The ability to speak in English is one of the requisite skills for vocational high school students majoring in hospitality training. However, most tenth-grade students manifested insufficient skills in speaking English, which resulted in low confidence in speaking. To cope with the challenge, the researchers implemented modified role-play and guided writing to stimulate students in speaking English in classroom action research. The procedure of the research consisted of planning, acting, observing and reflecting. The researchers employed observation, questionnaire, documentation and field notes in collecting the data. The research findings presented that the students’ motivation to practice their speaking had increased significantly. Thus, the researchers conclude that role-play and guided writing can be used as a communicative activity where students can simultaneously practise and improve their proficiency in communicating. The researchers also propose suggestion to fellow English teachers to effectively manage the time as well as engaging media to create an enjoyable atmosphere in the teaching-learning process through role-play and guided writing.

Abstract Implementation of demonstration method in the teaching of chemistry is assigned as the right strategy to improve students’ achievement as it is proved that the method can bring an abstract concept to reality in the class. The study is conducted to vocational high school students in SMKN1 Pargetteng getteng Sengkut Pakfak Barat at accademic year 2013. The teaching has been carried out three cycles on the teaching of chemistry topic of colloid system. In the study, the class is divided into two class, experiment class and control class. The demontration method is used to teach students in experimental class while the teaching in control class is conducted with lecture method. Both are evaluated by using multiple choise tests before and after the teaching procedures, and the ability of students to answer the problems are assigned as students’ achievements. The results showed that demonstration method improved students’ achievement in chemistry. The students in experimental class who are taughed with demonstration method (M=19.08±0.74) have higher achievements compare with control class (M=12.91±2.52), and both are significantly different (tcalculation 22.85 > ttable 1.66). The effectivity of demostration method in experimental class (97%) is found higer compare to conventional method in control class (91%).

This study first approaches the history of the observer’s gaze, that is, as observers, we are forming or constructing our way of visualizing moving images. Secondly, it reaffirms the importance and need of resistance of the teaching / learning of Art as a compulsory curricular component for high school. Finally, the third part reports an experience with video art production in a class of first year high school students, establishing an interrelationship between theory and practice, that is, we study video art content to reach the production of videos, aiming as a final result, the art videos created by the students of the Reference Center in Environmental Education Forest School Prof. Eidorfe Moreira High School. The first and second stages of this research share a theoretical part of the Master ‘s thesis, Making films on the Island: audiovisual production as an escape line in Cotijuba, periphery of Belem, completed in 2013.
