Abstract

The aim of the study was to design a theoretical approach to the existing techno-ontological logical emotions of university mathematics teachers working in universities in Ecuador. The research was qualitative. For the selection of the sample, a random selection was carried out under the criterion of intentionality. Twenty (20) students and eight (8) mathematics teachers from different universities participated. For data collection, we used a participatory digital observation guide and an open-ended interview. Three categories emerged from the results: the andragogic retrotopia of being a mathematician, the emotional scar in teacher training and the educational perception of the university student. We conclude with a theoretical approach in which the deficit of professional digital training in mathematical sciences allows the emotional logic of the Ecuadorian teacher to drive him/her to portray an academic being that generates hatred and rejection in the university educational community.

Abstract

Learning mathematics at Muhammadiyah Ambon Junior High School tends to be monotonous and does not motivate students. The teacher in his learning only conveys the material he teaches, regardless of the level of understanding of the student. One of the better ways that can encourage students to be actively involved in finding concepts in the teaching and learning process is to do learning using a spiral approach. With a spiral approach in teaching and learning activities oriented to students. The learning process starts from the easy and concrete and goes into the difficult or abstract. That way, it will train the mindset of students in solving every problem in the world of mathematics. This research aims to find out the differences in student learning outcomes between students who are taught using the spiral method and the teaching method of the concept of class VII of Muhammadiyah Ambon Junior High School. The type of research used is quantitative with a sample of 56 people consisting of a control class of 28 people and an experimental class of 28 people. The instruments used are tests and observations. Tests are used to determine the learning outcomes of students who are taught using lecture methods and spiral and observation methods are used to find out the learning conditions that take place. The data analysis technique used is to use two-party t-tests. Based on the results of the data analysis, it was obtained that there were differences in student learning outcomes between students who were taught using spiral methods and lecture methods of the concept of class VII of Muhammadiyah Ambon Junior High School. The results are based on the results of hypothesis testing conducted using the t-test with the result of thitung obtained a value of 7.024. While the conversion result based on the t value distribution table is in the two-party test with db = 54, obtained a ttabel value of 2,000. In other words it can be said that –ttable ≤ tvalue > ttable or -2,000≤ 7,024 > 2,000
