The purpose of this study was to enhance grade 11 students' conceptual understanding of fundamental acid-base models using Predict-Observe-Explain based animated movies (POE-AM). Twelve grade 11 students participated in the study. To collect data, the students' responses to the POE-AM tasks and interview protocols were used. The findings indicated…

This experimental study was undertaken with preservice teachers to test whether the use of science integration into arts education increases demonstration of science details and creative features in artwork. Two conditions were created: arts-focused and science-focused; gouache still-life paintings were produced and analyzed, and an attitude…

This study aims to report the development an instrument that is standardized (reviewed by validity, reliability, and difficulty index) to detect science misconception in an elementary school teacher. This study used a 4-D model; defining, designing, developing, and disseminating. First, it was prepared with 47 opened-ended questions, and then it…

The Green Ninja Film Academy (GENIE) is an interdisciplinary curriculum development project that examines the efficacy of combining climate science concepts and practices with digital storytelling for middle school youth. We present findings from iterative enactments of this design-based research project in 2017 (N = 296) and 2018 (N = 539). On…

Research into the efficacy of modules featuring dynamic visualizations, case studies, and interactive learning environments is reported here. This quasi-experimental 2-year study examined the implementation of three interactive computer-based instructional modules within a curricular unit covering cellular biology concepts in an introductory high…

We examined the variation in Force and Motion Conceptual Evaluation (FMCE) preclass scores according to the type of physics class a student had in high school. This was done for students who had taken Physics 1 at a highly selective university. The majority of students had taken an Advanced Placement (AP) physics course, allowing us to examine in…

Background: Increasingly, high dropout rates in science courses at colleges and universities have led to discussions of causes and potential support measures of students. Students' prior knowledge is repeatedly mentioned as the best predictor of academic achievement. Theory describes four hierarchically ordered types of prior knowledge, from…

The purpose of the current research was to determine the opinions and alternative concepts of the pre-service science teachers about the functions of the elements found in a simple electric circuit. The current research was carried out with the participation of the first-year students attending the Science Teaching Department of a state university…

Practicing chemists use models, diagrams, symbols, and figures to represent phenomena which cannot be detected by the human senses. Although research suggests that these external representations (ERs) can also be used to address the challenges that students have in learning chemistry, it is not clear how instructors' use of ERs aligns with their…

The aim of this study was to determine the effects of cooperative learning and models on the conceptual understanding of the chemical reactions. The sample of study was comprised of 71 preservice science teachers from the first grade of science teacher education program. Quasi-experimental method with pre-and post-test of quantitative research was…

This article focuses on students' discursive moves and reasoning practices while engaged in a task that requires making explanatory links between sickle cell disease and malaria. Both diseases pertain to key areas of the biology curriculum, namely, genetic variability and natural selection, and are connected to the theory of evolution of living…

The Human Orrery is a representation of the Solar System at a human scale, on which positions of planets over time are symbolized by different discs. Learners can then walk along the orbits of the planets with the right pace. This pedagogical tool uses the principles of enacted cognition to promote a better understanding of the scientific laws of…

Investigating real-world phenomena in a playful, exploratory setting is a natural process for young children. Teachers can capitalize on children's curiosity to foster their understanding of science ideas and their engagement in science practices, such as predicting, experimenting, observing, comparing, and contrasting. Force and motion…

Through the experiments described in this article, students become acquainted with the principles behind ternary liquid-liquid systems and/or Aqueous Two-Phase Systems (ATPS), and their characterization by the determination of the binodal curve, tie-lines, tie-line lengths and critical point, as well as in applying the non-random two-liquid model…

Formative assessment is a teaching method that helps to determine the prior knowledge of students, schedule the course plan accordingly, give it the final shape based on the feedback received from students, and encourage conceptual learning. The aim of this study is to introduce the "annotated student drawings" as one of the common…
