frustration of not being able to express oneself
because of a lack of vocabulary. Several
researchers including Laufer and Nationa (2016),
Nation (1991), and Rodríguez and Sadowki
(2008) have recognized the importance of
acquiring vocabulary for the effective use of a
second language and for producing complete
spoken and written texts. In both English as a
second language (ESL) and English as a foreign
language (EFL), vocabulary acquisition is
considered crucial for all language skills,
including listening, speaking, reading, and
writing. Laufer and Nationa (2016) argued that
an adequate vocabulary is essential for successful
second language use because, without it, learners
may not be able to use the structures and
functions they have learned to communicate
effectively. Therefore, it is important for students
to continuously improve their vocabulary skills
and expand their word knowledge. For
vocabulary to be recalled easily, it has gone to
long-term memory (Cowan, 2008).
Vocabulary recall is a process of retrieving words
and their meaning. The process of vocabulary
recall involves encoding new information about
a word in the brain and storing it in memory. In
the storing stage, episodic and semantic memory
are involved; when one of them stores personal
information, another one which is semantic
stores general information. Later to retrieve
vocabulary, the cues are used to trigger recall,
searching the memory for the stored information,
decoding the retrieved information, and
rehearsing the word to consolidate the memory
(Laufer & Nationa, 2016). Different parts of the
brain are involved in each step, including the
auditory and visual cortex, the hippocampus, and
the neocortex. Rehearsal helps to strengthen the
connections between the brain regions involved
in vocabulary recall, improving future recall.
Fansury, & Januarty (2018) mentioned that
semantic and episodic memory have an effective
role in recalling vocabulary. Episodic memories
are associated with specific contextual
information. The sensory experiences and
emotions a student experiences during a lesson
become a part of the memory. These sensory and
emotional cues can be triggered when attempting
to recall the memory, but sometimes the context
is remembered more easily than the actual
information learned. Through context and
emotional cues, the actual information can be
recalled easily. However, to recall vocabulary
easily teachers must incorporate the sensory and
emotional experiences of students to remember
them easily. According to Um et al. (2012),
positive emotions can facilitate learning and
contribute to academic achievement. When
students experience positive emotions, such as
interest, enjoyment, and satisfaction, while
engaging with learning materials, they are more
likely to be motivated to learn and remember the
material.
The Theories That Support Students’
Episodic Memory to Recall Vocabulary
1. Experiential Learning Theory
Experiential Learning Theory (ELT) emphasizes
the central role that experience plays in the
learning process. It provides a holistic model of
the learning process and a multilinear model of
adult development and is based on the works of
Dewey, Lewin, and Piaget. Experiential learning
is the process whereby knowledge is created
through the transformation of experience (Kolb,
1984). ELT differentiates itself from other
learning theories by emphasizing the importance
of subjective experience in the learning process
and by providing a hands-on, participatory
approach to learning that helps students connect
new information to their own experiences.
Affective factors could affect language learners.
For example, motivation and learner autonomy
are two important factors that could affect the
process of learning a language. In language
education, it's important to help students become
independent learners (Yildiz & Yucedal, 2020).
By incorporating students' real-life experiences
into the classroom, ELT can lead to a more
meaningful and relevant learning experience,
improve engagement and motivation, and the
development of important skills such as problem-
solving, critical thinking, and collaboration
(Roberts, 2006). This theory involves four
stages: concrete experience, reflective
observation, abstract conceptualization, and
active experimentation. Concrete experience is
the direct engagement or experience in an event
or activity such as a field trip, or hand on project.
Reflective observation students will reflect and
observe the event. Abstract generalization is
students analyze the information that got from
their experience. The last step is active
experimentation. Students apply the experiment
and the theories that they have learned
throughout the direct experience (Kolb, 1984).
According to Herbet and Burt (2004), episodic
learning is in every sense experiential learning
due to capturing and storing memories in the
form of complete episodes, which include a
connected set of sensory information. This type
of learning is truly experiential, as it has a greater
impact on the student. In addition, the
