We have a Drillster app update for you. It contains a brand-new drill player, which is now active by default. The biggest improvement of the new player is the way feedback is displayed. Feedback directly after every exercise is important for the learning effect. Therefore, it now has a (much) more prominent role. Regardless of your answer, the feedback section will tell you what was the right answer and why, so you learn from each exercise at that very moment. The app will now also tell you how long it will take you to reach 100% proficiency. Moreover, to make all of our lives better, we improved the way visuals, like videos and images, are shown. You can use visuals in questions, answers, and feedback. We doubt you’ll want to, but it’s possible to switch back to the previous player by going to settings and toggling ‘Built-in player’. Do tell us your reasons and give us your feedback (support@drillster.com), so we can improve. Thanks! WHAT'S NEW? The new default drill player means the following: - Higher performance - We improved the overall look & feel of the app; - It’s also more intuitive; - More gamification elements; - Better didactics; - More focus on the right answer after each exercise. Regardless of your answer: we focus on what was the right answer and why; - Feedback is better and more pedagogical displayed; - Visuals, like videos and images, are shown bigger and better to learners; - Last but not least: the learning curve graph has a more prominent role in the app. It will also tell you how long it will take you to reach 100% proficiency. To switch back to the previous player, go to settings and toggle ‘built-in player’.
