the Matlab/Simulink block diagram, as well as experiments on a laboratory overhead crane are used to verify and validate the accuracy of MDPOC mathematical modelling. The simulation and experimental results demonstrate the superiority and similar pattern of the trolley position, hook oscillation and payload oscillation under fixed and varying cable lengths that verified the mathematical modelling of MDPOC. It is beneficial for crane operators to understand the dynamic model of MDPOC and useful for future analysis of controller implementation with confidence by researchers.

This research aimed to detect students' ability to write narrative text using local legendary picture series and further explore their perceptions of using picture series in writing narratives. A descriptive quantitative research design was employed, and 30 students (10 males and 20 females) participated as respondents in the present study. Furthermore, the students were asked to write a narrative text based on a series of pictures from the local legend of Danau Toba. The findings indicated that picture series significantly enhanced students' narrative writing skills. The average scores revealed that the organization, vocabulary, and grammar were 3.19, 3.43, and 2.92 respectively, categorized into the "Good" level. Meanwhile, the average score for mechanical ability was 2.46, categorized as "Enough". Furthermore, the majority of students viewed positively to the use of picture series, with 46.67% strongly agreeing and 46.67% agreeing that picture series enhanced their ability to absorb and retain information. Thus, the picture series used are effective media for learning narrative writing skills. This study may serve pedagogical implication to the teaching of writing skills. Therefore, the researchers recommend that teachers integrate picture series in their teaching strategies and next researchers could explore the use of picture series in other text types and across various English language skills to provide broader insights and potentially more robust pedagogical strategies.

Abstract Rapid economic growth in Indonesia and Malaysia has widened the gap in emergency care supply and demand, intensifying challenges. Our study, from August to November 2022, assesses current diverse challenges in both countries' emergency care systems from frontline staff perspectives. The online survey involved emergency department (ED) personnel from 11 hospitals in Indonesia and Malaysia, drawing from an existing network. The survey collected data on respondents’ characteristics, factors affecting prehospital and ED care quality, missing clinical information, and factors influencing patients’ ED stay duration. With 83 respondents from Indonesia and 109 from Malaysia, the study identified common challenges. In both countries, inadequate clinical information from ambulances posed a primary challenge in prehospital care quality, while crowdedness during night shifts affected ED care quality. Frequent gaps in essential clinical information, such as family and medication history, were observed. Prolonged ED stays were associated with diagnostic studies and their turnaround time. This study offers insights into shared challenges in Indonesia and Malaysia's emergency care systems. Our findings stress recognizing common and country-specific challenges for enhanced emergency care quality in Southeast Asia, supporting tailored interventions.

This study aims to isolate and characterise the Pink Pigmented Facultative Methylotrophs (PPFM) bacteria from the leaves of common Malaysian table salad (ulam). The colonies of PPFM bacteria were obtained using selectively modified Pseudomonas agar based on the appearance of the pink pigment colony. The three selected isolates labelled OJ4, OJ154 [Oenanthe javanica (Blume) DC.] and ML8 [from Melicope lunu-ankenda (Gaertn.) T. G. Hartley] were chosen for characterisation. The result showed the PPFM bacteria colonies (log CFU/g) at the leaf surface of C. caudatus are 4.4 ± 0.1, significantly higher than O. javanica, 3.8 ± 0.2, and M. lunu-ankenda, 3.2 ± 0.1. The selected isolates belong to the Gram-negative group, motile with rod shape with size [length (l) × width (w)] in µm unit 4.3 ± 1.1 × 1.6 ± 0.6, 5.4 ± 0.2 × 1.2 ± 0.1, and 3.5 ± 0.7 × 1.0 ± 0.0, respectively. They show positive urease, catalase, and oxidase activities, while none of them can degrade starch, gelatine, or cellulose, as well as glucose fermentation (MR test) and metabolism actions (VP test), producing indole and hydrogen sulphide gaseous. Only isolate OJ154 demonstrates positive casein hydrolysis and nitrate reduction activities, while only isolate ML8 can utilise citrate but not in lipid degradation. Their sequence analysis of the 16S rRNA indicated that OJ4 and ML8 are Methylobacterium radiotolerans with a similarity of 99%, whereas, OJ154 is Methylorubrum salsuginis with a similarity of 99%. To conclude, PPFM bacteria from the leaves of C. caudatus, O. javanica, and M. lunu-ankenda have been isolated and characterised in particular.

Cryptocaryon irritans, known as cryptocaryonosis disease infection in fish, is a significant problem for aquarists because they not only cause the disease but also lead to high mortality in the aquarium population. This case report aims to identify Cryptocaryon irritans infection in four Indian Ocean oriental sweetlips at the Jakarta Aquarium and Safari. Before they died, a total of four fish showed signs of weakness, scratching, excessive mucus, and pale gills. The diagnosis was confirmed through clinical assessment, physical examination, and microscopic analysis of skin scrape and gill clip samples, which revealed the presence of numerous trophonts (the young immature stages) of C. irritans. These findings underscore the importance of vigilant monitoring and prompt intervention to mitigate the impact of C. irritans, especially on marine aquarium fish populations.

Objective: To study the effect of a nanoparticulate brain-derived neurotrophic factor with surfactant (BDNF) on the modeled depression not associated with stress in mice Methods: Thirty-six C57BL/6 mice weighing 20-25 g were included in the study with reserpine-induced depression. The animals were divided into three groups: Group 1 – negative control, involving animals treated with normal saline, Group 2 – positive control involving animals treated with a traditional antidepressant fluoxetine, and Group 3 – experimental, treated with nanoparticulate BDNF with a surfactant. Open field, sucrose preference, and forced swimming tests were applied in the study, and the ELISA method was used to determine the corticosterone level in the serum. Digital morphometry of the adrenal cortex and thymus was done. SPSS 27.0.1 software was used for statistics, with a p

The dihydroimidazole ring in the title molecule, C20H20N2O3S, is slightly distorted and the lone pair on the tri-coordinate nitrogen atom is involved in intra-ring π bonding. The methylsulfanyl substituent lies nearly in the plane of the five-membered ring while the ester substituent is rotated well out of that plane. In the crystal, C—H...O hydrogen bonds form inversion dimers, which are connected along the a- and c-axis directions by additional C—H...O hydrogen bonds, forming layers parallel to the ac plane. The major contributors to the Hirshfeld surface are C...H/H...C, O...H/H...O and S...H/H...S contacts at 20.5%, 14.7% and 4.9%, respectively.

In the title molecule, C25H29N5O, the dihydroquinoxaline unit is not quite planar (r.m.s. deviation = 0.030 Å) as there is a dihedral angle of 2.69 (3)° between the mean planes of the constituent rings and the molecule adopts a hairpin conformation. In the crystal, the polar portions of the molecules are associated through C—H...O and C—H...N hydrogen bonds and C—H...π(ring) and C=O...π(ring) interactions, forming thick layers parallel to the bc plane and with the n-octyl groups on the outside surfaces.

This study introduces a lead-free alternative for enhanced radiation protection. While lead aprons effectively attenuate ionizing radiation, concerns regarding flexibility, weight, and environmental hazards persist. In response, the present research is focused on producing an innovative sheet shielding comprised of carefully selected dense metal oxide microparticles (DMOs-MPs) and liquid silicone rubber (LSR). To evaluate the efficacy of the LSR samples, the current study uses rigorous testing procedures, such as microstructure characterization using EDX and FESEM. Furthermore, the study investigated key attenuation parameters within the LSR samples. Radiation protection was greatly and effectively supplied using DMOs-MPs filler (Bi-1 to Bi-7) in LSR samples; this protection reached 99.9% in the X-ray energy range. Due to the unique characteristics of the Bi-7, the results demonstrated that the samples’ shielding efficiency improved with the addition of high atomic number and high-density fillers. It had the greatest attenuation coefficient and density. At 60 keV, Bi-7’s density was 2.980 gcm−3, and its LAC and MAC were 19.2621 cm−1 and 6.4638 cm2/g, respectively. It also had the lowest half-value layer values in the energy range of 60–120 keV. The LSR samples showed effective radiation absorption for different energy levels, indicating that LSR can enhance the flexibility and comfort of the apron while providing adequate radiation protection. The incorporation of the DMOs-MPs with LSR represents an effective contribution and a noteworthy stride to enhance the safety and well-being of medical professionals routinely exposed to ionizing radiation.

Learning Science, Technology, Engineering, and Mathematics (STEM) subjects in an online medium can be difficult and tedious. Lengthy facts with technical terms, complex images, and explanations are among the reasons that make STEM subjects less desirable among the current generation and degrade the students' learning experience. Students can be assisted with learning applications that are not only mobile but also integrated with features that are enjoyable to trigger students' interest in STEM. Game elements and augmented reality (AR) are two technologies that are capable of improving students' learning experience. However, there are limited guidelines for designing mobile learning applications that are based on game elements and AR. Moreover, the existing guidelines mostly focus on usability but not the overall learning experience. Therefore, this paper aims to design a model of a mobile learning application that integrates AR and game elements to improve the student learning experience. The model consists of three elements; content, pedagogy/technology, and interaction that was initially verified by the subject matter experts. A mobile application prototype called m-BioP was developed based on the model and tested heuristically. A complete version of m-BioP was evaluated in an experimental study with 30 respondents using the User Experience Questionnaire (UEQ). Respondents were biology students aged between 16 and 23 years that were recruited by purposive sampling. The results were positive on almost all features of m-BioP with values higher than 0.8 on the pragmatic and hedonic scale, thus approving the developed model. Based on the evaluation, the only aspect that requires improvement is the design of the videos. The model can be used by academicians and learning content creators as a guideline to design and develop mobile learning applications that are able to provide STEM students with a better learning experience.
