We make Deal­ma­ker

Pro­fes­sio­nal nego­tia­ti­on is not some­thing you learn in school or at uni­ver­si­ty. The­r­e­fo­re, the nego­tia­ti­on trai­ning enables entre­pre­neurs and exe­cu­ti­ves to nego­tia­te con­fi­dent­ly and effi­ci­ent­ly.

To ensu­re that your nego­tia­ti­on trai­ning is always up to date, Prof. Dr. Jack Nas­her deals with nego­tia­ti­on prac­ti­ce and the fin­dings of inter­na­tio­nal rese­arch on a dai­ly basis.

Didac­tics — 5 pil­lars of lear­ning

The 5 lear­ning prin­ci­ples of the NAS­HER Nego­tia­ti­on Insti­tu­te

NAS­HER tea­ches accor­ding to the most effec­ti­ve tea­ching con­cepts in adult edu­ca­ti­on, accor­ding to the metho­do­lo­gy of con­s­truc­ti­vist didac­tics and acce­le­ra­ted lear­ning. We know how to cap­tu­re and hold par­ti­ci­pan­ts’ atten­ti­on, inspi­re them, and rein­force the con­tent in the long term.

1. lear­ning is not con­sump­ti­on, but crea­ti­on.

A lear­ner inte­gra­tes the new know­ledge and skills into exis­ting struc­tures. The­r­e­fo­re, a lear­ner must be actively enga­ged to app­ly the new know­ledge to his or her nego­tia­ti­on rea­li­ty — NAS­HER trai­ners are faci­li­ta­tors.

2. can, not know.

In school we learn things in iso­la­ti­on — we are able to pass tests, but not to app­ly the know­ledge in prac­ti­ce. The­re is a dif­fe­rence bet­ween kno­wing and being able to do. We learn to swim by swim­ming, to sing by sin­ging, and to nego­tia­te by nego­tia­ting. The real and the con­cre­te are bet­ter tea­chers than the hypo­the­ti­cal and the abs­tract. That’s why NAS­HER semi­nars often use simu­la­ti­ons and real-life examp­les.

3. lear­ning takes place on many levels simul­ta­neous­ly.

Child­ren learn by absor­bing many things at once; as adults, we are used to lear­ning only one item at a time in a line­ar fashion. Howe­ver, our brains are not sequen­ti­al pro­ces­sors but par­al­lel pro­ces­sors and thri­ve when chal­len­ged to do many things at once. The­r­e­fo­re, in NAS­HER trai­ning, par­ti­ci­pan­ts are chal­len­ged on many levels simul­ta­neous­ly (con­scious­ly and uncon­scious­ly, theo­re­ti­cal­ly and prac­ti­cal­ly) to use all pos­si­ble pathways.

4. posi­ti­ve emo­ti­ons impro­ve lear­ning enorm­ously.

Lear­ning that is stressful, pain­ful and bleak can­not hold a cand­le to lear­ning that is joyful, rela­xed and enga­ging. That’s why at NAS­HER we value respect, hones­ty and lots of humor. In fact, our semi­nars have been infu­sed with humor by come­dy wri­ters.

5. coope­ra­ti­on helps lear­ning.

A true com­mu­ni­ty of lear­ners is bet­ter for lear­ning than a coll­ec­tion of iso­la­ted indi­vi­du­als. A com­pe­ti­ti­ve atmo­sphe­re slows lear­ning. Even though NAS­HER trai­ning uses nego­tia­ti­on simu­la­ti­ons, which may well spur com­pe­ti­ti­on at times, we place gre­at empha­sis on a sup­port­i­ve and col­la­bo­ra­ti­ve lear­ning envi­ron­ment.
