Technology and validation methods for producing biodiesel have been updated and have kept advancing. Creative raw materials used in producing environmentally friendly biodiesels have also attracted interest from scientists. Thus, learning and teaching methods on biodiesel production at the high school level need to be up to date. However, there…

The correct use of micropipettes has been investigated in an undergraduate, introductory lab experiment intended for chemistry and biology majors. This lab experiment involves the use of micropipettes for accurately mixing, transferring, and applying a specific amount of dye to a cotton bandana. The data resulting from this experiment is a color…

During the unprecedented and rapid spread of the coronavirus disease-2019 (COVID-19) around the World, students have been concerned about the disease as much as the rest of the global community. As a real-world problem, the COVID-19 pandemic with many different debatable facets has social and scientific components, impacts society, and shows…

We examined the predictive relationship between high school students' gender, ethnicity, science self-efficacy as measured by the Science Self-Efficacy Questionnaire composite score, teacher interpersonal behaviors (TIP) as measured by the Questionnaire on Teacher Interaction (QTI) scale scores, and science grade point average in an urban Title I…

This study aims to enrich a theme in the science course in the distance education process with augmented reality-based applications and to examine the effects of these applications on students' achievement and attitudes in science courses. A single group pretest and posttest experimental design was used in this research. The research group…

Research-based assessments (RBAs) measure how well a course achieves discipline-specific outcomes. Educators can use outcomes from RBAs to guide instructional choices and to request resources to implement and sustain instructional transformations. One challenge for using RBAs, however, is a lack of comparative data, particularly given the skew in…

Organic reaction mechanisms are often represented by the electron-pushing formalism and reaction coordinate diagrams. These representations pose a challenge to students because valuable information is encoded within each representation, and students must know how to reason about mechanisms using both. Hence, it is important to understand whether…

Scientific competencies, as defined in the German competency framework, describe the ability to think independently and act scientifically which is a central component of medical education. This report describes integration of scientific competencies into anatomical teaching. Based on findings seen in two consecutive years of dissection courses,…

During the COVID-19 pandemic, all on-campus activities were required to be adapted to a distance-learning format, which was especially challenging for practical courses. Molecular biology is a mandatory course for biology undergraduates at Universidade Federal Fluminense. To overcome the impossibility of practical activities, we proposed…

This study explores the form of curriculum documents and its implications for the enacted curriculum. In this study, the narrative voices that appear in the Scottish Broad General Education phase and the Swedish Compulsory phase of the curriculum are scrutinized in relation to the most likely reader of these documents--the teacher. The study…

To develop competency in science practices, such as data analysis and interpretation, chemistry learners must develop an understanding of what makes an analysis and interpretation "good" (i.e., the criteria for success). One way that individuals extract the criteria for success in a novel situation is through making social comparisons,…

Background and purpose: As clear mechanisms for motivating and engaging teachers in learning and working collaboratively with colleagues are scarce, this study explored supportive conditions of promoting teacher professional development on inquiry-based science teaching in a Professional Learning Community (PLC) and examined how teachers'…

Title I middle schools face challenges delivering effective inquiry-based science instruction within the framework of Title I requirements. The purpose of this basic qualitative study was to explore Title I middle school teacher and principal perspectives on and experiences with the challenges of delivering inquiry-based science instruction within…

This policy brief summarizes results from a survey of over 2,000 K-12 science teachers regarding their instruction related to COVID-19. Teachers were surveyed in the spring of 2020 shortly after school buildings closed. In addition, 40 teachers were interviewed. The brief also discusses implications and recommendations. [This brief is derived from…

Acceptance of human evolution seems to be the majority position for the U.S. population; however, acceptance of evolution among conservative Christian groups is low, sometimes below 50%. There are many different reasons for this low acceptance, leading to a significant disconnect between scientific specialists and the general population. This…
