This study aims to determine the effect of using Excel and SPSS on student learning outcomes in advanced statistics courses. This type of research is quantitative research with experimental research ...designs. The action taken is an effort to develop learning technology, namely the constructivism learning approach that is packaged in statistical learning through the use of Excel and SPSS. Based on the analysis of learning outcomes data from statistical learning without the help of programs, with the help of Excel and SPSS programs, there is no significant effect of using Excel and SPSS programs on student learning outcomes. There are several things that cause the use of Excel and SPSS programs do not affect student learning outcomes, namely (1) Inadequate infrastructure, (2) students 'basic statistical skills are still low and (3) students' interest in learning statistics is still low.
This research was motivated by the low learning outcomes of students in the fifth grade mathematics subject at Madrasah Ibtidaiyah Nahdlatul Ulama Bululawang in statistics material. The purpose of ...this study is to improve student learning outcomes through the inquiry method. This research uses Classroom Action Research (CAR) with a quantitative approach. The results of this study indicate that in the cognitive domain in the first cycle the class average reaches 69 with a completeness percentage of 65%. In cycle II the class average increased to 76 with the percentage of completeness of 74%. Whereas in the psychomotor domain in the first cycle an average of 88 with a completeness percentage of 78% and in the second cycle an average of increased to 95 with a percentage of 87% completeness. So it can be concluded that the implementation of the inquiry method can improve student learning outcomes.
Penelitian ini bertujuan untuk mendeskripsikan kemampuan komunikasi matematis siswa mengenai materi statiska menurut teori bruner. Metode yang digunakan dalam penelitian ini adalah penelitian ...kualitatif dengan pendekatan deskriptif. Subjek dalam penelitian ini adalah siswa/i kelas XII IPA 3 di SMA Negeri 2 Klari dengan jumlah 22 siswa dengan tahap awal pengumpulan data menggunakan instrumen tes berupa soal uraian materi stastistika dan instrumen non tes berupa angket. Selanjutnya tahap kedua yaitu pengambilan 3 subjek penelitian menggunakan teknik purposive sampling dimana masing-masing subjek mewakili kategori kemampuan komunikasi tinggi, sedang, dan rendah berdasarkan hasil tes dan non tes. 3 subjek diambil untuk dikaji lebih dalam terkait kemampuan komunikasi matematis dalam menyelesaikan soal menurut proses kognitif bruner. Data yang terkumpul kemudian dianalisis menggunakan model interaktif yang diterangkan oleh Miles dan Huberman yaitu peneliti melakukan reduksi data, menyajikan data, kemudian membuat kesimpulan mengacu pada jawaban rumusan masalah penelitian. Hasil penelitian ini adalah kemampuan komunikasi siswa menurut teori bruner masih rendah menuju sedang, pada tahap informasi siswa rata-rata mampu menuliskan informasi yang didapat dari soal artinya siswa mampu mengkomunikasikan apa yang diketahui dan apa yang ditanyakan soal walaupun sebagian siswa melewatkan tahap ini. Pada tahap transformasi, kebanyakan siswa tidak bisa mengkomunikasikan atau menjelaskan secara tulisan strategi penyelesaian soal walaupun informasi yang didapat sudah benar. Pada tahap akhir evaluasi dikarenakan kesalahan strategi penyelesaian maka hasil evaluasinya tidak sesuai dengan yang diharapkan.
Opportunity theory is a branch of mathematics concerned with opportunities, analysis of random phenomena. The main objects of opportunity theory are random variables, stochastic processes, and ...events: a non-deterministic mathematical abstraction of measurable events or quantities that can be either single events or develop over time in seemingly random modes. If individual coins throw or dice rolls are considered random events, then if repeated sequences of random events will show certain patterns, which can be learned and predicted. Two representative mathematical results illustrating such patterns are the laws of large numbers and the central limit theorem. As a mathematical basis for statistics, probability theory is important for many human activities that involve quantitative analysis of large sets of data. The method of opportunity theory also applies to complex system descriptions given only partial knowledge of their country, as in statistical mechanics. A great discovery of twentieth-century physics is the nature of probability of physical phenomena on the atomic scale, described in quantum mechanics.
This study aims to develop an interactive digital module using Learning Management System (LMS) application with moodle during the Covid-19 pandemic. The research method used in this research is ...research and development (R&D) with the ADDIE development model that consists of five stages, namely Analyze, Design, Development, Implementation, and Evaluation. The results of this study show that interactive digital modules for applied statistics courses are suitable for use as learning media during the Covid-19 pandemic based on validation results by learning media experts, material experts, lecturers, and students.
The purpose of this research is to develop learning media in the form of videos using the sparkol videoscribe application which is appropriate to help the mathematics learning process in statistics ...material. This research method uses development research with the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation) but the researchers only use three stages, namely Analysis, Design, and Development. The instruments used in this study were interview guidelines and validation sheets consisting of material expert validation sheets, media expert validation and linguist validation. Data analysis using descriptive statistics in the form of calculating the average score. Based on the results of the study, an assessment of the videoscribe media from the material expert assessment obtained a valid category with a percentage of 91.87%. The media expert's assessment got a valid category with a percentage of 93.35%. The assessment of linguists is in the valid category with a percentage of 93.74%. From these results, the developed videoscribe media is in the valid category so that the videoscribe learning media can be used in the classroom.
Penelitian ini bertujuan untuk mendeskripsikan komunikasi matematis tulis siswa dalam mengerjakan soal cerita statistika. Penelitian ini menggunakan metode kualitatif dengan jenis penelitian ...deskriptif. Subjek pada penelitian ini yaitu 20 siswa kelas IX SMPN 4 Pujon yang dipilih melalui hasil siswa mengerjakan soal matematika. Teknik yang digunakan untuk pengumpulan data pada penelitian ini yakni memberikan soal cerita statistika kepada 20 siswa kemudian melakukan analisis data dengan melihat kemampuan komunikasi matematis tulis siswa berdasarkan indikatornya. Kemudian mengelompokkan siswa menjadi tiga yang terdiri dari kemampuan komunikasi matematis tulis tinggi, kemampuan sedang, dan kemampuan rendah. Hasil pada penelitian ini yakni satu siswa mempunyai kemampuan komunikasi kategori sedang yang mana menuliskan jawaban kurang tersruktur. Empat siswa memiliki kemampuan komunikasi matematis kategori rendah yang menjawab soal tidak tersruktur dan menulis notasi matematika secara kurang tepat. Sebanyak 15 siswa memiliki kemampuan komunikasi matematis tulis kategori tinggi yang memenuhi semua indikator komunikasi. This study aims to describe students' written mathematical communication in working on statistical story questions. This research uses qualitative methods with descriptive research type. The subjects in this study were 20 students of class IX at SMPN 4 Pujon who were selected through the results of the students working on math problems. The technique used for data collection in this study was to provide statistical story questions to 20 students then analyze the data by looking at the students' written mathematical communication skills based on the indicators. Then group the students into three which consist of high written mathematical communication skills, moderate abilities, and low abilities. The results of this study were that one student had a moderate category of communication skills which wrote less structured answers. Four students have low category mathematical communication skills who answer unstructured questions and write mathematical notations incorrectly. A total of 15 students have high category written mathematical communication skills that meet all communication indicators.
