Digital Language Lab
Digital Language Lab

For a student, developing a dynamic personality is the key to survive and succeed in today’s competitive world. Perfect interpersonal skill developed through accurate pronunciation and fluent presentation of a language is one of the major options to become dynamic. Though our mother tongue is Bangla, many of us cannot speak it nicely. A student might be academically sound, but if he cannot communicate smartly, crossing hurdles of job interviews becomes impossible. Irrespective of professions, gaining skill in additional languages is essential in today’s global village where communication is the sole option to survive. Considering this fact, Hasib Dream School College has set up an advanced language learning lab where students can develop their skills in different languages, including Bangla, English and Arabic. A Few top educational institutions in the country own such labs.


The lab is operated by the world-renowned Sanako software. The objective of this advanced lab is to regularly train students to develop their four basic language skills–listening, speaking, reading and writing. Here, the students learn how to correctly pronounce and converse using advanced equipment, including a computer, smart board, document camera, and sound system. Students learn languages from trained and skilled teachers who teach them according to well developed syllabus prepared for each class.


The fully air-conditioned lab provides each student with a separate computer desk. During the lab class, teachers can inspect the students’ computers right from the dais by using Sanako Software and solve their problems whenever necessary. After learning, students can record their voices and listen to it themselves. The teachers then listen to them and correct them, and through these repeating practices, students finally grasp it comprehensively. Equipped with advanced technologies, this exceptional lab is being considered one of the groundbreaking steps taken by Hasib Dream School College.
