 In developing a curriculum (whether in a specific subject area, or more broadly as the whole range of offerings in an educational institution or system), a number of difficult decisions need to be made. Issues such as the proper ordering or sequencing of topics in the chosen subject, the time to be allocated to each topic, the lab work or excursions or projects that are appropriate for particular topics, can all be regarded as technical issues best resolved either by educationists who have a depth of experience with the target age group or by experts in the psychology of learning and the like. But there are deeper issues, ones concerning the validity of the justifications that have been given for including/excluding particular subjects or topics in the offerings of formal educational institutions. (Why should evolution or creation “science” be included, or excluded, as a topic within the standard high school subject Biology? Is the justification that is given for teaching Economics in some schools coherent and convincing? Do the justifications for including/excluding materials on birth control, patriotism, the Holocaust or wartime atrocities in the curriculum in some school districts stand up to critical scrutiny?)
