Ichsan, Ilmi Zajuli; Hasanah, Risky; Ristanto, Rizhal Hendi; Rusdi, Rusdi; Cahapay, Michael Bobias; Widiyawati, Yeni; Rahman, Md. Mehadi – Online Submission, 2020
Science learning in the 21st century should develop the abilities of the students to find solutions to the problems. This task requires a set of skills called Higher Order Thinking Skills (HOTS) and innovative assessment should be designed to gauge the acquisition of these skills. Thus, this study aimed to create an innovative HOTS-based…

Livni-Alcasid, Gur A.; Haskel-Ittah, Michal; Yarden, Anat – Education Sciences, 2018
In genetics education, symbols are used for alleles to visualize them and to explain probabilities of progeny and inheritance paradigms. In this study, we identified symbol systems used in genetics textbooks and the justifications provided for changes in the symbol systems. Moreover, we wanted to understand how students justify the use of…

Mierdel, Julia; Bogner, Franz X. – Education Sciences, 2019
As effective methods to foster students' understanding of scientific models in science education are needed, increased reflection on thinking about models is regarded as a relevant competence associated with scientific literacy. Our study focuses on the influence of model-based approaches (modeling vs. model viewing) in an out-of-school laboratory…

Gonda, Rebecca L.; DeHart, Kyle; Ashman, Tia-Lynn; Legg, Alison Slinskey – American Biology Teacher, 2015
Achieving a deep understanding of the many topics covered in middle school biology classes is difficult for many students. One way to help students learn these topics is through scenario-based learning, which enhances students' performance. The scenario-based problem-solving module presented here, "The Strawberry Caper," not only…

Sonnleitner, Philipp; Brunner, Martin; Keller, Ulrich; Martin, Romain – Journal of Educational Psychology, 2014
Whereas the assessment of complex problem solving (CPS) has received increasing attention in the context of international large-scale assessments, its fairness in regard to students' cultural background has gone largely unexplored. On the basis of a student sample of 9th-graders (N = 299), including a representative number of immigrant students (N…

Mesmer, Karen – Science Scope, 2006
Genetics is often a fascinating but difficult subject for middle level students. They can see the results of genes in every organism, but trying to visualize what happens at the level of genes is challenging for concrete thinkers. The author discusses an approach that helps students understand how genotypes can translate into phenotypes, then…
