Abstract
This study aimed to produce a learning trajectory in pyramid material to foster students\u27 spatial ability through realistic mathematics education. This is design research which consists of three stages, namely experimental preparation, teaching experiment, and retrospective analysis. The research subjects were students of class VIII in a junior high school in Aceh Besar, Indonesia. The trial of Hypothetical Learning Trajectory (HLT) for cycle 1 that was performed offline involved three students and the trial of Hypothetical Learning Trajectory (HLT) for cycle 2 that was performed online involved 10 students. The instruments for data collection were student activity sheet (worksheet), observation sheet, interview protocol, field note, and learning video recording. The research produced a pyramid learning trajectory obtained from revising HLT by presenting more pyramid models in everyday life, drawing more pyramid nets, recognizing patterns in determining the number of face diagonal, and displaying 3D animations through GeoGebra. The pyramid learning trajectory started from drawing a pyramid, drawing the net of a pyramid, finding formulas related to the relationship between pyramid elements, finding the formula for the surface area of a pyramid, and finding the formula for the volume of a pyramid. The developed learning trajectory, theoretically, could foster students\u27 spatial ability through realistic mathematics education on the learning material about pyramid
Mathematical model of cholera spread based on SIR: Optimal control
No full textThe bacterium Vibrio cholerae is the cause of cholera. Cholera is spread through the feces of an infected individual in a population. From a mathematical point of view, this problem can be brought into a mathematical model in the form of Susceptible-Infected-Recovered (SIR), which considers the birth rate. Because outbreaks that occur easily spread if not treated immediately, it is necessary to control the susceptible individual population by vaccination. The vaccine used is Oral Vibrio cholera. For this reason, the purposes of this study were to establish a model for the spread of cholera without vaccination, analyze the stability of the model around the equilibrium point, form a model for the spread of cholera with vaccination control, and describe the simulation results of numerical model completion. Based on the analysis of the stability of the equilibrium point of the model, it indicates that if the contact rate is smaller than the sum of the birth rate and the recovery rate, cholera will disappear over time. If the contact rate is greater than the sum of the birth rate and the recovery rate, then cholera is still present, or in other words, the disease can still spread. Because the spread is endemic, optimal control of the population of susceptible individuals is needed, in this case, control by vaccination, so that the population of susceptible individuals becomes minimum and the population of recovered individuals increases

Discovering the lived experiences of graduate students in the virtual space: Reflections and lessons from a phenomenological inquiry
No full textThe COVID-19 pandemic has radically reshaped the academic life of graduate students and revealed the inequities in the traditional education system in the Philippines. This study is a qualitative navigation of the lived accounts of development communication (devcom) graduate students at the University of the Philippines Los Baños. It foregrounds devcom as a field of theory and practice in honor of its pioneer Professor Emeritus Nora C. Quebral and her contribution to the ferment of the field. The credence of phenomenology informed the direction of this research in addressing a paucity of literature that examines the experiences of graduate students on remote learning within the current milieu. The transition of academia into a new phase of development surfaced stories of personal and academic struggles. As social beings, they engage virtual and real spaces in coping that redirect them to a sense of purpose and semblance of normalcy at a time of uncertainties. To address their recurring and emerging conditions is the cultivation of institutional support and online forms of communication support as two pivotal forms of their reflective recommendations. Drawing from the participants\u27 reflections, I developed a schema that investigates the intersectionality of their struggles, coping, and recommendations towards a conducive remote learning milieu
