Mastery,insight, and the teaching of chemistry

The learning of chemistry is described as a process analogous to the process of making chemical discoveries. Historical examples are given to show how chemists have used their insight to break out of a conceptual loop in order to advance the science. Having the insight to make the intuitive leap necessary to break a conceptual loop is as important as having the mastery of the pertinent facts. As in making chemical discoveries, learning elementary chemistry requires developing insight as well as acquiring mastery of the facts. However, current general chemistry teaching tends to teach facts first and insight later. Suggestions for improving this situation so that insight and facts are learned together are given. Finally, the nature of insight is probed more deeply and presented as a two-step process where the first step is an evaluation of the perceptions about science which are held. Once the student, teacher, or researcher has a clear evaluation of the validity of the perceptions that he or she holds, further significant progress toward understanding or scientific discovery is possible.     

The science support scale: Its appropriateness with high school students

Implementing the idea that more emphasis should be placed on student achievement in the affective domain is contingent upon the concurrent development of suitable instruments for the assessment of prescribed criteria. One such instrument, the Schwirian Science Support Scale (Tri-S scale), was reported in a recent NSTA publication as a promising tool for measuring student science support. Recent research using the Tri-S scale with high school pupils showed that scores on this instrument did not increase after the students had taken a tenth grade introductory course in biology. Further analysis indicated students of teachers scoring “high” in science support did not produce higher scores on the Tri-S scale than students studying biology from teachers “low” in science support. Reliability estimates using high school student scores were well below previous estimates using scores from college undergraduates. Factor analysis of inter-item correlations indicated that student interpretation of item meaning did not correspond to the five subtest structure of the Tri-S scale. Findings from this study demonstrate that the Tri-S scale is not an appropriate instrument for measuring attitudinal changes of tenth grade high school students. This study is suggestive of the fact that went and future instruments that purport to measure achievement in noncognitive areas should be carefully analyzed before they are recommended for use with specific populations.     

Abstraction and Consolidation

The framework for this paper is a recently developed theory of abstraction in context. The paper reports on data collected from one student working on tasks concerned with absolute value functions. It examines the relationship between mathematical constructions and abstractions. It argues that an abstraction is a consolidated construction that can be used to create new constructions. Newly formed constructions are fragile entities. In the course of consolidating a construction this student creates connections between the new construction and already established mathematical knowledge and develops a language to describe and guide mathematical actions related to the construction. The resulting abstraction is a more resilient form of the construction and the student is able to justify his assertions. The paper also examines issues in designing tasks to consolidate a construction.     

Can students within higher education learn to be resilient and,educationally speaking,does it matter?

This paper presents a critical appraisal of resilience and its associated concepts within the context of higher education. It addresses wide‐ranging definitions of resilience, encompassing endurance and adaptability, and seeks to understand how these definitions impact on the learning experiences of students. As theoretical and empirical work on resilience has burgeoned in terms of adolescent experiences of education, the rise of interest has not been matched by that in studies of adult learning, particularly within university settings. This is despite the growing importance of retention studies, which have clear and important links to how well students manage their learning ability in adversity. Realization of the potential embodied in this concept to alter for the better, together with ways of conceptualizing learning and teaching, however, will remain constrained unless teachers within higher education pay attention to the resilience narratives that individual students present, and how teaching strategies can affect their learning trajectories. The paper examines some factors that impact on students’ learning within higher education, and theorizes how teaching and assessment may be adapted to promote resilience in all its forms.     

Perceptions of,and reactions to,the educational system and their implications for policy

The data to be presented was drawn from a survey of nationally representative samples of some 4,000 pupils, most of whom were no longer required by law to be at school, and 1,200 teachers, in the Republic of Ireland. The main purpose of the survey was to collect data relevant to evaluating the post-primary educational system as a whole. Providing such an evaluation was taken to involve, first, assessing what the goals of post-primary education should be, second, obtaining teachers' and pupils' subjective assessments of whether those goals were being attained and, thirdly, asking why the goals were not being better attained. The basic data, which has bee published in three volumes by the Irish Association for Curriculum Development (Raven et al., 1975/ 1976), can be used to illuminate a wide range of basic issues. The present paper deals with one of these. Some others are discussed in Raven (1977b).
