Teaching and learning science during the early years

Over the past two decades, science has increasingly become an integral part of early childhood curricula, and research on teaching and learning science in early years has emerged as an established field of study. Collectively, the findings of a growing body of literature suggest that introducing science in developmentally appropriate ways may support young children’s learning of science concepts and scientific thinking skills. The increasing number of edited volumes and special issues, including this one, devoted to the topic of early childhood science teaching and learning indicates that early science education, as a field of study, will continue to attract researchers from early childhood and science education as well as educational and cognitive psychology.

Machine Learning in Human Emotion Detection from the Speech

The identification of speech emotions is amongst the most strenuous and fascinating fields of machine learning science. In this article, Chinese emotions are classified as a disruptive atmosphere that classifies several feelings into four major emotional organizations: pleasure, sorrow, resentment, and neutrality. A machine learning in human emotion detection (ML-HED) framework is proposed. The technology suggested removing prosodic and spectrum elements of an audio wave, such as a pulse, power, amplitude, Cepstrum melt frequency correlations, linearly fixed Cepstral, and identification with a template. In all, 87,75% of performers’ statements and 93% of women’s actors were given reliability. The research findings show that the revolutionary technology achieves greater precision by accurately interpreting the feelings, which contrasts with current speech emotion recognition approaches. Besides, the derived characteristics were contrasting with various classification techniques in this study for the comprehensive idea.

PENINGKATAN PRESTASI BELAJAR IPA FISIKA DENGAN MENERAPKAN PEMBELAJARAN TUNTAS (MASTERY LEARNING) KELAS XI-TKJ SMK NEGERI 1 NARMADA KABUPATEN LOMBOK BARAT TAHUN PELAJARAN 2019-2020

ABSTRAKPrestasi belajar adalah hasil atau akibat dari kegiatan belajar.Untuk mengetahui tentang prestasi belajar perlu dijelaskan tentang hakekat belajar.Belajar merupakan suatu proses yang dilakukan seseorang untuk memperoleh suatu perubahan tingkah laku yang baru secara keseluruhan,sebagai hasil pengalaman ( Slameto,1991).Dimana perubahan itu bersifat kontinyu dan fungsional,terjadi secara sadar,bersifat positif dan aktif,bukan bersifat sementara,bertujuan atau terarah,dan mencakup seluruh aspek tingkah laku yang selanjutnya dinamakan prestasi belajar. Prestasi belajar dapatdikatakan membekas atau konstan, jika perubahan yang terjadi akibatproses belajar tahan lama dan tidak terhapus begitu saja.Proses pembelajaran khususnya IPA Fisika akan lebih efektifdan bermakna apabila siswa berpartisi aktif, dengan cara tidakmenunjukkan sikap pasif di dalam kelas maupun di luar kelas. Tetapisampai saat ini masih banyak terdengar keluhan bahwa mata pelajaranIPA Fisika membosankan, tidak menarik, memusingkan yang cenderungmembuat siswa menjadi kurang merespon saat pelajaran berlangsung,bahkan ada siswa yang tidak masuk sekolah dikarenakan ada matapelajaran IPA Fisika . Kenyataan ini adalah suatu persepsi negatif terhadap IPA Fisika.Salah satu cara untuk meningkatkan prestasi belajar siswa dalam pembelajaran IPA Fisika adalah melalui pendekatan belajar tuntas (masterylearning).Oleh karena itu penulis perlu melakukan penelitian tindakan kelas dengan judul Peningkatan Prestasi Belajar IPA Fisika dengan Menerapkan Pembelajaran Tuntas(Mastery Learning ) Kelas XI-TKJ SMK Negeri 1 Narmada Kab. Lombok Barat Tahun Pelajaran 2019-2020. Kata Kunci: pembelajaran tuntas; mastery learning; prestasi belajar. ABSTRACTLearning achievement is the result or result of learning activities. To know about learning achievement, it is necessary to explain about the nature of learning. Learning is a process carried out by a person to obtain a new behavior change as a whole, as a result of experience (Slameto, 1991). Where the changes are continuous and functional, occur consciously, are positive and active, not temporary, purposeful or directed, and cover all aspects of behavior, hereinafter referred to as learning achievement. Learning achievement can be said to be imprinted or constant, if the changes that occur as a result of the learning process are durable and not simply erased. The learning process, especially Physics Science, will be more effective and meaningful if students participate actively, by not showing a passive attitude in the classroom or outside the classroom. But until now, there are still many complaints that Physics Science subjects are boring, uninteresting, confusing which tends to make students less responsive during lessons, there are even students who don't go to school because there are Physics Science subjects. This fact is a negative perception of Science Physics. One way to improve student achievement in learning science physics is through a mastery learning approach. Therefore, the authors need to conduct classroom action research with the title Improving Physics Science Learning Achievement by Applying Mastery Learning for Class XI-TKJ SMK Negeri 1 Narmada Academic2019-2020 Year. Keywords: complete learning; mastery learning; learning achievement.

PENINGKATAN PRESTASI BELAJAR IPA FISIKA DENGAN MENGGUNAKAN PENDEKATAN PROBLEM POSSING DENGAN LATAR PEMBELAJARAN KOOPERATIF KELAS XI-ADM.A SMK NEGERI 1 NARMADA KABUPATEN LOMBOK BARAT TAHUN PELAJARAN 2016-2017

ABSTRAKMayoritas guru IPA Fisika saat ini masih menggunakan cara-cara konvensional dalam pembelajaran IPA Fisika. Pendekatan pembelajaran ini dilakukan dengan metode ceramah dan tanya jawab. Kelebihan dan pendekatan ini adalah dapat mengajarkan materi yang relatif banyak dalam waktu yang singkat, tetapi pembelajaran ini memperlakukan siswa hanya sebagai objek sehingga siswa cenderung pasif dan hanya menerima pengetahuan dari gurunya saja. Pembelajaran konvensional hanya menyajikan materi IPA Fisika secara tekstual sehingga siswa kesulitan menerapkannya dalam kehidupan sehari-hari.Untuk meningkatkan kualitas pembelajaran IPA Fisika dibutuhkan pembelajaran yang merangsang siswa untuk melakukan pengamatan, penyelidikan serta mengolah informasi sehingga pada akhirnya siswa dapat memahami konsep secara bermakna. Pembelajaran yang menekankan keaktifan siswa dan berpusat pada siswa merupakan salah satu upaya yang dapat dilakukan untuk memperbaiki kualitas pembelajaran IPA Fisika.Salah satu proses pembelajaran yang sesuai adalah pembelajaran Cooperative Learning.Oleh karena itu penulis perlumelakukan penelitian tindakan dengan judul Peningkatan Prestasi Belajar IPA Fisika dengan Menerapkan Model Pembelajaran Cooperative Learning Kelas XI TKR SMK Negeri 1 Narmada Kab.Lombok Barat Tahun Pelajaran 2016-2017 Kata kunci: problem possing; cooperative learning; prestasi belajar. ABSTRACTThe majority of Physics Science teachers currently still use conventional methods in learning Science Physics. This learning approach is carried out using lecture and question and answer methods. The advantage of this approach is that it can teach relatively a lot of material in a short time, but this learning treats students only as objects so that students tend to be passive and only receive knowledge from the teacher. Conventional learning only presents physics science material textually so that students have difficulty applying it in everyday life. To improve the quality of science learning physics requires learning that stimulates students to observe, investigate and process information so that in the end students can understand concepts meaningfully. Learning that emphasizes student activity and is student-centered is one of the efforts that can be made to improve the quality of learning science physics. One of the appropriate learning processes is cooperative learning. Therefore, the authors need to conduct action research with the title Improving Physics Science Learning Achievement by Applying Cooperative Learning Model Class XI TKR SMK Negeri 1 Narmada Kab. Lombok Barat 2016-2017 Academic Year Keywords: problem possing; cooperative learning; prestasi belajar.

ABSTRAKBelajar merupakan suatu kegiatan kreatif. Belajar bukan berarti hanya menyerap tetapi juga mengkonstruk pengetahuan. Belajar IPA Fisika akan optimal jika siswa terlibat secara aktif dalam membuat, bukan hanya strategi penyelesaian, tetapi juga masalah yang membutuhkan strategi tersebut.Menurut Upu ( 2003:10 ) Problem Possing dapat dilakukan secara individu atau kalsikal ( classical ), berpasangan ( in pairs ), atau secara berkelompok( groups ). Masalah atau soal yang diajukan oleh siswa secara individu tidak memuat intervensi dari siswa ini. hal ini dapat mengakibatkan soal kurang berkembang atau kandungan informasinya kurang lengkap. Soal yang diajukan secara berpasangan dapat lebih berbobot dibanding soal yang diajukan secara individu, dengan syarat terjadi kolaborasi di antara kedua siswa yang berpasangan tersebut. Jika soal dirumuskan oleh suatu kelompok kecil ( tim ), maka kualitasnya akan lebih baik dari aspek tingkat keterselesaian maupun kandungan informasinya. Kerjasama diantara siswa dapat memacu kreativitas serta saling melengkapi kekurangan mereka.Pada pembelajaran kooperatif, siswa dibagi kedalam kelompok-kelompok kecil yang heterogen. Mereka akan bekerja sebagai sebuah tim untuk memahami materi pelajaran dan meyelesaikan tugas yang diberikan. Oleh karena itu penulis perlu melakukan penelitian tindakan kelas dengan judul Peningkatkan Prestasi Belajar IPA Fisika dengan Menggunakan Pendekatan Problem Possing dengan Latar Pembelajaran Kooperatif Kelas XI-ADM.A SMK Negeri 1 NarmadaTahun Pelajaran 2017-2018. Kata Kunci: problem possing; cooperative learning; prestasi belajar. ABSTRACTLearning is a creative activity. Learning does not mean only absorbing but also constructing knowledge. Learning Science Physics will be optimal if students are actively involved in making, not only solving strategies, but also problems that require these strategies. According to Upu (2003:10) Problem Possing can be done individually or classically (classical), in pairs (in pairs), or in groups (groups). Problems or questions posed by students individually do not contain intervention from these students. this can result in less developed questions or incomplete information content. Questions posed in pairs can be more weighty than questions posed individually, provided that there is collaboration between the two students in pairs. If the questions are formulated by a small group (team), then the quality will be better in terms of the level of completion and information content. Cooperation among students can stimulate creativity and complement each other's shortcomings. In cooperative learning, students are divided into small, heterogeneous groups. They will work as a team to understand the subject matter and complete the assigned tasks. Therefore, the authors need to conduct classroom action research with the title Improving Physics Science Learning Achievement by Using a Problem Possing Approach with a Cooperative Learning Background for Class XI-ADM.A SMK Negeri 1 Narmada for the 2017-2018 academic year. Keywords: problem possing; cooperative learning; learning achievement.
