Designing for Student-Directedness: How K–12 Teachers Utilize Peers to Support Projects

Student-directed projects—projects in which students have individual control over what they create and how to create it—are a promising practice for supporting the development of conceptual understanding and personal interest in K–12 computer science classrooms. In this article, we explore a central (and perhaps counterintuitive) design principle identified by a group of K–12 computer science teachers who support student-directed projects in their classrooms: in order for students to develop their own ideas and determine how to pursue them, students must have opportunities to engage with other students’ work. In this qualitative study, we investigated the instructional practices of 25 K–12 teachers using a series of in-depth, semi-structured interviews to develop understandings of how they used peer work to support student-directed projects in their classrooms. Teachers described supporting their students in navigating three stages of project development: generating ideas, pursuing ideas, and presenting ideas. For each of these three stages, teachers considered multiple factors to encourage engagement with peer work in their classrooms, including the quality and completeness of shared work and the modes of interaction with the work. We discuss how this pedagogical approach offers students new relationships to their own learning, to their peers, and to their teachers and communicates important messages to students about their own competence and agency, potentially contributing to aims within computer science for broadening participation.

Decision Making in English as an Additional Language: Surprises and Advantages

Do adult learners of English make different and sometimes better decisions in English than their monolingual peers and teachers? It is likely, possible, and probable. Using evidence from classroom decision making studies, with over 500 participants, we demonstrate that often adult English learners (henceforth adult Active Bilingual Learners/Users of English [ABLE]) make more accurate decisions in English than first language English speakers, when given time and the ability to utilize their whole linguistic repertoire (i.e., translanguaging). We specifically look at differences in decisions that involve 1) common adverbs of frequency (rare, possible, likely, frequently, etc.) and 2) system 1 (implicit) vs. system 2 (analytical) thinking in cognitive reflection tests, such as math story problems. Understanding these surprising differences and advantages in decision making in English as an Additional Language (EAL) has important practical implications for test preparation and daily instruction for adult ABLE students, and potentially as well for ABLE youth in K-12 schools.

Applying Relatedness to Explain Learning Outcomes of STEM Maker Activities

A growing interest has been observed among K-12 school educators to incorporate maker pedagogy into science, technology, engineering, and mathematics (STEM) education to engage students in the design and making process. Both cognitive engagement and emotional engagement of students can be promoted through satisfying the psychological need of relatedness that concerns a sense of connection and belonging. How to support relatedness would influence the effective development of students’ cognitive competencies, namely creativity and critical thinking, and non-cognitive characteristics, namely interest and identity. Therefore, the present study investigated how two relatedness support strategies—real-world problems (RWP) and mentoring influence the development of student’s STEM-related cognitive competencies and non-cognitive characteristics in STEM marker activities. We implemented a 7-week intervention study with three classes of Grade 9 students (aged 13–15 years) in Hong Kong (n = 95). Three intervention conditions were designed in the experiment, comprising textbook problem (TBP), RWP, and RWP with mentoring (RWPM). Our analysis showed that (i) the differences in creativity among the three groups were non-significant, (ii) the RWP and RWPM groups showed stronger critical thinking than the TBP group, and (iii) the RWPM group exhibited stronger STEM interest and identity than the other two groups. This study revealed the effectiveness of adopting RWP strategy in developing secondary students’ perceived cognitive competencies (e.g., creativity and critical thinking) and the feasibility of employing a mentoring mechanism for cultivating learners’ perceived non-cognitive characteristics (e.g., STEM identity and interest). Hence, we also offered practical suggestions for teachers.

Ecuadorian and Uruguayan teachers' perceptions and experiences of teaching online during COVID

PurposeThe COVID-19 pandemic is a unique event that forced K-12 schools to rethink the delivery of instruction to protect the well-being of school system stakeholders. Teachers, school administrators and parents had to adapt to and embrace new ways of teaching and learning by utilizing available technology. The purpose of this study is to examine the challenges encountered by in-service teachers when moving from face-to-face to online teaching.Design/methodology/approachThis study utilized a qualitative phenomenological research methodology to examine Ecuadorian and Uruguayan teachers' perceptions and experiences transitioning from face-to-face to online teaching during the COVID-19 pandemic. This comparative study used convenience sampling to include 12 K-12 teachers from Ecuador and Uruguay.FindingsThe results of this study produced two themes that evidenced the demands placed on educators. The first theme was job demands, relating to teachers' perceptions about workload, preparation time and curriculum issues. The second theme related to available support provided by the school administrators and technology issues faced by teachers and students. Even though the teachers demonstrated adaptability for educating students during the pandemic, the experiences from both countries should be considered by teacher training programs and in post-graduate professional development.Originality/valueThis article examined how COVID-19 affected teachers in Uruguay and Ecuador. Data analysis documented the challenges encountered by teachers transitioning to online learning during the pandemic. The findings inform a larger audience about the needs of teachers working online.

Hydrogen production in an aerobic environment by Escherichia coli K-12

Escherichia coli (E. coli) is a facultative anaerobe that can grow in a variety of environmental conditions. In the complete absence of O2, E. coli can perform a mixed-acid fermentation that contains within it an elaborate metabolism of formic acid. In this study, we use cavity-enhanced Raman spectroscopy (CERS), FTIR, liquid Raman spectroscopy, isotopic labelling, and molecular genetics to make advances in the understanding of bacterial formate and H2 metabolism. It is shown that, under anaerobic conditions, formic acid is generated endogenously, excreted briefly from the cell, and then taken up again to be disproportionated to H2 and CO2 by formate hydrogenlyase (FHL-1). However, exogenously added D-labelled formate behaves quite differently from the endogenous formate and is taken up immediately, independently, and possibly by a different mechanism, by the cell and converted to H2 and CO2. Our data support an anion-proton symport model for formic acid transport. In addition, when E. coli was grown in a microaerobic environment it was possible to analyse aspects of formate and O2 respiration occurring alongside anaerobic metabolism. While cells growing under microaerobic conditions generated endogenous formic acid, no H2 was produced. However, addition of exogenous formate at the outset of cell growth did induce FHL-1 biosynthesis and resulted in formate-dependent H2 production in the presence of O2.

An Autoethnographic Report on the Use and Impact of Social Networking Sites as an Approach to Teaching of the Research Process

The establishment of the K-12 curriculum has had a significant impact on subject requirements related to the outcome-based education plan and the requisite output for a given research report or requirement. Social networking platforms enable students to effortlessly complete a variety of tasks, such as learning and performance. By intervening in research, social networking sites break down the barriers that limit both students and teachers in the research process. Three methodologies or ideas have arisen, known as approaches, that could help you facilitate teaching research, even if you are not in the research discipline: the Facebook-Personality Network Approach, the Virtual Research Journal, and the Google Immersion Approach. It is considered favorably by some students and users, but there are those who take advantage of its negative aspects. Instead of focusing on the emerging ideas or topics created by coding, I used social networking sites to demonstrate that research can be done anytime, anyplace, for any purpose or cause. According to the outcome-based education paradigm, students found the three techniques highly engaging. In order to be a teacher-researcher, you must utilize your originality and resourcefulness when it comes to all of the resources, devices, and technology, as well as the available social networking sites.

A Mission-Based Argument for Private K-12 Student Press

Although the First Amendment does not guarantee student press within public schools, it does help affirm the value of such opportunities to student communities. Private schools do not enjoy such constitutional support, but may have a more powerful tool closer to home: their own school mission statements. This study coded nearly 500 private K-12 school mission statements to determine whether the priorities identified by these programs align with the documented benefits of student journalism and found a strong connection between both.
