Example of predicted answers and explanations (Only CENTRAL explanations) obtained from our model with different levels of fine-tuning.
| Question (1): Fanning can make a wood fire burn hotter because the fanning: Correct Answer: adds more oxygen needed for burning. |
| PathNet |
| Answer: provides the energy needed to keep the fire going. Explanations: (i) fanning a fire increases the oxygen near the fire, (ii) placing a heavy blanket over a fire can be used to keep oxygen from reaching a fire |
| ExplanationLP |
| Answer: increases the amount of wood there is to burn. Explanations: (i) more burning causes fire to be hotter, (ii) wood burns |
| Diff-Explainer ExplanationLP |
| Answer: adds more oxygen needed for burning. Explanations: (i) more burning causes fire to be hotter, (ii) fanning a fire increases the oxygen near the fire |
| Question (2): Which type of graph would best display the changes in temperature over a 24 hour period? Correct Answer: line graph. |
| PathNet |
| Answer: circle/pie graph. Explanations: (i) a line graph is used for showing change; data over time |
| ExplanationLP |
| Answer: circle/pie graph. Explanations: (i) 1 day is equal to 24 hours, (ii) a circle graph; pie graph can be used to display percents; ratios |
| Diff-Explainer ExplanationLP |
| Answer: line graph. Explanations: (i) a line graph is used for showing change; data over time, (ii) 1 day is equal to 24 hours |
| Question (3): Why has only one-half of the Moon ever been observed from Earth? Correct Answer: The Moon rotates at the same rate that it revolves around Earth. |
| PathNet |
| Answer: The Moon has phases that coincide with its rate of rotation. Explanations: (i) the moon revolving around; orbiting the Earth causes the phases of the moon, (ii) a new moon occurs 14 days after a full moon |
| ExplanationLP |
| Answer: The Moon does not rotate on its axis. Explanations: (i) the moon rotates on its axis, (ii) the dark half of the moon is not visible |
| Diff-Explainer ExplanationLP |
| Answer: The Moon is not visible during the day. Explanations: (i) the dark half of the moon is not visible, (ii) a complete revolution; orbit of the moon around the Earth takes 1; one month |
