概括
学生的属性显著影响牛肉管理课程的学术成功,无论教学方法如何. 同行评价与考试成绩有很强的相关性,强调学生个人贡献,而不是教学格式.
科学领域:
- 农业教育 农业教育
- 动物科学动物科学
- 教育技术的教育技术
背景情况:
- 由于COVID-19大流行,高等教育的教学交付方法需要快速过渡.
- 了解这些变化对学生成绩和参与肉牛管理等专业课程的影响至关重要.
- 之前的研究已经探讨了影响学生成功的因素,但疫情引起的远程和混合学习的独特背景需要进一步调查.
研究的目的:
- 调查过渡性教学交付方法 (远程与面对面) 对学生考试成绩和小组项目同行评价在高级级肉牛管理课程中的影响.
- 确定在线参与度指标,同行评价和学业成绩之间的相关性.
- 为了确定预测成功的关键学生属性,无论课程的交付格式.
主要方法:
- 采用了准实验性的研究设计,比较了五个学期 (2019年秋至2021年春) 的不同教学格式.
- 学生的成绩被评估使用相同格式的考试 (封闭记号/1小时与开放记号/12-14小时) 和一个小组项目与同行评价 (0-10级).
- 包括ANOVA和相关性在内的统计分析被用来比较不同交付模式的考试成绩和同行评价,并探索与在线参与和学生特征的关系.
主要成果:
- 在远程和面对面 (F2F) 教学交付方法之间没有观察到总体考试成绩或小组同行评价的显著差异,除了第3次考试的一小部分例外.
- 在线参与度指标 (页面浏览量) 与考试3分的相关性很弱,但没有其他在线活动指标与考试成绩相关.
- 在同行评价成绩和所有四个考试成绩之间发现了强烈的相关性 (r = 0.33到0.45),项目组占考试成绩差异的28-37%.
结论:
- 个人学生的属性,而不是课程交付方法,似乎是学术成功的主要驱动力在这个牛肉牛管理课程.
- 同行评价是学生在考试中的表现的强有力的指标,表明了协作动态和个人贡献的重要性.
- 研究结果表明,有效的教学策略,以学生参与和团队工作中的问责制为重点,可能比教学方式更为关键.

Mutation, Gene Flow, and Genetic Drift
58.7K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Development of Antibiotic Resistance

Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...

Threats to Biodiversity
22.5K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Steps in Outbreak Investigation
155
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Genetic Drift

Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.
