黑白斯特asks quiz questions to help students understand
随着学生通过模拟进步，每个Labster虚拟实验室都会造成多种选择问题。这些问题是上下文相关，具有挑战性的，并且必须在可能继续下一步之前回答。他们旨在帮助学生通过经验工作。
It’s not easy to “game” these questions. Each student sees the unnumbered questions in a randomized order, and that order changes each time they re-attempt a correct answer. In other words, there's no way to get through it without carefully reading the answer options each and every time!
The best way to correctly answer a Labster quiz question is to click on the Theory tab in the Labpad and read the Theory pages. All the answers can be found there!
尽管如此，有些学生将永远试图作弊。在某些情况下，这些学生已经能够找到Labster测验问题的答案，这些问题由他们的同行在网络上发布的问题。Labster非常认真地提出这个，所以请与我们分享这些违规行为，我们将尽最大努力让他们删除。未来，Labster将开发一个新功能，以便允许教师修改和自定义测验问题。

如果您的一些学生发布并分享到Web上的Labster嵌入式测验问题的答案，您能做什么？
Here are some of our suggestions:
View Labster as a formative assessment rather than a summative assessment. Many teachers reduce the grade impact of Labster quizzes and use them as feedback to help students identify the gaps in their understanding (as well as their achievements).
根据实验，概念和实验室的实验，概念和技术制定自己的总结评估。
Stay tuned for a future feature from Labster that will permit quiz customization.
Here are some reasons why Labster quiz questions can be powerful learning tools:
1. Questions help motivate students to find the answers
对于学生来说，它可以觉得测试的目的是产生一个成绩，而不是评估和推进他们的学习。
黑白斯特’s quiz questions feel different.
We use an embedded, “assess as you go” approach so students can learn from input and feedback without feeling like they are taking a test. The more students become aware of their own improvement, the more likely they are to feel motivated to learn.
“When students play Labster, they learn and are assessed at the same time. It’s actually the same for most games you play for fun. Nobody playing World of Warcraft would say “oh, I’m being assessed on my skills as an alt warrior” — obviously they are, but it doesn’t feel like it, and it’s not boring. Whether you win or not, whether you complete the level or not, there’s an assessment. And it’s hugely motivating.``
- Mads Bonde，Labster联合创始人
2. Labster’s Quiz Questions Support Student-Centered Learning
Many instructors use Labster questions to help students to recognize and correct their own knowledge gaps, and therefore limit the impact of Labster quiz results on final course grades.
Within the Labster experience, students can access explanatory learning content (Theory pages) and useful hints that help them find the right answer to the questions.
在传统的实验室课程中，小组中工作的学生经常依靠他们的实验室合作伙伴的观察和分析。在Labster中，班上的每个人都有机会 - 以及责任 - 尝试答案并获得反馈。
Teachers can review students’ progress in the Labster Dashboard, observe the number of attempts and correct or incorrect responses, and provide one-on-one coaching as needed.
从形成性评估接收反馈与学生为中心的学习原则，因为它支持学习者积极构建自己的知识的能力（Nicol＆Macfarlane-Dick，2006）。Labster的直接反馈为学生提供了有助于他们在其他课程评估中取得成功的指导，这些评估可能对其成绩产生更大的影响。
Ways to Assess Students with Labster Quiz Questions
大多数教师价值技术帮助他们节省了自动化的分级，特别是当他们有远程和混合课程或高名招生科学课程时。
黑白斯特quiz scores are automatically calculated and can provide important and timely information to instructors as well as students.
当您考虑如何在课程中使用评估时，反思您在为完成LABSTER的任务分配信贷方面可能有用。
也许您发现应用成绩价值增加了您学生完成虚拟实验室的可能性。
这是一个完全有效和重要的考虑因素。在这种情况下，Labster测验分数可以在仍然实现目标时携带相对较低的影响。
We’ve seen that instructors using Labster often grade students on the score from their “best” attempt at the quiz rather than their first attempt.
“For my lab course…the Labster scores are worth very little. I think it’s about 5 percent of their mark. They get multiple attempts and I count the highest one. I really want it to be more like a gamified intervention.”
– Felicia Vulcu, Associate Professor of Biochemistry and Biomedical Sciences, McMaster University
