Impact of Robotics and Geospatial Technology Interventions on Youth STEM Learning and Attitudes

Abstract This study examined the impact of robotics and geospatial technologies interventions on middle school youth’s learning of and attitudes toward science, technology, engineering, and mathematics (STEM). Two interventions were tested. The first was a 40-hour intensive robotics/GPS/GIS summer camp; the second was a 3-hour event modeled on the camp experiences and intended to provide an introduction to these technologies. Results showed that the longer intervention led to significantly greater learning than a control group not receiving the instruction, whereas the short-term intervention primarily impacted youth attitude and motivation. Although the short-term intervention did not have the learning advantages of a more intensive robotics camp, it can serve a key role in getting youth excited about technology and encouraging them to seek out additional opportunities to explore topics in greater detail, which can result in improved learning.

TPACK Development in Teacher Education: A Longitudinal Study of Preservice Teachers in a Secondary M.A.Ed. Program

Abstract How does preservice teachers’ knowledge for technology integration develop during their teacher preparation program? Which areas of their knowledge develop most naturally, and which areas require more scaffolding? In this mixed-methods, descriptive study of preservice teachers enrolled in an 11-month M.A.Ed. program, we sought to trace the development of participants’ technological pedagogical content knowledge (TPACK) over time. Comparisons of self-report surveys, structured reflections, and instructional plans at multiple data points spanning the three-semester program revealed significant development of the participants technological pedagogical knowledge (TPK) and technological pedagogical content knowledge (TPACK), but only limited growth in technological content knowledge (TCK).

Correlates among Teachers' Anxieties, Demographics, and Telecomputing Activity.

AbstractAre educators’ anxiety levels or demographics related to their voluntary use of networked resources? In this study, one year of logins and online time for 189 randomly selected educators with accounts on Tenet (Texas Education Network) were correlated with six interval-level subject attribute variables: (a) writing apprehension, (b) oral communication apprehension, (c) computer anxiety, (d) age, (e) teaching experience, and (f) telecomputing experience. The usage data were also correlated with three nominal-level subject attribute variables: (a) gender, (b) professional specialty, and (c) teaching level. Results indicated that writing apprehension was significantly and negatively correlated with network use, and that telecomputing experience and online time were significantly and positively correlated. No other subject attribute variables were found to be correlated with logins or time spent online. These results, and the lack of significant relationships for computer anxiety and oral communicatio...

Correlates with Use of Telecomputing Tools: K-12 Teachers' Beliefs and Demographics

AbstractWhat can be determined about the demographic characteristics, beliefs about teaching, degrees of innovativeness, and world views of classroom teachers and specialists who use Internet-based telecomputing tools? This study correlated data representing a year of online use with responses to questionnaire items about teacher beliefs and demographics for 558 respondents from a sample of 1,000 randomly selected Internet account holders on TENET, the statewide K–12 educational telecomputing network in Texas. Results showed significant correlations among beliefs about teaching, personal perceptions of innovativeness, and world views; respondents who were more student-centered in their beliefs about teaching perceived themselves to be more innovative and tended to see the world in a more social constructivist way than respondents with more traditional beliefs about teaching. Yet no strong significant correlations between telecomputing activity and beliefs or demographic information were found. In the case...

Identification of the Emergent Leaders within a CSE Professional Development Program

The need for high quality, sustainable Computer Science Education (CSE) professional development (PD) at the grades K-12 level is essential to the success of the global CSE initiatives. This study investigates the use of Social Network Analysis (SNA) to identify emergent teacher leaders within a high quality CSE PD program. The CSE PD program was designed and implemented through collaboration between the computer science and teacher education units at a Midwestern metropolitan university in North America. A unique feature of this specific program is in the intentional development of a social network. This study discusses the importance of social networks, the development of social capital, and its impact on the sustainability of the goals of the CSE PD program. The role of emergent teacher leaders in the development of the social capital of the CSE PD cohort is investigated using SNA techniques. The cohort consisted of 16 in-service teachers in grades 6-12 representing seven districts and four distinct content areas. The instruments used involved a questionnaire and the results of a CSE PD program online course. The findings suggest a correlation between the emergent teacher leaders, the online course results, and the overall cohort social capital. Future uses of SNA within professional development programs are also discussed.

How do undergraduate STEM mentors reflect upon their mentoring experiences in an outreach program engaging K-8 youth?

BackgroundMany university students are becoming involved in mentoring programs, yet few studies describe the impact of mentoring on the mentor. Additionally, many studies report that students graduating from college are not prepared to enter the workforce in terms of key career skills and/or content knowledge. Herein, we examine the impact of our program, NE STEM 4U (Nebraska Science, Technology, Engineering and Math for You), in which undergraduate (UG) mentors engage K-8 youth in after-school STEM experiments. The UGs reflected upon their experiences using post-mentoring evaluations, 12- and 24-week interviews, and exit surveys. Many of the questions asked of the mentors related directly to their own professional development, such as self-evaluation of communication, organization, and problem-solving skills, while other questions related to content knowledge and reflection.ResultsPost-mentoring, UGs reflected on the delivery/teaching significantly more (pu2009≤u20090.001 for each) than other variables (i.e., their own content knowledge gains, the students’ content knowledge gains, scaffolding the lessons, or overall professional growth). By analyzing the evaluations and interviews together, some significant, self-reported gains emerged. For example, 94.15% of the UG reported that the experience was beneficial to their education. Additionally, UG mentors self-reported significant gains (pu2009≤u20090.01 for each) moving from 12- to 24-weeks in the program in the categories of organization, STEM content knowledge, preparedness to teach, and engagement in the program. However, UG did not report significant gains in dependability. Importantly, when mentors ranked themselves at 24-weeks, they were blinded to (unaware of) the ranking they gave themselves at 12-weeks.ConclusionsThis study helps to fill a gap in the literature by providing insight into the gains UG mentors report attaining after mentoring to K-8 students. These data suggest that participation by UGs in this program promoted self-reflection as well as self-reported gains related to career preparedness and STEM content knowledge.
