Pandemi Covid-19 telah mendisrupsi dunia pendidikan yang mengakibatkan terjadinya migrasi pembelajaran luring menjadi daring. Situasi ini menjadikan tantangan tersendiri bagi pembelajaran Pendidikan Jasmani Olahraga dan Kesehatan (PJOK). Penelitian ini bertujuan untuk mengkaji kondisi pembelajaran daring pendidikan jasmani dan kebutuhan guru terhadap modul elektronik berbasis model pembelajaran Personalized System of Instructions (PSI) pada pembelajaran daring pendidikan jasmani. Penelitian ini menggunakan metode survei. Pengumpulan data dilakukan dengan menggunakan kuesioner elektronik via Google Form yang dibagikan kepada guru-guru anggota Musyawarah Guru Mata Pelajaran (MGMP) PJOK Sekolah Menengah Pertama (SMP) Kabupaten Klaten sebagai responden. Sebanyak 61 responden menjawab dan mengisi kuesioner secara lengkap antara tanggal 7-14 Oktober 2021. Hasil survei menunjukkan tiga temuan yaitu: (1) Kondisi pembelajaran daring pendidikan jasmani belum efektif di masa pandemi Covid-19. Guru mengalami kendala dalam melaksanakan pembelajaran pendidikan jasmani secara daring. (2) Dibutuhkan e-modul sebagai bahan pembelajaran untuk siswa secara mandiri di rumah. (3) Dibutuhkan penerapan model pembelajaran Personalized System of Instructions (PSI) dalam pembelajaran daring pendidikan jasmani. Model pembelajaran PSI diyakini tepat dan efektif sebagai model pembelajaran mandiri.
