Abstract

The reseacrh of effect using Google Classroom as an LMS learning on student learning outcomes in Tondano City is an experiments carried out at several schools in Tondano City where the used of online learning platforms has been widely used by students due to the Covid-19 pandemic in 2020 in Indonesia.. This research was conducted at SMA Negeri 1 Tondano and SMA Negeri 3 Tondano with the sample chosen not randomly but with a specific aim, namely to see the equality between the control class and the experimental class. The purpose of this study was to determine the effect of using google classroom as an online learning application on student learning outcomes in Tondano City. The research method used is a quasi-experimental research with the form of nonequivalent control group design where there is one experimental group and one comparison group or control group by being given tests before and after treatment (treatment). Data on cognitive learning outcomes were analyzed using parametric statistics, namely the calculated homogeneity test, normality test, t test and N-gain, so it can be concluded that there is an effect of using Google Classroom on the learning outcomes of High School Students in Tondano City

Abstract

Graceful labeling, first introduced by Rosa as β-labeling. A graceful labeling (or β-labeling) on a graph G involves assigning labels to its set of vertices, forming an injective function f that maps each vertex to the set of non-negative integers {0, 1, 2, ..., |E(G)|}, where |E(G)| denotes the number of edges in G. This induces a bijective function f* that maps the edges of G to the set of positive integers {1,2,...,|E(G)|} which the edges label obtained by absolute number of the subtraction between 2 neighboring vertex labels. One renowned conjecture proposed by Kotzig-Ringel-Rosa, known as the Graceful Tree Conjecture (GTC), posits that all trees are graceful. To this day, this remains an open problem, challenging researchers to substantiate its validity. The quest for graceful labeling, particularly for specific types of trees, continues to be an active zona of research. Notably, caterpillar graphs have been established as graceful. It is worth noting that not all graphs possess a unique labeling. For instance, in the case of graceful labeling for caterpillar graphs, there exist four distinct methods, which will be elucidated algorithmically in this article. By demonstrating various approaches to labeling caterpillar graphs, it is hoped that this concept can be extended to other graceful labelings, ultimately contributing to the identification of more graceful trees

Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh penerapan metode pembelajaran gamifikasi terhadap hasil belajar siswa pada Materi Gerak dan Gaya di SMP Katolik St. Rosa de Lima Tondano. Subjek penelitian adalah siswa kelas VII berjumlah 11 orang. Metode penelitian yang digunakan yaitu one-group pretest-posttest design sebagai salah satu bagian dari pre-experimental design. Peneliti bekerjasama dengan guru mata pelajaran, wali kelas dan mahasiswa Kampus Mengajar Angkatan 6 Kemendikbudristek tahun 2023 yang ditempatkan di SMP Katolik St. Rosa de Lima Tondano. Penelitian ini dilakukan secara luring yaitu pembelajaran tatap muka dalam kelas dengan mengambil mata pelajaran Ilmu Pengetahuan Alam (IPA) di kelas VII semester genap TA. 2023-2024. Adapun penerapan metode gamifikasi secara offline yaitu permainan ular tangga yang dimodifikasi untuk materi Gerak dan Gaya dan gamifikasi secara online yaitu menggunakan kahoot untuk evaluasi belajar. Berdasarkan hasil analisis data yang berdistribusi normal dengan uji paired sample t-test dapat disimpulkan bahwa terdapat pengaruh yang signifikan melalui penerapan metode gamifikasi dalam pembelajaran terhadap hasil belajar siswa kelas VII SMP Katolik St. Rosa de Lima Tondano. Hasil N-gain scor menunjukkan kategori capaian sedang pada persentase 41% dimana menunjukkan bahwa penggunaan gamifikasi dalam pembelajaran telah dilaksanakan secara efektif pada kategori sedang dalam beberapa keadaan penting dan telah dilaksanakan dengan baik.

Mikhael Rian Vernando Lioso. 22504061.. The Relationship of Self-Confidence in Learning Mathematics with Students' Mathematics Learning Outcomes. Department of Mathematics. FMIPA. UNIMA. 2023. This study aims to determine the relationship between self-confidence and students' mathematics learning outcomes. This research uses a quantitative approach with a correlational survey method. The subjects of this study were all VIII grade students of SMP Negeri 4 Suluun Tareran in the 2023/2024 school year with a population of 40 students and a sample of 37 students. Self-confidence data is obtained from a questionnaire distributed to students, while learning outcomes data is obtained through documentation of odd semester midterm exam results in the 2023/2024 school year. The data analysis technique uses a simple correlation technique, with α = 0.05. as for the results of the research obtained is that there is a positive relationship between self-confidence and student mathematics learning outcomes by 29.7%, which means significant

Abstract

Graph theory is a topic in mathematics that is still relatively new and developing rapidly. Graph theory is used to simplify and solving problems like connection, networking, travelling or flow. One of the very interesting topics in graph theory is graph labeling. Graceful labeling first introduced by Rosa as β-labeling. A graceful labeling (or β-labeling) on a graph G involves assigning labels to its set of vertices, forming an injective function f that maps each vertex to the set of non-negative integers {0, 1, 2, ..., |E(G)|}, where |E(G)| denotes the number of edges in G. This induces a bijective function f* that maps the edges of G to the set of positive integers {1,2,...,|E(G)|} which the edges label obtained by absolute number of the subtraction between 2 neighboring vertex labels. The Graceful Tree Conjecture (GTC) posits that all trees can be gracefully labeled, a hypothesis still unproven. The quest for graceful labeling, particularly for specific types of trees, continues to be an active zona of research. One of the graph that already proven can be labeled with graceful labeling is star graph. Now we gonna prove graceful labeling for star graph, if each leaf in the star graph is connected to m new leaves. We call it multi-level star graph. Exploring these methods aims to extend the concept to other graphs, contributing to the identification of more gracefully labeled trees.

Abstract

Penelitian ini bertujuan untuk menguji keefektifan model pembelajaran Creative Problem Solving (CPS) dalam meningkatkan hasil belajar siswa pada materi lingkaran, dibandingkan dengan model pembelajaran Direct Instruction. Penelitian dilaksanakan di SMP Negeri 4 Tombatu pada tahun ajaran 2023/2024 dengan melibatkan dua kelas yaitu kelas eksperimen dengan menggunakan model CPS dan kelas kontrol dengan menggunakan model Direct Instruction yang masing-masing berjumlah 21 siswa. Desain penelitian yang digunakan adalah quasi eksperimen dengan pendekatan Posttest-Only Control Design. Hasil belajar siswa diukur melalui tes post-test setelah pembelajaran. Data hasil post-test dianalisis menggunakan uji-t untuk menguji perbedaan rata-rata kedua kelompok. Hasil penelitian menunjukkan rata-rata hasil belajar siswa pada kelas eksperimen dengan menggunakan model CPS sebesar 81,428, sedangkan kelas kontrol dengan menggunakan model Direct Instruction mencapai 69,333. Hasil uji-t menunjukkan t-hitung sebesar 3,150, lebih besar dari t-tabel sebesar 1,683, yang berarti bahwa model CPS lebih efektif dalam meningkatkan hasil belajar siswa pada materi lingkaran. Selain itu, penerapan model CPS membuat siswa lebih aktif dalam belajar, meningkatkan kerjasama kelompok, dan mendorong pengembangan keterampilan berpikir kritis dan kreatif. Penelitian ini menyarankan penerapan model CPS dalam pembelajaran matematika di sekolah untuk meningkatkan hasil belajar siswa dan mengembangkan keterampilan berpikir kritis. CPS dapat memberikan pengalaman yang lebih interaktif dan menyenangkan bagi siswa dalam memecahkan soal matematika.
