摘要

本研究确定了化学教学使用技术如何影响学生的学习成绩和记忆。为达到研究目的,采用Solomon的四组准实验研究设计。采用单因素方差分析(ANOVA)和独立样本t检验对数据进行统计学检验。单因素方差分析显示,在成绩和留任方面,两试验组的平均得分分别与对照组的平均得分F (3.161)=88.568 (p0.05)和F (3.161)=14.75 (p0.05)有统计学差异。独立样本t检验实验组和对照组成绩、留任后均分的差异均有统计学意义(t (163)=16.05, p0.05; t (162.09)=7.61, p0.05)。独立样本t检验显示,实验组中男女学生的成绩或留用成绩的测试后得分为(t (42)=1.53;P0.05和t (38)=-0.465;p0.05,分别。这种干预对学生的成绩和保留率没有统计学上显著的性别相关影响。因此,可以想象得出这样的结论:结合技术的化学教学提高了学生的成绩和记忆力,但其效果是中性的。根据最近的研究,化学教师和教师培训计划应该使用技术整合的课程来帮助学生掌握和回忆化学键的概念。

Effects of technology-integrated chemistry instruction on students’ academic achievement and retention capacity
This study determined how chemistry instruction using technology affected student achievement and retention. To achieve the goal of the study, Solomon’s four-group quasi-experimental research design was used. The one-way analysis of variance (ANOVA) and independent sample t-test were used to statistically examine the data. A one-way ANOVA analysis revealed that, for achievement and retention, respectively, the mean scores of both trial groups showed statistically significant differences from the mean scores of comparison groups F (3.161)=88.568, p0.05 and F (3.161)=14.75, p0.05). The independent samples t-test on the achievement and retention post-test mean score of the experimental and comparison groups respectively, was statistically significant (t (163)=16.05, p0.05 and t (162.09)=7.61, p0.05). Independent sample t-test shows that male and female students’ post-test scores for achievement or retention in the experimental group results was (t (42)=1.53; p0.05 and t (38)=-0.465; p0.05, respectively. This intervention has no statistically significant gender related impact on students’ achievement and retention. Thus, it is conceivable to draw the conclusion that chemistry instruction that incorporates technology enhances student achievement and retention, but its effect is gender neutral. According to recent studies, chemistry teachers and teacher training programs should use technology-integrated lessons to help students acquire and recall chemical bonding concepts.
