T h e first and major section of this paper reports some of the many published papers t h a t have direct implications for science teaching.

A tnhle lists I6 examples of things in general chemistry which "Pref,~rmal"at~~dpnts can do and lfi corresponding things that they cannot do. Since a suhstnntial number of entering college students do not function at the formal reasoning level, Herron suggests how rh~mistryeont~nt.can be made more accessible to these students. 121 Vmiz R.."Thp Philmophv d . h n Pingel and its Ua4fulnep. toTeachemof Chemistry." .IFF.'. 49.807 119721.

Paper 9 and the three that follow refer to physia teaching but many of the ideas are applicable to chemistry teaching as well. Self-regulation, the process of refining and advancing one's reasoning ahility, isviewed in termsofwhat a physics teacher can do to encourage students to engage in the process. Eleven problems are provided as examples of ways the teacher can promote self-regulation in students. i l l ) MeKinnon, J., and Renner.

Ron Good received the PhD degree fnrm the UniverGty 01 Nwlh C a n h a at Chnpel HIII and heran hiz wwk in science education at Ylor~dnSlate ilni\er;ity in 1968 He has wrirlrn numerous articles on the nature of science learning and his most recent h k . "How Children Learn Science" applies many of Piaget's research findings in developmental psychology to the field ofscience education. HIScurrent research activity is directed toward learning more about the development of formal thought and how the content of science can be used to facilitate such thinking. E. K.Mellan recaved the PhD at the University ofTexas (Austin) in 1963. After a year as instructor of St. Edward's University (Austin), he was a pnstdoctoral fellow and lecturer a t the University of Michigan (Ann Arbor). He has been eoordinator of general chemistry at Florida State since 1966. His research interests involve synthetic inorganic chemistry and chemical education. Robert A. Kromhout has taught physics for more than 26 years, and for 22 years at Florida State. He obtained his BS at Kansas State University (then College) in 1948, and his PhD at the University of Illinois in 1952. His research interestsare phase transitions theury, effects of van der Waals interactions. and pedagogy.

As a follow-upto paper 1, Herron describes specific ways in which the chemistry teacher urn differentiate between students who can use formal reasoning and those who cannot. He suggests that even with students capable of formal thought and abstractions, i t is important to relate such concepts as thermodynamics, chemical bonding, etc. t o concrete examples as often as possible. The ehemistry curriculum should be designed so that many concrete experiences and examples are used as the foundation for concepts and activities that require formal reasoning. (15) Lippinmtt. W.. "Piaget: How Best to Use HisFindmgi." JCE. 55.139 (19781. In this editorial, the ehemistry teacher is cautioned against using Piaget as an excuse to remove the complexity of chemistry content. There should be an increased awareness that some students have deficiencies in reasoning ability and the challenge t o the chemistry teacher is t o use the content of chemistry in ways that will facilitate the development of the kind of thinking needed to understand ehemistry. 116) Karplus.

About half of the 131 college freshmen in this study were eategorized as lacking formal reasoning ability. The authors report evidence that inquiry-oriented science courses lead to better performance on Piagetian-type tasks of formal thought. (241 Koldiy, G.."Cognitive Development and Science Tesehing:'JRST. 14.21 (1977). A far higher percentage of science oriented students were found to be capable of formal reasoning than is usually the case for randomly sampled groups. 125) Lawon.A. and Renner, J.,"A Quantitative Analmi, of RasponsostoPisgotianTasLs and Its Imolicationr for Curriculum?

Results of tests on probability and eomhinatorial reasoning indicated that fewer than half of the 90 students in the sample could correctly predict outcomes. The effects of genetics instruction on these reasoning abilities were very small.

Similar t o paper (35), evidence is offered that suggests instruction (training?) can effect an advance in reasoning ability of young students (11-12 years). However, there seems to be little "transfer" of this traininp to tasks involving different forms of formal reasoning. (371 ~oulanger,~ . .
