This short paper presents an educational approach to teaching three popular methods for encoding DNA sequences: one-hot encoding, binary encoding, and integer encoding. Aimed at bioinformatics and computational biology students, our learning intervention focuses on developing practical skills in implementing these essential techniques for…

Histology is a preclinical subject transversal in medical, dental, and veterinary curricula. Classical teaching approaches in histology are often undermined by lower motivation and engagement of students, which may be addressed by innovative learning environments. Herein, we developed a serious game approach and compared it with a classical…

This ethnographic cross-case study examines five teachers' year-long efforts to implement practice-based physics instruction within the unique organizational context of a no-excuses charter network. The teachers were attempting to adapt their didactic, rigid, and compliance-based instructional approach to include more opportunities for students to…

Current science education reform efforts have identified sensemaking as an important goal of science education, and science education researchers have studied what constitutes the sensemaking process in the science classroom. Because the studies of sensemaking are loosely linked to those of scientific reasoning, however, they have provided little…

Preservice elementary teachers need to be able to engage young students in science practices but may not have extensive experiences with those practices. They also may have contrasting beliefs about them, which inform their teaching practice. To understand preservice teachers' beliefs related to science practices, we focus on the connections they…

A significant issue in the teaching, learning and summative assessment of practical science is that the underpinning model of scientific methods is based on a fairly simplistic and linear account that does not represent how scientists actually do practical work. In this paper, we examine how science teachers in England and Wales view scientific…

The purpose of this study is to examine pre-service chemistry teachers' orientations towards chemistry teaching during chemistry teaching method courses. This study was conducted with ten pre-service chemistry teachers for 28 weeks. The Draw-A-Science-Teacher-Test Checklist (DASTT-C), card-sorting activity, interviews, observations, and reflection…

To investigate the variation in active learning used in college science courses, the authors analyzed 57 comparison studies published in three prominent science education journals. Focusing on three sources of variation--(a) the active learning activities, (b) other pedagogical features, and (c) course structure/design--they found that most…

Effective science education is crucial for developing a scientifically literate citizenry, and for many, foundational primary science education experiences play a significant role in defining their long-term science trajectories. However, primary science education has been limited by a dissonance between the poor science trajectories for…

Prior research suggests most students do not glean valid cues from provided visuals, resulting in reduced metacomprehension accuracy. Across 4 experiments, we explored how the presence of instructional visuals affects students' metacomprehension accuracy and cue-use for different types of metacognitive judgments. Undergraduates read texts on…

Instructional practices in science education often create dichotomies of "expert" and "outsider" that produce distinct power differences in classrooms. Building upon the idea of "making present practice" to disrupt these binaries, this paper presents select findings from a year-long study investigating two urban…

This article aims to simplify and facilitate the process of practical teaching of enzyme kinetics by utilizing minimal teaching laboratory requirements. Simultaneously, it ensures that students comprehend the enzyme kinetics experiment effectively. The focus is on teaching students how to estimate the maximum velocity (Vmax) and Michaelis constant…

The focus of this case study is the question, 'How can research integrity be taught in higher education?' I will share my experience of teaching this topic over the past three years, organising the various dimensions of research integrity under the broader theme of integrity in science, specifically in terms of norms, functions, and unity. Norms…

This study examined the effect of design-based science instruction (DBSI) on sixth grade students' science achievement, as well as their development in relation to science process skills. 213 sixth grade students from three public schools participated in the study. A pilot was conducted in the unit of Systems of the Human Body and the main study…

Given the severe pollution caused by traditional plastics, biodegradable plastic products (BPPs) have received great attention and are appearing in people's lives in the form of packaging bags, tableware, etc. Whether a wide variety of BPPs can truly degrade depends on the environment. Aerobic composting is the arbitration method to evaluate the…
