Investigating the Effect of van Hiele Phase-Based Instruction on Pre-Service Teachers' Geometric Thinking
Peer reviewed Peer reviewed
PDF on ERIC Download full text
Armah, Robert Benjamin; Cofie, Primrose Otokonor; Okpoti, Christopher Adjei – International Journal of Research in Education and Science, 2018
This study investigated the effect of van Hiele Phase-based Instruction (VHPI) on Ghanaian Pre-service Teachers' (PTs') geometric thinking in terms of the van Hiele Levels. A pre-test post-test quasi-experimental design was employed. There were 75 PTs each in the experimental group and the control group. Van Hiele Geometry Test (VHGT) was…

Developing Conceptual Understanding and Procedural Fluency for Junior High School Students through Model-Facilitated Learning (MFL)
Peer reviewed Peer reviewed
PDF on ERIC Download full text
Laswadi; Kusumah, Yaya S.; Darwis, Sutawanir; Afgani, Jarnawi D. – European Journal of Science and Mathematics Education, 2016
Conceptual understanding (CU) and procedural fluency (PF) are two important mathematical competencies required by students. CU helps students organizing their knowledge into a coherent whole, and PF helps them to find the right solution of a problem. In order to enhance CU and PF, students need learning experiences in constructing knowledge and…

Influence of Using Challenging Tasks in Biology Classrooms on Students' Cognitive Knowledge Structure: An Empirical Video Study
Peer reviewed Peer reviewed
Direct linkDirect link
Nawani, Jigna; Rixius, Julia; Neuhaus, Birgit J. – International Journal of Science Education, 2016
Empirical analysis of secondary biology classrooms revealed that, on average, 68% of teaching time in Germany revolved around processing tasks. Quality of instruction can thus be assessed by analyzing the quality of tasks used in classroom discourse. This quasi-experimental study analyzed how teachers used tasks in 38 videotaped biology lessons…

Gavin, M. Katherine; Casa, Tutita M.; Adelson, Jill L.; Firmender, Janine M. – Journal for Research in Mathematics Education, 2013
The primary goal of Project M[superscript 2] was to develop and field-test challenging geometry and measurement units for all K-2 students. This article reports on the achievement results for students in Grade 2 at 12 urban and suburban sites in 4 states using the Iowa Tests of Basic Skills (ITBS) mathematics concepts subtest and an open-response…

Individual to Collaborative: Guided Group Work and the Role of Teachers in Junior Secondary Science Classrooms
Peer reviewed Peer reviewed
Direct linkDirect link
Fung, Dennis; Lui, Wai-mei – International Journal of Science Education, 2016
This paper, through discussion of a teaching intervention at two secondary schools in Hong Kong, demonstrates the learning advancement brought about by group work and dissects the facilitating role of teachers in collaborative discussions. One-hundred and fifty-two Secondary Two (Grade 8) students were divided into three pedagogical groups, namely…

Investigating the Effect of Origami Instruction on Preservice Teachers' Spatial Ability and Geometric Knowledge for Teaching
Peer reviewed Peer reviewed
PDF on ERIC Download full text
Akayuure, Peter; Asiedu-Addo, S. K.; Alebna, Victor – International Journal of Education in Mathematics, Science and Technology, 2016
Whereas origami is said to have pedagogical benefits in geometry education, research is inclusive about its effect on spatial ability and geometric knowledge among preservice teachers. The study investigated the effect of origami instruction on these aspects using pretest posttest quasi-experiment design. The experimental group consisted of 52…
