Résumé
As a follow-up to our previous paper on the successes and limitations of using Rube Goldberg machines in a first year engineering design course, in this paper, we outline how we addressed some of the limitations from our first attempt to use Rube Goldberg machines in our course.As pointed out in our previous paper, the first year engineering curriculums of many engineering programs are heavily loaded with science classes and have very little exposure to engineering.Engineering schools must find ways to introduce students to engineering in a fun, engaging fashion.For the past two years, we have been using Rube Goldberg machines to help achieve this goal.Our first year design and communications course attempts to engage students by challenging them to design and build a working Rube Goldberg machine as part of a group project.By working to achieve specific design goals that are subject to constraints, students get to work on a miniengineering project that is fun, creative, and challenging.The long-term goal of the Rube Goldberg Experiment is twofold: (1) to give first year engineering students a positive engineering design experience in their very first semester and (2) to develop a culture of anticipation in Grade 12 students who might be considering an engineering education at the University of Regina.In this paper, we outline changes made to our approach that address shortcomings identified from our first semester and provide results from student feedback, which demonstrate a positive response to the project.Table 1.ENGG 123 Rube Goldberg Projects -Fall 2009 Theme 1 Indiana Jones Primary Task Rescue Indy's hat.Start Action Replace a Golden Idol with a bag of sand.Sub-Goals• Indy escapes from a giant rolling boulder.• Tribal warriors shoot five poisoned darts at Indy (a distance of 50 cm).• The Ark opens and destroys the Nazis.• Indy falls into a pit of snakes and escapes.• Kill a bad guy with a plane propeller.• Indy shoots a cocky swordsman.Theme 2Winter Olympics Primary Task Raise a Canadian flag and play the national anthem. Start ActionLight the Olympic flame.Sub-Goals• Send a bobsled down a track with at least three 90° curves.• Bury a Loonie under the arena ice.• Launch a ski jumper 100 cm.• Curl a rock to the button down the ice (a distance of 50 cm).• Shoot at least three of five biathlon targets.• Hang a gold medal around a Canadian athlete's neck.Theme 3Harry Potter Primary Task Catch the Snitch (the Snitch must fly 50 cm).

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
