Case:

Maths achievement is a significant problem in School District A. According to recent figures, approximately 47% of the Year 7 students in District A are underperforming on state mandated Year 7 end of year maths tests. In response to this issue, and as part of a wider ‘Maths Matters’ state initiative involving a variety of maths programs (e.g., increased time devoted to maths by 15 minutes per day throughout the primary school years; provision of free take-home maths support materials; facilitation of after-school maths clubs; and organisation of community maths fairs), School District A implemented a new maths curriculum software program in four Year 7 schools in order to increase students’ maths achievement. The pilot maths curriculum software program was implemented from March 2015 to April 2016. The stated aim of the program was to increase maths achievement on the state-mandated, Year 7 end of year test by 10% and increase in student self-efficacy. An extensive impact evaluation was conducted by the overseas company who designed the software. The methodology incorporated a utilization-focused approach and involved:

  •   The establishment of a steering committee involving key stakeholders
  •   Site visits to the four schools where the maths curriculum software program was implemented
  •   A comprehensive before-after examination of school statistics on maths achievement in the school the 
year before implementation compared to the year after
  •   A total of 1,000 telephone surveys of district parents conducted during the day to assess parent reports of their child’s satisfaction with maths.

 

  • Results suggest that the maths curriculum software program was extremely effective in meeting its goals— district maths achievement increased by 30% and statistical analysis of the survey revealed a high level of satisfaction with maths.
  • 
However, the steering committee is concerned that the design might not have been appropriate. Before expanding the program to other schools, they consult you a research expert and request advice on how the research design could be improved.

  Reflection Students are encouraged to create portfolios and begin to "manage" their careers. When you began a college education you took the first step. You now need to begin to reflect on the next goal, then medium, and long-term goals. I did not complete my final degree until well into my 50's. And that is fine, I loved my health care career. I was eager to care for patients and did not leave direct patient care for many decades. I did know the time would come to do so however, and began to earn the college degrees I would need at the proper time. This is what is meant by managing your career. This is an entry level program. It is designed to assist you in getting your "foot in the door" where you can learn valuable clinical skills. A common and important degree is the Bachelor of Health Information Management (BS-HIM).
