PENGGUNAAN ASESMEN KINERJA UNTUK MENGOPTIMALKAN KEMAMPUAN PERSEPTUAL SISWA PADA PELAJARAN BIOLOGI DI SMA NEGERI 1 MALANG

The observation result in learning process and evaluation at SMA Negeri 1 Malang showed that the assessment by biology teacher only usually done in cognitive competence with the test instrument was only daily assignment. So the other competence like affective and psychomotor had not already been done optimally. There was no assessment instrument like rubric or the other instrument.
