The application of psychology and technology are used in the learning process while we use programmed learning modules. In programmed learning we use the small steps of learning resulting in mastery. The modules helps to respond the learners activity and to give immediate feedback. The learners will get their own timing to go through the lessons…

Parallel machine and manual literature searches on the subject of chemical evolution and the origin of life were compared on six characteristics: (1) precision, (2) recall, (3) novelty, (4) uniqueness, (5) time cost per citation, and (6) dollar cost per citation. The manual search outperformed the machine on precision, novelty, uniqueness, and…

The purpose of the study was to determine the relationship between a personality trait, dependence-proneness, and performance in the high school chemistry laboratory; to arrange laboratory groupings based on the pupil trait of dependence-proneness and to determine if these groupings affect laboratory performance; and to include and test other…

The purpose of the study was to determine differences in chemistry resulting from a traditional and an independent technique of teaching. The population included four chemistry classes at Scottsdale Saguaro High School. Intact groups were assigned to experimental or control groups by random processes. The control group was presented the CHEM Study…

The purpose of this study was to determine the effectiveness of doubling the laboratory experiments and time in the laboratory on student achievement, performance on laboratory skills, and attitude toward high school chemistry. One hundred forty-three students were assigned either of two treatments. All students performed the same basic…

This investigation explored the question of how high school chemistry students best learn three-dimensional molecular, ionic, and metallic structures in CHEM Study (Freeman, 1963). The experimenter compared the achievement, attitude, and instructional preferences of 110 randomly selected students taught by two different methods: (1) student…

This was a quantified study on the learning of certain theoretical topics in general chemistry as influenced by two methods of visual technique (single concept films, overhead projections). Four classes of chemistry students (non-science majors) registered in sections on a random basis, participated. Objective, multiple choice tests on each of the…

The ultimate goal of this study was to specify conditions which affect achievement in the chemistry laboratory through an understanding of instructor-student interaction. The Flanders System of Interaction Analysis was used to measure the ratio of indirect to direct teaching (I/D/ Ratio) during pre-lab and post-lab sections of eight two-hour…

An experimental treatment consisting of inquiry laboratory experiences was administered to a group of 41 students enrolled in an introductory college chemistry course. Using a control group of 36 for comparison, students were evaluated to determine attitudinal changes, critical thinking skills, content mastery, laboratory performance skills, and…

Investigated were possible relationships between performance in general college chemistry and secondary school preparation in chemistry. The researcher examined achievement in general college chemistry as a possible function of the student's high school science courses, mathematics courses, socioeconomic status, and scores on the ACT tests. Data…

The problem of this study was to compare teaching methodology and teaching strategies used in general chemistry courses to the attitudes and values of the students taking those courses. Objectives of the study included: (1) an investigation of the teaching methodology in use in chemistry courses, (2) a study of the attitudes of students toward…

This research was undertaken to determine whether the mathematics course offered to students taking courses in chemical technology was adequate. Students in a regular class and an experimental class were given mathematics and chemistry pretests and posttests. The experimental class was taught using a syllabus designed to maximize the coherence…

The author sought to establish reasons for secondary school students' selecting chemistry as part of their course of studies. Another aspect of the study related to predictor variables and the study of chemistry, and a third aspect related to the type of curriculum used--Chemical Education Materials Study (CHEMS) or traditional. Eleventh-grade…

This study was concerned with the effect of subsuming concepts on student achievement and the interaction effect of subsumers with high and low organizing ability. One hundred forty-three subjects (Ss), enrolled in six sections of a class in undergraduate chemistry, were administered an organizing ability test and rank ordered according to the…

This research investigated the need to apply appropriate results of research in pedagogical techniques of questioning to accomplish maximum achievement through the use of high-level questions and to encourage thought and participation in the learning process. A unit on radioactivity and radiation was prepared, validated and taught by 14 carefully…
