Required Materials: Edmodo account Laptop or other personal computer device with Java software downloaded (required for every session) Attendance Policy: Participants are expected to arrive on time and to participate in all classes as scheduled. If a participant is absent from a class session, she/he is still responsible for completing the class work and homework assigned for every session. In order to receive credit, participants can only miss five hours of instruction total, the equivalent of two class sessions. For participants who arrive late, the amount of time missed, rounded up to the nearest half hour, will be included in their missed session time. Homework: Every topic will be explained via video podcasts and demonstrations uploaded to the Edmodo class site. Before attending a class, participants are responsible for viewing all materials posted online and coming to class prepared with questions, or emailing the facilitators ahead of time to address questions. The in-class portion will be focused on reinforcing and building on the concepts covered in the podcasts and videos through hands-on activities and discussions. At the conclusion of every class, a homework assignment will be explained and posted on the Edmodo class site. This assignment should be completed independently by the following class period. Grading: All homework assignments will be scored according to the points shown in the table below. A minimum score of 7/10 is required in each of the assignments to earn credit for the course. If a participant earns less than 7/10 on any homework assignment, he/she has until the next session to improve and re-submit it for grading. 4 Effort and Completion Usage of Scientific Vocabulary Evidence of Scientific Reasoning and Logic Applied to Reponses Exceptional evidence of scientific reasoning and/or logic in response 3 Good effort is evident on assignment and assignment was fully completed Scientific vocabulary was used throughout response and was used correctly 2 Effort is evident on assignment but it was only partially completed Adequate evidence of scientific reasoning and/or logic in response Some evidence of scientific reasoning and/or logic in response Some scientific vocabulary was used in response and most was used correctly 1 Minimal effort was given on assignment and/or assignment was not fully completed Minimal scientific vocabulary used in response and/or vocabulary was used incorrectly Minimal evidence of scientific reasoning and/or logic in response SABES is supported by the National Science Foundation under Grant No. DUE-1237992. 0 Insufficient evidence of effort and/or assignment was not completed No scientific vocabulary used in response or vocabulary was used incorrectly No evidence of scientific reasoning and/or logic in response During each class, each participant will be issued a “participation grade” based on his/her engagement in the work. This means that participants should be on task at all times, and all side conversations and use of technology (i.e. cell phones/tablets) should be at a minimum, or not occur at all. A pre/post assessment is used for data purposes only. The assessment contains information covered both in class and in the podcast videos that will be used during sessions. There will be no graded quizzes, exams or projects. Three AUs and three CPD MSDE credits will be awarded for the successful completion of the course. Successful completion will be evaluated based on session attendance, homework grades, evidence of the podcasts’ viewing, and participation grades. Statement of Academic Continuity: Please note that in the event of weather and/or in other extraordinary circumstances, the School of Education may change the normal academic schedule and/or make appropriate changes to course structure, format, and delivery. In the event such changes become necessary, information will be posted on the Edmodo site. SABES is supported by the National Science Foundation under Grant No. DUE-1237992.
