Starting in 1944, while still a student, Malkin published literary, cinema, and theater critiques, and served as the editor of
On the Wall, the magazine of the
Hashomer Hatzair youth movement (1944–1946). During the
1948 Arab-Israeli War, he served as a broadcasting officer for the
Haganah and the
IDF (1947–1948) in the
underground radio station,
Telem Shamir Boaz, that later became the
Israel Army Radio (
Galei Tzahal). Malkin lectured (in
Yiddish) and was active in the
Cyprus internment camps before the inmates were sent to Israel, and worked for the IDF arms procurement branch in France 1949. He directed and lectured in Pomansky College for Judaism as Culture in New York in 1951, and founded and directed a Hebrew
Ulpan (language school) in the
Quartier Latin in
Paris in 1956. While in Paris, he also worked as assistant to the
cultural attaché at the Israeli embassy in Paris. He also participated in a lecture tour on Judaism in world literature in Australia (1960), the United States (1965), and France (1970). From 1952 to 1956, Malkin taught
comparative literature studies and the Bible as literature at the
Seminar HaKibbutzim teachers' college in
Tel Aviv. At the same time he served as director of the repertoire department at the
Habima national theater and as a drama instructor at the theater schools of Habima and of the
Cameri Theater. From 1971 to 1981, he founded and directed the
Mateh Yehuda community college, which employed the educational methods of
Empire State College (SUNY) where students create personal tracks of study. This was adopted to conditions in Israel and to the particular requirements of working students in the Mateh Yehuda area. From 1969 to 1994, Malkin taught aesthetics, theater and film criticism at the
Tel Aviv University. In 1971 he established, together with the Dean of the Faculty for New Arts, Professor
Moshe Lazar, the Department for Cinema and Television at the Tel Aviv University. He also served as the university's representative in the founding team of the
Tel Aviv Cinematheque, and as editor of the "Cinematheque Pages" – film criticism essays handed out to viewers before the screening of each movie, together with
Uri Klein. From 1958 to 1971, Malkin founded and directed the first community centers in
Haifa, Beit Rothschild and the Beit Hagefen Jewish–Arab Center. These municipal centers were at first run by groups of friends who led the centers' dozens of social activities, including the
Haifa Cinematheque, built inside Beit Rothschild. During these years Malkin also lectured in the
Technion (Israel Institute of Technology) on aesthetics and rhetoric. Malkin later served as editor-in-chief for
Free Judaism, a magazine for Judaism as a culture, which he founded in 1995 and which came out in print editions until 2004. Malkin also served as
provost at the
International Institute for Secular Humanistic Judaism, based in
Jerusalem and
Farmington Hills, Michigan (
Birmingham Temple). The Institute trains students who hold an undergraduate degree to be community leaders for secular communities and those with a master's degree or a PhD to be secular rabbis in a four-year track of studies and work. ==Writings==
