Meningkatkan Hasil Belajar Materi Pengukuran Melalui Pendekatan TaRL pada Siswa Kelas 1 SDN Model Terpadu Madani
No full textThis study aims to improve the learning outcomes of first-grade students on measurement topics through the application of the Teaching at the Right Level (TARL) approach at SDN Model Terpadu Madani. This Classroom Action Research (CAR) was conducted in two cycles involving 22 students, consisting of 11 boys and 11 girls. The study results indicated that in Cycle I, only 36% of students met the Minimum Competency Criteria (MCC), while 64% did not. After implementing the TARL approach, students were grouped into three categories based on their ability levels: high, medium, and needing guidance. In Cycle II, there was a significant improvement, with 91% of students achieving competency and only 9% still falling short. These findings suggest that the TARL approach is effective in enhancing students' learning outcomes, particularly in overcoming difficulties in understanding measurement concepts. This approach also successfully creates a more inclusive and adaptive learning environmentPenelitian ini bertujuan untuk meningkatkan hasil belajar siswa kelas satu pada topik pengukuran melalui penerapan pendekatan Teaching at the Right Level (TARL) di SDN Model Terpadu Madani. Penelitian Tindakan Kelas (PTK) ini dilaksanakan dalam dua siklus dengan melibatkan 22 siswa, terdiri dari 11 siswa laki-laki dan 11 siswa perempuan. Hasil penelitian menunjukkan bahwa pada Siklus I, hanya 36% siswa yang memenuhi Kriteria Kompetensi Minimal (KKM), sementara 64% tidak. Setelah menerapkan pendekatan TARL, siswa dikelompokkan menjadi tiga kategori berdasarkan tingkat kemampuannya: tinggi, sedang, dan membutuhkan bimbingan. Pada Siklus II, terdapat peningkatan yang signifikan, dengan 91% siswa mencapai kompetensi dan hanya 9% yang masih kurang. Temuan ini menunjukkan bahwa pendekatan TARL efektif dalam meningkatkan hasil belajar siswa, terutama dalam mengatasi kesulitan dalam memahami konsep pengukuran. Pendekatan ini juga berhasil menciptakan lingkungan belajar yang lebih inklusif dan adaptif

Penerapan Model Pembelajaran Problem Based Learning Terhadap Hasil Belajar Siswa Pada Materi Laju Reaksi Kelas XI di SMAN 6 Palu
Full text linkThis study aims to describe the improvement of student learning outcomes through the application of a problem based learning model on the reaction rate material for class XI SMA Negeri 6 Palu. The type of research used in this research is pre-experimental with one-group pretest posttest design. Sampling in this study by means of purposive sampling. The sample consisted of two classes, namely class XI MIA 1 as experimental class 1 (n=20) and class XI MIA 4 as experimental class 2 (n=19). Data on student learning outcomes was processed using learning effectiveness testing (N-gain). The effectiveness of the application of the problem based learning model to improve student learning outcomes on the reaction rate material can be seen from the average N-gain value in the two experimental classes which are included in the medium category, namely 0.66 and 0.66. The results of the data from the N-Gain test are obtained g = value 0.30 (<g>) <0.70 is in the medium category, which indicates a change in student learning outcomes after the application of the problem-based learning model.Penelitian ini bertujuan untuk mendeskripsikan peningkatan hasil belajar siswa melalui penerapan model pembelajaran berbasis masalah pada materi laju reaksi kelas XI SMA Negeri 6 Palu.

Impact of the Guru Penggerak Programme on Improving Leadership Competence in Numeracy Learning
Full text linkEducation of Guru Penggerak is the Government's innovation to prepare for future leadership transformation. Before becoming a leader, the teacher mobiliser is required to be the main actor in classroom learning and mobilise peers through a community of practice. Thus, they are expected to become leaders in school management and development. Candidate of Guru Penggerak, after undergoing Education and Training for 6 months covering 10 modules, will become student-centred learning leaders. The implementation of quality student-centred learning has not been optimal and equitable from one region to another. The low level of literacy and numeracy in the education report card has led the Government to launch the Merdeka Belajar Programme. The purpose of the research conducted on prospective Guru Penggerak is to determine the impact of Education of Guru Penggerak on improving learning through improving grades during education and increasing competence in self-development and learning leadership, knowing the motivation of prospective Guru Penggerak after completing education and whether literacy and numeracy materials are needed. The research method uses quantitative descriptive research using data collection techniques of interviews, documentation, questionnaires and observations, pre-test-post test scores and questionnaires on prospective Guru Penggerak. The results obtained from this study are an average increase from the pre-test score of 50.80 to the average post-test score of 64.58 or an increase of 13.77. From the questionnaire, the competence of self-development and others increased from 76.82% to 87.35%. For learning leadership competence there was an increase from 73.03% to 85.04
Implementation of Problem Based Learning to Enhance Student Engagement and Learning Outcomes in Fourth Grade Mathematics
No full textThis study aims to enhance student engagement and learning outcomes in mathematics for fourth-grade students at SD Negeri 23 Palu. The research employs Classroom Action Research (CAR) with a quantitative approach. The subjects of the study consist of 25 fourth-grade students. Data were collected through observations and assessments of student learning outcomes. The results indicate that in the pre-cycle, only 33% of students achieved mastery in learning. However, after implementing the Problem Based Learning (PBL) model, the percentage of students who achieved mastery increased to 87% in the first cycle and reached 93% in the second cycle. Additionally, the increase in student engagement is also evident from their involvement in the learning process. In the pre-cycle, no students were categorized as active or very active, with the majority falling into the inactive category. Following the implementation of the PBL model, student engagement improved in the first cycle, where 33% of students were classified as very active and 54% as active. In the second cycle, student engagement further increased, with 87% classified as very active and 13% as active. These findings demonstrate that the application of the PBL model is effective in enhancing student engagement and learning outcomes for fourth-grade students at SD Negeri 23 Palu

No full textThis study aims to determine the effect of synchronous and asynchronous learning on student learning outcomes in computer application courses. The population in this study were students of the Indonesian Language and Literature Education study program at Tadulako University. Sampling was done by purposive sampling technique so that 2 classes were obtained that were normally distributed and homogeneous. This research uses a quantitative approach with a quasi-experimental method. Data analysis used one sample t test with the help of jamovi application. The results showed that synchronous and asynchronous learning can improve student learning outcomes in computer application courses with an average value of 84.9 in the experimental class and 83.6 in the control class. The prerequisite test results obtained p value (0.263) >0.05 in the normality test (Shapiro-Wilk) shows that the data distribution is normally distributed, and the p value (0.889) >0.05 in the homogeneity test (Levane's) shows that the variance of the two data groups is homogeneous. The results of hypothesis testing using independent samples t-test obtained p (0.021) > α (0.05), so Ho is accepted, indicating that there is no significant difference in the average test scores between synchronous and asynchronous learning.Penelitian ini bertujuan untuk mengetahui pengaruh pembelajaran synchronous dan asynchronous terhadap hasiil belajar mahasiswa pada matakuliah aplikasi komputer.
