Digital Electronics Course Objectives

Transcription

1 Digital Electronics Course Objectives In this course, we learning is reported using Standards Referenced Reporting (SRR). SRR seeks to provide students with grades that are consistent, are accurate, and most importantly, reflect learning. Student work is evaluated on evidence of learning; not on completion, timeliness, or behavior. Students performance will be based on their achievement in specific learning objectives. Every objective will be evaluated individually for proficiency. Each objective will be reported as Beginning, Developing, Secure, or Exceeds. The objectives in this course are listed below by unit. The universal course objectives will be continuously instructed on and assessed throughout the entire semester. The College and Career Readiness (CCRS) standards will be evaluated regularly throughout the semester as well, however, they will not impact student grades. Proficiency Level Beginning Developing Secure Exceeds Indicator BG DV S E Descriptor Student has currently demonstrated little understanding.
