The Effect of Using Computer Simulation on Students’ Performance in Teaching and Learning Physics: Are There Any Gender and Area Gaps?

Table 9

The t-test of independent samples (posttest) according to the method, gender (pilot), and the area (pilot).

		Levene’s test for equality of variances				t-test for equality of means
		F	Sig.	t	df	Sig. (2-tailed)	Mean difference	Std. error difference	95% confidence interval of the difference
									Lower	Upper
Posttest by gender (pilot)	Equal variances assumed	0.040	0.841	0.471	90	0.639	0.382	0.810	−1.227	1.990
	Equal variances not assumed			0.472	89.666	0.638	0.382	0.809	−1.225	1.989
Posttest according to the area (pilot)	Equal variances assumed	0.023	0.880	−2.853	90	0.005	−2.307	0.809	−3.913	−0.700
	Equal variances not assumed			−2.883	68.429	0.005	−2.307	0.800	−3.904	−0.710
