概括
本科生化学实验室的学生更喜欢亲自比在线学习,报告更高的乐趣和更少的时间承诺. 然而,在两种教学模式中,非实践任务的学习成果在两种教学模式中都相似.
科学领域:
- 生物化学教育教育 生物化学教育
- 实验室课程设计 实验室课程设计
- 在线学习在线学习
背景情况:
- 本科生化实验室课程对于科学培训至关重要.
- 转向在线和混合学习模式的转变需要评估它们的有效性,而不是传统的面对面教学.
- 学生的参与和感知是成功实验室教育的关键因素.
研究的目的:
- 为了比较学生的学习成果和完全在线和完全面对面的本科生化实验室课程之间的感知.
- 评估讲师对在线与现场生物化学实验室教学模式的偏好和看法.
- 评估教学模式对学生在一个为期一个学期的生物化学实验室的经验的影响.
主要方法:
- 一个半学期的本科生化实验室课程的比较研究,提供在完全在线和完全面对面的格式.
- 学生可以自行选择自己喜欢的课程,两个课程都由同一位教师授课.
- 通过调查分析学生的感知,并通过形成性和总结性评估比较学习成果.
- 一项针对美国生物化学实验室教师的调查,他们都有这两种方法的经验.
主要成果:
- 面对面的学生报告了更高的课程享受,并认为它比在线学生耗时更少.
- 大多数接受调查的教师更喜欢面对面的模式,认为它更有效,更有吸引力,更愉快,耗时更少.
- 在线和面对面的组之间,在非实践学习目标和目标得分方面没有发现显著差异.
结论:
- 虽然面对面的生物化学实验室可以提供更好的学生体验,但在线模式可以实现某些学习目标的可比结果.
- 教师和学生的看法强调了对面学习的偏好,尽管需要进一步研究更大的样本大小.
- 这些发现表明,仔细的课程设计可以减轻在线生物化学实验室教学所感知的一些缺点.

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Leveling Effect and Non-Aqueous Acid-Base Solutions
8.1K
This lesson defines the leveling effect in acidic and basic solutions and its role in aqueous and non-aqueous solutions. It is essential to understand the competing nature of various species in a chemical system.
The Leveling Effect of a Solvent
A generic acid (HA) reacts with the generic base (B-) to yield the corresponding conjugate base (A-) and conjugate acid (HB):

Calculating Equilibrium Concentrations
47.9K
Being able to calculate equilibrium concentrations is essential to many areas of science and technology—for example, in the formulation and dosing of pharmaceutical products. After a drug is ingested or injected, it is typically involved in several chemical equilibria that affect its ultimate concentration in the body system of interest. Knowledge of the quantitative aspects of these equilibria is required to compute a dosage amount that will solicit the desired therapeutic effect.

Acid and Bases: Ka, pKa, and Relative Strengths
26.7K
This lesson delves into a critical aspect of the relative strengths of acids and bases. The strength of an acid is evaluated by the acid dissociation into its conjugate base and a hydronium ion in water. The complete dissociation of a strong acid is confirmed with a very high concentration of hydronium ions. As a result, an incomplete dissociation process affirms a weak acid. Therefore, the equilibrium is in the forward direction for strong acids and backward for weak acids in these reactions.
