4 The Classes CHE 111 General Chemistry I Lab Accmpanies CHE 105 (the lecture), CHE 105 is a pre-requisite/creq. Deals with the prperties f chemical substances and prvides an intrductin t quantitative chemical analysis Intrduces students t basic labratry techniques Teaches students t write lab reprts CHE 113 General Chemistry II Lab Accmpanies CHE 107 (the lecture), CHE 107 is a pre-requisite/creq. CHE 105 is a pre-requisite Emphasizes qualitative and quantitative chemical analysis Mre in depth analysis Students expected t apply knwledge gained in 111

UK Cre Required Curse General Educatin Prgram Gal is t braden students understanding f themselves, the wrld we live in, their rle in ur glbal sciety, and the ideals and aspiratins that have mtivated human thught and actin thrughut the ages. Learning Outcmes Demnstrate understanding f & ability t emply the prcess f intellectual inquiry Demnstrate cmpetent written, ral, and visual cmmunicatin skills bth as prduces and cnsumers f infrmatin. Demnstrate an understanding f and ability t emply methds f quantitative reasning. Demnstrate an understanding f the cmplexities f citizenship and the prcess fr making infrmed chices as engaged citizens in a diverse, multilingual wrld. Must take CHE 105 & 111 t earn UK Cre credit.

17 Changes t the Lab Manual Lab readings based upn idea f students wrking at a chemical facility. Build idea that they are part f a cmmunity f practice (aka they will be getting a jb sme day). Labs set up a prblem that they are trying t slve. Help students identify when they need a hypthesis versus a gal

21 Blm s Taxnmy Cmbining infrmatin t frm a unique prduct; requires creativity and riginality. Using infrmatin t slve prblems; transferring abstract r theretical ideas t practical situatins. Identifying cnnectins and relatinships and hw they apply. Memrizing verbatim infrmatin. Being able t remember, but nt necessarily fully understanding the material. Evaluatin Synthesis Analysis Applicatin Cmprehensin Knwledge This pyramid depicts the different levels f thinking we use when learning. Ntice hw each level builds n the fundatin that precedes it. It is required that we learn the lwer levels befre we can effectively use the skills abve. Making decisins and supprting views; requires understanding f values. Identifying cmpnents; determining arrangement, lgic, and semantics. Restating in yur wn wrds; paraphrasing, summarizing, translating.

23 Syllabus / Schedule In yur grups, read the curse schedule and discuss amngst yurselves the curse plicies & class schedules fr bth CHE 111 & 113. Be prepared t present sectins frm the syllabus as yu wuld n the first day f lab t yur students.

24 Leading a Lab Sectin (Part 1) Split int grups f 2 cnsisting f 1 mentr TA and 1 mentee TA. Select an experiment frm CHE 111 r 113 and have the mentr TA teach it t the ther TA. Discuss the chemistry invlved in the lab, hw t use equipment in the lab, and cmmn student prblems. Make sure yu as the mentr TA knw any changes made frm prir semesters and incrprate them int yur teaching experience.

25 Leading a Lab Sectin (Part 2) In frnt f the class, each mentee TA will teach us abut their experiment, based upn the knwledge acquired frm their mentr TA. The class is expected t ask the presenter questins like their students in lab.
