The paper considered developing a constructivist model for effective physics teaching. The model is imperative because of the increasing difficulty in learning physics and the resulting poor academic performance in the subject. The paper reviewed two types of constructivism which are the social and cognitive constructivism. Highlights of correlations between the constructivist learning and the authentic learning were revealed. To applying the model to physics learning, it was argued that constructivist teachers should give serious attention to the prior knowledge of (...) the students. This will determine the mode of teacher instruction. The teacher content knowledge and pedagogical knowledge are central to excellent teaching. The paper concludes that physics teacher should promote student interactions and respect student ideas being the kernel of the constructivist learning.

The present study was carried out to revive the old art of dyeing with natural dye obtained from barks of Bombax ceiba Linn. locally known as semal tree. The commercialization of the present process will be helpful for their viable application in handloom and textile industries. Further, this will also have great impact especially for the economic growth of the rural dyer communities. In the present study, Cotton fabric was pre treated with eco friendly and non eco friendly mordants. The (...) various shades were obtained. The name of the shade and shade code was obtained by matching the shade card presented by Asian paint India. Colour strength of dyed cotton fabric was measured in terms of L, a, b colour scale by using hunter lab instrument Hunterlab EasyMatchQC Colour flex EZ 45 0, Reflectance . mode. The dyed samples have shown good to excellent and poor to good fastness properties Dr. Yogesh Vadwala | Dr. Namrita Kola "Dyeing of Cotton with Natural Dye Obtained from Barks of Bombax Ceiba Linn locally known as Semal" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-1 | Issue-4 , June 2017.

The paper assessed the nutritional knowledge and cultural food beliefs on dietary practices of pregnant women in Epe Local Government Area, Lagos State, Nigeria. A descriptive research design was adopted for this study. The population of the study consisted of all registered pregnant women in seven (7) antenatal clinics in Epe Local Government Area of Lagos State. A sample size of 270 was drawn using proportionate sampling technique. The collected data were analyzed using frequency, percentage, and the Chi-square test of (...) association. The significance level was set at p < 0.05. The results showed a statistically significant relationship between knowledge of nutrition and dietary practices, χ2 (2) = 78.201, p<0.05. However, there was no statistically significant relationship between cultural food beliefs and dietary practices, χ2 (1) = 1.151, p>0.05. The finding also showed that cultural food beliefs do not influence the dietary practices of pregnant women. The study recommends that the government and health agencies should continuously train health workers on nutritional issues, particularly on how to enhance the nutritional knowledge of expectant pregnant women prior to conception. This will help potential mothers improve their dietary practices. (shrink)

Mucilage are bio-substances derived from plants or microorganisms that have positive effects on health, including boosting the immune system, calming the gastrointestinal tract, and decreasing blood pressure. Overall, recent developments in mucilage research have shown the materials’ potential for usage in variety of other fields, including adhesion or binding, textiles, papers, etc. However, there is limited widespread knowledge on the characteristics and use of mucilage in adhesion, textile, and paper industries. Therefore, this review navigates through the mucilage's chemical structure, and (...) thermal, mechanical, physiochemical, and phytochemical features, weaving together their advanced applications. As the scientific community continues to unravel the advantages of mucilage extracts and harness their untapped potential, this review serves as both a testament to past achievements and a beacon guiding researchers towards a future enriched by the possibilities they hold.

This study examined students’ perception of rape and sexual violence and methods of prevention in tertiary institutions in Lagos State. It was a cross-sectional study carried out among one thousand, two hundred and eleven (1,211) female undergraduates selected from two tertiary institutions in Lagos State. The sample size for the study was one hundred and twenty-one (121) representing 10% of the population. Inferential statistics was used for analysis. The results revealed that majority of the students are aware of the different (...) types of rape but did not consider forced sexual intercourse between spouses as rape. The students have a good knowledge of rape and sexual violence. The students perceive that rape can have detrimental effects on the victims’ mental, physical and reproductive health. Avoiding late nights, dressing decently, increasing the presence of security officers at strategic places on campus and the likes were identified ways of preventing rape in tertiary institutions. Among the recommendations proffered are that students should review their dressing styles to conform to the morals of the society to prevent the occurrence of rape. (shrink)

W niniejszym tekście, poświęconym definiowaniu m. in. słów i zwrotów frazeologicznych podczas nauczania języków, autorka opisuje lingwistyczną teorię Anny Wierzbickiej, dotyczącą Natural Semantic Metalanguage i w adaptacyjnej formie przenosi ją na płaszczyznę zajęć z języka obcego, gdzie przynosi ona namacalne wyniki. Podczas zajęć językowych wymaga się od uczących się poprawnego definiowania ogólnego, które jednak rzadko przekazywane jest w podręcznikach i na wykładach, mimo iż zdolność ta nie jest wcale oczywista, samo definiowanie zaś nie jest łatwym zadaniem. Przeciwnie - od studentek (...) i studentów języków obcych oczekuje się mentalnego uzdolnienia w tym kierunku, nie uwzględniając faktu, że wiele osób ma trudności z definiowaniem nawet w języku ojczystym. W artykule autorka chce pokazać, że po części zignorowana teoria Anny Wierzbickiej ze swoim punktem wyjściowym, jakim są primes, pozwala uświadomić uczącym się języka obcego, że istotę słowa, wyrażenia czy frazy można wyjaśnić w oparciu o sposób określenia znaczenia, przyjęty w NSM. Nie jest przy tym konieczne, ażeby znaczenia opisywać i określać poprzez primes. Ważne jest, aby w celu uniknięcia błędnego koła podczas objaśnień definicji nie koncentrować się na synonimach i antonimach. Jak takie i podobne objaśnienia mogą wyglądać, pokazane jest na przykładach kilku definicji, które wyjaśnione zostały w oparciu o sposób określenia znaczenia przyjęty w NSM. Autorka dyskutuje również opisy i warunki działania takiej metody. Na zakończenie przedstawione są propozycje w zakresie metodologii nauczania umiejętności definiowania podczas zajęć języka obcego.
