摘要

目的是确定研究方法对大陆大学生物学专业学生的学术表现(SP)的影响。为此,在应用研究方法之前,对对照组和实验组的学生SP进行了评估和比较;随后,实验组进行了研究方法的学习。最后,比较两组研究方法应用前后的SP。采用F Fisher检验和t Student检验对结果进行分析。正态性分析采用夏皮罗-威尔克正态性检验,同质性分析采用费雪检验。结果表明,对照组的SP前检验均值为6.69,标准差为1948,变异系数为29.1%;试验组的SP前检验均值为6.66,标准差为1961,变异系数为29.7%。因此,两组的SP相同,均质(CV> 15%),方差和(SD)相等。对于后测中实验组的SP,经Student t检验,在95%置信度下得到平均值为11,53,SD为2,874,CV为24.9%,证明实验组的后测平均SP大于各自前测的平均值,因为P值(Pr (| t| > |t|) = 0)小于通常显著性水平0.05。综上所述,研究方法对大陆大学学生在生物课上的表现有积极的影响。

Metodología indagatoria y rendimiento académico de estudiantes de la Universidad Continental, 2014
The objective was to determine the effect that research methodology has on academic students’ performance (SP) majoring in biology at the Universidad Continental. For this purpose, before applying the research methodology, a control and experimental group of students SP were evaluated and compared; afterwards learning sessions about research methodology were applied in the experimental group. Finally, SP was compared before and after the research methodology application in both groups. The results were analyzed using F Fisher and t Student test. Normality was analyzed according to normality Shapiro test - Wilk and the homogeneity, according to F Fisher test. Results showed that the average pre SP test was 6, 69 for the control group with a 1,948 standard deviation (SD) and 29,1 % coefficient of variation (CV), whereas the experimental group was 6,66 with a 1,961 standard deviation (SD) and 29,7 % CV. Therefore, the SP in both groups were identical, homogeneous (CV> 15 %), with equal variances and (SD). Respect to the SP in the experimental group in the post test, an average of 11,53 with a 2,874 (SD) was obtained and 24,9 % CV by Student t test at 95 % confidence, which proves that the average SP of the experimental group in the post-test is greater than the average in the respective pretest, since the P value (Pr (|T|> |t|) = 0) is less than the usual significance level of 0,05. In conclusion, the research methodology has a positive effect on the academic students’ performance in Biology class, at the Universidad Continental.
