Proteins are essential for cell function, and their biological performance depends on three-dimensional (3D) structures. Insulin is made up of 51 amino acids and is a critical hormone involved in glycaemia regulation. In basic education, concepts involving proteins (synthesis, structure, interactions, and function) are abstract and difficult for…

There are concerns that ability tracking at a young age increases unequal opportunities for children of different socioeconomic background to develop their potential. To disentangle family influence and potential ability, we applied moderation models to twin data on secondary educational track level from the Netherlands Twin Register (N = 8847).…

Interdisciplinary engineering programs have many perceived benefits including developing broader skills and an ability to work with complex real-life problems. However, the development of interdisciplinary programs faces many challenges including how to balance breadth and depth, how to integrate interdisciplinary learning into existing studies…

Background: Spatial ability has an important place in science education, which is effective in raising future scientists. Although not in large numbers, studies show that teachers' spatial abilities somehow affect their teaching practices in the classroom and thus the spatial abilities of their students. Purpose: This study aimed to investigate…

This study aimed at designing instructional material named Biotechnology Instruction Module (BIM) which is enriched with active learning methods to enhance the 8th grade students' learning of the topic. The development of the teaching materials proceeded within the stages of the ADDIE instructional design model. The final form of the instructional…

A textbook model of a contagious disease, the dynamics of which are represented by the SIS epidemic model with saturating treatment, is considered. I show that this model, as originally formulated, is not dimensionally consistent. The model can be fixed by including a dimensional constant [alpha] of value one (with units individuals[superscript…

A common practice amongst scientists is to evaluate the connections between evidence and claims about natural and human-induced phenomena. Teacher education coursework may improve understanding of this important activity and facilitate teachers to implement evidential thinking approaches into their future science teaching. Instructional scaffolds…

Self-assessment and task selection are important self-regulated learning skills for secondary school students. More specifically, selecting new tasks based on self-assessments is very important for them, because teachers are not always present or able to select tasks for them individually. However, little is known about the processes underlying…

There is considerable variability in the extent to which young people with developmental language disorder (DLD) experience mental health difficulties. What drives these individual differences remains unclear. In the current article, data from the Twin Early Development Study were used to investigate the genetic and environmental influences on…

Purpose: This review article summarizes a program of longitudinal investigation of twins' language acquisition with a focus on causal pathways for specific language impairment (SLI) and nonspecific language impairment in children at 4 and 6 years with known history at 2 years. Method: The context of the overview is established by legacy scientific…

This research aims to explore the concept of mental model of students about genetic concepts through drawing-writing test. The participants were 85 students of Biology Education at University of Lampung, which has taken genetics course. Mental model of students was categorized into five levels (levels 1-5) based on coding framework which was…

Preterm birth and Neonatal Intensive Care Unit (NICU) stay are early adverse stressful experiences, which may result in an altered temperamental profile. The serotonin transporter gene ("SLC6A4"), which has been linked to infant temperament, is susceptible to epigenetic regulation associated with early stressful experience. This study…

This study aimed to measure the contribution of summarizing and questioning in the Reading-Questioning-Answering (RQA) learning model integrated with mind mapping on the genetic learning outcomes. This study was a correlational research and has been analyzed using multiple regressions. Mind mapping, summarizing, and questioning were positioned as…

The plant taxonomy textbooks that are generally used in colleges need to be complemented with a DNA-based molecular review. In general, plant taxonomy textbooks devote more space to morphology than to molecular-level characteristics. The research reported here used the results of DNA-based research to develop a molecular plant taxonomy textbook.…

Across the globe, from the very wealthy continents of North America to Europe to Australia, the phenomenon of migrant and immigrant students outperforming native students are observed and documented. Some migrants and immigrants from China, the Philippines, India, Russia, Africa, and the Caribbean are reportedly achieving higher test scores than…
