Tulisan ini mendiskusikan suatu cara yang paling baik yang dapat dilakukan untuk mengatasi kecemasan matematika, self efficacy dalam membuktikan matematika. Metode yang digunakan adalah tinjauan pustaka. Self efficacy memiliki perananan yang penting dalam menghilangkan kecemasan marematika, dimana jika seseorang memiliki kepercayaan akan kemampuan yang dimilikinya maka akan lebih senang dan giat dalam melakukan pembuktian matematika. Akan tetapi terkadang kebanyakan tidak meyakini atau mempercayai dirinya sendiri sehingga cenderung malas dalam melakukan pembuktian matematika, maka dari itu dibutuhkan learning community dimana mereka mampu berinteraksi dan saling bertukar pikiran sehingga dapat membuka peluang untuk dapat melakukan pembuktian matematika tanpa diiringi kecemasan-kecemasan matematika tersebut.

Salah satu kegunaan penginderaan jauh adalah mengetahui tingkat kerapatan vegetasi menggunakan metode unsupervised classification K- Means dan perhitungan NDVI. Penelitian ini dilakukan di Kecamatan Pangandaran dan menghasilkan peta kerapatan vegetasi. Hasil klasifikasi kerapatan vegetasi di Kecamatan Pangandaran menghasilkan sebanyak 5 klasifikasi yaitu badan air, vegetasi jarang, cukup rapat, rapat, sangat rapat. Peta kerapatan vegetasi tersebut telah dilakukan uji akurasi dan validasi lapangan dengan akurasi sebesar 25% tingkat akurasi dari hasil interpretasi yang diperoleh menunjukan bahwa peta yang dihasilkan belum memenuhi standar USGS untuk dapat digunakan yaitu sebesar 85%.Kata Kunci: Pengindraan Jauh, NDVI, K-Means- Kerapatan Vegetasi, PangandaranABSTRACTRemote sensing is a tool and technique for retrieving spatial data without touching the inte...

The purpose of establishment of open education was to continue six years education program become nine years education program, and to give a chance to elementary school graduated who could not continue their study to regular Junior High School. This study investigated on the techniques of teaching English in the first semester of second year at SMP Terbuka Balen Bojonegoro, included: The techniques that the teacher used both in classroom meeting and in long distance learning, and the students’ responds to the techniques that the teacher used in classroom meeting. This research used descriptive design to obtain the data concerning the research problems. There were three instruments utilized to collect the data; interview, questionnaire, and observation. Based on the research finding; the techniques used by the teacher in teaching English in classroom meeting were both of lecturing and group work. Most of the students liked the combination of lecturing and group work technique that the teacher used in classroom meeting but most of them could not grasp the teacher’s explanation. In fact, the teacher did not teach in long distance learning because the students of SMP Terbuka Balen Bojonegoro had to study at school everyday, from Monday up to Saturday, but the students had their own techniques in long distance learning, they used both of individually and group work techniques. Besides, they also used cassette as their media. Long distance learning also had the advantages and the disadvantages. The advantages were the students could manage their own time of study and they could select their own materials, and the disadvantage was the students felt difficult to ask instructor if they got some difficult.
