The Human Nervous System: A Framework for Teaching and the Teaching Brain     

Vanessa Rodriguez 《Mind, Brain, and Education》2013,7(1):2-12

The teaching brain is a new concept that mirrors the complex, dynamic, and context‐dependent nature of the learning brain. In this article, I use the structure of the human nervous system and its sensing, processing, and responding components as a framework for a re‐conceptualized teaching system. This teaching system is capable of responses on an instinctual level (e.g., spinal cord teaching) as well as higher order student‐centered teaching and even more complex teaching brain teaching. At the most complex level the teacher and student engage in a synchronistic teaching flow that achieves the optimal teaching and learning experience.  相似文献   

School Administrators and Educational Technologies: narrowing the divide     

Donn Ritchie  Stephen Rodriguez 《Technology, Pedagogy and Education》2013,22(1-2):107-114

ABSTRACT

Technologies that enhance classroom instruction and school administration are widespread. The majority of schools, however, have yet to implement technologies beyond a basic level. Reasons for this reluctance include a lack of funds, teacher beliefs about the role of technology in education, methods of technology allocation and distribution in schools, a lack of understanding of how technologies can accentuate learning and administration, and most importantly, a lack of vision and support from school administrators. To help solve the problem of administrative support, we propose the creation of university courses designed to nourish school technology leaders. Included in this paper is a basic outline for such a course.  相似文献

Assessing the impact of a university teaching development programme     

Keith Trigwell  Katia Caballero Rodriguez  Feifei Han 《Assessment & Evaluation in Higher Education》2012,37(4):499-511

Four different indicators are used to assess the impact of a year‐long university teaching development programme in an Australian research‐led university. All four indicators show small positive outcomes. Teachers who complete the programme have higher rates of receipt of teaching awards and teaching development grants than their colleagues who do not participate in the programme. Students in the classes of teachers who complete the programme report, on average, higher satisfaction scores than students in the classes of the same teacher before she/he completed the programme. Students in the faculties where the programme is completed by a higher proportion of academic staff report greater change to levels of satisfaction in the quality of their degree over the seven‐year period of the study. The methodology adopted involves several new approaches to evaluation and confirms the need for the use of an evaluation framework and multi‐indicator strategy.  相似文献   

Pathway Towards Fluency: Using ‘disaggregate instruction’ to promote science literacy     

Bryan A. Brown  Kihyun Ryoo  Jamie Rodriguez 《International Journal of Science Education》2013,35(11):1465-1493

This study examines the impact of Disaggregate Instruction on students’ science learning. Disaggregate Instruction is the idea that science teaching and learning can be separated into conceptual and discursive components. Using randomly assigned experimental and control groups, 49 fifth‐grade students received web‐based science lessons on photosynthesis using our experimental approach. We supplemented quantitative statistical comparisons of students’ performance on pre‐ and post‐test questions (multiple choice and short answer) with a qualitative analysis of students’ post‐test interviews. The results revealed that students in the experimental group outscored their control group counterparts across all measures. In addition, students taught using the experimental method demonstrated an improved ability to write using scientific language as well as an improved ability to provide oral explanations using scientific language. This study has important implications for how science educators can prepare teachers to teach diverse student populations.  相似文献   

Psychometric Considerations for Alternate Assessments Based on Modified Academic Achievement Standards     

Michael C. Rodriguez 《Peabody Journal of Education》2013,88(4):595-602

Because of the unique nature of the students eligible for alternate assessments based on modified academic achievement standards, their varied access to the general education curriculum, and their unique learning needs, innovative psychometric thinking and practice is needed to assure high technical quality of alternate assessments. Indeed, we at least must marshal state-of-the-art procedures to secure strong psychometric evidence to support appropriate and meaningful design and use of these important assessments. The authors contributing work to this special issue, Alternate Assessments Based on Modified Academic Achievement Standards, address important issues and provide guidance to policymakers, test developers, and educators. They also each raise important technical quality issues. This article offers a brief review of such psychometric considerations, in light of the work and comments of the special issue authors.  相似文献   

‘Where do I go from here?’: learning to become activist teachers through a community of practice     

Kimberly L. Oliver  Carla Luguetti  Raquel Aranda  Oscar Nuñez Enriquez  Ana-Alycia Rodriguez 《Physical Education & Sport Pedagogy》2018,23(2):150-165

Background: Student-Centered Inquiry as Curriculum (SCIC) is an activist approach [Oliver, K. L., and H. A. Oesterreich. 2013. Student-Centered Inquiry as Curriculum as a Model for Field-Based Teacher Education. Journal of Curriculum Studies 45 (3): 394–417. doi:10.1080/00220272.2012.719550] inspired by years of research with youth. It was designed as a means of listening and responding to youth in order to better facilitate students’ interest, motivation, and learning in physical education settings. While we have a strong and growing body of activist research with youth in physical education, SCIC as a specific approach to working with youth is in its infancy; thus, there is a need to further explore the challenges teachers/researchers face learning to use this approach to teaching.

Purpose: This study explores how educators, in different contexts, learn to use an activist approach called SCIC, in order to better facilitate students’ interest, motivation, and learning in physical education and physical activity settings.

Research setting and participants: Participants included a university professor, a college instructor, a postdoctoral student, a doctoral student, and a pre-service teacher. Data were collected between January and May 2016.

Data collection and analysis: Data collection included weekly field notes and debriefings following observations, teacher artifacts, weekly collaborative group meetings, and two individual interviews per teaching participant.

Discussion and conclusions: The main challenge that emerged was learning how to move from a theoretical understanding of student-centered pedagogy to the practice of student-centered pedagogy. Specifically, the amount of time that was necessary to build a foundation that allowed for student and teacher understanding, respect, and comfort, negotiating teacher and student assumptions that were embedded in the status quo of physical education (PE), and the struggle to gather and use meaningful data to guide pedagogical decisions. We negotiated these challenges through our professional learning community whereby we worked to all be able to see and name what was happening in our individual classes and collectively planned what was needed to move forward through these challenges.  相似文献   

HIV knowledge and risk among Zambian adolescent and younger adolescent girls: challenges and solutions     

Stefani A. Butts  Annette Kayukwa  Jake Langlie  Violeta J. Rodriguez  Maria L. Alcaide  Ndashi Chitalu 《Sex education》2018,18(1):1-13

In sub-Saharan Africa, young women are at the highest risk of HIV infection. Comprehensive sexuality education and open parent–child communication about sex have been shown to mitigate risky sexual practices associated with HIV. This study aimed to identify sources of HIV prevention knowledge among young women aged 10–14 years and community-based strategies to enhance HIV prevention in Zambia. Focus group discussions were conducted with 114 young women in Zambian provinces with the highest rates (~20%) of HIV. Discussions were recorded, transcribed and coded, and addressed perceived HIV risk, knowledge and access to information. Participants reported that limited school-based sexuality education reduced opportunities to gain HIV prevention knowledge, and that cultural and traditional practices promoted negative attitudes regarding condom use. Parent–child communication about sex was perceived to be limited; parents were described as feeling it improper to discuss sex with their children. Initiatives to increase comprehensive sexuality education and stimulate parental communication about sexual behaviour were suggested by participants. Culturally tailored programmes to increase parent–child communication appear warranted. Community-based strategies aimed at enhancing protective sexual behaviour among those most at risk are essential.  相似文献
