4.5. Exploratory Factor Analysis (EFA)
For the second phase, exploratory factor analysis (EFA) was performed on variables Culture learning
in Design and Technology. This analysis was conducted to identify and prioritize a large number of
questionnaires into constructs under a certain variable from the sample (Chua, 2009; Tabachnick &
Fidell, 2006).
EFA was conducted to get the best new construct from data that obtained from the study
sample (Hair, et.al, 2009: 773). The main purpose of EFA is to identify the constructs available in
selected variables to be used in other analyses. This process requires the process to drop items that are
not correlated to form single-construct in a questionnaire.
Analysis of these factors will be performed to confirm the collection of items in the
instrument Culture School and was clustered by factors that really represent the content aspects to be
evaluated as described by Nunnally (1978). Apart from the determination of the historical design of
the instrument is done, factor analysis conducted for the validity of the variables in the learning
culture of design and technology education.
Here is a step-by-step procedure proposed by the EFA as Hair et. al (2010), Tabachnick and
Fidell (2006), Sekaran (2000), Sheridan (2005), Sheskin (2007), Henson and Roberts (2006) and
Coakes and Steed (2005):

The above procedure was carried out repeatedly until formed the constructs with distinctive
items. It involves several iterations item rotation to form the constructs or components required and
has a distinctive items (Mahaliza, Norlia & Shahril @ Charil, 2011).
Chua (2009) states the determination of the items whether should be removed or not,
depending on the purpose of the study, if the purpose of the study is to make a distinction between the
constructs, the items should be removed because an item cannot be represented by two constructs in
the analysis comparison between the constructs. Factor analysis is a procedure used by previous
researchers to identify, reduce, and compiling the questionnaire items in the specific constructs under
a dependent variable in the study.
4.6. Factor analysis of variables Culture learning in Design and Technology
Exploratory Factor Analysis (EFAs) results in the learning culture in education Design and
technology explain procedures anti-image correlation analysis shows the correlation coefficient is
greater than 0.5, and this gives the impression that factor analysis can proceed. Measure of sampling
adequacy of the Kaiser-Meyer-Olkin (KMO) and Bartlett's Test of Sphericity showed that the KMO
value is .918, while the Bartlett Sphericity test is significant with the Chi-squarenya 5695.62 on 378
degrees of freedom.

An orthogonal rotation by varimax method was conducted to determine the factors in
explaining the variance in the number of Eigen values greater than 1. Orthogonal rotation is selected
to ensure that the observed variables are not correlated (jocko uncorrelated) to each other. Moreover,
it can make sure "factor structure matrix" fit and match "factor pattern matrix" when "factor
correlation matrix" is "Identity matrix" (Henson & Roberts, 2006). To determine the items belong to
certain factors, varimax method has been turning these factors with its own capacity. The main
purpose of this method is done to maximize the cargo variant with increased load factors high and
lower low values for each factor (Tabachnick & Fidell, 2006).
4.6.2. Total variance of constructs Cultural learning in Design and Technology
There are six components to the eigen value larger than 1. These six factors accounted for 56 864%
change in the overall variance. An orthogonal rotation by varimax method has been determined that
there are six factors to explain the total variance. Factor 1 accounted for 30 536% of the total
variance, and factor 2 of 7288% of the variance, factor 3, by 5944%, 4 factors of 4.784%, the factor of
5 by 4213%, and 6 factor of 4.098%. Other factors did not significantly contribute to the total
variance of the eigen value less than 1.

4.6.3. Varimax rotation for Cultural Components of learning in design and technology
education
To determine the items included in these factors, varimax method has been turning these factors with
its own capacity. Found 1 factor has 6 items, factor 2 has 6 items, factor 3 has 5 items, factor 4 has 5
items, as well as factor 5 has three items, factor 6 also has three items (see Table 11 below).
Based on the analysis of the above factors, the researchers found that one factor is the items
that represent Interactions With Student Teachers, factor 2 refers to Sharing Plans, factor 3 describes
the Emphasis on Education, 4th factors related to Safety and Regularity, factor 5 is about feelings and
cheer students, while the factor 6 is concerned with the readiness of teachers.

5.0 SUMMARY
The main purpose of this study is to report the validity and reliability of the items in the questionnaire
Culture School used to measure the views of secondary school students in Malaysia. This study uses
the basic theory and statistics to identify these items constituting 28 items Cultural learning in design
and technology. Questionnaire proposed learning culture in education Design and technology that
contains 44 items proposed by the validity of the expert analysis and exploratory factor analysis. Only
28 of an item is received and collected questionnaires to be learning culture in education Design and
technology of the final version. Factor analysis for the 28 items was created six key factors. Eigen
value indicates that the questionnaire items is more than one contributing factor to the total variance
of 56.86%. These factors is the emphasis on education, planning, sharing, security and orderliness,teacher and student interaction, emotion and excitement of students and teacher.

Results from this study suggest learning culture in education Design and technology
dimensions to produce the good reliability to measure student views on the role of school culture in
improving their academic performance. The reliability of the whole item of the six dimensions (28
items) in the actual study was .910. Therefore, these items suitable for use in exploratory research.
This study has its weaknesses and limitations of participants consisted of high school students
(grades 2) only. Therefore, future studies should be extended to primary school students, and also
involves principals and teachers as the most basic and important unit in developing the school's
academic success. But it is hoped that the instrument learning culture in education Design and
technology will be useful to researchers inventory especially interested to understand more about the
role of culture in learning design and technology education, particularly in boost academic
achievement of students in Malaysia as a whole.
