Abstract

Research has been carried out to find the level of student ability and the level of difficulty of essay questions on fractions, through polytomous data analysis by applying the Rasch model. The research was conducted in the In-Service Professional Teacher Education program, specifically in the Elementary School Teacher Education. The research was conducted at Belang 1 State Elementary School, Southeast Minahasa Regency, North Sulawesi, Indonesia, in grade 6 with a total of 27 students. Experimental research method with one group pretest-posttest design. The experimental treatment is a Problem-Based Learning (PBL) learning model. The test instrument is in the form of an essay with material on adding fractions with different denominators. The instrument was content validated through a video conference forum attended by experts, tutors, and subject teachers. Data was collected through formative pre-tests and post-tests. Scores are processed as polytomy data. Data analysis used the Rasch model with the Ministep 4.3.2 software application. The results of the analysis, as a class group, the pre-test average was 7.0 and the post-test was 77.0. This group's data shows that the use of the Problem-Based Learning (PBL) model in mathematics learning is very effective. Another conclusion is that the Rasch Model can accurately analyze polytomous data and find 1 student who has a high ability exceeding the highest level of test item difficulty in completing the essay test on adding fractions with different denominators. Then the Rasch Model can analyze the level of difficulty of the 5 items of the essay test instrument, it was found that 2 test items had a low level of difficulty. Using the Rasch model, it is consistently detected that adding fractions with different denominators containing the number 7 is categorized as having a high level of difficulty.

Abstract

Innovative learning in the 21st century requires students to have the ability to think critically, creatively, and communicatively and be able to collaborate. For this purpose, research has been carried out on Professional Teacher Education (PPG) students at Manado State University. The research aims to implement the Problem-Based Learning (PBL) and Project Based Learning (PjBL) learning models through Field Experience Program (PPL) activities. The study was conducted on a sample of 36 elementary school teachers with a total sample of 252 students in the Eastern Region of Indonesia, including the provinces of Papua, Maluku, East Nusa Tenggara, West Nusa Tenggara, Central Sulawesi, Southeast Sulawesi and North Sulawesi. Experimental research method with the application of the PBL and PjBL models. Data was obtained from online workshop interviews and the Learning Management System (LMS) owned by the Directorate of Teacher Professional Education, Directorate General of Teachers and Education Personnel of the Republic of Indonesia. The data is processed from the Learning Implementation Plan (RPP) documents and Teaching Modules created by the teacher then reviewing the Teaching Materials, Student Worksheets, Assessment Instruments, and Learning Media. Student learning outcomes are taken from the pre-test and post-test formative scores. The results of the data analysis showed that there was a significant increase in learning outcomes from an average Pre-Test score of 52.2 and after the learning process, the average Post-Test score increased to 84.5. This happened because the PBL and PjBL learning models had been implemented which reached 98.8%. The above learning outcomes occurred because innovative learning elements were implemented, namely 87.7% of learning based on Higher Ordered Thinking Skills, 80% of learning using Group Worksheets, 20% using Individual Worksheets, 67% of learning using Technological Pedagogical Content Knowledge (TPACK) 33% of lessons use TPACK accompanied by Student Books and Teaching Aids. Based on the research results above, the use of PBL and PjBL in learning is a necessity. The PBL and PjBL learning models trigger and encourage students to become more creative in learning by prioritizing collaborative learning and being able to communicate experiences and learning results obtained through analytical and critical thinking.
