has been a backlash against Marxist thought in post-communist states (see sociology in Poland). However, it remains dominant in the sociological research sanctioned and supported by communist states (see sociology in China). Economics Marxian economics is a school of economic thought tracing its foundations to the critique of classical political economy first expounded upon by Karl Marx and Friedrich Engels. Marxian economics concerns itself with the analysis of crisis in capitalism, the role and distribution of the surplus product and surplus value in various types of economic systems, the nature and origin of economic value, the impact of class and class struggle on economic and political processes, and the process of economic evolution. Although the Marxian school is considered heterodox, ideas that have come out of Marxian economics have contributed to mainstream understanding of the global economy. Certain concepts of Marxian economics, especially those related to capital accumulation and the business cycle, such as creative destruction, have been fitted for use in capitalist systems. Education Marxist education develops Marx's works and those of the movements he influenced in various ways. In addition to the educational psychology of Lev Vygotsky and the pedagogy of Paulo Freire, Samuel Bowles and Herbert Gintis' Schooling in Capitalist America is a study of educational reform in the U.S. and its relationship to the reproduction of capitalism and the possibilities of utilizing its contradictions in the revolutionary movement. The work of Peter McLaren, especially since the turn of the 21st century, has further developed Marxist educational theory by developing revolutionary critical pedagogy, as has the work of Glenn Rikowski, Dave Hill, and Paula Allman. Other Marxists have analyzed the forms and pedagogical processes of capitalist and communist education, such as Tyson E. Lewis, Noah De Lissovoy, Gregory Bourassa, and Derek R. Ford. Curry Malott has developed a Marxist history of education in the U.S., and Marvin Gettleman examined the history of communist education. Sandy Grande has synthesized Marxist educational theory with Indigenous pedagogy, while others like John Holt analyze adult education from a Marxist perspective. Other developments include: the educational aesthetics of Marxist education Marxist analyses of the role of fixed capital in capitalist education the educational psychology of capital the educational theory of Lenin the pedagogical function of the Communist Party The latest field of research examines and develops Marxist pedagogy in the postdigital era.
