The purpose of this study was to investigate the effects of the Assurance Relevance Interest Assessment Satisfaction (ARIAS) strategies set with Numbered Heads Together (NHT) on students' learning motivation. This quasi experimental study employed a pretest-post test nonequivalent control group design. The population of the research was all the eleventh graders who were enrolled in the science classes of public senior high schools (SMA) in Makassar, Indonesia. There were 21 schools in total. Random sampling technique was used to select 78 participants who were divided into two groups of treatment: 39 students for each treatment. Research instruments were developed based on the Attention, Relevance, Confident, Satisfaction (ARCS) model. Data on students' learning motivation was collected using a questionnaire that was distributed before and after learning. Research data was analyzed using a descriptive statistic and the analysis of covariate (ANCOVA) statistic. The results of the research suggest that learning strategies have an effect on students' motivation. Compared to ARIAS direct learning model, NHT-ARIAS is more potential to improve students' motivation.Keywords: motivation, ARCS, ARIAS, NHT, learning model, assessment, students INTRODUCTIONBiology learning in senior high school (SMA) emphasizes on promoting students' process skills. Therefore, it requires students to get actively engaged in learning. An appropriate learning strategy or learning model could help students improve their motivation in understanding materials and as a result increase their achievement. An important reason why students need to improve their motivation is that because motivation brings a significant impact on learning (Rusillo & Arias, 2004). It is believed that learning could be more meaningful if students are more motivated (Holt, 2010). 124The Effects of Numbered Heads Together-Assurance Relevance … International Journal of Instruction, July 2018 • Vol.11, No.3 Learning motivation plays a major role in determining students' learning outcomes and achievement. Motivation is a process of predicting intensity, direction, and efforts to achieve the goals. According to Tosi, Mero dan Rizzo (2000), motivation has a psychological significance which refers to an individual's internal mental state related to initiation, guidance, persistence, and behavior. Besides, motivation also contains a managerial implications which is associated with an individual's managerial activity to encourage someone to pursue particular objectives. Students' learning motivation can be stimulated by a learning model (Chiang & Lee, 2016). Cooperative learning model has been developed and confirmed as one learning model that can improve students' performance. Cooperative learning is designed to facilitate students' cooperation and dependence on each other in completing a task or purpose. Cooperative learning is aimed to provide students with knowledge, concepts, skills, and understanding (Slavin, 2009). Sadker and Sadker (2005) add that cooperative learni...

One of the important tasks in teaching is assisting students to think. Synectics Model matched with Mind Maps are viewed necessary to be applied in the instruction in order to achieve the target.The research is an experiment research with pre-test posttest control group design. The results of analyses indicate that: (1) there is significance difference with the mean score of creative think ability, creative attitude, and mastery of biology materials due to difference of instruction model used, (2) there is no significant difference of mean score of creative attitude among the students who belong to the high and low achievement. (3) there is no interactional effect between the instructional model used with the students entry behavior towards creative thinking ability, creative attitude, and mastery of biology materials.DUNIA pendidikan dewasa ini dihadapkan pada suatu tantangan yaitu era pengetahuan (knowledge era). Era ini ditandai dengan perkembangan teknologi yang sangat pesat, penuh ketidakpastian, dan dilema. Menurut Handy, sebagaimana dikutip oleh Gibson, era tersebut merupakan era modal intelektual (intellectual capital). 1 Oleh karena itu, tujuan pendidikan dan pengajaran hendaknya bermuara pada pemenuhan keterampilan intelektual siswa agar kelak dapat berasimilasi dengan era pengetahuan. Untuk mewujudkan tujuan tersebut, tampaknya perlu diperhatikan apa yang dikemukakan Raths et. al. bahwa perlu mewujudkan tugas yang terpenting dalam mengajar yaitu membantu siswa berpikir. 2 Salah satu keterampilan intelektual yang perlu diberikan kepada siswa adalah keterampilan mengembangkan daya cipta atau pemikiran kreatif agar ia menjadi individu yang kreatif. 3 Oleh karena itu, hendaknya semua guru mata pelajaran berusaha atau bertujuan untuk mengembangkan kemampuan kreatif siswa sehingga mereka bergerak ke arah "aktualisasi diri" serta kesehatan mental yang lebih baik. 4 Dengan kata lain pemberdayaan siswa agar menjadi kreatif, misalnya dalam hal berpikir LENTERA PENDIDIKAN, EDISI X, NO. 2, DESEMBER 2007 (173−184)

KEYWORDS: model pembelajaran, sains, hasil belajarINOVASI model-model pembelajaran banyak diperbincangkan dalam dunia pembelajaran karena sangat diperlukan, terutama dalam menghasilkan model pembelajaran baru yang dapat memberikan hasil belajar lebih baik, peningkatan efisiensi dan efektivitas pembelajaran menuju pembaharuan. Sering terjadi seorang dosen di perguruan tinggi kurang mempunyai bekal model pembelajaran karena hanya mementingkan penguasaan dan pendalaman materi kuliah serta pengalaman dalam bidang ilmunya, sehingga penyampaian materi kuliah tidak optimum.Pengalaman pembelajaran yang sering dihadapi di perguruan tinggi adalah bahwa banyak mahasiswa menganggap mata kuliah bidang sains sulit dipelajari, sehingga mahasiswa sudah terlebih dahulu merasa kurang mampu untuk mempelajarinya. 1 Hal ini mungkin disebabkan oleh penyajian dosen terhadap materi kuliah yang kurang menarik, membosankan, sulit dan menakutkan sehingga mahasiswa kurang menguasai konsep dasar perkuliahan yang diikutinya, dan akhirnya perkuliahan tersebut menjadi tidak menarik lagi bagi kebanyakan mahasiswa.Beberapa faktor penyebab kurangnya penguasaan materi perkuliahan bagi mahasiswa diantaranya adalah (1) sistematika dan urutan materi kuliah yang belum mampu memotivasi mahasiswa belajar karena * Doktor lulusan Jurusan Pendidikan Biologi pada Program Pascasarjana Universitas Negeri Malang ini adalah dosen Fakultas Tarbiyah dan Keguruan dan Program Pascasarjana UIN Alauddin Makassar.
