Abstract

Under-Five Mortality rate refers to the probability a new-born would die before reaching exactly 5 years of age, expressed per 1,000 or 100,000 live births. The Five Child-Killer Diseases used in this study are Pneumonia, Diarrhoea, Measles, Tetanus and Polio. The study used Ex post facto design with quantitative approach. A secondary data of the Five-Child Killer Diseases and Under-Five Mortality were obtained from the twenty-one (21) Local Government Primary Health Care Development Agency in Adamawa State between the periods of 2008 to 2022. The study measured the mortality rate due to the Five Child-Killer Diseases and its Cause-effect on the Overall Under-Five Mortality Irrespective of Diseases in the study area and then develop a model for future prediction. Based on the finding, the Overall Under-Five Mortality rate increases from 112 to 314 deaths per thousand live births between 2008 and 2012, followed by a sudden decrease from 261 to 90 deaths from 2013 to 2016 and then fluctuate throughout the rest of the period under review.  Individually, the largest contributor of Under-Five Mortality among the Five Child-killer Diseases is Diarrhea with 89 deaths per thousand live births in 2011, followed by Measles with 39 deaths in the same year. The regression model revealed a positive and insignificant causal relationship between deaths due to Pneumonia, Diarrhoea and Measles on Overall Under-Five Mortality in the study area. The regression model also explained that; at zero deaths due to the Five Child-Killer Diseases, the Overall Under-Five Mortality is more than 105 deaths in the study area.

Abstract

Reasoning ability is a high-level thinking ability in learning mathematics. Mathematical reasoning and mathematics learning are two things that are interrelated and cannot be separated because mathematical material is understood through reasoning, and reasoning can be trained through studying mathematics. To achieve mathematical reasoning abilities in learning, students need adequate behavior, one of which is learning independence. The aim of this research is to analyze mathematical reasoning abilities based on students' independent learning at SMPN 1 Praya Timur on straight line equations. The method used in this research is qualitative research with descriptive methods. The samples in this study were taken randomly based on the class in the population. The class that the researcher took as a sample in this study was class VIII C at SMPN 1 Praya Timur for the 2023–2024 academic year. The results of this study show that subjects with low reasoning abilities are also categorized as having low learning independence. The learning ability of students who are categorized as moderate turns out to be moderate. So, it can be concluded that the relationship between learning independence and reasoning ability is based on high student learning independence, so their reasoning ability is also high. Based on the results of this research, it is hoped that teachers can develop teaching and practice problem-solving questions to improve students' reasoning abilities
