A Dance Tour Abroad The unstoppable Mary Craighill, 69, and six members of her St. Mark's Dance Company on Capitol Hill performed during a two-week tour of Denmark and the Soviet Union this summer.

Selected in part for its longtime educational involvement in the community, the liturgical dance troupe from St. Mark's Episcopal Church presented a program of modern, jazz and tap dance in Copenhagen, Leningrad, Moscow and the city of Krasnodar in the southwest Soviet Union.

Craighill has been dancing since she was 13. She founded the St. Mark's company 25 years ago and has concentrated on developing original choreography, liturgical activities and performances in area schools, hospitals and clinics.

The touring dancers included Alexandra Arriaga, Karen Carra, Kathy Crosby, Ines Dunn, Tyrone Woods and Jessica Sloane.

Their most memorable moment came in Krasnodar, where they danced on the same stage as had Isadora Duncan: "The theater was filled, and at the end we were showered with flowers and gifts, and a citation from the mayor," Craighill said.

Science for Teachers Six city schoolteachers were among 40 from the mid-Atlantic region who attended a science educators' institute this summer sponsored by Bell Atlantic and the American Association for the Advancement of Science.

Clayton Harrison Jr., of Kramer Junior High; Amy Lee, of Rabaut Junior High; Gregory Poole, of the D.C. Street Academy; Robert Scott III, of Fletcher-Johnson Junior High; Annette White, of Nalle Elementary; and Robert Wood, of the D.C. Public Schools Planetarium, participated in a two-week, graduate-level seminar on advancements in computer and telecommunications technologies taught by George Washington University professors.

10 Students Do Research Ten students from the 10th and 11th grades of D.C. high schools spent eight weeks this summer assisting in area medical institutions and participating in scientific research projects as scholars in the 27th annual American Cancer Society's Katherine Dulin Folger Summer Scholarship Program.

The students were Katherine Abbruzzese and Anne Baker, of Georgetown Visitation; Tshaka Cunningham and Stephen Stanford, of St. Albans; Joel Dolojan, of Gonzaga High; Edwin D'Souza, of Blessed Sacrament; Tamikka Evans, of Eastern; Nina Fry, of the Field School; and Nina Obichere and Charmian Pitts, of Banneker High. The students were paired with scientists doing research in specialized medical fields.

D'Souza had special interest in the program, having been diagnosed earlier with a rare form of eye cancer. His successful treatment spurred him to organize a walkathon that raised $17,000 for research, and has now made him decide to pursue a career in medicine.
