Despite the great development of smart phone programs and applications, and the wide-spread of these devices among students, their use for the educational purposes remains weak. The study aimed to investigate to what extent utilizing mobile learning as an adjunct to classic classroom lectures affect students' academic achievement and, to assess their attitude toward using mobile application as an instructional method in dental education.
A quasi-experimental study was conducted among undergraduate dental students from two Sudanese universities. A total of 67 students who voluntarily agreed to participate were randomly allocated into a control group of 33 and an intervention group of 34 students. Initially, the two groups undertook a pre-test to ensure the standardization of a scale regarding their existing academic knowledge of dental surgery forceps used for tooth extraction. Then the intervention group was provided with a mobile application (Dental Surgical Forceps application version 2.1.0.0), and 3 weeks later a post-test was given for both groups. The attitude of the students toward the effectiveness of mobile learning was as assessed by five-point Likert scale questionnaire. For comparison of the numerical parametric data, a T. test was used, while for non-parametric categorical data a Chi-Squire test was used, with level of statistical significant difference set at P-value of ≤0.05.
The response rate was 91% for the intervention group (31 out of 34 students completed the study), and 78% for the control group (26 out of 33 students completed the study). Statistical significant difference was observed between the pretest and post-test mean scores of the intervention group (P < 0.005), while the differences were not significant among the control group (P > 0.05). Regarding the attitude of the dental students, the mean scores of the sample indicate that the vast majority of the participants (93.5%) showed positive attitude regarding the effectiveness of mobile learning.
There is a marked difference in the students' scores regarding their knowledge of dental surgical forceps. The students showed positive attitude toward using the mobile application.
尽管智能手机程序和应用有了很大发展,且这些设备在学生中广泛普及,但它们在教育目的方面的应用仍然较少。本研究旨在调查将移动学习作为传统课堂讲授的辅助手段在多大程度上影响学生的学业成绩,并评估他们对在牙科教育中使用移动应用作为教学方法的态度。
在苏丹两所大学的本科牙科学生中进行了一项准实验研究。共有67名自愿同意参与的学生被随机分为对照组33名和干预组34名。最初,两组进行了预测试,以确保用于评估他们对用于拔牙的牙科手术钳现有学术知识的量表标准化。然后为干预组提供了一个移动应用程序(牙科手术钳应用程序版本2.1.0.0),3周后两组都进行了后测试。通过五点李克特量表问卷评估学生对移动学习有效性的态度。对于数值参数数据的比较,使用T检验,而对于非参数分类数据,使用卡方检验,统计学显著差异水平设定为P值≤0.05。
干预组的回复率为91%(34名学生中的31名完成了研究),对照组为78%(33名学生中的26名完成了研究)。干预组的预测试和后测试平均分数之间观察到统计学显著差异(P < 0.005),而对照组之间的差异不显著(P > 0.05)。关于牙科学生的态度,样本的平均分数表明绝大多数参与者(93.5%)对移动学习的有效性持积极态度。
学生在牙科手术钳知识方面的分数存在显著差异。学生对使用移动应用程序持积极态度。
