Pretest and posttest for attitude toward science domain of science teaching were administered to students in both experimental and control groups. The pretests were spread over a two week interval prior to the beginning of the experiment. The posttests were conducted one semester later following the instruction. The attitude and perception data were collected as a way of closing the semester. In general, an emphasis upon assessment and student change as evidenced by pretesting and posttesting was maintained as a normal part of science instruction. Figure 2 is a list of differences between STS instruction and textbook-oriented instruction:
Figure 2: Comparison of Instructional Strategies Characterizing STS and Textbook-Oriented Classes
Textbook-Oriented
STS
Textbook visible and used frequently Textbook used only when it is needed as source of information
Teachers provide information for students to record and to repeat on tests
Teachers assist students in finding answer to their own questions; teachers rarely provide information
Activities are all prescribed, including goals, procedures, and often results
Students plan activities as a way of testing their own ideas and explanations
No focus on current problems and issues
Current problems and issues often provide the context of the study
Science defined by what information is included in the text
Science defined as questions, possible answers to questions, and testing the possible answers which emerge
Teachers plan each lesson carefully
Teachers focus on goals and involve students in planning activities, actions, and source of information
Students doing what text and teacher direct them to do
Students proposing actions, information sources, and new questions
Focus upon words and terms from textbook
Terms rarely used as a focus by themselves; special terms are used only after meaning has been established
Ideas and information are presented for mastery
Ideas and information sought out to respond to issues and questions
No use of newspaper and periodicals
Frequent use of news current reports and current situations
Much work on text and teacher-prepared worksheets
No work on text and teacher-prepared worksheets
Science not viewed as operating in the school and/or community; i.e., no local relevance
Nearly all questions, issues, and class activities have a base and a relevance at the local level
Much time spent by teacher in preparing lessons
Students involved as much as (if not more than) teacher in preparing for individual lesson
Class discussion and laboratories focus on competition and getting right answer
Discussion and laboratories focus on responding to issues, questions, and problems
Quizzes and tests focus on student recall
Evaluation focuses on what students can do; i.e. , how they can use information and skills
