As assistive technology applications are increasingly implemented in early childhood settings for children who are at risk
or who have disabilities, it is critical that teachers utilize observational approaches to determine whether targeted assistive
technology-supported interventions make a difference in children’s learning. One structured strategy that employs observations
and which has powerful child progress monitoring implications is the concurrent time series probe approach. Requiring multiple
performance measures of a child engaged in a targeted task over time—both with and without a specific assistive technology
device—the concurrent time series probe approach can be used to evaluate the effectiveness of assistive technology tools in
supporting skill acquisition in the classroom. This approach is described in the context of a case study, with accompanying
explanations of how to interpret data and make decisions regarding the effectiveness of the technology. 相似文献

As many primary pre-service teachers enter teacher education courses with little science background, it is essential in teacher education courses to provide opportunities for them to learn more science independently. The purpose of this study is to investigate an online pedagogical activity that fosters the social construction of science knowledge by primary pre-service teachers working in small virtual teams. The study investigated how the pre-service teachers collaborated online in virtual teams to complete set tasks, their attitudes toward and beliefs about the effectiveness of the online learning experience, and the types and quality of the resources developed. The findings indicated that the virtual team-produced science resource materials were generally of high quality, with nearly half the number of teams engaging with Web 2.0 technologies (e.g. wikis and blogs) to construct their product. The findings indicated positive attitudes toward the collaborative learning even though beliefs about online learning were mixed. 相似文献

This paper asks what is necessary in a theory of science adequate to the task of empowering philosophers of science to participate
in public debate about science in a social context. It is argued that an adequate theory of science must be capable of theorizing
the role of values and motives in science and that it must take seriously the irreducibly social nature of scientific knowledge.

It is time to situate distributed leadership as a critical conceptualisation of school leadership; its popularisation has generally preceded conceptual and empirical development. Over the last 10 years distributed leadership has often been presented as a new construct of school leadership, though critique against education policy reforms and conceptual and historical links to the wider leadership field have generally been underemphasised. The theorisation and research of distributed leadership is currently situated at a critical point in its development; it is at the ‘crossroads’ of where it could dominantly be situated in the field of school leadership. A review of the literature and research suggests that distributed leadership is tending towards an uncritical position that is decoupled from critique of past and present education reforms and predominantly silent on how power relations at the local school level shape leadership activity. 相似文献

In the current shifts in mathematics classrooms, teachers are challenged to use effective pedagogy to develop inquiry communities
in which all participants are offered opportunities to engage in the reasoning discourse of proficient mathematical practices.
The challenge for teachers is to know how to implement these pedagogical changes. This article outlines how a teacher and
researcher worked together in a collaborative partnership using a purposely designed communication and participation framework
as a tool to scaffold development of collective reasoning in the inquiry community. The findings illustrate the interconnections
between the teacher’s beliefs, past experiences, and current, and future expectations for her diverse students. Explanations
are provided of how different, often conflicting, voices emerged including one that drew on the teacher’s cultural knowledge.
This provided many learning opportunities for the researcher as the teacher developed her students’ voices in culturally appropriate
ways. 相似文献

Practicums, internships and field experiences are essential components in many fields. These varied experiences embed both students and their mentors in immersive experiences. Such immersive experiences are essential for STEM students preparing for future jobs, yet little is known about how these research-intensive and immersive experiences impact the practice of teaching in the natural sciences. In order to evaluate the impact, opportunities and challenges associated with such experiences, our team collected and analysed end-of-semester reflections from five students and their faculty mentor. Thematic analysis related to inferences and implications about the impacts of the experience showed a need to formalize and further develop an understanding of both students’ self-identity and the cultural attitudes of the students and the mentor. 相似文献

A substantial amount of professional development and implementation has moved towards teachers and teacher leaders in recent years. Previous works have examined how teachers, teacher leaders, or administrators perceive teacher leadership in school reforms, but few have advanced all three perspectives simultaneously. Drawing upon over 200 interviews, we examine how leadership is distributed and the tensions and dynamics arising among these three groups in a teacher-led school reform. Two main themes emerged from our analysis: minimizing conflicts with teachers was important to teacher leaders, and the distribution of leadership between administrators and teacher leaders changed the status and normative roles of teacher leaders. 相似文献

Abstract The purpose of this study was to assess the agreement between two mobile cycle ergometer systems for recording high-intensity, intermittent power output. Twelve trained male cyclists (age 31.4 ± 9.8 years) performed a single 3 min intermittent cycle test consisting of 12 all-out efforts, separated by periods of passive recovery ranging from 5 to 15 s. Power output was recorded using a Polar S710 heart rate monitor and power sensor kit and an SRM Powercrank system for each test. The SRM used torque and angular velocity to calculate power, while the S710 used chain speed and vibration to calculate power. Significant differences (P < 0.05) in power were found at 8 of the 12 efforts. A significant difference (P = 0.001) was also found when power was averaged over all 12 intervals. Mean power was 556 ± 102 W and 446 ± 61 W for the SRM and S710 respectively. The S710 underestimated power by an average of 23% with random errors of ?/÷ 24% when compared with the SRM. Random errors ranged from 36% to 141% with a median of 51%. The results indicate there was little agreement between the two systems and that the Polar S710 did not provide a valid measure of power during intermittent cycling activity when compared with the SRM. Power recorded by the S710 system was influenced greatly by chain vibration and sampling rates. 相似文献
