The Importance of Visual Illustrations in Recommended Primary and Secondary School Textbooks in Calabar

Abstract: Many recommended primary and secondary school textbooks in Nigeria do not include visual illustrations that areadequate in terms of their relevance to the social and cultural reality of most pupils and ability to fully capture narratives and ideasin an interesting way that can excite children in the learning environment This study sort to find out the roles visual illustrations intextbooks, as instructional materials, play in teaching and learning in Nigerian primary and secondary schools In terms ofmethodology, pupils and teachers in three schools, Hillcrest High, Big Qua Girls and Aunty Margaret, all in Calabar metropolis,were randomly sampled to find out the importance of visual illustrations in teaching and learning processes The result indicatedthat 30 (or 100%) of the teachers in the 3 secondary schools believe that cartoons and illustrations are vital in the learningprocess; and 52 (or 867%) of the responding pupils believe that visual illustrations in textbooks help them to learn The researchconcludes that primary and secondary school authorities in Nigeria need to demand not just for culturally relevant visualillustrations, but also for visuals that adequately and interestingly formulate stories and ideas inherent in recommended textbooksThe study also suggests that it is important for government to make and enforce policies concerning the inclusion of culturallyappropriate and visually adequate illustrations in recommended primary and secondary school textbooks

An Overview of Cholera Epidemiology: A Focus on Africa; with a Keen Interest on Nigeria

Abstract: Cholera is still a problem in the world today. A huge population of deaths due to cholera disease still occur in Sub-Saharan Africa (Nigeria most especially), Asia, the Americas and other developing countries, where approximately 1.7 billion inhabitants are still served by faecally polluted water sources. Approximately, 2.4 billion inhabitants of these areas of the world lack the majorly required sanitary conditions of living. Legros, asserts that, as of 2019, about forty-seven countries of the globe, are still affected by cholera. Raw or undercooked, contaminated seafood, serves as a vehicle for the transmission (especially to non-endemic areas). A Case Fatality Rate of 4.87% was recorded from 34 Local Government Areas of Bauchi, Borno, Kaduna, Kano and Zamfara state in Nigeria by the 34 th week, in 2018, while 298 confirmed cases and 38 deaths (CFR 1.5%) were recorded from three Local Government Areas in two States (Adamawa & Borno) by Epidemiological week 41 in 2019. Cholera in some cases is regarded as a “disease of the poor” because the populations most affected are those that cannot afford to provide the basic health facilities for themselves. For example, waste management systems, and good accommodation with toilet facilities (the living and health conditions of the people) are wanting. In 2017, A Global Roadmap to 2030 was launched by the Global Task Force on Cholera Control (GTFCC Ending Cholera) to decrease the death rate due to cholera by 90%. By so doing, the disease can be eradicated from at least half of the 47 cholera-affected countries. The objectives of this roadmap are: to fortify health Review Article Ebob; IJTDH, 40(3): 1-17, 2019; Article no.IJTDH.54222 2 systems, water, sanitation and hygiene (WASH), and to coordinate different ways by which cholera can be controlled in these countries by 2030 (ensuring early detection and prompt response to contain outbreaks). This review aimed to understand the epidemiology of cholera in Nigeria, Africa and the world at large, to access the level of spread, management and preventive measures so far implemented in the endemic regions.

Determination of pathogenicity of choanephora cucurbitarum (berkeley and ravenel) thaxt, amongst commonly cultivated vegetables in calabar, cross river state, nigeria

Abstract: Choanephora cucurbitarum is a plant pathogenic fungus with a wide host range. The fungus was isolated from rotting fruits of Capsicum anuum, after it was observed that some vegetables were infected in the farm. The role of infection courts on severity was determined by inoculating the pathogen into soil, leaves and stems of the test plants. The test plants used were Abelmoschus esculentus, Amaranthus sp, Cucumis sativus and Vigna unguiculata. Determinants of pathogenicity were plant height, leaf reduction, fresh and dry weight. Results showed that the fungus was pathogenic to the test plants. A significant reduction in height, leaves, fresh and dry weight of the test plants was observed when compared with the control. The greatest effect of the pathogen was on the inoculated stem of the test plants with a mean of 42.94. The least effect was observed on infected soil with a mean of 92.99. Cucumis sativus showed the least effect by the pathogen with a mean of 84.18, while Abelmoschus esculentus showed the greatest effect with a mean of 44.59. The pathogen showed the greatest effect on leaves of Cucumis sativus with a mean of 20.45, while the least effect was on Vigna unguiculata with a mean of 36.77.Fresh weight ranged from 3.35g to 37.40g, Dry weight 2.15 to 7.90g as compared with the control which had a fresh weight of 7.0g to 57.25g and 3.8g to 11.90g for dry weight. Symptoms such as leaf blight, blight of the shoot apex, soft rot of stems, die back and decay of Vigna unguiculata pods were observed.
