Phylogenetic trees have become increasingly important across the life sciences, and as a result, learning to interpret and reason from these diagrams is now an essential component of biology education. Unfortunately, students often struggle to understand phylogenetic trees. Style (i.e., diagonal or bracket) is one factor that has been observed to…

Teaching Experimental Sciences is a compulsory subject in the Bachelor's Degree in Primary Education (BDPE). It belongs to the discipline of Education and to the field of "Knowledge of the social and natural environment", and consists of a total of 24 ECTS, of which 6 ECTS correspond to "Teaching Natural Sciences" (TNS). This…

Background: Argumentation is an important discourse process in science that needs to be taught and learned as part of a repertoire of strategies to support the acquisition of scientific literacy. Research in science education indicates that beliefs or perceptions and the epistemological orientations of teachers influence their approaches to…

In this study, middle school students' (8th grade, n = 24) problem-solving processes were investigated while implementing a design-based science learning (DBSL) approach. DBSL tries to incorporate science learning with the processes of engineering design. A DBSL module was developed by the research team within which students were expected to…

This paper describes an undergraduate laboratory experiment where students study the heating behavior of magnetic nanoparticles in the presence of alternating magnetic fields. Average score on the post-test was 45±12% for students who completed the lab online, versus 43±11% for those doing the activity hands-on. Post-test scores were significantly…

Federal legislation requires equitable access to education for all students at all levels, including in the postsecondary setting. While there have been a few studies in the chemistry education research literature base focused on how to support students with specific disabilities, this work seems to exist as a separate stream of research without…

Background: The continuation of teacher preparation activities after a 3-year Physics Teacher Education Coalition (PhysTEC) grant is used as a case study to examine multi-faceted aspects of sustainable change in higher education. Since teacher preparation is outside typical physics departmental activities, success is highly dependent on finding a…

Engaging learners in modeling practices can promote substantial science learning, and anchoring science teaching in societal issues can promote student motivation to learn and make learning experiences more meaningful. However, elementary teachers have had few prior experiences with either modeling or socioscientific issues (SSI) and so are…

The purpose of this study was to investigate what factors lead to disparate views of online teaching among faculty in the biological sciences. The population for this study included full-time community college and university faculty members teaching biology courses in northeast Texas. The study was conducted using an online survey that included…

In electromagnetism, to determine the direction of the electromagnetic force and magnetic field, the right-hand rule (RHR) is used. Previous researches show that students have difficulty in applying the RHR. This research is aimed to find out the factors which make it difficult for the students to apply the RHR. To achieve this, qualitative case…

Genetics as a core concept of life science is essential for understanding biology. Examining genetics understanding among biology majors is becoming important since they must necessarily achieve some level of genetics understanding to advance their career. This study compares Indonesian biology majors' genetics understanding with previously…

This paper presents a mixture item response tree (IRTree) model for extreme response style. Unlike traditional applications of single IRTree models, a mixture approach provides a way of representing the mixture of respondents following different underlying response processes (between individuals), as well as the uncertainty present at the…

Integrating sophisticated graphical analysis skills as they learn science is essential for K-12 students and emphasized in current standards. In this study, we iteratively designed a Graphing Integration Inventory (GII) over a three-year period, while also supporting students to develop their capabilities to use graphs to learn science content in…

This is a story about discovering a bias that affected participation grades in my Introductory Physics for Life Sciences class. My expectation, that actively engaged students tended to talk frequently in my presence as their teaching assistant, would have erased two students' outstanding performances if not for the participation grade policies…

Decisions related to career choice are influenced by person's interactions with his or her environment. The purpose of this study was to examine the characteristics of a STEM (Science-Technology, Engineering, and Mathematics) career choice. The study included two stages in which two different questionnaires were used. The purpose of the first…
