Fonger, Nicole L.; Davis, Jon D.; Rohwer, Mary Lou – School Science and Mathematics, 2018
This research addresses the issue of how to support students' representational fluency--the ability to create, move within, translate across, and derive meaning from external representations of mathematical ideas. The context of solving linear equations in a combined computer algebra system (CAS) and paper-and-pencil classroom environment is…

Das, Pabi Maya; Faikhamta, Chatree; Punsuvon, Vittaya – Science Education International, 2018
This study investigated the development of Bhutanese students' views of the nature of science (NOS) as they engaged in an explicit and reflective approach. Seven aspects of NOS were integrated into the chemistry content in two learning units titled "matter and its composition" and "study of gas laws" over a time span of 6 weeks…

Schalk, Lennart; Schumacher, Ralph; Barth, Armin; Stern, Elsbeth – Journal of Educational Psychology, 2018
Instruction often starts with an explanation of a concept or principle before students are presented with problems to be solved. Recent research indicates that reversing this widely used tell-and-practice sequence (T&P) so that exploratory problem-solving precedes the instructional explanation (i.e., PS-I) might be more beneficial. We aimed to…

Urhan, Selin; Dost, Senol – International Journal of Science and Mathematics Education, 2018
Model-eliciting activities are problem-solving activities that differ from traditional problems as they include non-routine, open-ended, and complicated real-life situations with various solutions (Lesh & Doerr, 2003). According to Lesh, Hoover, Hole, Kelly and Post (2000), a model-eliciting activity must follow certain principles, namely, the…

Moore, Hadass; Benbenishty, Rami; Astor, Ron Avi; Rice, Eric – Journal of School Violence, 2018
Although homeless youth face a higher risk of victimization and mental health problems, little is known about school victimization and mental health outcomes for school-attending homeless youth. This study examined the relationship between school climate and school-related victimization and mental health problems among homeless youth. Multivariate…

Nawani, Jigna; Kotzebue, Lena; Rixius, Julia; Graml, Michael; Neuhaus, Birgit J. – International Journal of Science and Mathematics Education, 2018
This study investigated the effects of teachers' use of "focus questions" on students' knowledge structures and classroom teaching-learning process by re-analyzing selected data from a quasi-experimental pre-post video study (Wadouh, 2007). Focus questions are content-related anchoring questions highlighting the key content taught in…

do Amaral, Edenia Maria Ribeiro; da Silva, João Roberto Ratis Tenório; Sabino, Jaqueline Dantas – Chemistry Education Research and Practice, 2018
In this paper, we analyze the process of conceptualization experienced by students in Secondary School when involved in activities in a teaching and learning sequence on the concept of substance, considering the emergence of zones of the conceptual profile. The results point out that the approaches to different modes of thinking of substance…

Arana, Allyson A.; Boyd, Erin Q.; Guarneri-White, Maria; Iyer-Eimerbrink, Priya; Dougall, Angela Liegey; Jensen-Campbell, Lauri – Merrill-Palmer Quarterly: Journal of Developmental Psychology, 2018
Depressive symptoms, somatic complaints, and circulating levels of inflammatory biomarkers interleukin-6 (IL-6) and C-reactive protein (CRP) were examined as correlates of social and physical peer victimization in an ethnically diverse sample of adolescents (N = 91) using a multi-informant approach. Hierarchical regression analyses indicated that…

McPherson, Heather – Science Teacher, 2018
Students often confuse the functional differences between motion "transmission" and "transformation" systems. Students find it difficult to conceptualize differences between the specific systems. In this article, the author describes a technology and engineering unit that incorporates problem-based learning (PBL) to assist…

Rains, Stephanie; Whitworth, Brooke A. – Science Teacher, 2018
Alternative farming techniques are often more efficient and conserve resources more effectively than conventional farming, which can harm the environment with pesticides and synthetic fertilizers (Pimental 2005). To learn the theory, application, and related science concepts of sustainable farming techniques, students can collaborate to create an…
