This paper presents a revised learning progression for the energy concept and initial findings on diverse progressions among subgroups of sample students. The revised learning progression describes how students progress towards an understanding of the energy concept along two progress variables identified from previous studies--key ideas about…

The authors examined whether students' epistemic and learning beliefs varied across different knowledge types in physics. On the basis of various beliefs frameworks, the authors predicted that individuals' beliefs would vary within a domain across the same content when presented conceptually versus procedurally. Participants were 81 high…

Background: In the last few decades, researchers have turned their attention to students' understanding of scientific concepts at different school levels. The results indicate that the learners have different ideas, and most of them are inaccurate in terms of those generally accepted by the scientific community. Purpose: This study was undertaken…

The purpose of this study was to investigate the effect of 5E learning cycle model oriented instruction (LCMI) on 11th-grade students' conceptual understanding of acids and bases concepts and student motivation to learn chemistry. The study, which lasted for 7 weeks, involved two groups: An experimental group (LCMI) and a control group (the…

In recent years, many countries have adopted a context-based approach for designing science curricula for education at all levels. The aim of this study was to determine the effectiveness of a Context-Based Chemistry Course (CBCC) as compared with traditional/existing instruction, on 11th grade students' learning about chemical equilibrium,…

The 11th Grade Test (1984) of the Illinois Inventory of Educational Progress includes 19 reading items, 45 geometry items, 46 science items, a 27-item student questionnaire regarding science opinions, and 49 mathematics items. The test booklet only is included here. (PN)

This study investigates whether or not (a) 252 Jamaican high school students (168 boys, 84 girls, 171 grade 10 and 81 grade 11 students) had favourable attitudes to biology, (b) their level of biology performance was satisfactory, (c) there were significant differences in their performance based on their gender, grade level, school-type,…

The Connecticut Assessment of Educational Progress (CAEP) is a continuing program designed to measure the efficiency of educational programs offered by public schools. During 1979-80, grades 4, 8, 11 were tested in science. The assessment goals were: to provide information on the quality of education in Connecticut; to collect and compare data…

This study aimed at establishing if the level of performance of 500 Jamaican Grade 11 students on an achievement test on the concept of respiration was satisfactory (mean = 28 or 70% and above) or not (less than 70%); if there were statistically significant differences in their performance on the concept linked to their gender, cognitive abilities…

The Pre-Postsecondary Program (PPSP) was conducted during the 1974-75 school year at four Ohio secondary schools in order to offer a career exploration program for students in grades 11 and 12 that would be related to the high school content and provide a foundation for careers in the students' areas of interest. The report presents the evaluation…
