Digestion of DNA with restriction enzymes, calculation of volumes and concentrations of reagents for reactions, and the separation of DNA fragments by agarose gel electrophoresis are common molecular biology techniques that are best taught through repetition. The following open-ended, investigative laboratory exercise in plasmid restriction…

Here, we describe a laboratory experiment as part of an upper-level vertebrate physiology course for biology majors to investigate the physiological response of vertebrates to osmoregulatory challenges. The experiment involves measuring plasma osmolality and Na[superscript +] -K[superscript +] -ATPase activity in gill tissue of teleost fish…

This appendix contains descriptions of several laboratory-type experiences suitable for a training program for educational leaders. Activities include a series of 10-minute microlab experiences, lecturettes followed by skill sessions, T-Group games, and various other experiences to stimulate self-exploration, group intercommunication, observation,…

Changing culture requires interventions invalidating old processes and conditions that facilitate the creation of new self validating processes. The personal growth laboratory becomes a temporary system of new self validating processes. Prepared for a conference on Intensive Small Group Process sponsored by Foundations Fund for Research in…

Small, interpersonal process groups may be useful in preparing teachers for work in inner-city schools. The intensive group experience can result in improved communication and interpersonal relationships (not only, for instance, between student teachers and cooperating teachers, but also in their interaction with professional colleagues, pupils,…

Warns of the possible dangers of encounter groups. (JF)

Students' views about science were correlated with their approaches to lab practice. Three distinct cases are discussed in detail: empiricist-oriented, rationalist-oriented, and constructivist-oriented students. A coherent epistemological theory was constructed for each case, by considering the different degrees of certainty and confidence each…

It is proposed that this culture alleviates basic personal and group anxieties by offering defensive satisfactions. Strong social norms and the technical designing" of the staff tend to maintain an artificially united community," benevolently ruled. Also suggested is that Bethel culture serves to preserve American society from internal and…

This appendix contains descriptions of three exercises designed to develop basic communications skills for improving interpersonal relations. Each exercise--designed to be engaged in by teachers in dyads, triads, quadruples, or similar groups without the presence of a skilled leader--includes a statement of the problem, description of the skill…

A new technique for teacher education has been developed in response to the belief that teacher education's number one priority is to be concerned with the emerging self of the teacher trainee. Research on effective teaching has revealed that it is not what the teacher is taught that is the critical factor but the way in which the knowledge and…
