We present the development and validation of a new assessment tool, the Moon Phases Concept Inventory for Middle School (MPCI-MS), a concept inventory about the phases of the moon targeting students aged 10 to 14 years old. Items in the questionnaire are based on a careful examination of the concept domain of phases of the moon, ideas and concepts necessary to understand the mechanism of lunar phases, as chosen by a panel of seven professional astronomers. Questions and multiple-choice answers were tested for readability with 5th grade students, tested for reading level, and submitted to a second panel of professional astronomers to check for face and construct validity of the items. The MPCI-MS was tested with N=296 students from grade 5 in elementary school to secondary 2 (M age=10.2 to 14.1). One item about global perspective on lunar phases had to be removed because of poor psychometric properties. The revised MPCI-MS has a post-test Cronbach alpha score of 0.786 and good overall psychometric properties: the mean difficulty index for the MPCI-MS pretest is 0.47, and 0.61 for the post-test; mean point-biserial correlation (post-test) is 0.376. Test-retest without instruction at one-week interval showed high test-retest reliability [M pre=13.696, M post=14.523; t(45)=1.315, p=0.192]. We conclude that the MPCI-MS is a reliable and valid instrument that can discriminate between novices and experts, and can be used to assess 10 to 14 year-old students' learning gains on the topic of lunar phases. The final version of MPCI-MS is a 19-item instrument, including two new questions about eclipses, that takes between 15 and 25 min for students to complete.

Earth and the Solar System (ESS1.B)
  • The orbits of Earth around the sun and of the moon around Earth, together with the rotation of Earth about an axis between its North and South poles, cause observable patterns. These include day and night; daily changes in the length and direction of shadows; and different positions of the sun, moon, and stars at different times of the day, month, and year. (5)
  • The solar system consists of the sun and a collection of objects, including planets, their moons, and asteroids that are held in orbit around the sun by its gravitational pull on them. (6-8)
  • This model of the solar system can explain eclipses of the sun and the moon. Earth's spin axis is fixed in direction over the short-term but tilted relative to its orbit around the sun. The seasons are a result of that tilt and are caused by the differential intensity of sunlight on different areas of Earth across the year. (6-8)
