This study examined the effect of blended laboratory experiments on pre-service physics teachers’ (PSPTs’) attitudes toward physics laboratories. The research design was a quasi-experimental pre-test and post-test comparing groups. Participants were 63 2nd-year PSPTs’ enrolled in a physics diploma program from three colleges of teacher education. The treatment groups performed blended and virtual laboratory experiments, whereas the comparison group conducted real laboratory experiments. Data were collected before and after intervention using a 34-item adapted attitude toward physics laboratory questionnaire with a Cronbach alpha value of 0.765. Data were analyzed using descriptive statistics, paired-sample t-test, one-way ANOVA, and Tukey post hoc comparisons. The findings revealed a statistically significant difference in mean post-test results between the treatment and comparison group. The Tukey HSD post hoc analysis revealed that the difference in mean between blended and real was statistically significant, but not on other combinations. Descriptive statistics showed slight attitudinal improvement from pre-test to post-test. This improvement was statistically significant for blended and virtual groups but not in real groups. Blending physics laboratory experiments can be used to enhance attitudes toward physics laboratories. Based on the conclusions, recommendations are made.
