Investigating The Relationship Between Empowerment And Secondary Science Teachers’ Technology Integration Knowledge, Jane Elizabeth Walsh

Theses and Dissertations--Educational Leadership Studies

Empowered teachers believe they can improve their work conditions and positively impact student outcomes. Likewise, teachers with technology integration knowledge can effectively use technology to enhance lessons and improve student learning. This quantitative correlational study investigated teachers’ empowerment, teachers’ technology integration knowledge, and associations between empowerment and technology integration knowledge. Two hundred fourteen randomly selected high school science teachers from across the United States responded to a survey intended to measure empowerment and technology integration knowledge. The teachers' average responses indicate that teachers generally agree with statements surrounding empowerment (M = 3.93, SD = 0.54) and technology integration knowledge …

The Perceptions And Usage Of The Interactive Video Playposit In A General Chemistry Course, Tracy Gastineau-Stevens

Theses and Dissertations--Education Sciences

Technology within science, technology, engineering, and mathematics (STEM) classrooms has been a topic of discussion for decades (Reiser, 2001, 2007). With the inclusion of more technologies or digital tools in the classroom has pushed classes towards a blended learning or flipped classroom approach (Atkins 2015; Tayebinik & Puteh, 2013; Williams et al., 2008). One such digital tool that has started gaining traction in the STEM classroom is the interactive video (M. K. Seery, 2013; Smith, 2013). Interactive videos allow students to watch the general lecture material outside of class and work through problems during normal class time (M. K. Seery, …

Developing Pedagogical Content Knowledge As Communal Practice: A Case Study Of Chemistry Graduate Teaching Assistants, Walker Bryan Mask

Theses and Dissertations--Education Sciences

Learning does not only happen during dedicated instructional time, which also applies to learning how to teach. Teachers can reflect on their practice while working to continue to improve and develop their teaching skills. In addition to self-reflection, teachers can also learn from their colleagues to experiment with new practices and take others’ teaching knowledge into their repertoire. Understanding how these two processes function can lead to developments in teacher education and professional development, specifically for initiatives that seek to promote collaboration among teachers. Post-secondary educators in particular can benefit from collaborative and reflective practices to improve their teaching, especially …

Nature Of Science: Examining Science Teachers’ Knowledge And Their Instructional Practices, Sharon Bramwell-Lalor

Australian Journal of Teacher Education

This case study focused on a university teacher-education course that included NOS content. An adapted questionnaire was used to collect quantitative data on 83 secondary science teachers’ views about three NOS themes before and after completing the course. Qualitative data were collected from eight of the teachers who were observed teaching during their field experience after completing the course. The teachers’ post-course mean NOS scores were statistically significantly higher than their pre-course scores (t (65) =-10.08, p<.001; Cohen’s d = 1.4). Despite the favourable NOS knowledge among the science teachers, low levels of NOS portrayal were observed in their instructional practices. These findings point to some success in explicitly addressing NOS in science education content courses. However, they raise questions about the transferability of teachers’ NOS knowledge into their classrooms. The findings have implications for teacher-preparation programmes regarding durability of NOS knowledge.

Girls and women face persistent negative stereotyping within STEM (science, technology, engineering, mathematics). This field intervention was designed to improve boys' perceptions of girls' STEM ability. Boys (N = 667; mostly White and East Asian) aged 9-15 years in Canadian STEM summer camps (2017-2019) had an intervention or control conversation with trained camp staff. The intervention was a multi-stage persuasive appeal: a values affirmation, an illustration of girls' ability in STEM, a personalized anecdote, and reflection. Control participants discussed general camp experiences. Boys who received the intervention (vs. control) had more positive perceptions of girls' STEM ability, d = 0.23, …

Accuracy Assessment Of The Ebee Using Rtk And Ppk Corrections Methods As A Function Of Distance To A Gnss Base Station, Joseph Cerreta, David Thirtyacre, Peter Miller, Scott S. Burgess, William J. Austin

International Journal of Aviation, Aeronautics, and Aerospace

The use of unmanned aircraft systems to collect data for photogrammetry models has grown significantly in recent years. The accuracy of a photogrammetric model can depend on image georeferencing. The distance from a reference base station can affect the accuracy of the results. Positioning corrections data relies on precise timing measurements of satellite signals. The signals travel through the Earth's atmosphere, which introduces errors due to ionospheric and tropospheric delays. The aim of this research was to examine the eBee X and its global GNSS accuracy by comparing the RTK and PPK methods at different base station distances in photogrammetry …

Overall, students who attended the clubs were African American (55%), female (56%), and 6th graders (42%), attended approximately half of the clubs (43%), and agreed with quality measures on the STEM Club Survey (M …

What Do Mathematics Lessons Look Like? Analyses Of Primary Students’ Drawings, Benjamin Rott, Laura Barton, Vesife Hatisaru

Research outputs 2022 to 2026

The use of student drawings to assess their experiences and beliefs about teaching and learning of mathematics has become almost a regular research method – especially when working with young students who may not express themselves well, for example, in self-report questionnaires. These methods, nevertheless, need to be improved regarding their objectivity and validity. By building on the existing research, in this study, we focus on objectivity and validity issues in drawing-based methods. We use a drawing-based instrument: Draw A Mathematics Classroom (DAMC) and present 104 fourth-grade students to draw a picture of their regular mathematics lessons. We especially aim …

How Teacher-Student Relationships Shape Student Engagement And Interest In Science, Destini N. Braxton

Theses and Dissertations

The current research on emotional engagement and teacher-student relationship is abundant and acknowledges education as an environment that thrives on social interactions and causes a variety of emotions to be present in the classroom. However, research on the relationship between Black and Latinx students’ teacher-student relationships and students’ emotional engagement and interest in science in urban middle school science classrooms remains scarce. Unfortunately, Black and Latinx students often experience a) mixed social interactions with their teachers, b) a lack of relatability to science instruction, and c) a combination of positive and negative emotions during science instruction and activities. This phenomenological, …
