Friendships are important sources of support during adolescence. However, a growing literature indicates some adolescents co-ruminate, or talk with friends about problems in a way that is excessive, speculative, and negatively focused, which confers risk for internalizing problems.

Problematic mobile phone use can predict depression in adolescents, but few studies have thoroughly explored its internal mechanism. This study surveyed 1,768 Chinese adolescents in three educational levels (upper grades of elementary, junior middle, and high school levels) using a questionnaire. Results showed that (1) problematic mobile phone…

This study investigated preservice elementary science teachers' TPACK development throughout a science teaching method course. The pretest-posttest control group was used in the study. At the end of the study, a self-reported TPACK measure was administered to the experimental (n=26) and control (n=23) groups. The experimental group learned about…

Scholars have advocated for practice-based experiences, including high-leverage practices and metacognition, to be incorporated within preservice teacher programs, as they have the most pervasive impact on students' learning. One way in which teacher preparation programs have incorporated practice-based experiences is through the use of…

The progressive integration of mobile technology in the classroom is generating new scenarios to innovate teaching methods. The aim of this study was to analyse the perceptions of university students toward the use of Socrative and its implications in gamified learning situations. This is a descriptive-survey investigation, complemented with…

We explore the socio-ecological effects of meat consumption by assessing the impact of a didactical intervention. We focused on meat consumers' profiles, their willingness to engage in pro-environmental actions and the allocation of responsibility for environmental issues.

While past research has shown the Student Engagement Instrument (SEI) to be an adequate measure of school engagement, this self-report questionnaire currently exists as a number of different versions, each comprising various subsets of the original 35 items. The first objective of this study was to use confirmatory factor analysis to assess the…

"It is essential that we match our methodology with the psychology of the adolescent and as this changes throughout adolescence, so should our approach." Mike Waski provides an understanding of how to approach mathematics at the adolescent level from the perspective of the developmental characteristics of the age. Sharing observations…

This study examined the differential impact of implementing the "Self-Determined Learning Model of Instruction" (SDLMI) alone with implementing the SDLMI combined with "Whose Future Is It?" with transition aged students with intellectual disability in a cluster randomized trial in the state of Rhode Island. The state of Rhode…
