Pengembangan Powerpoint dengan Discovery Learning Materi Pencemaran Lingkungan Kelas X SMAN 4 Palembang

Abstract

AbstrakBackground: Media pembelajaran merupakan seperangkat alat pendukung yang digunakan oleh guru untuk berkomunikasi dengan siswa. Media dapat membuat siswa aktif selama proses pembelajaran. Salah satu media yang dapat digunakan oleh seorang guru adalah microsoft powerpoint. Proses pembelajaran di dalam kelas guru masih menggunakan media powerpoint yang masih monoton membuat perhatian bisa berkurang dan cenderung pasif terhadap pembelajaran biologi. Untuk menghindari kurang aktifnya siswa dalam pembelajaran, maka diperlukan pengembangan media powerpoint yang dikombinasi dalam model discovery learning. Media powerpoint yang dikembangkan diperlukan penilaian kelayakan agar dapat digunakan dalam proses pembelajaran, terutama pada materi pencemaran lingkungan. Metode: Penelitian pengembangan dilakukan dengan menggunakan model Tessmer, terdiri atas self evaluation dan prototyping (expert reviews, one-to-one, dan small group). Instrumen pengumpulan data yang digunakan berupa lembar observasi, daftar wawancara dan angket. Analisis data penilaian kelayakan mengacu pada Mardapi (2008). Hasil: Hasil penelitian menunjukkan penilaian validator media layak (30), validator materi layak (17), guru sangat layak (28), uji coba one to one cukup layak (27,33), uji coba small group siswa yang belum mempelajari materi layak (33,4), dan uji coba small group siswa yang telah mempelajari materi sangat layak (37,47). Kesimpulan: Media powerpoint yang dikembangkan dengan dikombinasi model discovery learning ini menunjukkan layak digunakan dalam proses pembelajaran. AbstractBackground: Learning media are aids used by teachers to communicate with students. Media can make students active during the learning process. One of the media that can be used by a teacher is Microsoft PowerPoint. The learning process in the classroom teacher still uses powerpoint media that are still monotonous, making attention can be reduced and tends to be passive towards learning biology. To avoid the lack of active students in learning, it is necessary to develop powerpoint media combined in a learning discovery model. Powerpoint media developed need to be made so that they can be used in the learning process, especially in environmental pollution material. Methods: Development research was carried out using the Tessmer model, consisting of self-evaluation and prototyping (expert, one-to-one, and small group reviews). Data collection instruments used consisted of observation sheets, interview lists and questionnaires. Data analysis on the feasibility of meeting in Mardapi (2008). Results: The results of the study prove that the validator of the media is feasible (30), the validator of the material is feasible (17), the teacher is very feasible (28), the trials one to one are quite feasible (27.33), the small group trials of students who do not need decent material (33.4), and a small group trial of students who obtained very decent material (37.47). Conclusion: Powerpoint media developed with a combination of discovery models is feasible to be used in the lea...

Batik module: Health-integrated thematic and its impact on understanding of the concept and behavior of clean and healthy living

“…In addition, this BATIK module is effectively used because the language used is following the first graders of elementary school, where we know that an effective language is a language that is following the development of children. The use of language in media has consistency in words, terms, and sentences that make this media easy to understand during the learning process (Astuti et al, 2019). Color, font size, and the typeface must be made more attractive (Riwu et al, 2019), which will make the developed teaching materials more suitable to use.…”

Efektivitas Model PBL Dan Problem Solving Berbantuan Powerpoint Interaktif Terhadap Kemampuan Berpikir Kritis Peserta Didik Kelas Iv Sd

“…Microsoft Powerpoint merupakan sebuah program presentasi untuk menyampaikan atau menjelaskan ide, laporan dan informasi kepada peserta didik secara audio visual (Astuti et al, 2019). Powerpoint tidak hanya mempermudah guru dalam menyampaikan materi pembelajaran, akan tetapi Powerpoint juga dapat dijadikan sebagai bahan ajar yang bersifat dua arah (interaktif) dimana peserta didik tidak hanya berlaku sebagai pendengar atau pengamat saja namun peserta didik juga ikut terlibat aktif dalam proses pembelajaran (Azura et al, 2019).…”

Development of Electronic Magazine Teaching Materials for Key Determination and Cladograms in Ethnobotany and Phytochemical Studies

“…Nur (2014) explained that magazines can have been covered as an attraction, contain more images/ photos, and have longer actualization value. Astuti et al (2019), explained that images loaded with teaching materials can make it easier for teachers to convey material and make it easier for learners to understand the material during the learning process, especially during online learning that takes place today. Based on data obtained from the Statistik Central Agency in 2019, it is known that smartphone users continue to increase from year to year until reaching 63.53%.…”
