Tujuan penelitian ini adalah untuk meningkatkan kualitas pembelajaran biologi ditinjau dari aspek performance guru dalam kelas, iklim kelas, sikap ilmiah, dan motivasi belajar pada siswa kelas X9 SMA Negeri 5 Surakarta tahun pelajaran 2011/ 2012. Penelitian ini merupakan penelitian tindakan kelas yang berlangsung dalam 3 siklus. Tiap siklus terdiri atas 4 tahapan dasar yaitu perencanaan, tindakan, observasi, dan refleksi. Pengumpulan data penelitian menggunakan angket, lembar observasi, dan wawancara. Validitas data diukur dengan menggunakan teknik triangulasi yaitu triangulasi metode dan triangulasi observer. Teknik analisis data menggunakan teknik analisis deskriptif. Hasil penelitian ini menunjukkan bahwa berdasarkan lembar observasi rata-rata prosentase capaian performance guru dalam kelas pada siklus I sebesar 83,33%, 96,67% pada siklus II, dan 96,67% pada siklus III. Iklim kelas pada siklus I sebesar 77,34%, 94,53 pada siklus II, dan 96,87 pada siklus III. Sikap ilmiah pada siklus I sebesar 61,72%, 72,66% pada siklus II, dan 81,25 pada siklus III. Motivasi belajar pada siklus I sebesar 73,44%, 88,28% pada siklus II, dan 86,72% pada siklus III. Sementara berdasarkan angket, rata-rata prosentase capaian indikator iklim kelas pada siklus I sebesar 82,62%, 83,54% pada silus II, 81,25% pada siklus III. Sikap ilmiah pada siklus I sebesar 75,66%, 74,71% pada siklus II, dan 74,95% pada siklus III. Motivasi belajar pada siklus I sebesar 78,49%, 78,64 pada siklus II, 77,45% pada siklus III. Hasil wawancara siswa dapat disimpulkan bahwa interaksi antarsiswa dan siswa dengan guru meningkat dan menjadikan iklim kelas menjadi lebih kondusif saat pelaksanaan tindakan. Sikap ilmiah terbentuk melalui kegiatan penyelidikan dan diskusi kelompok dalam memecahkan masalah. Siswa juga termotivasi untuk belajar dengan pembelajaran berdasarkan masalah, minat terhadap masalah meningkat, siswa juga merasa pembelajaran selam tindakan merupakan kegiatan yang menarik. Kesimpulan dari penelitian ini adalah penerapan model pembelajaran Problem Based Instruction (PBI) dapat meningkatkan kualitas pembelajaran biologi ditinjau dari aspek performance guru dalam kelas, iklim kelas, sikap ilmiah, dan motivasi belajar pada siswa kelas X9 SMA Negeri 5 Surakarta tahun pelajaran 2011 / 2012 This research aims to improve learning quality of biology considered by teacher performance in the class, classroom climate, scientific attitude, and learning motivation of student in class X9 SMA 5 Negeri Surakarta in academic year 2011/2012 This research was a classroom action research and performed in 3 cycles, every cycle consists of 4 step, namely planning, action, observation, and reflection. The data was collected in four method, namely quetionnaire, observation, and interview. Tha data was validated by triangulation method and triangulation observer. The analyzed teknic used descriptive. The result of this research showed that according observation sheet the average precentage of teacher performance had been improved from 83,33% in cycle I, to 96,67% in cycle II and ended up by 96,67% in cycle III. The classroom climate had been improved from 77,34% in cycle I, to 94,53% in cycle II and ended up by 96,87% in cycle III.
