Introduction

Concerns have arisen about the effectiveness of online graduate programs compared to more traditional approaches in higher education settings. This research study investigated the effectiveness of an online Educational Technology Leadership (ETL) master’s program to advance graduates’ leadership in the use of online learning, Web 2.0 tools, and technology professional development in PK-12 schools. A review of the literature indicated agreement that leadership is vital to continuous school improvement, and the quality of teachers directly impacts PK-12 student learning (Podmostko, 2001). Furthermore, building the leadership of technology using teachers appeared to be of significant interest to ensure all PK-12 students receive high quality instruction using 21st century technology tools. Moreover, graduates expressed interest in expanded career options in leadership roles as administrators, district technology coordinators, and technology professional development providers.

Background and literature review

Educational leadership has been a critical component to providing an environment conducive to effective teaching and learning. Candidates in an Educational Technology Leadership master’s program were provided with the leadership skills necessary to implement changes required for 21st century teaching and learning. These change leaders learned how to determine the procedures and processes that create the conditions necessary for organizational improvement. The literature relevant to this study included educational leadership with a focus on teacher leadership to administrative leadership, the use of online learning for personal learning and student learning, the use of Web 2.0 tools for teaching and learning, and the use of effective professional development for changing professional practices.

Educational leadership

Possibly, the most important single factor of an effective learning environment has been educational leadership (Daugherty, Kelley,&Thornton, 2005). Second only to quality curriculum and teacher instruction, leadership has been considered important in student learning (Leithwood&Riehl, 2003). Change leaders must have determined the procedures and processes that created the conditions necessary for organizational improvement. In addition, skillful leaders had a shared responsibility to provide vision for future needs and empowered others to share and operationalize the vision (Daugherty, et al.; Leithwood&Riehl, 2003). Historically, school districts have continually struggled to attract and retain highly qualified candidates for leadership roles (Knapp, Copland&Talbert, 2003). According to Leithwood and Riehl (2003), a current approach was to share leadership between administrators and teacher leaders. Administrators offered a more formal approach to leadership, while teacher leaders presented an informal approach. Glendinning (2005) reported that schools sought leaders who understood teaching and learning. Since classroom teachers routinely possessed those skills, it made sense that administrators tended to evolve from those classroom teachers. With the nearly 40% of principals’ positions that became vacant in 2010, it became crucial for schools to invest in the leadership capacity of their teachers (Ballek, O’Rourke, Provenzanom&Bellamy, 2005).

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
