Presents the procedures, results, and conclusions of a study to compare the effectiveness of the open-ended chemistry laboratory with the traditional laboratory. Different classes of high school students in a college-preparatory chemistry course were exposed to the two laboratory techniques. The achievement tests and the Watson-Glaser Critical…

This study was designed to identify those science concepts and mathematical skills that may be the source of student difficulty in learning chemistry as developed by the Chemical Education Materials Study (CHEMS). The instruments utilized were four Achievement Tests prepared by CHEMS. Each test item was analyzed to determine the concepts and/or…

REPORTED IS A STUDY WHICH (1) ANALYZED THE EFFECTIVENESS OF A TEACHING METHOD DEVELOPED TO IMPROVE THE STUDENT'S SCIENCE PROBLEM-SOLVING ABILITY, AND (2) INVESTIGATED THE RELATIONSHIP BETWEEN THE PROBLEM-SOLVING SKILLS MEASURED AND THE STUDENT'S SCIENCE BACKGROUND, CRITICAL THINKING ABILITY, AND GRADE POINT AVERAGE. CONCLUDED WAS (1) THAT THE…

Reports the presence of a facilitating effect of exposure to a pretest on the Watson-Glaser score and a posttest following grade 12 biology instruction. (AL)

The effects of certain teaching methods upon the development of critical thinking skills, an understanding of science and scientists, and knowledge of subject matter were investigated. An analysis of covariance and rank correlation between teacher behavior patterns and particular student outcomes on the "Watson-Glaser Critical Thinking…

Presents the procedures, results, and conclusions of a study designed to determine (1) student's understanding of science and (2) ability to think critically. Subjects were 791 graduating high school students in South Australian schools. No differences in the learning outcomes were found for students attending four types of schools. Bibliography.…

THIS INVESTIGATION WAS DESIGNED TO COMPARE CHANGE IN CRITICAL THINKING IN GROUPS OF STUDENTS STUDYING HIGH SCHOOL BIOLOGY IN LABORATORY-CENTERED CLASSES AND IN LECTURE-DEMONSTRATION-CENTERED CLASSES. TWENTY BIOLOGY CLASSES WERE RANDOMLY SELECTED FROM THE FOUR SENIOR HIGH SCHOOLS IN THE SALT LAKE CITY SCHOOL DISTRICT. TEN CLASSES WERE RANDOMLY…

This study examined the ethnic background, recency of immigration, and college aspirations of the Catholic high school seniors in the Test Every Senior Project and explored the relationships of these factors to achievement. Data concerning 5,705 Catholic high school seniors in the Cleveland diocese were gathered. Through the demographic data,…

This study was designed to evaluate the success of an experimental secondary school course for fostering scientific literacy and the development of scientific attitudes. Students were matched using I.Q., sex, grade level, involvement with formal science courses, and cumulative grade point average. Twenty-one "self selected" eleventh and…

Compared, for selected outcomes, were integrated chemistry-physics courses with chemistry and physics courses taught separately. Three classes studying integrated Physical Science Study Committee (PSSC)-Chemical Bond Approach (CBA), and three classes studying integrated Physical Science Study Committee-Chemical Education Materials Study (CHEMS)…

The effects of the type of earth science course (Earth Science Curriculum Project (ESCP) and non-ESCP), the directness or indirectness of teacher-pupil interaction in various teaching activities (I/D ratio), and the teacher's philosophical orientation (T/NT ratio) on various student outcomes such as understanding of science and scientists;…

Grade seven classes of high potential and average potential students were randomly assigned to control or experimental groups. After the experimental group had used a curriculum unit - "Ecology: The Web of Life" - which was designed to emphasize higher level cognitive abilities, the Watson Glaser Critical Thinking Appraisal was…

RELATIONSHIPS BETWEEN ENVIRONMENTAL AND TEACHER CHARACTERISTICS AND STUDENT LEARNING IN NINTH GRADE SCIENCE ARE INVESTIGATED. NINETY-THREE NINTH GRADE SCIENCE CLASSES WERE SELECTED FROM THOSE TAUGHT IN NORTH CAROLINA. STUDENTS WERE PRETESTED IN THE FALL AND POST-TESTED IN THE SPRING FOR SCIENCE ACHIEVEMENT, UNDERSTANDING OF THE SCIENTIFIC…

The outcomes of 1333 students enrolled in Chemical Educational Materials Study (CHEMS), Chemical Bond Approach (CBA), and a traditional chemistry course were compared on the basis of grade and ability level. For the total group, students taking CHEMS and CBA performed significantly better on the American Chemical Society Cooperative Examination in…
