Indigenous learning lab as prefigurative political action to dismantle settler-colonial system of exclusion

ABSTRACT American Indian students continue to experience marginalization in settler-colonial school systems in the United States. American Indian students receive disciplinary punishment more frequently and harshly than white peers. Overrepresentation of American Indian students in school discipline is a byproduct of a long history of oppressive settler-colonial schooling. To address racial disproportionality in school discipline, the Indigenous Learning Lab was enacted through building a university-school-family-community partnership at a rural high school. Learning Lab is a community-driven problem-solving process through which multiple school stakeholders take transformative actions, including identification of systemic challenges entrenched in the settler-colonial school system and design of a new, culturally responsive support system. White administrators and teachers, along with students, family, and community members from the local tribal nation, engaged in prefigurative political action as they participated in the collective design process of the new system. Prefiguration is a present embodiment of new social relations, allowing participants to try new decision-making structures that may lead to what can be considered possible futures. The purpose of this paper is to examine how school stakeholders exerted their collective agency to unpack systemic contradictions in the settler-colonial school system and design a new culturally responsive support system.

Learning lab skills online: Lessons from implementing video-based instruction for a remote biotechnology lab.

The COVID-19 pandemic forced many courses to move online, presenting a particular challenge for hands-on laboratory courses. One such course in our Biotechnology track is an advanced Protein Interactions lecture/laboratory course. This 8-week course typically meets for 5 h a week in the laboratory space. For the Fall 2020 version of the course, first-person videos were produced for each of the laboratory experiments, and the corresponding experimental data produced by students in previous semesters were provided for the current students to analyze in their electronic lab notebooks and lab reports. Student perspectives and assessments were collected on course participants from Fall 2019 (in-person laboratories) and Fall 2020 (online laboratories) to compare experiences and outcomes. Analysis of the data shows that the online students appreciated the videos and gained self-confidence in the procedures, but maintained more misconceptions about the material. In addition to being unable to perform the hands-on experiments, other factors such as anxiety could also be interfering with the learning process under the pandemic conditions. The implementation process for the remote labs, student reactions, and lessons learned are discussed.

Mathematical Modeling in Teacher Education — Developing Professional Competence of Pre-Service Teachers in a Teaching–Learning Lab

At the Muenster University, teaching–learning labs have been integrated into teacher education as part of a joint initiative by the German federal and state governments in order to improve the quality of teacher education. Because of the great potential in natural differentiation and the particular challenge in teaching, mathematical modeling was placed at the focus of the teaching–learning lab. The paper deals with the structure of an innovative and supportive learning environment that fosters the diagnostic competence of mathematical modeling as part of the professional competence of pre-service teachers. With the help of a newly developed test instrument, it was shown that the development of modeling-specific diagnostic competence increases significantly and with a large effect size in the teaching–learning lab for mathematical modeling, while no significant changes occur in a control group (CG).

The effect of high-fidelity simulation technology on the competency of nursing students in managing chemotherapy extravasation in patients with cancer.

Nursing education suffers from a lack of high-quality clinical experiences for students, especially among medical specialty groups such as cancer patients, in Saudi Arabia. A paucity of empirical evidence is supporting simulation in education and the transfer of psychomotor skills to patient care. In particular, although generally recognized as an essential oncology nursing skill, effective strategies for teaching the management of chemotherapy extravasation to students have not been investigated. To investigate the effects of high-fidelity simulation (HFS) technology on the competency of nursing students in the management of chemotherapy extravasation and the transfer of this skill from traditional learning labs to clinical settings. A quasi-experimental study comprising a two-group pretest-posttest with repeated measures was used. The intervention was a scenario-based, HFS. Third-year students (n=68) from a nursing program were randomly allocated to either intervention or control groups. Competency was measured in both groups using the same standardized assessment checklist. Competency scores were lower in the control group compared to the intervention group at both posttesting times. These results, however, were not statistically significant. There was no statistically significant difference between the groups regarding skill transfer. Nursing faculty can use either HFS or traditional learning methods to effectively teach students how to manage chemotherapy extravasation and transfer this skill to clinical settings.

Contradictions as an entry into inclusive systemic design: Addressing racial disparities in the discipline at an urban middle school

In the United States, school disciple has been racialized. Youth from racially minoritized backgrounds receive exclusionary discipline more frequently and severely for more subjective reasons such as disrespect, excessive noise, and dress code violation in U.S. schools. The study presents how an urban school community in Wisconsin engaged in inclusive knowledge-production and systemic design process, Learning Lab, to collectively examine and address racial disparities in school discipline. Learning Lab members (school staff, parents, and community representatives) engaged in root cause analysis behind disproportionality in their local context and identified the manifestations of the systemic contradiction (racial disproportionality) as dilemmas, conflicts, critical conflicts, and double binds in everyday practices of the school community. They collectively designed a new culturally responsive school-wide behavioral support system to address the systemic contradiction. We identified 194 discursive manifestations of contradictions in the 14 meetings of the Learning Lab. These manifestations stemmed from three main contradictions as tensions between components in the school activity system related to classroom management, school-community partnership, and behavioral support tools.

Moving Forward: Resilience of a Chemistry for Health Professions 2D Virtual Lab Program During COVID

Chemical education laboratory practices have not been exempted from the present healthcare crisis. Learning environments have shifted from face-to-face exercises to virtual and video conferencing platforms. Here, we discuss a chemistry for health sciences course which (i) adapted the previous face-to-face laboratory exercises to 100% online using online platforms two years preceding COVID only to shift to completely remote learning and back again and (ii) highlight correlations between chemistry concepts (e.g., pH, solubility, and serial dilutions) and medical practices. Additionally, course pass/fail trends pre-COVID and during COVID are identified and discussed by the author. Regarding example laboratory teaching and learning, this article further examines the responses for two groups of students and their perspectives on 2D virtual chemistry lab experiences and parallel discussions in healthcare: (1) For group 1, students (n = 135) completed an anonymous and voluntary Likert-type questionnaire for a pH and serial dilution online lab experience with over 92% recommending the lab experience for future enrollees, and (2) for group 2, student (n = 107) results indicated 93% of the survey participants were providing the same recommendation.

Preparation and Testing of Food Freshness Indicators: an Application-Oriented Learning Module Integrating Basic Concepts of Microbiology and Chemistry Laboratory.

ABSTRACTWe describe a novel 4-day food microbiology laboratory learning module for a first-year, introductory undergraduate course. In the module, the students test the suitability of four different pH indicator dyes as freshness indicators for dairy products. The concepts of serial dilutions, microbial growth, microbial metabolism, pH as well as pKa, and basic microbial laboratory practices are a part of the designed activity. It is a relatively inexpensive module and can be executed with little infrastructural support. It can be delivered as a stand-alone structured inquiry. The associated variables and applications indicate that the activity can perhaps be developed into a more elaborate course-based undergraduate research experience, or CURE.

Unicorns and Blessings: Supporting Culturally Diverse Twice-Exceptional Learners Through Learning Lab

Twice exceptional (2e) students are students who are both gifted and have a disability. At the intersection of exceptionality and race, twice exceptional students from racially minoritized communities may experience behavioral difficulties in schools. In this article, we provide information for educators as well as school and district administrators about the unique challenges and possibilities in teaching 2e students of color. We offer a research-based collective problem-solving process, Learning Lab, that brings together practitioners, students, school and district leaders, families, and community members, especially those who have been excluded from schools’ decision-making activities. Learning Lab members engage in root cause analyses, map out their existing behavioral support system, and design a culturally responsive school wide behavioral support model in response to experiences, resources, needs, and goals of 2e students and their school contexts. In Learning Labs, the local school community has power in determining the future of their school. Practitioners, students, family and community members’ diverse histories and interests are utilized to develop just, effective, and gifted schools for all.

Facilitating innovation through lab projects: cases from experience-based tourism

ABSTRACT Collaborative innovation approaches, such as innovation labs, have the potential to enhance innovation in experience-based sectors. However, they are rare and understudied. This study investigates the facilitation of innovation lab projects in experience-based sectors. The theory of transformational leadership and team learning is explored in the context of four idea-generating lab projects in Norway. This multi-case study involves two cases that focused on meal experiences and two on cultural experiences. The findings show that short-term team learning can be facilitated using the four transformational leadership dimensions. This study contributes to leadership theory by identifying 10 new sub-dimensions within three of the dimensions. These include three new sub-dimensions within the inspirational motivation dimension, two within the intellectual stimulation dimension, and five within the individualized consideration dimension. The findings have practical implications for the facilitation of learning and ideation in tourism innovation labs.

Digital Twinning remote laboratories for online practical learning

ABSTRACT The COVID19 pandemic has demonstrated a need for remote learning and virtual learning applications such as virtual reality (VR) and tablet-based solutions. Creating complex learning scenarios by developers is highly time-consuming and can take over a year. It is also costly to employ teams of system analysts, developers and 3D artists. There is a requirement to provide a simple method to enable lecturers to create their own content for their laboratory tutorials. Research has been undertaken into developing generic models to enable the semi-automatic creation of virtual learning tools for subjects that require practical interactions with the lab resources. In addition to the system for creating digital twins, a case study describing the creation of a virtual learning application for an electrical laboratory tutorial is presented, demonstrating the feasibility of this approach.

Learning outcomes of university chemistry teaching in laboratories: A systematic review of empirical literature

AbstractLaboratory work has been a common element of science courses at university level for around two centuries, but its practice has been criticised by scholars in the field and related stakeholders. Mainly on a rationale of financial justification and educational efficacy, more evidence for learning has been called for. The aims of this systematic review were to characterise learning in the laboratory and substantiate learning outcomes associated with laboratory instructions in university chemistry. Analysis of 355 empirical studies revealed that students develop five clusters of laboratory‐related competences pertaining to experimental competences, disciplinary learning, higher‐order thinking and epistemic learning, transversal competences as well as affective domain. These competences were specified into related constructs measured in the studies. Synthesis of published studies led to a substantiated view on multidimensional learning in the laboratory and its implications for research, practice and theory are suggested. Representations of research areas that deserve appraisals and further investigations are also proposed. The video abstract for this article is available at https://video.ku.dk/secret/76185334/73665cb966315601404b793ffc234a77. Context and implicationsRationale for this studyTo provide comprehensive evidence for learning outcomes associated with laboratory work.Why the new findings matterOur research synthesis substantiates a multidimensional view of laboratory learning. There is a large scope for empirical and theoretical development in this complex setting.Implications for researchers and practitionersFuture research should be directed towards a more comprehensive and rigorous inquiry into student learning that considers a more holistic view. Focus on higher‐order competences is needed. Practice wise, laboratory curricula should better accommodate students' learning progression throughout their higher education. Assessment and feedback practices should be revisited.
