Integrating pre-vocational education to promote identity development in adolescents: An exploration of Erikson's theory

2026-09-03T06:35:28+00:00

This present study is about the relationship between Erikson’s Identity vs. Role Confusion stage and pre-vocational education at the middle school level, specifically evaluating how pre-vocational programmes can support identity development among adolescents. The Identity vs. Role Confusion stage, which lasts from 12 to 18 years of age, is marked by an examination of one's own identity and role. According to research, pre-vocational education which instils practical skills and career-oriented learning is essential for promoting the development of identities because it gives adolescents the chance to experiment with different roles, interests, and skills. According to the literature, students who participate in skill-based learning gain a better understanding of who they are since these experiences give them important information about their interests, strengths, and potential career paths. Psychological development focusing on identity development shows that pre-vocational programmes that integrate Indigenous crafts like crafting and weaving can strengthen cultural pride and identity. Among the psychological theories that affect development in the adolescence period, Erikson’s framework is particularly applicable to guiding pre-vocational education, as it addresses both the social importance of occupational exploration and the psychological need for self-definition. This review emphasises how pre-vocational education can meet the psychological needs of middle-stage students by including culturally relevant and practical skills. Such integration provides a comprehensive strategy that promotes cultural connectedness and self-assurance, which reduces uncertainty about roles and improves the development of adolescent identities. Overall, pre-vocational education proves to be an essential means of fostering identity development throughout this important stage of adolescence.

Taxonomic identification and documentation of polyherbal antidiabetic herbal formulations used by traditional herbalists in North Rift region, Kenya

2026-09-10T13:14:15+00:00

Traditional herbalists in Kenya's North Rift region extensively use polyherbal formulations to manage diabetes mellitus, yet scientific documentation and taxonomic authentication of the constituent medicinal plant species remain limited. This study aimed to identify and document polyherbal antidiabetic formulations used by traditional herbalists in the North Rift region of Kenya. A cross-sectional ethnobotanical survey involving purposively selected experienced herbalists was conducted using semi-structured interviews, guided field walks, direct observation, and plant specimen collection. Collected specimens were authenticated through standard taxonomic procedures using morphological characters, herbarium reference collections, and international botanical databases, with voucher specimens deposited at the University of Eldoret Herbarium. Five commonly used polyherbal antidiabetic formulations comprising twenty-two medicinal plant species belonging to fourteen plant families were documented from Uasin Gishu, West Pokot, Timboroa, and Marakwet. Frequently recorded species included Conyza schimperi, Conyza hypoleuca, Leonotis nepetifolia, and Croton macrostachyus. Leaves, bark, roots, shoots, and tubers constituted the principal plant parts utilized in the formulations. Botanical authentication confirmed the identity of all documented species, reducing the risk of misidentification and adulteration. The study provides a scientifically validated inventory of indigenous antidiabetic medicinal plants that forms a valuable foundation for future phytochemical, pharmacological, quality assurance, conservation, and drug development research in Kenya.

Availability of digital simulation resources for teaching abstract biology concepts in public secondary schools in Baringo North Sub-County, Kenya

2026-09-11T12:11:30+00:00

Despite the growing integration of digital technologies in education, inadequate access to appropriate digital resources may constrain the teaching of abstract Biology concepts involving processes that are difficult to observe directly. This study investigated the availability of digital simulation resources for teaching abstract Biology concepts in public secondary schools. The study adopted a descriptive survey research design. The target population comprised 50 teachers of Biology and 5,894 Form Three learners in public secondary schools in Baringo North Sub-County, Kenya. A sample of 45 Biology teachers and 350 Form Three learners participated in the study. Data were collected using a teachers’ questionnaire and an observation checklist. Quantitative data were analyzed using SPSS Version 27. Descriptive statistics, including frequencies, percentages, means and standard deviations, were used to summarize the data, while a one-sample chi-square goodness-of-fit test determined whether observed availability differed significantly from the expected 50.0% distribution. The findings indicated that digital simulation resources were moderately available, with 60.0% of the observed resource indicators available. This proportion was significantly higher than the expected 50.0%, χ²(1) = 36.00, p < .001. However, important gaps persisted in Biology-specific simulation software, curriculum-aligned digital content, adequate computers, learner access, backup power, ICT technical support and classroom utilization of digital simulations. The study concluded that effective integration requires more than basic ICT infrastructure and recommends strengthening access to functional devices, curriculum-aligned simulations, technical support, reliable power and continuous teacher training to promote equitable and sustained use of digital simulations in teaching abstract Biology concepts.

Islamic educational values in Ustadz Das’ad Latif’s preaching on social media: A study of content analysis and the perceptions of generation Z in Salakan city

2026-09-18T13:03:14+00:00

This study examines Islamic educational values within Ustadz Das’ad Latif’s da’wah (Islamic preaching) on social media, by addressing the following questions; what forms do Islamic educational values take in Ustadz Das’ad Latif’s da’wah content and how does Generation Z perceive the Islamic educational values found in Ustadz Das’ad Latif’s da’wah content on social media? This study employed a qualitative research method, utilizing content analysis, in-depth interviews, and document analysis. The data were analyzed through data reduction, data presentation, data verification, and conclusion drawing. The results of the study indicate that ustadz Das’ad Latif’s preaching embodies Islamic educational values predominantly concerning aqidah (faith), ibadah (worship), and akhlaq (morality), as well as values related to character education and social concern. These values are conveyed through calls to believe in Allah SWT, perform acts of worship, honor one’s parents, cultivate noble character, and care for others, the environment, and society at large. His communicative and humorous delivery style, incorporating analogies, personal experiences, and real-life examples, makes the message easier to understand and accept. Ustadz Das’ad Latif’s preaching method implements the three approaches outlined in Islamic preaching, such as wisdom, good counsel, and reasoning, in the best manner. These methods are applied in an integrated fashion through humor, advice, motivation, rhetorical questions, comparisons, and arguments relating to everyday life issues. Generation Z holds a positive yet critical perception of ustadz Das’ad Latif’s preaching content on YouTube. The content is viewed as engaging, accessible, relevant, and beneficial for providing knowledge and motivation, as well as encouraging self-improvement and positive social engagement. As such, YouTube holds potential as a medium for dakwah targeting Generation Z, although factors such as information credibility, the appropriateness of humor, video duration, and source verification remain important considerations. Thus, the success of digital dakwah depends not only on the substance of the message but also on the ability to package it in a way that is relevant, communicative, and engaging, while remaining consistent with Islamic values.

The role of character education in shaping the digital ethics of students at State Islamic Junior High School

2026-09-22T07:49:27+00:00

This study aims to investigate the role of character education in shaping students' digital ethics at State Islamic Junior High School. This study uses qualitative methods. In qualitative research, theory serves only as a guide for data gathering and analysis. The data were collected through direct observation, in-depth interviews, and written document analysis at the research site. The research was conducted in an Islamic junior high school in Palu city, Indonesia. The researcher chose the school because the school is a reputable government school that implements policies on digital ethics, which are relevant to Islamic education. The results of this study show that character education plays a fundamental role in shaping students' digital ethics. This role is not fulfilled through a single program or specific activity, but rather through a character education ecosystem that integrates the school policies, curriculum, instruction, school culture, teacher role-modeling, guidance and counseling services, and student participation. All these components function as interconnected mechanisms in the process of internalizing character values among students. At the institutional level, character education is reinforced through policies and programs that position character building as an integral part of educational goals. At the curriculum and instructional levels, character values are integrated into the learning process particularly within Islamic Religious Education by linking lessons on ethics and moral conduct to students' real-life issues, including their use of digital media and technology.

The influence of digital parenting on child development with the family environment as a moderating variable at Islamic elementary schools

2026-10-01T08:02:53+00:00

This study addresses the influence of digital parenting on children's religious and moral, cognitive, social, and emotional development at Islamic elementary schools in Palu City, as well as the role of the family environment in moderating this influence. The study aims to analyze the direct impact of digital parenting on these four aspects of child development and to examine the moderating role of the family environment. An associative-explanatory quantitative approach was employed. The study population consisted of 1,446 parents of students from two Islamic schools. A sample of 313 parents was determined using Slovin's formula and proportional random sampling. Data collection utilized questionnaires as the primary instrument, supplemented by observation, interviews, and documentation. Data analysis used Structural Equation Modeling–Partial Least Squares (SEM-PLS) in SmartPLS, including evaluation of the outer model, inner model, and bootstrapping, as well as testing direct and moderating effects. The results indicate that the measurement model met validity and reliability criteria, with outer loadings of 0.803–0.896, AVE values of 0.686–0.756, HTMT values below 0.85, and Cronbach's Alpha and Composite Reliability values above 0.70. For the inner model, VIF values ranged from 1.001 to 1.002, Adjusted R² from 0.512 to 0.553, and Q² from 0.349 to 0.389, indicating moderate explanatory power and good predictive relevance. Digital parenting had a positive and significant influence on religious and moral (β=0.668; p<0.001), cognitive (β=0.613; p<0.001), social (β=0.641; p<0.001), and emotional (β=0.597; p<0.001) development. The family environment does not have a direct, significant effect on the four aspects of child development; however, its interaction with digital parenting has a positive and significant impact on religious and moral values (β=0.305), cognitive (β=0.347), social (β=0.299), and emotional (β=0.371) aspects all with p<0.001. Thus, the family environment reinforces the influence of digital parenting, establishing a pattern of pure moderation. The study's implications underscore the importance of communication, guidance, supervision, and a conducive family environment in digital parenting. Parents need to enhance their digital parenting literacy, and schools should strengthen collaboration and digital literacy with families. At the same time, the government can use these findings as a basis for developing family-based digital parenting education programs.

Estimation and comparison of organic acids in natural fruits

2026-09-27T14:54:10+00:00

Organic acids represent a fundamental category of natural chemical compounds that define the biochemical identity of fruits, acting as the primary "flavor architects" and metabolic intermediates within the plant's life cycle. Fruits and plant-based products have been utilized for both nutritional and medicinal purposes since the earliest human civilizations, serving as a primary defense against various ailments. In the modern era, there is an emerging global trend toward increased fruit consumption as a strategic response to the rise of non-communicable diseases (NCDs) such as diabetes, cardiovascular issues, and cancer. These diseases are often linked to oxidative stress within the body, where an imbalance between free radicals and antioxidants leads to cellular damage. Fruits supply essential nutrients, particularly organic acids and polyphenols, which improve immune function and serve as natural scavengers to quench these harmful reactive oxygen species. Consequently, the chemical quantification of these acids is not merely a laboratory exercise but a vital step in understanding how dietary choices can mitigate long-term health risks in both developed and developing countries. Beyond their health benefits, the chemical complexity of fruits is centered largely on their Total Vitamin C Content (TVC), which researchers define as the sum of ascorbic acid (AA) and its oxidized form, dehydroascorbic acid (DHA). DHA can be reversibly reduced back into ascorbate in the human body, making both forms equally important for nutrition.

The scientific method used in this research paper is acid -base titration, a volumetric analysis technique where a solution of known concentration (the titrant) is added to a solution of unknown concentration. In the context of fruit acids, the analyte is the diluted fruit juice (containing organic acids like citric, malic, or ascorbic acid), and the titrant is a standardized solution of sodium hydroxide (NaOH). The effectiveness of this method is primarily rooted in its stoichiometric reliability, where the reaction between a strong base like sodium hydroxide and organic acids occurs in fixed, predictable ratios. This allows for a precise, quantitative determination of acid content, providing a numerical value that is essential for comparing the natural tartness of different fruits or accurately monitoring the stages of fruit ripeness. The overarching aim of this research is to quantitatively analyze and compare the total acid content present in a selection of different sour fruits commonly available in local markets, namely lemon, tomato, tamarind, and sweet lime. This study is designed to bridge the gap between the perceived tartness of these fruits and their actual chemical concentration through the application of standard analytical chemistry techniques. By determining the "titratable acidity" of each fruit, the experiment seeks to establish a clear chemical profile that categorizes these fruits based on their molarity and the strength of the organic acids they contain.

How a sub-lethal effect of natural mosquitocides contribute in control of mosquito borne diseases in view of ecofriendly bioinsecticides: A review article

2026-10-13T11:59:50+00:00

Mosquitoes are more threaten human and other veterinary animals, than any other arthropod or even another macrocarnivorous animals, which are vectors of pathogenic agents of many serious diseases as malaria, lymphatic filaria, and arboviruses such as; yellow fever, Nile fever, dengue. zika, Japanese encephalitis. and, chikungunya, Zika, and dengue. Moreover, host annoyances within taking up blood meal by female piercing mouth parts. In spite of forests are mosquito niche, but now are consider as urbane insect inhabitate brackish and polluted water and modulated their habit into anthropophilic behavior. To raise awareness about the dangers of mosquito-borne diseases, now public health organizations are annually celebrated by World Mosquito Day in 20^th august since 1937, the day commemorates the discovery made by Sir Ronald Ross in 1897, who established that female Anopheles mosquitoes transmit malaria. Mosquito control programs were mainly emphasized on immature stages, by application with synthetic insecticides. But, after appearances of ecological problems and insecticide-resistance, mosquito control tends to sublethal doses to minimize environmental effect and preserve on biological diversity.

The sublethal effect of bioinsecticides as plant secondary metabolites resources (as juvenoids and phytoecdysosteroide) and non-consumption by the mosquito predators kairomones, which are interfere with the mosquito natural hormones and other metabolic activities. This effectiveness less than mortality, will not allow the generation fitness. Today, literature body about mosquito program control mainly focusing on sublethal activity of the bioinsecticides, therefore, in this review, we shall evaluate the effectivity of biological insecticides as plant extracts and predators with sublethal doses and non-consumptive effectiveness of mosquito predators.

This study examines the principal’s supervision model in enhancing the performance of Islamic Education teachers in a state senior high school in Palu. This research used a qualitative case study approach. The primary informants were school principals, Islamic education teachers, and students. Data were collected through semi-structured interviews, participatory observations, analysis of written materials, and teachers' teaching experience. All data were analyzed thematically through stages of data reduction, data display, and conclusion drawing/verification. The validity of the findings was ensured through triangulation of sources and techniques, as well as participant validation. The results show that multiple intelligences-based Islamic religious education at State Senior High School in Palu begins with identifying students' characteristics, needs, abilities, interests, and potential through observation, interaction, activities, and student responses. These insights serve as the basis for determining learning objectives, content, strategies, methods, media, activities, and assessments. The planning is student-oriented, flexible, and contextual. However, the mapping of the eight types of intelligence has not been conducted using formal instruments nor explicitly documented in the instructional materials. In implementation, teachers deliver multiple intelligences-based instruction through introductory, core, and concluding phases that provide diverse learning experiences. Teachers use discussions, question-and-answer sessions, group work, presentations, assignments, practical exercises, instructional media, and reflection to help students develop linguistic, interpersonal, kinesthetic, visual-spatial, intrapersonal, and logical-mathematical abilities.
