Abstract: This study is designed to investigate the influence of menstruation on the academic achievement of senior secondary school Biology students in Irewole Local Government Area of Osun State, Nigeria. In the light of this, three specific objectives and research questions were highlighted not only to achieve but also to answer. The study employed quasi-experimental design. Besides, purposive sampling technique was used to take a sample of sixty-five (65) Grade 11 (Senior Secondary School II) students from three public high school (...) within the study area. The data generated from the instrument that is Biology Achievement Test (BAT) was analysed with the aid of a component of inferential statistics. The findings revealed a significant relationship between the academic achievement of students in Biology and menstruation. This is because, students before their menstrual period had mean score of 45 marks which was slightly higher than the one they had during (that is 42 marks) their menstrual period. A significant association between the academic achievement of students in Biology and menstrual pains was also observed. However, there was no significant relationship between the academic achievement in Biology among participants and duration of menstruation. This means that number of days used to complete menstruation period was insignificant to academic achievement of the participants in Biology. It is inferred from the study that there is relationship between menstruation and students’ academic performance in Biology among public secondary schools. Recommendations such as provision of conducive facilities in schools, constant awareness programme on the subject matter among others were made. (shrink)

The need for technical input, particularly set design in the overall theatrical process cannot be overemphasised in the pursuit of an aesthetically pleasing stage performance. This is because set design (flats and platforms) is the first place of contact irrespective of the medium of production. This work, therefore, examines postmodern trends in set designs within the backdrop of emerging set design concepts and interpretations via the use of sophisticated technology (such as light emitting diode screen, green-hippo software, 3D digital model (...) among others), in our contemporary society, using selected productions in Ultima Studios and Zmirage, Lagos. The study employs the descriptive and participantobservation methods while the interview instrument complements the two methods. The two methods enable us to study the trends, dimensions and techniques of set designs in Ultima Studios and Zmirage, Lagos. This study also relies on relevant journals, articles, textbooks and appropriate internet materials. More so, Sunnie Enessi Ododo’s (2002) Representational and Presentational Performance Styles, is adopted as our theoretical framework. Our findings show that set design for the stage or screen production goes beyond physical set design method to include the virtual set design. Postmodern trends in set design such as media mapping projection set design are also recognised. We also discover that, set design is a make-believe world that requires expertise, experience and professionalism in the process of its artistic utilisation within the postmodern age. The work concludes that, technical experts in the theatre should advance with the new trends of set design for both stage and screen production by studying and learning various trends and dimensions of postmodern set design. The study recommends that postmodern set design should not be downplayed in any production either screen or stage in the Nigerian theatre. (shrink)
