Learning English

One of the keys to the success of learning English is the growth of students' willingness to actively speak in order to implement the theory they have learned. As is usually a skill, if you don't get used to it, it will definitely feel heavy and difficult. That's what happened to class XII DPIB 2 students, where on average they were reluctant to speak, either asking or answering the teacher's questions. They are passive, and mostly silent. There are many things behind their fear such as fear of being wrong, fear of shame, and lack of confidence due to lack of vocabulary and speaking practice. This study aims to increase students' willingness to implement learning using Self Video Recording (SVR) to increase students' willingness to speak and what aspects are most influenced by SVR. This research was conducted at SMK Negeri 2 Bandar Lampung for two months, namely January and February 2019 for class XI students majoring in Information and Building Modeling Design (DPIB). The author uses a one-group pretest-posttest design, where students are presented with questions on a questionnaire about willingness to communicate. The questionnaire contains 25 questions that are able to reveal in what situations they want to communicate in English class. To achieve the goal, the writer did 1x pretest, 3x treatment, and 1x posttest. After comparing the results of the pretest and posttest, the test hypothesis which states that the implementation of learning using self video recording can show a significant difference before and after the implementation of learning as long as the T-value > T-table with a significant level below 0.05. ABSTRAKSalah satu kunci keberhasilan pembelajaran Bahasa Inggris adalah tumbuhnya kemauan siswa untuk aktif berbicara guna mengimplementasikan teori yang telah mereka dapatkan. Sebagaimana lazimnya sebuah keahlian, jika tanpa dibiasakan pasti akan terasa berat dan sulit. Begitulah yang terjadi pada siswa kelas XII DPIB 2, dimana rata-rata mereka enggan berbicara, baik bertanya ataupun menjawab pertanyaan guru. Mereka pasif, dan lebih banyak diam. Ada banyak hal yang melatarbelakangi ketakutan mereka seperti takut salah, takut malu, dan tidak punya kepercayaan diri karena minimnya kosa kata dan latihan bicara. Pada penelitian ini bertujuan untuk meningkatkan kemauan siswa dengan implementasi pembelajaran menggunakan Self Video Recording (SVR) dapat meningkatkan kemauan siswa dalam berbicara dan aspek apakah yang paling banyak dipengaruhi oleh SVR. Penelitian ini dilaksanakan di SMK Negeri 2 Bandar Lampung selama dua bulan, yaitu Januari dan Februari 2019 pada siswa kelas XI jurusan Desain Pemodelan Informasi dan Bangunan (DPIB). Penulis menggunakan desain one-group pretest-posttest, dimana para siswa disajikan pertanyaan-pertanyaan pada sebuah kusioner tentang kemauan berkomunikasi (willingness to communicate). Kuesionaer tersebut berisi 25 pertanyaan yang mampu mengungkap pada situasi seperti apa mereka mau berkomunikasi pada kelas Bahasa Inggris. Untuk mencapai tujuan, penulis melakukan 1x pretest, 3 x perlakuan, dan 1x posttest. Setelah membandingkan hasil pretest dan posttest, maka hipotesa tes yang menyatakan bahwa implementasi pembelajaran menggunakan self video recording dapat menunjukkan perbedaan yang signifikan sebelum dan sesudah pelaksanaan pembelajaran selama T-value > T-table dengan tingkat signifikan dibawah 0,05.

English Literacy

English literacy education plays a key role in establishing literate societies in the 21st century. Having teachers and librarians as professional educators and educational personnel working together, with the provision of relevant literacy facilities, helps achieve this goal. This study applies the Partnership with Librarians Strategy (PLS) by using an equivalent time-samples design to promote students’ English literacy skills. Forty-five seventh, eighth, and ninth graders were randomly selected as the population for this study. Their literacy achievements were measured by using listening, reading, writing, and speaking tests before and after the teaching and learning process. The students’ learning was also monitored using formative tests during the intervention. The results showed that the students’ English skills improved significantly. The improvement is hypothesised to be influenced by the use of PLS as it is also statistically proven by the contribution of each literacy skill to students’ English literacy total achievement, i.e., reading (63.6%), writing (22.9%), speaking (9.2%), and listening (4.3%). It is concluded that PLS makes a significant difference in English literacy learning and therefore deserves to be implemented in any English class coupled with an assessment strategy based on further classroom research to determine its potential effect.

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.

The actor/observer effect was examined by Storms in a 1973 study which manipulated perceptual orientation using video recordings. Storms' study was complex and some of his results equivocal. The present study attempted to recreate the perceptual reorientation effect using a simplified experimental design and an initial difference between actors and observers which was the reverse of the original effect. Female undergraduates performed a motor co-ordination task as actors while watched by observers. Each person made attributions for the actor's behaviour before and after watching a video recording of the performance. For a control group the video recording was of an unrelated variety show excerpt. Actors' initial attributions were less situational than observers'. Both actors and observers became more situational after the video replay but this effect occurred in both experimental and control groups. It was suggested the passage of time between first and second recording of attributions could account for the findings and care should be taken when interpreting Storms' (1973) study and others which did not adequately control for temporal effects.

This study evaluated the effectiveness of a microcurrent toothbrush (approved by the US Food and Drug Administration [FDA]), which employs a superimposed alternating and direct electric current, named as a Proxywave® technology, similar to the intensity of the biocurrent, in plaque removal and reducing gingivitis by biofilm removal through the bioelectric effect. This study enrolled 40 volunteers with gingivitis. Dental observations were made every two weeks, before and after the use of each toothbrush. We randomly assigned participants into two groups: one group used the Proxywave® toothbrush (PB) for two weeks followed by the control toothbrush (CB) for two weeks, while the other group used the CB for two weeks followed by the PB. The participants had a two-week washout period. If the toothbrush used earlier has had an effect on the bacterial flora in the oral cavity, this is to remove this effect and return it to its previous state. During each dental visit, we recorded plaque index (PI) and gingival index (GI) scores. The PI and GI scores were significantly lower in both the PB and the CB (p < 0.05). Considering the PI, there was no significant difference between the toothbrushes on all the surfaces. Considering the GI, the PB showed a significant decrease in the interproximal surface, compared to the CB (p < 0.05). The PB showed a significant decrease in the interproximal GI and had a beneficial effect in the interproximal area where the bristles could not reach. No adverse events were observed in the participants during the clinical trial. The microcurrent toothbrush is a device that can be safely used for plaque removal.
