Hahn, Michael; Joechner, Ann-Kathrin; Roell, Judith; Schabus, Manuel; Heib, Dominik P. J.; Gruber, Georg; Peigneux, Philippe; Hoedlmoser, Kerstin – Developmental Science, 2019
Sleep spindles are related to sleep-dependent memory consolidation and general cognitive abilities. However, they undergo drastic maturational changes during adolescence. Here we used a longitudinal approach (across 7 years) to explore whether developmental changes in sleep spindle density can explain individual differences in sleep-dependent…

Scullin, Michael K. – Teaching of Psychology, 2019
Many students and educators know that sleep is important to learning, yet there exists a gap between their knowledge and behavior. For example, fewer than 10% of students sleep 8 hr before final exams. In the context of two undergraduate courses on sleep (N = 34), students could earn extra credit if they averaged =8.0 hr of sleep during final…

Halpin, Peter F.; Wolf, Sharon; Yoshikawa, Hirokazu; Rojas, Natalia; Kabay, Sarah; Pisani, Lauren; Dowd, Amy Jo – Developmental Psychology, 2019
Relatively little research has addressed whether conceptual frameworks of early learning generalize across different national contexts. This article reports on a cross-country measurement invariance analysis of the International Development and Early Learning Assessment (IDELA). The IDELA is a direct assessment tool for 3- to 6-year-old children,…

Kilmer, Nelson; Krehbiel, Joel D. – Physics Teacher, 2019
Gay-Lussac's law states that the pressure of an ideal gas is directly proportional to its absolute temperature if the volume is constant. Students observe this relationship by taking measurements on the pressure of gas in a flask or metal sphere at different temperatures and then extrapolate the data to estimate absolute zero. In our college…

Öztürk, Nagihan Boztunç – Universal Journal of Educational Research, 2019
In this study, how the length and characteristics of routing module in different panel designs affect measurement precision is examined. In the scope of the study, six different routing module length, nine different routing module characteristics, and two different panel design are handled. At the end of the study, the effects of conditions on…

Damrongpanit, Suntonrapot – Universal Journal of Educational Research, 2019
The purposes of this study were to test the structural validity and to test the parameters invariance of the self-discipline measurement model for good student citizenship among the models, using the data from the 1,047 complete questionnaires and the reducing length questionnaires with multiple matrix sampling technique. The sample size of this…

Raykov, Tenko; Marcoulides, George A. – Educational and Psychological Measurement, 2019
This note discusses the merits of coefficient alpha and their conditions in light of recent critical publications that miss out on significant research findings over the past several decades. That earlier research has demonstrated the empirical relevance and utility of coefficient alpha under certain empirical circumstances. The article highlights…

Nicewander, W. Alan – Educational and Psychological Measurement, 2019
This inquiry is focused on three indicators of the precision of measurement--conditional on fixed values of ?, the latent variable of item response theory (IRT). The indicators that are compared are (1) The traditional, conditional standard errors, s(eX|?) = CSEM; (2) the IRT-based conditional standard errors, s[subscript irt](eX|?)=C[subscript…

Lee, Mi Yeon; Francis, Dionne Cross – Teaching Children Mathematics, 2019
Children's literature can provide useful contexts for teaching mathematics. In this article, the authors discuss the use of the children's book "Measuring Penny" (Leedy 1997) to support Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010) related to length measurement. The authors first describe three types of misconceptions…

Quiliano-Terreros, Rocio; Ramirez-Hernandez, Darinka; Barniol, Pablo – Turkish Online Journal of Distance Education, 2019
Massive Open Online Courses (MOOCs) concentrate an important number of students and are set up as an alternative for acquiring knowledge and continuing education. The objective of this article is to analyze how the quality and effectiveness of the MOOCs were measured in empirical studies between 2012 and 2017. For which a systematic mapping study…

Cicek, Guner; Gorkem, Umit; Yamaner, Faruk; Gullu, Abdullah; Gullu, Esin – Journal of Education and Training Studies, 2019
In this study, it was aimed to determine the negative effect of different types of exercise on ovarian reserve of sedentary women. A total of 40 sedentary women who met the criteria for admission to work were categorized as aerobic exercise (AE; n:20; age: 33.0±2.0 years old) and strength exercise (SE; n:20; age: 32.7±2.1 years old) groups.…

Güllü, Abdullah; Güllü, Esin – Journal of Education and Training Studies, 2019
The aim of this study was to investigate the effect of recreational physical activity training on biomotor characteristics of 12-age group secondary school students. A total of 116 physically inactive male students in secondary school participated in this study as healthy and volunteer. Participants were divided randomly into three groups: the…

Alpullu, Aytekin; Demir, Gökalp – Journal of Education and Training Studies, 2019
The simplest and easiest type of physical activity for a healthy individual is walking. Development of technology day by day brought along inactivity and related diseases. The purpose of exercise is to prevent and slow down diseases caused by a sedentary lifestyle. The aim of the study is to reveal the effect of walking on body composition of the…

Ochs, Raymond – Biochemistry and Molecular Biology Education, 2019
Understanding redox reactions in biochemistry requires a clear grasp of three definitions: electron exchange, oxidation number, and oxygen atom insertion. Here, the electrochemical cell is explained for redox-active ions, introducing a new comparison between the measurement of midpoint potential and the measurement of initial velocity for enzymes.…

Kok, Karel; Priemer, Burkhard; Musold, Wiebke; Masnick, Amy – Physical Review Physics Education Research, 2019
In this study with 153 middle school students, we investigate the influence of the number of decimal places from the reading of a measurement device on students' decisions to change or keep an initial hypothesis about falling objects. Participants were divided into three groups, introduced to two experiments--the time it takes a free falling…
