Marking Correct Answers WRong??
I've noticed that T4L has a really bad habit of marking correct answers wrong. Is there a specific reason for this? It's VERY confusing to the child and it happens at least 5 or 6 times a session. Math is the WORST for this. Anything I can do about this?

Can you give a specific example? Often this happens because of how the answer was input. For example, if the student hits the space bar before or after his answer, the program "thinks" the space is a character and "knows" there isn't a character like that in the answer, so it is marked wrong. A parent looking at the answer would not notice the slight space.
Another problem is typing the letter "o" instead of a zero.
The most frequent reason for one of my own daughters getting stuck is her failure to find ALL of the right answers. In the gamestyle math lessons, the student is often given several answers to choose from, and is told to choose the answers that meet a certain criteria. There could be one, two, three, or more correct answers to the problem. The student must click on all of the correct answers and not click on any of the incorrect answers in order for the problem to be marked "correct".
A specific example (lesson activity number and problem) would help to pinipoint the reason for what you are experiencing. I'll be happy to work through any examples you provide.

Well for instance, he was doing a math portion of his lesson plans and the problem said to round the two numbers, and then find the sum of the two numbers. He did fine on the first two, but the last two were counted wrong even though they were right.
5000 + 4000 = 9000. All of it was typed in correctly, but it was still marked wrong. Both numbers were rounded right, and added correctly. It did the exact same thing on the second problem, with different numbers.

I bet a little fix on your/your child's part will solve this problem. Try adding the comma after the thousands place. Even though technically correct without it, the computer program does not accept the answer without the comma. We learned this by trial and error also.

Was it this kind of a rounding problem, discussed in this previous thread?
I have five kids using Time4Learning, and once in awhile a child comes to me for clarification about something that has been marked wrong. So far, we haven't found any errors, although I've had to think carefully a few times to understand why.
When grading work, a computer can't reason what the student "probably" meant by his answer (the way a human can), so answers must be input "just so". This is the nature of computer programs. The comma Carla mentioned is another example of a machine's inability to reason. Sometimes it takes some practice to get accustomed to "thinking" like a computer.
Nothing is foolproof, though, and if there is an actual programming error, it needs to be corrected. If this happens again, please provide the lesson activity number and a description of the problem, so someone can test it. Thank you.

my child just completed a quiz today (multiple choice) and two of his answer were marked incorrect when I believe they are the correct answers. My understanding of the strategy of making 10 would be to make the first number so its easier to subtract. 128 would be 122=10 therefore you would have 108 not 106 or 105 and 146 would be 144=10 therefore you would have 106 not 102 or 103.

Hi kvoj,
I am sorry for any confusion this has caused. Please contact [email protected] with the grade level, subject, chapter, activity name and number so that they can test the activity and alert the developer. We appreciate your feedback.
