schools or clubs in West Java. Beside coaches,
BBCTEP of MGS also involved 40 beginner student-
athletes aged 10-12 year old (M
years
=11.5; SD = .65),
consisting of 20 male student-athletes (M
years
=11.6;
SD = 1.30), and 20 female student- athletes (M
years
= 11.12; SD = 0.56), coming from two badminton
schools or clubs in Bandung. All student-athlete
participants were chosen through disproportional
stratified sampling technique (Johnson &
Cristensen, 2012) and divided into four groups.
2.2 Measurement
2.2.1 Workshop
The result of the workshop was measured by cognitive
test and affection scale assessment. Cognitive test was
used to measure the level of coaches’ mastery of the
workshop materials on the cognitive behavioral
component (Anderson and Krathwohl 2001;
Näsström, 2009). The test compiled 30 multiple
choice items and the result of split half reliability
estimation analysis arrived in Spearman-Brown
Prophecy reliability coefficient index =. 86.
The participants’ affective self-interest response to
the workshop was measured by two questions
(Hidayat, 2016) “what do you feel when you involved
in the workshop activities (pleasant, average, less
pleasant, unpleasant)”, and “what do you think of this
workshop activity (interesting, average, less interesting,
uninteresting).
2.2.2 Coaching Practical Training (CPT)
The observation of CPT was used to determine the
level of skill of the BBCTEP of MGS participants in
implementing MGS concept in the process of BBS
training (Hidayat, 2016). The measurement indicator
was based on the indicator of motor skill learning
process stages, including opening activities, main
training activities, and closing activities (Suherman,
2009; Hidayat, 2016; Hidayat & Sukadiyanto, 2016),
and elaborated into 9 (nine) out of 14 categories of
coaching behaviour in the Arizona State University
Observation Instrument or ASUOI (Lacy & Darst,
1984; Claxton, 1988; Isabel, Sobrinho, Antonio,
Felismina, & Michel, 2008), consisting of
preinstruction, concurrent instruction, post instruction,
questioning, manual manipulation, positive modelling,
hustle, praise, and management category. The result of
Lawshe’s content validity ratio (CVR) showed content
validity coefficient index (CVCI) between .60 -1.00.
CVCI in total = .89 (93.7%), .81 (89.8%) for opening
activities, .87 (92.1%) for main training activities,
and .96 (97%) for closing activities. According to one
way ANOVA (interclass correlation coefficient / ICC)
analysis technique, it was found that the total
reliability coefficient index among observers =.90, .94
for opening activities, .84 for main training activity,
and .95 for closing activities.
2.3 Procedure
BBCTEP of MGS consisted of workshop and CPT.
Workshop was conducted in classroom learning
through discussion, simulation, and role play.
Meanwhile, CPT was a training activity in the field in
the form of coaching practices (Vealey & Greenleaf,
2001; Weinberg & Gould, 2015; Hidayat, 2016). The
procedure of BBCTEP of MGS was conducted as
follows.
(1) Every participant followed workshop activities for
two days to study the way of designing and
developing MGS and its integration in the BBS
daily training program. The materials of the study
included: (a) BBS workshop analysis and the basic
concepts of MGS implementation on beginner
children student-athlete (day one), and (b)
workshop of approaches and MGS and CPT
learning structure (day two). The workshop process
was conducted in four stages (Boyett & Boyett,
1985), involving experience forming (participants
involved in group activities), reflection (the process
of reflecting their involvement in group activities),
conceptual forming (giving meaning on their
involvement in group activities), and conceptual test
(dialogical and multi-logical process between
participants and facilitators about the concept that
had been built that created a concept that might be
different with the existing conceptual design.
(2) Every participant did cognitive test before workshop
was begun (pre-test), at the end of the workshop
(post-test 1), and after CPT (post-test 2).
(3) CPT is a coaching practice to play a role as a
coach in the process of training (Hidayat 2016)
with the goal to implement MGS concept in the
process of BBS training. In this CPT activity, the
participants were divided into four groups based on
their GS type, including product goal group (G-1),
process goal group (G-2), the combination of product
and process goal group (G-3), and MGS group (G-
4). Each group consisted of 6 (six) persons (three
couples of coach) and all CPT groups received GS
and BBS intervention.
(4) CPT was conducted for two days, first day for
training under the coordination of facilitator, and 1
(one) last day for CPT of each group. The duration
of each CPT is 130 minutes. There were 3 (three)
