Abstract

Education is a right to every child, but Sokoto is suffering from many issues ravaging education, therewith, a major issue is the Almajiri school. Because the Almajiri schools are abandoned there is every tendency that their drinking water is contaminated considering the rising pattern of pollution across the globe. The aim of the study was to carry out an analysis of heavy metal content in well water and propel some predictive insights for students well-being in Almajiri schools in Sokoto, Nigeria.  Samples of well water were collected from Almajiri schools in Sokoto state and metals were analyzed using atomic abortion spectroscopy. 60.10 ± 5.1 to 600.1± 0.01, 100.1 ± 0.5 to 600.0 ± 0.02, are the ranges of calcium, and magnesium macroelements determined.  The ranges for essential heavy metals zinc, and iron are as follows; 2.34 ± 0.05 to 5.00 ± 0.02 (zinc), and 0.54± 0.05 to 10.43 ± 0.5 (iron) respectively. The ranges of Pb, Hg, and Cd assessed are as follows: lead (0.0 to 1.06 ± 0.005), mercury (0.10 ± 0.002 to 2.501 ± 0.01), and cadmium (0.00122 ±0.0004 to 0.0761 ± 0.0001). The HI for the heavy metals determined are in the order of schools B>D>A>C. The metals determined are either excess or little (with respect to essential heavy metals) in many cases.  In one school, the HI is far above 1 and therefore risk the population with effects. Thus, can elicit harm to the consumers. They can affect the academic, cognitive capacity of the Alamjiri children. There is need to take proper measures to save the health and future development of the Almajiri child against heavy metals poisoning possibility.

Abstract

This study investigated the efficacy of Problem-Based Learning (PBL) in enhancing students' problem-solving abilities in physics education, addressing the lack of effective methodologies in nurturing this crucial skill. Utilizing a quasi-experimental design, 58 secondary school students from Nigeria were divided into an experimental group, which received PBL instruction, and a control group, which received traditional teaching methods. Over three months, both groups were assessed using an essay test format before and after the intervention, focusing on problem-solving abilities related to force and motion concepts. Descriptive and inferential statistical analyses were employed to evaluate the pretest, posttest, and n-gain scores, revealing significant improvements in problem-solving abilities within the experimental group compared to the control group. Specifically, students exposed to the PBL model exhibited higher average scores and greater improvement in problem-solving skills across various indicators, including understanding the problem, developing a plan, implementing the plan, and reflecting on solutions. The findings underscored the effectiveness of the PBL model in fostering active engagement, collaborative learning, and structured problem-solving processes, aligning with contemporary educational approaches that prioritize practical skill development and critical thinking. This study contributed to the growing body of literature supporting the efficacy of PBL in enhancing problem-solving abilities, highlighting its potential to cultivate a dynamic learning environment conducive to the development of essential skills in physics education.

Abstract

It is widely stressed that girl-child education is good; and girls could only learn properly if they are fed well. Levels of micronutrients such as antioxidants vitamins A and C could lead to poor brain or nervous system functions. The objective of this work was to evaluate the relationship between Micronutrients deficiencies (poor levels of antioxidants Vitamin A and Vitamin C) and academic performance of selected young girls in Sokoto, Nigeria. This work determined blood levels of vitamin A and C in 250 young girls in Sokoto using standard methods and materials of analytical grade. A semi experimental study involving 40 selected study participants was done. An exploration of academic performance of subjects that are with enough vitamin C and A and their counterparts was done using assessment. This study shows that, the girls with normal levels of antioxidants vitamins A and C scored a mean mark (55.0+ 13.015) more than those with poor levels (35.63+12.63) (p<0.05). This signifies that nutritional concerted interventions are needed. Nutritional education, soil fertilization, bio fortification, and relations could be used for improving public diet in the state.

Abstract

Abstract: Problem-solving skills are among the most important competencies of students, especially in the area of science education in the 21st century. Problem-solving skills enhance critical, logical, and creative thinking skills, which are necessary to solve complex real-life problems. This study is intended to identify and analyze research trends with regard to problem-solving skills in science learning from 2014 to 2023. A qualitative bibliometric approach has been used, and the data was collected using Publish or Perish and Dimensions.ai. In total, 200 documents indexed by Google Scholar were analyzed. Research trends, key keywords, and publication patterns were mapped and visualized using the VOSviewer software. The findings indicated that research on problem-solving skills gained consistent interest over the last decade, with the highest number of publications in 2023. Journals were the most common type of publication, followed by proceedings, chapters, and books. Among all publication venues, the Journal of Physics: Conference Series turned out to be the most important, publishing 784 articles and receiving 2567 citations. The most frequent keywords accompanying research in problem-solving are "critical thinking," "science learning," "motivation," and "teacher," which point to the interdisciplinary nature of the topic. Bibliometric visualization shows the emergence of new research clusters: student skills development, teaching strategies, and assessment methods. The conclusion from this study is that, while the research on problem-solving skills has grown steadily in science education, the implementation of practical teaching strategies in a classroom to enhance these skills remains fragmented. The future direction for research should encompass experimental studies through the integration of problem-based learning approaches that are important in the development of critical and creative thinking among students. Such findings have an important basis for educators, policymakers, and researchers to devise evidence-based practices that enhance the outcomes of science education.     Keywords: problem-solving skills, 21st-century competencies, science learning, bibliometric analysis, critical thinking.

Abstract

Abstract: This study explores trends in the design and implementation of research and development (RD) models tailored for science education rooted in local wisdom within the Nusa Tenggara region (NTB and NTT), Indonesia. Utilizing a Systematic Literature Review (SLR) methodology, the research synthesizes findings from 20 pertinent articles published between 2017 and 2023, adhering to specific inclusion and exclusion criteria. Selected studies are indexed in SINTA (levels 1–6) and focus on ethnoscience, local wisdom, and RD models, while studies outside primary and secondary school science education or predating 2017 were excluded. The review identifies ADDIE (Analyze, Design, Develop, Implement, Evaluate) and 4D (Define, Design, Develop, Disseminate) as the most frequently employed development models, each representing 40% of the analyzed studies. Their popularity stems from their structured processes and adaptability to tight development timelines. Less commonly used models, such as Borg Gall and Dick Carey, feature in only 10% of cases, likely due to their complexity and resource demands. Most studies focus on producing contextually relevant teaching materials, such as ethnoscience-based modules, interactive tools, and multimedia resources that incorporate elements of local wisdom. The integration of local cultural knowledge into science learning enhances students' understanding of abstract scientific concepts, cultivates critical thinking, and strengthens cultural appreciation. These findings emphasize the value of culturally responsive approaches in designing science education materials that connect traditional wisdom with contemporary scientific perspectives. In summary, the ADDIE and 4D models are pivotal in fostering culturally relevant science education in Nusa Tenggara. Their practical and systematic frameworks enable the effective integration of regional culture into science curricula, supporting the creation of impactful and contextually aligned educational practices.   Keywords: science learning, local wisdom, ethnoscience, ADDIE model, 4D model, Nusa Tenggara, systematic literature review.

Abstract

In humans, micronutrients are special nutrients that are supposed to be obtained from diets in small amounts to aid body functioning, growth, and development. Micronutrients deficiency results due to low dietary nutrients intake and is currently a worldwide threat that affects humans in various ways, including learning or brain functioning. Sokoto State Nigeria due to its peculiarities such as arid land, poverty, poor education, single-diet nutrition, etc. should be of great risk of micronutrients deficiencies. The objective of this review paper is concerned about micronutrients deficiencies with regards to Sokoto State Nigeria and consequences on brain function. Micronutrients prevalence in Sokoto Nigeria, micronutrients in foods, insufficiency of nutrients in soil, consequences of excess micronutrients, micronutrients deficiencies, causes, etc. were described. Multifold approach to this myriad task should be put forward and tackled head-on; otherwise, the society (Sokoto) will languish continuously with maternal and child mortalities, abnormalities, mental derangements, aa well as poor productivity..
