资源简介:
Control condition using Cognitive Tutor for the Learning by Teaching baseline study with SimStudent.
Conditions are named xyz - x:pre-Test Version (A, B, or C), y:post-Test version (A, B, or C), z: intervention condition (SS for SimStudent or CL for CogTutor)
Outcome - BUG is common, expected misconception or error, ERROR is other, unexpected error.
Steps for scratchpad (multiply fractions) - pm-r-num-node (multiply numerators), pm-r-den-node (multiply denominators) and FinalAnswer
Selection - left is left hand side of equation, right is right hand side, strategic is transformation or other planning parts.
Action for simplification steps:
clt = Combine Like Terms
mt = Perform Multiplication (ie Multiply Terms)
rf = Simplify Fractions (ie Reduce Fractions)
rds = Simplify Signs
distribute = Distribute (obviously)
ivm = Invert and Multiply
Feedback classification: BUG is JIT pop-up for common misconception, HINT is requested hint, AUTOHELP is unrequested hint after repeated mistakes.
本研究为结合SimStudent的教学式学习基线研究,其对照组采用认知导师(Cognitive Tutor)。
实验条件以xyz格式命名:x为前测版本(A、B或C),y为后测版本(A、B或C),z为干预条件(SS代表SimStudent,CL代表CogTutor)。
结果分类规则如下:BUG指代常见的预期性误解或错误,ERROR指代其他非预期性错误。
分数乘法草稿步骤包含:pm-r-num-node(分子相乘)、pm-r-den-node(分母相乘)以及最终答案(FinalAnswer)。
选择分类规则如下:左侧代表方程式左半边,右侧代表方程式右半边,策略类指代变换或其他规划环节。
简化步骤的操作分类如下:
clt:合并同类项(Combine Like Terms)
mt:执行乘法运算(即项相乘,Perform Multiplication)
rf:化简分数(即约分,Simplify Fractions/Reduce Fractions)
rds:化简符号(Simplify Signs)
distribute:展开分配(Distribute)
ivm:颠倒相乘(Invert and Multiply)
反馈分类规则如下:BUG指针对常见误解的即时弹出提示(JIT pop-up),HINT指用户主动请求的提示,AUTOHELP指用户重复出错后自动弹出的非主动请求提示。
