A structural/cross-sectional micro-analytic perspective prevails in the Socio-constructivist research of peer knowledge construction. This paper proposes an alternative micro-sequential approach that focuses on the transitions between events during the activity. From this micro-sequential perspective, the study aimed to (a) explore the…

This study tested how different implementations of explaining and drawing activities affect learning from a multimedia science lesson. After studying a multimedia slideshow about the human respiratory system, college students (n = 145) were assigned randomly to one of four learning activity conditions: write explanations before drawing pictures…

This study aimed to make a teaching model out of the instructional flows of the teachers teaching engineering chemistry course. Specifically, the study aimed to identify the teaching styles the teachers used in the actually delivery of the chemistry lessons. Thus, this is a descriptive study on the teaching style employed and learning styles…

This paper reports on our use of a fine-grained learning progression to assess secondary students' reasoning through carbon-transforming processes (photosynthesis, respiration, biosynthesis). Based on previous studies, we developed a learning progression with four progress variables: explaining mass changes, explaining energy transformations,…

Purpose: This study presents the development and evaluation of a Constructively Aligned Teaching Sequence (CATS) for teaching the organismal biology of Senior High School. It tried to explore teaching-learning activities and assessment tasks that may be designed to address students' conceptions and teachers' difficulties in teaching organ systems.…

This paper discusses Multi-Feature Hierarchical Sequential Pattern Mining, MFH-SPAM, a novel algorithm that efficiently extracts patterns from students' learning activity sequences. This algorithm extends an existing sequential pattern mining algorithm by dynamically selecting the level of specificity for hierarchically-defined features…

The Program for Learning in Accordance with Needs (PLAN) was devised to be self-improving through a system of computer analysis of student performance data. The PLAN instructional program consists of teaching-learning units in various subject areas, such as reading and science, which are composed of self-paced alternative learning activities,…

Designed to assist bilingual teachers in providing a coordinated program of studies for students in the Connecticut Migratory Children's Program and others whose native language is Spanish, this bilingual-bicultural science curriculum guide for second grade is one of a series for pre-school through fifth grade. The overall focus is on Puerto Rican…
