Students face several challenges when transitioning to a new school level. This necessitates an exploration of the personal features supporting their adjustment, which may provide valuable insights for intervention programs and counseling services at institutions. We employed a sample of 9th- to 10th-grade high school students (N = 255) and 1st-…

One hundred four students aged 8 to 16 worked on one Fermi problem involving estimating the number of people that can fit in their school playground.

Marlene Chesney describes a piece of research where the participants were asked to complete a calculation, 16 + 8, and then asked to describe how they solved it. The diversity of invented strategies will be of interest to teachers along with the recommendations that are made. So "how do 'you' solve 16 + 8?"

This paper explored variation of strategy use in pattern generalization across different generalization types and across grade level. A test was designed to assess students' strategy use in pattern generalization tasks. The test was given to a sample of 1232 students from grades 4 to 11 from five schools in Lebanon. The findings of this study…

Research has consistently demonstrated the negative consequences of depression on adolescents' functioning in peer and family relationships, but little work has examined how depressive symptoms affect the quality of adolescents' and emerging adults' romantic relationships. Five waves of data on depressive symptoms, romantic relationship conflict,…
