Study on the Effect of CORE (Connecting, Organizing, Reflecting and Extending) Learning Model on Mathematics Learning Outcomes of Cognitive Domain

Abstract

In the world, mathematics education is one of the fields of study that occupies an important role in creating students who think logically, rational, critical and insightful. Therefore, mathematics is indispensable everyday life and a provision in the face progress of science and technology. This study aimed to assess the effect of the learning model CORE towards mathematics learning outcomes, especially those in the cognitive aspects-this research conducted at Junior High School 34 Pekanbaru with a quasi-experimental type of research. The study design uses a nonequivalent control group design with a sample of all students in class vii-1 (control class) and class vii-2 (experiment class). Data collection techniques using test techniques, observation techniques, and documentation techniques. While the data collection instruments used were a test sheet and observation sheet. Student learning outcomes tests were analyzed using descriptive statistical data analysis and inferential statistical data analysis. Results of data analysis descriptive study gained an average of learning outcomes posttest experimental classes (VII-2) = 83.70, and grade control (VII-1) = 68.02, whereas the results of t-test analysis showed that the experimental class (VII-2) is higher than the control classes (VII-1) seen from the values that t count (3,81) ˃ t table (68,02) with significance level α = 0,05. So it was concluded that the CORE model influences mathematics learning outcomes, especially on cognitive aspects.

Math Modeling and Case Solving in Real Context: Case Study at Xuan Giang High School, Soc Son District, Hanoi City, Vietnam

“…For the group of students who have been fostered in the ability to Mathematic model in the teaching process, they have solved situations close to teachers' expectations. These findings coincide with those obtained by [16], [17], [18], [19].…”

Description of Physics Problem-solving in the Topic of Static Fluid: Case Study of Physics Education in Halu Oleo University

“…Learners have requirements in different forms of knowledge essential to deal with the question of research, declarative knowledge (facts and concepts), operational knowledge (how to use facts and concepts in the processes or procedures) and strategic understanding) [8] [9]. Most students try hard to resolve complex problems and problem-solving strategies in schools are just the appropriate method or technique to solve organized and algorithmic problems that are taught in schools and universities [10], [11]. Students at the college level also have great difficulties solving problems, while the resolution of problems is an important part of most physics classes.…”

Augmented Reality Learning in Mathematics Education: A Systematic Literature Review

“…Bloom's Taxonomy indicates that the classification of effectiveness is in the domain of cognitive, affective, and psychomotor. Concerning our second research question, this study found that mathematics relied upon cognitive domain as it consisted of several aspects: knowledge, comprehension, application, analysis, synthesis, and evaluation which were crucial in learning (Syahtriya Ningsih et al, 2019). Thus, this study discovered significant influence on students' interest through the implementation of AR learning by its ability to apply visualisation in mathematics, while allowing students to keep up with technology advancements.…”
