The effectiveness of pro-math challenge module to improve knowledge, perception, attitude and inclination of students in mathematics subject / Anis Zafirah Azmi ... [et al.]

This paper presents an empirical finding from a research that implementing a Pro-Math Challenge module for form three students in Sekolah Menengah Kebangsaan Gunung Rapat Setia, Ipoh, Perak Malaysia. The objective of this study is to identify the effectiveness of the module in improving students’ mathematical knowledge, which categorized as the Science, Technology, Engineering and Mathematics (STEM) proficiencies. Implemented in a STEM program, the students’ responses on the module were analyzed with a questionnaire survey to measure four criteria namely knowledge, perception, attitude and inclination. The results from a Wilcoxon Signed-rankas test have revealed that each of the criteria has a statistically significant difference on the increment of students’ understanding after the Pro Math Challenge module was implemented. Overall, half of the students strongly agree that the Pro-Math Challenge module implemented in the STEM program was beneficial to them and has given a good impact to them

Intraguild predation model with disease

Ecosystem stability is an important issue in conservation of biodiversity. The stability of predator prey systems or competitive systems has been studied extensively. Although the two fields have been the subject of widespread research recently, no work has been done to study the effect of a disease on an environment where three species; predator, prey and resource present. Here we analyze modification of Intraguild Predation (IGP) model to account for a disease spreading among prey. We chose the simplest epidemiological model, SI model. Here, we consider the simple mass action incidence. We analyze the stability equilibrium points by using Ruth-Hurwitz criteria. Numerical examples will be introduced to show the stability point. The result seems to indicate that either the disease dies out or both species eventually become infected
