Recent multiplication with regrouping research shows that the combination of the concrete-representational-abstract (CRA) sequence and the Strategic Instruction Model (SIM) has been effective in several studies. More evidence is needed to demonstrate CRA-SIM's effectiveness across settings and students. Therefore, the purpose of this study was to…

This paper examines how students make progress toward three-dimensional (3D) understanding of the patterns of evolution. Specifically, it proposes a learning progression that explains how scientific practices, crosscutting concepts, and disciplinary core ideas come together in naming and grouping, length of change over time, and the role of common…

Science teaching and learning require knowledge about how learning takes place (cognition) and how learners interact with their surroundings (affective and sociocultural factors). The study reported on focussed on learning for understanding of Newton's second law of motion from a cognitive perspective that takes social factors into account. A…

An experiment on sequence procedures for presenting text materials to pupils demonstrated that web sequencing (presenting concepts as related parts of a network) resulted in better test performance than linear sequencing. Information processing strategies used by pupils did not influence either the sequence of information presentation or test…

Computer-naive university students (N=124) were taught the BASIC programing language by solving and receiving feedback on program comprehension problems stated in BASIC or on corresponding problems stated in English followed by problems stated in BASIC. Results support a sequential method of instruction beginning with use of natural language…

Reviews study of 80 undergraduate sociology students which compared the effects of two types of sequencing in computer assisted instruction: (1) linear, or fixed, and (2) flip, or branching. Results indicate that students in the flip sequence condition performed better on comprehension measures but not on retention measures. (Author/LRW)

Discussion of control over sequence of instruction in computer-assisted instruction (CAI) focuses on a follow-up study that examined the effects of the breadth and depth of menus and the meaningfulness of menu category names on the learning and attitudes of college students. Posttests are described, and results are analyzed. (16 references) (LRW)
