QUALITY ASSURANCE IN POLICY IMPLEMENTATION OF SCIENCE EDUCATION IN NIGERIA: PROSPECTS AND CHALLENGES

Kabiru Isah Inuwa
Read Full Article

Nigeria as a growing nation can only meet up with other developed and industrialized nations when her Educational system is fully developed. It is a fact that no nation grows educationally without adequate implementation of her educational policies since it is not enough just to make policies. Therefore, there is inadequate and management of finance has lead to the inadequacy of training science facility in schools particularly in our institutions of higher learning, teachers are continually under pressure to cover the generally content- heavy syllabus and prepare students adequately to pass the examination often within limited time frame, the explanation for student attitude toward school science may be shortage of well- qualified teachers capable of providing positive experience. This paper focused on concept of science education, educational policy implementation in Nigeria, quality Assurance and it’s important to education, national policy on science education, prospect of science educational policy implementation. Challenges confronting quality assurance in policy implementation of science teacher education were also identified. The paper recommended among others that, for adequate implementation of science education policies, curricula content would have to be amended to reduce dependence on text books and also include the doctrine of an ethno- science. Traditional teaching format in classrooms which focuses on passing examinations should be discouraged and assessment which covers higher levels of cognitive, affective and psychomotor ability be encouraged. Above all, funding should be adequately and promptly provide for the issues of implementation to be carried out.

Abstract The study focuses on the Technology/Engineering field, specifically Technology class of Library of Congress, United States. It is important for a researcher, Technologist, Engineer, Librarian, subject specialist, and other library customers that have interest in the discipline of Technology to know the technology division as the Library of Congress craftily simplied the fields of knowledge. Hence, the main objectives are – to enlighten the technologists/engineers, to increase patronage, to stimulate the initiating body of possible review to make knowledge more accessible to the Library customers. Some suggestions proffered are: the need to make use of library compulsory in all higher institutions. Secondly, the need for the library personnel to reach the Colleges/Departments for collaborations in teaching and academic supports. It is very imperative that Colleges, Faculties and Departments liaise to work together.

TECHNOLOGY CONVERGENCE, MEDIA CONVERGENCE, YOUTH USAGE OF SOCIAL MEDIA AND CONFLICT TRIGGER: A STUDY OF ESCALATION OF THE 2017/2018 MAMBILLA PLATEAU CONFLICT IN NORTH EAST NIGERIA

Social media as a product of technological convergence can be used positively or negatively by people, including youths. Positively, social media helps in opening the participation of everyone in sharing information without much hindrances. Equally, using social media negatively can plunge the society into chaos. This paper looks at youth usage of social media during the 2017/2018 Mambilla Plateau conflict in North East Nigeria, using FGD and In-depth Interview with Technological Determinant Theory and Peace Journalism Conflict Transformation Theory as theoretical framework. The paper revealed that youths wrongly used Facebook to fuel the escalation of the 2017/2018 herders/farmers conflict on the Mambilla Plateau through dissemination of fake news and hate speech. This paper recommends that though youths can be allowed unhindered access to the use of social media, such access should be checked during crisis to avoid misuse that can lead to escalation of such crisis.

IDENTIFICATION OF FUNGAL PATHOGENS CAUSING ROT DISEASES IN IRRIGATED CARROT CROPS AND THEIR IMPACT ON NUTRITIONAL QUALITY

Carrot (Daucus carota L.) is a nutritionally rich vegetable crop, but fungal rot diseases in irrigated systems cause significant yield losses and compromise food safety. This study aimed to identify fungal pathogens associated with rot diseases in irrigated carrot crops and evaluate their impact on nutritional content. Carrot samples from Hunkuyi, Zaria, Nigeria, were analyzed using microbiological and nutritional techniques. Six fungal species were isolated: Aspergillus flavus (41.67%), Aspergillus niger (25%), Candida sp., Rhizopus sp., Phonia sp., and Fusarium sp. (each 8.33%). Nutritional analysis revealed significant reductions in carbohydrates (7.3% vs. 9.6%), proteins (0.8% vs. 1.2%), vitamin C (2.7 vs. 5.9 mg/100g), vitamin A (20 vs. 33.1 mg/100g), potassium (260 vs. 320 mg/100g), and calcium (22 vs. 33 mg/100g) in rotted carrots compared to healthy ones, with increased moisture (91.2% vs. 88.5%) and fiber (27.37% vs. 20.13%). These findings highlight the need for integrated disease management to mitigate economic losses and ensure food safety.

IN VITRO TESTING OF METHANOL EXTRACT OF LUFFA AEGYPTIACA MILL PLANT (CUCURBITACEAE)

Determination of in-vitro effect of Methanol extract of Luffa aegyptiaca seeds and husk on Tadpoles and Sorghum bicolor radicles has been carried out in this research. The research was carried out to find a local remedy for tumor with the anticipation of possible anticancer constituents. The in-vitro cytotoxicity testing of the methanol extract of L. aegyptiaca seeds and husk on Tadpoles at concentrations of 1, 2, 5, 10, 20 and 30mg/ml and Dimethylsulphuroxide (DMSO) was used as Negative control, the result obtained was 23%, 0%, 10% mortality at 1% concentrations within 27minutes and 76%, 63% and 60% mortality at 24hours respectively. While the in-vitro antiproliferative testing of the seeds and husk of L. aegyptiaca part methanol extract carried out at 1mg/ml, 30 mg/ml also inhibited the growth of Sorghum radicles by 99.2% (husk), 98.7% (seeds) and 97.6% (leaf) at 96 hour.The Luffa methanol extract (LAM) exhibited a concentration defendant cytotoxic effect (LD50 = 18 µg/ml) and (LC50 = 20 µg/ml) inhibition of the growth of guinea corn radicles. The phytochemical screening results revealed that the plant parts contained alkaloid, flavonoids, glycosides and tannins. The results obtained from these studies show that methanol extract of the L. aegyptiaca parts have cytotoxic and antiproliferative effects on Tadpoles and Sorghum radicles. The findings testified the basis for the traditional uses of the plant to treat inflammations and tumor related ailments as practiced in Hausa traditional medicine and suggest the probable use of the plant in preparing recipes for tumor-related ailments.

AN EVALUATION OF LUFFA AEGYPTIACA MILL PLANT LEAVES (CUCURBITACEAE)

This study is aimed at contributing more elaborate ways for authenticating Luffa aegyptiaca Mill (Cucurbitaceae) plant by studying the leaves through the use of Light microscope to undertake Pharmacognostic evaluations of Luffa aegyptiaca Macroscopical, Microscopical, Physical Constants, Preliminary Phytochemical Screening and Thin Layer Chromatography were employed. Studies of the leaf revealed the presence of anomocytic stomata and covering trichomes at the lower and upper surfaces. Stomatal number and stomatal index; 14.09 ± 1.35 and 6.3 ± 0.12, vein islet and Veinlet termination; 9.6 ± 0.09 and 21.8 ± 0.07 were observed and recorded respectively. Physical constant studies on the leaf showed moisture content of 10.36 ± 0.12%, Ash value of 13.3 ± 0.21%, Acid insoluble ash 9.03 ± 0.12%, alcohol and water extractive values; 2.07 ± 0.13g and 4.73 ± 0.7g respectively. Preliminary Phytochemical screening of the leaf, revealed the presence of alkaloids, flavonoids, saponin, tannin, anthraquinone, cardiac glycoside, coumarins and carbohydrates. Thin Layer chromatography of the leaf methanol extract showed 12 spots of variable colors with P-Anisaldehyde and 3 spots with ferric chloride spraying reagents these are indications for the presence of the above mentioned secondary metabolites as observed during phytochemical screening. These characteristics and parameters add courage and value to the community usage of the plant for medicinal purpose traditionally. For the research is an important factor to detect adulteration and could help in the classification and identification in plants taxonomy.
