Check for Understanding
By using cooperative learning model: Number Head Together (NHT)
Step 1: Create group
ü  Teacher divides students into 9 groups based on absence order. The first 7 groups contain 5 students while the last 2 groups contain 4 students. 
ü  Teacher asks students to name their groups with one of city name in Indonesia
ü  Teacher asks students to give number (1-5) to each student in their group randomly
Step 2: Conduct material
ü  Teacher explains the definition of intersection, union and difference of two set which showed at PPT and written at whiteboard by the teacher
ü  Teacher asks every student in a group to retell the definition of intersection, union and difference of two sets to a friend at their right side
ü  Teacher explains one example of intersection, union, and difference of two set and how to dram it in Venn diagram
ü  Teacher asks students to find another example about intersection, union and difference of two sets and write it in their note book
ü  Teacher lets the students to asks about the part that they still confused

43 small pieces of paper contains number 1-5

Step 3: Group discussion
ü  Teacher gives student’s worksheet which contains 5 problems about intersection, union, and difference of two set to the students
ü  The teacher asks students to discuss about the problems and try to answer the problems
Step 4: Giving Answer
ü  Teacher mention a number randomly to answer the 1st question
ü  Teacher asks every student who has the same number mentioned by teacher to raised their hand
ü  Teacher asks every students who raise their hand to writes their answer in the whiteboard
ü  Teacher confirm the students answer and concludes the right answer of the 1st number
ü  Teacher repeat steps 4 until all the numbers of question are answered.

Cerpen Keluarga

  Dari Putri Untuk Ayahnya yang Hilang Aku tak mungkin ada tanpa ayah, tapi aku bisa hidup tanpa ayah, meskipun aku tidak benar-benar hidup. Jiwa dan semangatku terkubur bersama dengan hilangnya sosok ayah dalam hidupku. Memang sudah lama sekali, bahkan sebelum aku bisa mengatakan kepedihan dalam hatiku. Ayahku adalah sosok seorang pemimpin yang mampu membuat keputusan besar, itulah sebabnya ia meninggalkanku. Ayahku adalah sosok yang berani, sehingga tanpa berpikir panjang ia pergi. Ayahku adalah sosok yang kuat, itulah sebabnya ia mampu hidup tanpaku. Tapi sayang, kurasa ia telah mati rasa. Ia tak lebih dari sebuah robot tangguh. Bisa melakukan segala sesuatu dengan sempurna, tapi tak dapat mengerti dirinya. Ia tak bisa jatuh cinta dan tak bisa menangis, tak bisa pula merindu. Apa yang akan kukatakan ketika kekasih jiwaku bertanya dimana ayahku? Haruskah kujawab di rumah? Rumah keluarga kita yang selalu ada dalam mimpiku, tapi itu tak nyata. Haruskah kujawab dijalan?

Learning Method: Concept Map

Concept Mapping as a Learning Strategy 1.       The Nature of Concept Mapping Concept mapping is one strategy or model of learning that is often used to discuss specific material that is relational. This learning strategy is very helpful for students to understand a concept and the relationship of the concept with the part or sub topic that is in it. According to Novak (1984), "Concept maps are intended to represent meaningful relationships between concepts in the form of propositions". This proposition is two or more concepts associated with the line labeled (conjunction) that has a meaning. This is what forms the concept map. Concept map is derived from a concept that is the center or core of a material that has a close relationship with the other parts that can be derived from the core concept. Concept map is formed from a combination of materials that are interconnected. Concept map can facilitate students to understand more quickly about the relatio...

Nenek Rohaya (Kritik Sosial berlatar budaya Batak)

Nenek Rohaya (karya: Lentaria Lumban Toruan) Hari minggu kali ini, penduduk Sianjur Mulamula gempar oleh kunjungan Pak Tamba ke gereja HKBP resort Limbong Sagala. Biasanya hanya beberapa jemaat saja yang menghadiri ibadah, itupun hanya ibu-ibu yang akan membaptiskan bayinya atau anak sekolah yang harus meminta bukti mengikuti kebaktian sebagai tugasnya di sekolah. Tapi kali ini karena pengkhotbah adalah Pak Tamba, calon anggota DPR yang kekayaannya tersiar di seluruh desa, maka seluruh kursi gereja penuh bahkan beberapa kursi sengaja dipinjam dari warung samping gereja. Memang beginilah keadaanya sekarang, semakin tinggi jabatan seseorang maka semakin kuatlah daya tariknya. Jika pendeta Haposan yang berkhotbah, tidak ada jemaat yang mendengarkan, dia dianggap seperti radio yang menyiarkan berita zaman purbakala yang tidak menarik sama sekali. Ibu-ibu biasanya keluar untuk menyusui bayinya, sementara anak-anak sekolah sibuk dengan HP buatan China yang kameranya buram dan ukuranny...
