professional development (TPD) is necessary. In the past 20years, many teachers have experienced TPD in engineering2. However, for most teachers, it hasbeen a one-time opportunity because engineering is not a required subject to be taught in class inmany states and lack of funding limited continuous support for teachers after their initialengineering TPD2.TPD is designed to change teachers’ attitudes, beliefs, and perceptions, so such changes areexpected to influence teachers’ classroom practices and result in improved student learning3,4.However, one-time TPD is not enough to achieve desired teacher change because (a) changingpractice requires prolonged engagement with a new practice, (b) it might be hard for teachers tomake an immediate change after

Due to low sample sizes (from lowresponse rates per survey item), this study takes a more qualitative approach to analyzing thesurvey responses. Survey response data were grouped by grade band. Frequencies of categoricalresponse data from the surveys were totaled for each band. Standardized frequencies (proportionof code frequency for a grade band) of responses were compared between bands.8. ResultsMany different dimensions were analyzed from the survey responses.

Formative assessment refers to all the activities undertaken by teachers and bytheir students in assessing themselves to provide information to be used as feedback to modifyteaching and learning activities. (Black, 1998) Three main problems about assessments arepointed out in the article named “Working inside the black box: Assessment for learning in the Page 24.591.3classroom” (Black, 2004): a. the assessment methods that teachers use are not effective inpromoting good learning; b. grading practices tend to emphasize competition rather thanpersonal improvement; c. assessment feedback often has a negative impact

The DIB contains circuits that will allow the DUT to beplaced into different configurations for different specification tests (e.g. input bias current, offsetvoltage, linearity, propagation delay, etc.). The DIB circuits may be as simple as load structures(output resistors and/or capacitors) or input resistors to gain up input current measurements, or ascomplicated as negative feedback servo-loops to force the device into a known state.
