A distance measure for automatic document classification by sequential analysis

This research has investigated the feasibility of using a distance measure, called the Bayesian distance, for automatic sequential document classification. It has been shown that by observing the variation of this distance measure as keywords are extracted sequentially from a document, the occurrence of noisy keywords may be detected. This property of the distance measure has been utilized to design a sequential classification algorithm which works in two phases. In the first phase keywords extracted from a document are partitioned into two groups—the good keyword group and the noisy keyword group. In the second phase these two groups of keywords are analyzed separately to assign primary and secondary classes to a document. The algorithm has been applied to several data bases of documents and very encouraging results have been obtained.     

Graduate degrees by external studies: the Nova University programmes in Florida

This article examines the graduate degrees by external study programmes offered by Nova University, Florida. These programmes have generated much criticism from traditional institutions in the United States of America, but the success of the programmes rests on the quality of academic staff recruited, programme evaluation techniques and student demand for the awards.     

Coping with textbook controversies: From policy development to implementation

This article focuses on how schools can cope with today’s increasing number of textbook controversies. Educators should understand the concerns generated by textbook controversies, the importance of sound and useful policies in dealing with them, how effective policies are developed, and the responsibilities of superintendents, principals, teachers, librarians, and publishers in addressing controversies and implementing policies.     

Promoting self-control of learning

The process of learning with understanding was investigated by case study of three male students learning genetics at a tertiary college. Five conclusions regarding the process arise from the study. These conclusions are: (1) Learning outcome is determined by decisions made by the learner. These decisions are influenced by learner perceptions and interpretations. (2) Inadequate learning is due to ineffective decision-making. This ineffective decision-making is associated with specific, recurring learning deficiencies. The main types of deficiency, deficient processing tendencies and misconceptions, cause inadequate performance and preclude learning with understanding. A total of seven tendencies was observed. Each learner applied tendencies idiosyncratically. Tendencies also generated particular misconceptions which further inhibited learning. (3) It takes energy to learn with understanding, or to unlearn a misconception. (4) Learners often are unaware of their deficiencies. This lack of awareness generates inappropriate attitudes. (5) Increased learner awareness of the nature and process of learning changes attitudes and procedures. The major implication of this study relates to promoting self-control of learning. It is proposed that improved learning will result from increasing learner awareness of the nature and process of learning, and by training learners in procedures for enhancing self-evaluation and decision-making.

Boyer in the Middle: Second Generation Challenges to Emerging Scholarship

This article reports on an examination of the distinctive second-generation challenges and opportunities faced by an early institutional adopter of the Boyer model of scholarship. Following the first cohort of faculty to be reviewed for tenure and promotion based on these criteria, we report the results of a survey designed to determine the perceptions of faculty and administrators of the degree to which emerging forms of scholarship had been integrated into the university culture including factors such as institutional identity, support structures, and faculty participation. This case study sheds light on the process of adaptation at this single institution and provides glimpses of how cultural change might occur across higher education.
