AbstrakPenelitian ini bertujuan untuk menyelidiki pengaruh gender siswa terhadap literasi sains melalui pembelajaranproject based learning (PjBL) yang diintegrasikan dengan science, technology, engineering, dan mathematics (STEM) pada tema pencemaran udara. Metode penelitian yang digunakan adalah pre-eksperimen dengan desain The static Group Pretest-Posttest Designyang dilaksanakan di kelas VII SMP Islam Terpadu di kabupaten Sukabumi sebanyak 57 siswa yang terdiri dari kelas laki-laki (29 orang) dan kelas perempuan (28 orang). Pengumpulan data dilakukan dengan menggunakan tes awal dan tes akhir untuk literasi sains dan angket siswa terhadap PjBL STEM. Berdasarkan hasil analisis data diperoleh peningkatan literasi sains siswa kelompok laki-laki dan kelompok perempuan sama-sama mengalami peningkatan dengan rerata N_Gainyaitu 0,36 dan 0,31pada kategori sedang untuk aspek pengetahuan dan kompetensi. Hasil uji-t menunjukkan bahwa peningkatan literasi sainskelas laki-laki dan kelas perempuan berbeda tidak signifikan.Pada aspek sikap sains, kelas perempuan berbeda signifikan dari kelas laki-laki.Tanggapan siswa secara keseluruhan menunjukkan hampir seluruh siswa menyatakan senang dengan pembelajaran PjBL STEM dan memperoleh pengalaman yang sangat berkesan mengikuti tahapan pembelajaran sehingga menimbulkan motivasi dan minat dalam belajar.
Laboratory activities and constructivism are two notions that have been playing significant roles in science education. Despite common beliefs about the importance of laboratory activities, reviews reported inconsistent results about the effectiveness of laboratory activities. Since laboratory activities can be expensive and take more time, there is an effort to introduce virtual laboratory activities. This study aims at exploring the learning environment created by a virtual laboratory and a real laboratory. A quasi experimental study was conducted at two grade ten classes at a state high school in Bandung, Indonesia. Data were collected using a questionnaire called Constructivist Learning Environment Survey (CLES) before and after the laboratory activities. The results show that both types of laboratories can create constructivist learning environments. Each type of laboratory activity, however, may be stronger in improving certain aspects compared to the other. While a virtual laboratory is stronger in improving critical voice and personal relevance, real laboratory activities promote aspects of personal relevance, uncertainty and student negotiation. This study suggests that instead of setting one type of laboratory against the other, lessons and follow up studies should focus on how to combine both types of laboratories to support better learning.
Abstrak Latar Belakang. Angka kejadian stunting di Kecamatan Kalasan pada tahun 2018 sebesar 17,01%, nilai tersebut masih jauh dari target penurunan stunting di Kabupaten Sleman yaitu 10%. Penelitian ini bertujuan untuk mengetahui hubungan antara sanitasi penyediaan air bersih dengan kejadian stunting pada balita di Desa Tamanmartani. Metode. Penelitian ini menggunakan metode analitik dengan pendekatan kasus kontrol. Teknik pengambilan sampel menggunakan total sampling. Sampel penelitian ini adalah ibu yang memiliki balita, yaitu 45 kasus dan 45 kontrol. Instrumen diadaptasi dari formulir inspeksi sanitasi penyediaan air bersih dari Dinas Kesehatan Daerah Istimewa Yogyakarta. Analisis data menggunakan uji Chi-square. Hasil. Hasil penelitian ini menunjukkan ada hubungan signifikan antara sanitasi penyediaan air bersih dengan kejadian stunting (p=0,047, OR=2,705) Penutup. Disarankan bagi masyarakat perlu membersihkan area sekitar sumur gali/ledeng dari kotoran hewan ternak dan sampah, menghindari genangan air serta perbaikan retakan sekitar sumur. Abstract. Background. Stunting incidence at Kalasan District in 2018 was 17.01%, this value is still far from the target for reducing stunting in Sleman Regency, which is 10%. This study aims to determine the relationship between sanitation of clean water supply and the incidence of stunting in children under five in Tamanmartani Village. Method. This study uses an analytical method with a case-kontrol approach. The sampling technique used was total sampling. The sample of this study were mothers who had toddlers aged 0-59 months, there were 45 cases and 45 kontrols. The instrument adapted from the clean water supply sanitation inspection form from Yogyakarta Special Region Health Office. Data analysis using Chi-square test. Results. The results of this study indicate that there is a significant relationship between sanitation of clean water supply and the incidence of stunting (p = 0.047, OR = 2.705). Closing. It is recommended for the community to clean the area around the dug wells from livestock manure and garbage, avoid puddles of water and repair cracks around the well.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
