Düsing, Katharina; Asshoff, Roman; Hammann, Marcus – Journal of Biological Education, 2019
This study investigates students' conceptions of the carbon cycle with regard to the components they believe to be relevant to the carbon cycle, how they interrelate these components, the ways in which they trace carbon atoms, and the different levels of biological organisation they consider when doing so. A total of 142 students aged 13-16 years…

Ye, Jianqiang; Lu, Shanshan; Bi, Hualin – Chemistry Education Research and Practice, 2019
This study uses graphs of conductivity measured by a microcomputer-based laboratory (MBL) to promote students' macro, micro, and symbolic representations when learning about net ionic reactions (NIR). A total of 54 students, aged 14-15 years old participated in this research, and were randomly divided into an experimental group (N = 27) and a…

Ceuppens, Stijn; Bollen, Laurens; Deprez, Johan; Dehaene, Wim; De Cock, Mieke – Physical Review Physics Education Research, 2019
We design, validate, and administer a 24-item test to study student understanding of linear functions in 1D kinematics [x(t)] and mathematics [y(x)] in the 9th grade. The items assess identification and comparison of initial position and velocity in 1D kinematics and of the y intercept and slope in mathematics using a graph or an algebraic…

Crujeiras-Pérez, Beatriz; Jiménez-Aleixandre, Maria Pilar – Research in Science Education, 2019
This paper examines students' engagement in monitoring anomalous results across a 2-year longitudinal study with 9th and 10th graders (14-15 and 15-16 years of age). The context is a set of five inquiry-based laboratory tasks, requiring students to plan and carry out investigations. The study seeks to examine students' interpretation of data, in…

Moodley, Kimera; Gaigher, Estelle – Research in Science Education, 2019
An exploratory case study involving six grade 9 science teachers was undertaken to probe how teachers' understanding of learners' misconceptions relate to their perceptions about teaching simple circuits. The participants' understanding of documented misconceptions in electricity were explored by means of a questionnaire, while their perceptions…

Sun, Meilu; Du, Jianxia; Xu, Jianzhong; Liu, Fangtong – Psychology in the Schools, 2019
The current study validated the Homework Goal Orientation Scale (HGOS) for secondary school students. Results revealed that HGOS consisted of two distinct but related subscales: mastery-approach and performance-approach. Given satisfactory measurement invariance, the latent mean differences were then examined across gender (males vs. females) and…

Jaik, Katharina; Wolter, Stefan C. – Journal of Education and Work, 2019
We empirically investigate whether the relationship between the fraction of filled apprenticeships in a particular occupation in the past and the fraction of prospective apprentices having very early intentions to train in this occupation has an impact on the decision to change the intended choice of occupation. We use a unique dataset from…

van Leendert, Annemiek; Doorman, Michiel; Drijvers, Paul; Pel, Johan; van der Steen, Johannes – Journal of Visual Impairment & Blindness, 2019
Introduction: Braille readers encounter difficulties when reading mathematical expressions. In this exploratory study, we created a setting to investigate these difficulties. Method: Using a motion-capturing system, we analyzed the tactile strategies of three braille readers while they read mathematical expressions. To compare tactile with visual…

Lupo, Sarah M.; Tortorelli, Laura; Invernizzi, Marcia; Ryoo, Ji Hoon; Strong, John Z. – Reading Research Quarterly, 2019
The purpose of the study was to determine whether easy or challenging versions of texts, when accompanied by different types of instructional support, improved adolescents' reading comprehension, particularly for students with below-average reading comprehension. The authors examined 293 ninth-grade students' reading comprehension of 24 leveled…

Hild, Pitt; Gut, Christoph; Brückmann, Maja – Research in Science & Technological Education, 2019
Background: Several different measures have been proposed to solve persistent validity problems, such as high task-sampling variability, in the assessment of students' expertise in 'doing science'. Such measures include working with a-priori progression models, using standardised item shells and rating manuals, augmenting the number of tasks per…

van den Berg, Yvonne H. M.; Burk, William J.; Cillessen, Antonius H. N. – Developmental Psychology, 2019
This study examined associations between perceived popularity trajectories and changes in proactive and reactive aggression in middle adolescence. The sample included 1,374 adolescents from 5 cohorts who were followed from Grade 7 to Grade 9 (49% males, M[subscript age] = 12.67 years, SD = 0.67). Popularity trajectories were identified based on…

Adelabu, Folake Modupe; Makgato, Moses; Ramaligela, Manto Sylvia – Electronic Journal of e-Learning, 2019
The use of dynamic geometry computer software (DGCS) is important in educational environment, and it is more advantageous for learning mathematics comprehensively. This study examined the importance of dynamic geometry computer software on learners' performance in geometry. A quasi experimental, non-equivalent control group was used. The…

Chen, Wei-Ru; Chen, Li-Ming – Educational Studies, 2019
The current scales for self-blame are not suitable for school bullying scenarios and most lack validity. This study used a self-developed scale to measure bullied victims' tendency to self-blame and further examined whether victims and bully/victims exhibited different tendencies toward self-blame under both bullied and generalized scenarios. The…
