Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The conception of many people that the Sun is overhead at noon is a result of the lack of observation of natural phenomena. This article begins by presenting a review of the literature showing researches on the conceptions of students of different school levels and teachers on the subject. It mentions the knowledge of indigenous and other cultures of the past about the passage of the Sun by the zenith during the year. After this, the movement of the Earth around the Sun is discussed showing the regions of our planet that may have the Sun overhead at some time of the year. Different didactic models are also presented, taking into account the heliocentric, geocentric and topocentric referentials to address such contents with teachers and students.
