Năm bảo vệ: 2011 Abstract: Recently, vocabulary has been a prominent concern of many applied linguistic
theorists and researchers in the field of teaching and learning English. When it comes to
studying vocabulary, the greatest challenge is likely retaining the words. Researchers and
teachers now have been drawn to the concern of how to make students enhance
vocabulary retention for communicative value. This minor thesis investigates the impact
of application a wide range of repetitive and recycling-focused activities on 11th grade
students‟ retention in Long Hai – Phuoc Tinh high school. This study was conducted by
quasi-experimental method with 84 participants in the two randomly assigned groups.
The experiment lasted for 6 weeks, during which the students were led through the
reading, speaking, listening, writing and language focus in a normal way. The students in
the experimental group, however, were involved in a variety of additionally cooperative
activities in lessons while there no vocabulary focused activities were employed in the
control group. The data were collected by means of T-test, questionnaires and
observation. The results showed that the repetition and recycling worked on the
experimental group and the experimental group also gave positive feedback on the
treatment. For better application, however, more attention should be paid to the class size,
students‟ level of proficiency and their preferred techniques of memorizing words. In
addition, the study suggests pedagogical implications and recommendations for further
studies.

years makes me designate them. A wide range of designed activities were carried out (mostly at
the beginning of the classes) when teaching two classes named 11A3 and 11A5 at Long Hai –
Phuoc tinh high school. And the results supported my hypothesis that teachers can create
repetitive and recycling-focused activities to help students improve their vocabulary retention.
2. Aims of the study
The study aims at proving that repetitive and recycling focused activities can help 11
th
grade
students to retain words better. These students are non-English major ones and have three classes
of English a week. There exists a fact that they cannot retrieve the words which they have learnt
in previous lessons for communication when needed. In other words, they soon forget words they
have just acquired. The main aim of this study therefore is to investigate the impact of repetition
and recycling on vocabulary learning and retention, or to put it differently, the extent to which
short tailored activities helps to retain vocabulary for the students at Long Hai – Phuoc Tinh
High school and provide some pedagogical implications.
3. Scope of the study
There are enormous activities as tools of enhancing vocabulary retention available on the
internet that you can approach with a mouse click. Most of them are easy to be applied and
tested. In the current study, I set the limit of investigating possibly – applied activities that can be
carried out at beginning or in the middle of 45-minute periods in such large-sized classes at Long
Hai – Phuoc Tinh High school, vung Tau. The activities were related to first three units (which
equal to 18 lessons) of the course book English 11 introduced by Educational Press only because
with the timeframe of 6 weeks it is supposed to be infeasible to conduct a research study on a
larger scale which can produce very convincing results.
4. Research hypotheses and questions
In order to achieve the above purposes, the study was designed to test the following hypotheses:
 Null hypothesis: The students who take part in the experiment get the same
result measured in the post-test and have the same improvement in their vocabulary retention as
those who do not.
 Alternative hypothesis: Students who frequently deal with repetitive and

Part B is the development which consists of three chapters. Chapter one reviews scholarly
theoretical background to teaching and learning vocabulary in a second language including
factors which affect vocabulary acquisition process. This chapter also reviews some meaningful
activities which are initiated by different researchers. Chapter two deals with the methodology of
this research in terms of the setting of the study, sampling participants, instruments and
procedure of data collection. Chapter three devotes to the account of the study in terms of data
analysis and findings interpreted from the results of the T-test and questionnaires.
Part C is the conclusion which discusses the major findings and limitations of the research, then
suggests teaching implications and proposes some suggestions for further research.
