learning resources; and able to access Internet. In addition, classroom is equipped with Wi-Fi connection; students’<br />

seats were allocated to facilitate groups’ discussion, and equipped with small laptop for each student named<br />

Classmate PC (CMPC). From 10 selected schools of 10 different states, a total of 304 out of 608 students were<br />

randomly selected to participate in ‘Constructivism Learning Environment Questionnaire (CLEQ) survey. After<br />

cleaning the data, this resulted in 291 usable questionnaires. Thus, 96% usable responses rate was achieved.<br />

Analysis of the measurement of the constructs<br />

The construction of CLEs Model was accomplished among several stages: (a) exploratory list of terms identified<br />

as: relevancy, uncertainty, critical voice, shared control, and student negotiation, (b) content validity which had<br />

been employed by careful selection of dimensions based on related literature revision and suggested methods for<br />

constructs and scale development obtained from pretested studies (Churchill, 1978, 1999), (c) construct validity<br />

with implementing discriminant validity that showed correlation among constructs are less than 0.9. (Hair et al.,<br />

2006), and convergent validity that, all items had loadings higher than 0.40. Further, convergent validity was<br />

ensured with Composite Reliability (CR) of 0.92 and an average variance extracted (AVE) of 0.53 (Hair et al.,<br />

2006). (d) Consistency reliability has been evaluated by computing the Cronbach’s alpha coefficients for each<br />

scale (Table 1). All six of the subscales possess internal reliability of alpha greater than .70. The Kaiser-Meyer-<br />

Olkin (KMO) value is .805, and Bartlett's Test of Sphericity indicates that the significance level (sig) for<br />

Sphericity (2263.059) for the six-item correlation matrix is highly significant (p
