A wise man said that “you will never be a pious when you never feel loneliness”, because loneliness can be used as an indicator of someone’s level of piety. In loneliness, the awareness of God’s existence can be felt, because in loneliness a person will not be affected by motives that come from the encouragement or motivation of the other persons’ prensence. Meanwhile someone’s piety which is shown in the public, according to the author it is very difficult to assess the real of sincerity. There are thousands motives when someone do observance in the middle of the social communities. This research used a qualitative research method with phenomenological research tradition, in the terms of Lindlof (1995:27) it is called as an interpretive paradigm which is refered to the communication research with qualitative methods that perform the tradition of phenomenology, ethnometodology, symbolic interaction, ethnography and cultural studies.

The study attempts to investigate the effect of the treatments of student-student interactions versus teacher-student interactions to the students’ speaking skills in Conversation in English Programs. The number of the students in. each of the three classes (namely student-student interactions class, teacher-student interactions class and control class is not more than 12 students; an ideal number for student-centered class. Each class teacher of the experiment group (student-student interaction group and teacher-student interaction group) is provided with lesson plan and discussions on the lesson plans were conducted prior to the treatments; while the control group teacher has no interfere at all (from the researcher). The students were given situational dialog test before being treated. After being treated for ten consecutive sessions, the same test was administered again. To meet the prerequisite for normal distribution, the data of pre test and post test were analyzed. After normal distribution test was conducted, to determine the progress from the pretest andposttest, paired samples t-test is used; while comparing the progress of the students’ speaking skills in those three groups, one way anova is implemented. The results of the gain of the students ‘ achievement was again processed using LSD (Least significant difference) test to further analyze and find out the most significant improvement among the three group. The LSD test showed that the average of students’ achievement in the Student- Student Interactions Group far excelled the achievement of the students in the Teacher-Student Interaction Group and the Control Group. It is clearly seen that the progress of students’ achievement in the Teacher-Student Group did not have a significant difference with the progress of the students in the Control Group. To conclude, student-student interactions, in which students are given exposure to use the language in class around 75%, enhance students speaking skills.

According to Krashen’s affective filter hypothesis, students who are highly motivated
have a strong sense of self, enter a learning context with a low level of anxiety, and are much
more likely to become successful language acquirers than those who do not. Affective factors,
such as motivation, attitude, and anxiety, have a direct impact on foreign language acquisition.
Horwitz et al. (1986) mentioned that many language learners feel anxious when learning foreign
languages. Thus, this study recruits 100 college students to fill out the Foreign Language
Classroom Anxiety Scale (FLCAS) to investigate language learning anxiety. Then, this study
designs and develops an affective tutoring system (ATS) to conduct an empirical study. The
study aims to improve students’ learning interest by recognizing their emotional states during
their learning processes and provide adequate feedback. It is expected to enhance learners’
motivation and interest via affective instructional design and then improve their learning
performance.

Before presenting the notion of vocabulary strategies, it is necessary to know what language learning strategies mean. The term of language learning strategies has been associated with the four basic skills such as, listening, speaking, reading, and writing.lt also deals with other skill areas as well. For example, there are strategies associated with vocabulary and translation. But what are actually language learning strategies?

In this paper, we describe a prototype of web-based intelligent handwriting education
system for autonomous learning of Bengali characters. Bengali language is used by more than
211 million people of India and Bangladesh. Due to the socio-economical limitation, all of the
population does not have the chance to go to school. This research project was aimed to develop
an intelligent Bengali handwriting education system. As an intelligent tutor, the system can
automatically check the handwriting errors, such as stroke production errors, stroke sequence
errors, stroke relationship errors and immediately provide a feedback to the students to correct
themselves. Our proposed system can be accessed from smartphone or iPhone that allows
students to do practice their Bengali handwriting at anytime and anywhere. Bengali is a
multi-stroke input characters with extremely long cursive shaped where it has stroke order
variability and stroke direction variability. Due to this structural limitation, recognition speed is
a crucial issue to apply traditional online handwriting recognition algorithm for Bengali
language learning. In this work, we have adopted hierarchical recognition approach to improve
the recognition speed that makes our system adaptable for web-based language learning. We
applied writing speed free recognition methodology together with hierarchical recognition
algorithm. It ensured the learning of all aged population, especially for children and older
national. The experimental results showed that our proposed hierarchical recognition algorithm
can provide higher accuracy than traditional multi-stroke recognition algorithm with more
writing variability.
