usefulness of the GO map instruction to the posttest retelling, and the reason behind

their responses were solicited. Besides, the researcher also interviewed the

participants whose responses to the open-ended questions in the posttest questionnaire

needed to be clarified. The interviews, therefore, served to elicit more detailed

thoughts from the participants toward the GO map instruction.

3.4 Data Analysis

The results of the story retelling performances on the pretest and posttest were

analyzed from five aspects: (1) the story length as indicated by the number of words

contained in the participants’ retelling performances, (2) the fluency in terms of the

original and pruned speech rate, (3) the story element count score and story content

score, (4) the level of the overall retelling performances and (5) the participants’

responses to the GO map instruction. In terms of the calculation of the story length,

the participants’ retold stories were first transcribed. The original word count was

calculated by the number of words in the retelling transcriptions and the pruned word

count was gained with the number of words of false starts and repetitions deducted

from the original word count.

The fluency of the participants’ retelling performances in both the pretest and

posttest was determined by using the original speech rate and the pruned speech rate.

The original speech rate is calculated by dividing the number of words by the total

35

time (words per minute, i.e., “w.p.m.”) (Lennon, 1990). Pruned speech rate, which

is based on Lennon’s (1990) concept of “pruned speech,” is obtained by calculating

speech rate exclusive of false starts and repetitions. The reason for adoption of the

pruned speech rate is that with the false starts and repetitions excluded, the pruned

speech rate substantially reflects the efficient and meaningful content the participants

produce per minute. That is, the pruned speech rate combines speed of speech with

its efficiency in terms of how much repair is required; hence, it serves as an

appropriate measure of fluency.

The story elements in the participants’ retold stories were evaluated in two ways:

the story element count score and story content score. The story element count score

was calculated by how many story element items were included. When an element

was mentioned, a point was awarded. The highest score is seven for there are seven

story elements. The story content score in the participants’ retelling performances

were analyzed and graded according to the grading checklist (see Appendix N). The

scoring criteria on the checklist are adjusted from Morrow (1986). The GO map

checklists (see Appendices E-2 & L-2) for the two retold stories helped provide a

reference for the researcher to judge how many points to assign regarding the story

element content and sequence. The grading checklist were used as criteria for

assigning points to the story elements included and the sequence in which the story

36

elements were organized in their retelling performances. The weight for each story

element varies. For each story element and the sequence, the degree of

completeness and detailedness determines the score the participants got. The

elements on the checklist include “Story Title”, “Setting”, “Characters”,

“Problem/Goal”, “Events”, “End” and “Sequence” with different maximum points,

ranging from the highest 4 to the lowest 0.5. The maximum point is determined by

the proportion of the particular element in stories. Specifically, since the element,

“Events”, comprises the major part of stories, the participants could get as many as

four points if they successfully mentioned eight or more events. “Setting,” including

when and where, has a maximum point of 1.5. For “Characters,” “Problem/Goal,”

“Sequence,” and “End”, the maximum point is 1. As for “Story Title”, since its

proportion is relatively small, its maximum point is 0.5. The primary principle for

assigning points depends on how the participants’ retelling content fitted the

description on the GO map checklist. Specifically, if the retold story content

corresponded with the description of an element, the participants could get the

maximum point. If the content of an element was incomplete or partially wrong,

they could still get some points for the part they recounted correctly. However, if the

content of an element was outright missing or completely twisted, they got no points.

As for “Sequence,” if the participants described the events according to the sequence

37

in which the events take place without making mistakes, a point was rewarded to

them; if there were a few mistakes but the story order was still understandable, they

got 0.5 point. If the participant recalled the story with little or no sequence, they got

no point. The points for each element were accumulated to gain the final score.

The highest total score was ten and the lowest zero. The teacher-researcher and her

colleague, who is also an English teacher, conducted all the ratings for the story

element content and holistic level of the participants’ retellings. They analyzed the

participants’ performances together and settled the differences of their assessment by

discussion. A score was final once they had reached consensus.

The holistic evaluation of the participants’ performances was carried out based

on the holistic evaluative criteria developed by the researcher (see Appendix O); it’s a

five-level evaluation form using such criteria as (1) pronunciation, intonation, and

fluency, (2) organization, completeness, sequence, coherence, cohesion and

supporting details, (3) grammatical and syntactical structure and lexical use and (4)

paraphrase. The participants’ retelling performances in the pretest and posttest were

evaluated and then assigned to a level in a holistic fashion.

All the quantitative data obtained from the pretest and posttest was processed via

t-tests. The independent t-test was conducted to investigate whether there was a

significant difference between the EG and CG regarding a particular aspect of their

38

retelling performances. The paired-samples t-test was conducted to explore whether

there was a significant difference regarding a particular aspect of their retelling

performances between the pretest and posttest within the EG or the CG. In this case,

all the quantitative data gathered in the pretest were first processed via the

independent t-test to see if there was a significant difference between the EG and CG

in the pretest on a particular aspect of their story retelling performances. The fact

that no significant between-group difference was found in the pretest performances

indicated that the EG & CG were similar in their retelling ability before the study.

Under this condition, a paired-samples t-test was then conducted to see whether there

was significant difference between the pretest and posttest in each group. A

significant difference indicated that the participants in that group progressed

significantly from the pretest to the posttest on that aspect. When both groups

displayed a significant within-group difference, another independent t-test was

conducted on the posttest to see whether there was any significant difference in the

posttest. If there was a significant between-group difference in the posttest, it

suggested that the group with higher mean value in the posttest made more progress

than the other group. If there was none, it indicated that both groups made equally

significant progress.

Finally, the responses of the participants in the EG to the multiple-choice

39

questions in the posttest questionnaire were presented with descriptive statistics.

Their responses to the open-ended questions in the questionnaire and to the probing

questions in the interviews were categorized, synthesized and analyzed.

CHAPTER FOUR RESULTS AND DISCUSSION

In this chapter, the effects of the GO map instruction on students’ story retelling

performances are presented and discussed. The effects of the GO map instruction on

the word count are examined first. Next, the effects on the fluency are shown.

Third, the effects on the number and content of the story elements in the participants’

story retelling are addressed. Fourth, the effects concerning the holistic story

retelling performance are discussed. Finally, the results of the participants’

perceptions of the GO map instruction are delineated.
