Digital droplet PCR (ddPCR) merupakan salah satu teknologi PCR terbaru yang diklaim memiliki keunggulan dibanding teknik qPCR. Prinsip kerja teknik ini yaitu membagi sampel menjadi molekul-molekul kecil yang dipisahkan oleh emulsi minyak, air, dan senyawa penstabil sehingga membentuk droplets. Teknik ini memiliki kelebihan mampu melakukan kuantifikasi absolut maupun relatif pada DNA dengan konsentrasi sangat rendah, tidak memerlukan kurva standar, serta tidak sensitif terhadap kehadiran senyawa inhibitor. Teknik ini telah diaplikasikan pada kegiatan analisis molekuler tanaman di antaranya kegiatan pengukuran konsentrasi DNA dengan sangat akurat, deteksi kehadiran patogen pada jaringan tanaman, dan estimasi jumlah salinan T-DNA pada proses transformasi genetik.Kata kunci: PCR; droplet digital PCR; DNA; biologi molekuler; alat deteksi ABSTRACTOver the past decades, PCR technique has provided enormous benefits in molecular biology research activities. Digital droplet PCR (ddPCR) is one of the latest PCR technologies that is claimed to have advantages over the qPCR technique. The working principle of this technique is to divide the sample into small molecules, which separated by emulsions of oil, water, and stabilizing compounds to form droplets. This technique has the advantage of being able to perform absolute and relative quantification with very low DNA concentrations, does not require a standard curve, and less sensitive to the presence of inhibitor compounds. This technique has been applied to a number of plant molecular analysis, such as for measuring DNA concentrations very accurately, detecting the presence of pathogens in plant tissue, and estimating the copy number of T-DNA in the genetic transformation process.Keywords: PCR; droplet digital PCR; DNA; molecular biology; diagnostic tool.
A Field Programmable Gate Array (FPGA) Based Non-Linear Filters for Gas Turbine Prognostics
Authors: Nayak Jayant Kumar , Prasad Vatsala , Ganguli Ranjan 
Published: April 2021

The removal of noise from signals obtained through the health monitoring systems in gas turbines is an important consideration for accurate prognostics. Several filters have been designed and tested for this purpose, and their performance analysis has been conducted. Linear filters are inefficient in the removal of outliers and noise because they cause smoothening of the sharp features in the signal which can indicate the onset of a fault event. On the other hand, non-linear filters based on image processing methods can provide more precise results for gas turbine health signals. Among others, the weighted recursive median (WRM) filter has been shown to provide greater accuracy due to its weight adaptability depending on the signal type. However, sampling data at high rates is possible which needs hardware implementation of the filter. In this paper, the design, simulation and implementation of WRM filters on the FPGA (Field Programmable Gate Arrays) platforms Vivado Design Suite by Xilinx and Quartus Pro Lite Edition 19.3 has been performed. The architectural detail and performance result with the FPGA filters when subjected to abrupt and gradual fault signal is presented.

Not Making the Grade: A Narrative Inquiry Into Timmy’s Experiences With the Mandated Curriculum
Authors: Houle Sonia T. 
Published: April 2021

This research draws on the experiences of a Grade 1 delayed reader, his parents, and his teachers, to show his lived curriculum across his home and school contexts. This narrative inquiry is situated in the literature of curriculum studies, in the notions of the lived curriculum and curriculum-making. Field texts include field notes from the classrooms, transcripts of conversations with the child, his parents, and his teachers. For this paper, I illustrate the child’s experiences at the end of Grade 1, among the tensions created between the lived curriculum of a struggling reader, and the expectations of the mandated curriculum, which are shaped by institutional and sociocultural narratives. My goal is to provide insight into making curriculum in schools that accounts for the lived curricula of all children.Keywords: lived curriculum; narrative inquiry; curriculum-making
Educational Relevance of the Arts in a Technocratic World
Authors: Glen Carla 
Published: April 2021

Today, it is important to acknowledge our investment in the technologized visual culture world, but at the same time within that investment, allow for active participation in forms that press for engagement and reflection. Theorized through phenomenology, embodiment, and performative inquiry, Arts’ Educational Relevance in a Technocratic World presents an awakening of space moments of possibilities through active and interactive participation in installation art forms that press for participatory inquiry, engagement, and reflection with our close entanglement with the technologically driven visual culture world, the world in which we dwell, in relationship to our selves and others.Keywords: visual culture; installation art; phenomenology; enactivism; performative inquiry
Michael Apple, Social Theory, Critical Transcendence, and the New Sociology: An Essay
Authors: Brown Douglas 
Published: April 2021

Michael Apple has changed educational review and study significantly over the past 35 years. He has written numerous books and articles, centering upon education and power, curriculum theory and research, cultural politics, critical pedagogy, as well as advancing the development of the democratic school. Challenging social and political orthodoxy Michael Apple has altered the way scholars and educators approach schooling in North America, situating school life and schooling at the centre of educational theory and practice and, undeniable, social critique. This essay reviews and appraises some of these changes. It follows Michael Apple’s scholarship, acknowledging the theorists profound influence over educational theory and the critical process.Keywords: Critical Pedagogy; Michael Apple; Education; Resistance; New Sociology of Education
Disrupting Ignorance and Settler Identities: The Challenges of Preparing Beginning Teachers for Treaty Education
Authors: Tupper Jennifer 
Published: April 2021

In the fall of 2008, the Provincial Government of Saskatchewan announced mandatory treaty education for all students in K-12 schooling. Given the foundational importance of treaties and the treaty relationship to Canada, and ongoing reconciliation efforts with First Nations people, this initiative is to be celebrated. However, a central concern exists regarding the implementation of treaty education in Saskatchewan schools. To that end, this paper discusses research, with 348 predominately white, teacher education candidates at the University of Regina, regarding their knowledge, (mis)understandings, and experiences with treaty education, in both grade school and university contexts. Using critical race theory as a lens through which to conceptualize and make sense of the research, along with theories of ignorance as an epistemological exercise, the paper illustrates the imperative of enacting treaty education given (white) settler students struggles(and refusals) to connect their own social and economic privileges to treaties.Keywords: Treaty education; critical race theory; curriculum
Culturally Relational Education In and With an Indigenous Community
Authors: Donald Dwayne , Glanfield Florence , Sterenberg Gladys 
Published: April 2021

The unfolding of our work with Eagle Flight First Nation prompts us to reflect deeply on what it means to do research in and with an Indigenous community. This paper presents three stances that we considered when invited to “do research” in an Indigenous community around mathematics education: a mathematically deficit response, a culturally deficit response, and a culturally relational response. By considering the meaning of culturally relational education as co-researchers alongside the community councillors, school staff, and children, we are seeking to honour meaningful engagements with Indigenous philosophies and knowledge systems as they are understood and lived by all in relation.Keywords: research; mathematics education; culturally relational education; Indigenous philosophy; Indigenous knowledge
Exploring the Experiences of a Small Group of Saskatchewan Neophyte Aboriginal Teachers
Authors: Hellsten Laurie-ann M. , Preston Jane P. , Prytula Michelle P. , Jeancart Danielle P. 
Published: April 2021

The purpose of this paper is to explore the experiences of a small group of Aboriginal neophyte teachers in Saskatchewan, Canada. Part of a larger study, this research used a mixed method approach for data collection in which 18 Aboriginal beginning teachers completed a survey (with Likert-scale items and open-ended questions) and an additional two Aboriginal beginning teachers participated in individual interviews. This study is a focused attempt to highlight the voices of the Aboriginal beginning teachers. Findings suggested that many participants had difficulty obtaining employment and identified family and friends as their core supports. Most participants felt challenged by their workload and a lack of supports to address the diverse needs of their students. Most participants found teaching to be rewarding and enjoyed the autonomy of their own classrooms. Many of the issues raised by the participants can be addressed by placing a greater focus on an Aboriginal epistemology based on the concept of community. To promote Aboriginal teacher recruitment, employment, and retention rates, it is essential that neophyte teachers are provided with employment assistance, mentorship opportunities, and curricular and unit plan resources. Keywords: neophyte/beginning teachers; preservice teacher education, mixed-methodology
Inner Landscapes: Transformative Learning Experiences of Canadian Education Interns in Greece
Authors: Polyzoi Eleoussa , Magro Karen 
Published: April 2021

This exploratory study uses transformative learning theory as a lens to interpret and understand the challenges and successes experienced by education students who elect to teach or intern abroad. Transformative learning is a deeper-level learning that challenges learners to understand themselves and their world in new, more nuanced ways. We explore frames of teaching and learning from multiple lenses. Elements of the educational internship experience that emerged from students who participated in this study include initial apprehension, disbelief, and even fear; a disorienting dilemma or incongruent experience within the new school cultural context; a re-evaluation of their frames of reference, and a final emergence of more integrative, inclusive senses of self as “teacher” and “learner.” Transformative learning theory can serve both as a conceptual framework for understanding the experiences of students and as a means of suggesting ways in which educational outcomes can be better designed with a transformative intent in mind. We then present implications for teaching and learning and suggestions for future studies.

Applying First Nations Holistic Lifelong Learning to the Study of Crime
Authors: Anuik Jonathan 
Published: April 2021

Since the 1970s, critics have asked universities to “do more” to support Indigenous learners and learning. Universities usually respond by increasing Indigenous student and faculty representation on campuses and adding on units with Indigenous content in existing courses. However, a lot of curriculum and pedagogy remains vacant of Indigenous understandings of learning and perspectives on higher education content and topics for discussion. This paper applies epistemological lessons in the First Nations Holistic Lifelong Learning Model (2007) to the study of crime in America. Its inspiration comes from a guest lecture delivered by myself in an introductory sociology class. The students who take this class are registered in professional programs at a large private university in Rhode Island, United States. I describe the class’s context and use of the model with students in an engaged inquiry format to talk about the subject of the day: crime. This discussion can help faculty consider promising practices for grounding course content in Indigenous epistemologies. Keywords: Indigenous epistemologies; crime; higher education
The Relevance of Prior Learning in Teacher Education Admissions Processes
Authors: Hirschkorn Mark , Sears Alan , Sloat Elizabeth , Christou Theodore Michael , Kristmanson Paula , Lemisko Lynn 
Published: April 2021

In this paper, we argue that teacher education admissions processes would benefit from attending more to prospective teacher candidates’ cognitive frames. We begin with the introduction of a three-stage heuristic for describing teacher education. We then review the literature about constructivist notions of prior learning and teacher education program admissions processes. These processes, we argue, fail to adequately account for candidates’ preconceptions about teaching and learning, which affect their beliefs and understanding. Virtually none of the admissions processes we examined explicitly attempts to map the cognitive frames of applicants to uncover the structure of their ideas about teaching and learning. Teacher education institutions might best concentrate upon candidates’ cognitive frames within two core areas: subject area content knowledge and pedagogical knowledge. These two areas have the greatest potential to influence candidates’ future cognitive frameworks, understandings, and points of reference. Keywords: teacher education admissions processes; identifying cognitive frames; subject area content knowledge; pedagogical knowledge
Story as a Means of Engaging Public Educators and Indigenous Students
Authors: Moon Martha 
Published: April 2021

Two concerns in public Indigenous education are the education of teachers and the engagement of students. In this study, drawing on stories and multiple perspectives is an approach presented to address both concerns. In open-ended interviews with seven Indigenous educators and leaders in urban public school boards, story was highlighted as a central component of the success of Indigenous students. Participants believed that educators’ understanding and teaching practice is enriched by seeking out stories and multiple perspectives—those of Indigenous students and their families and communities in particular. They also believed that when these stories are valued in school, students’ sense of belonging and engagement increase. This paper explores various angles on drawing on stories in public schools as modes of engagement and learning for both educators and students. These angles address the experiences that students, teachers, and families bring to schools and the stories tied to local communities and embedded in Canadian school systems.
Teaching for Civil Society in Finland: A Canadian Perspective on Finnish Educators' Reflections
Authors: Orlowski Paul 
Published: April 2021

This article describes a study that took place in Helsinki, Finland in late 2015. A Canadian education professor conducted individual interviews with Finnish educators: six practicing teachers in Helsinki schools, two education professors at the University of Helsinki, and the advisor to the president of Finland’s teachers’ union. Although all five Nordic countries are known to support the social welfare state, Finland was chosen because it is considered to be the most economically left. The study is an exploration of how Finnish educators consider their role and the role of the school regarding civil society and the commons in Finland. The actual research question for the study was, “How do Finnish educators think about the school’s role in supporting the commons and in fostering social cohesion with immigration?” The nine participants were unanimous in their support of the commons and Finland’s generous social welfare state, apparently the result of a collectivist mentality in Finnish society. However, there appears to be growing social, economic, and political discrimination for immigrants and refugees who look different from White Finns. The six teacher-participants expressed uncertainty around how best to deal with these tensions, and were committed to attempting neutrality in their teaching of these social problems, or perhaps even ignoring them altogether. Despite the small sample set, I believe it represents a cross section of views of educators in contemporary Finland. Recent studies mentioned in the literature review support this position. Some comparisons with similar studies in Canada are briefly mentioned. Keywords: teaching for social justice; comparative education; Finnish education; controversial issues; Nordic social democracy.
