Purpose: This study reports on the outcome of an investigative inquiry approach - Model Based Inquiry (MBI) on achievement and critical thinking of college pre-service chemistry teachers. Methodology: Anchored on Constructivism, the study employed quasi experimental (nonequivalent control group) design. A total of 174 level 200 college pre-service…

Laboratory experimentation in the context of school science is a widely advocated teaching strategy for the simplification of several abstract scientific concepts. Laboratory-based learning activities have proven to enhance learners' conceptual and procedural understandings of micro chemical phenomena, thus boosting achievement in chemistry…

The methodological limitations education researchers face in the evaluation of reformed instruction have led to debates as to the evidence advancing evidence-based practices. To conduct more effective research, methodological pluralism in the evaluation of educational reforms can be used to complement the strengths and limitations of a corpus of…

Javits Gifted and Talented Education Program has provided a wealth of knowledge on culturally and linguistically diverse (CLD) gifted learners and how to support teachers in their work with CLD students. This study examined five impactful Javits projects through qualitative inquiry centered on how innovative practice takes root or not. Using…

The SUN approach to biological energy transfer education is fundamentally different from past practices that trace chemical and energy inputs and outputs. The SUN approach uses a hydrogen fuel cell to convince learners that electrons can move from one substance to another based on differential attraction. With a hydrogen fuel cell, learners can…

This research is part of a study on scaling-up middle school science curriculum units in a large, diverse public school system. Chemistry That Applies (CTA), a guided inquiry unit based on conceptual change theory and highly rated according to the Project 2061 Curriculum Analysis, was implemented in five middle schools matched demographically with…

As part of its mission, the International Association for the Evaluation of Educational Achievement (IEA) is committed to the development of the community of researchers who work in the area of assessment both nationally and internationally. The association also has a commitment to provide policymakers with the types of data and analyses that will…

The purpose of this study is to compare the efficacy of three different approaches to professional development in Earth science education: preparing teachers to "adopt" expert-"design" curricula; preparing teachers to use a principled approach to design curricula; and preparing teachers to use a principled approach to "adapt" curricula. The claims…
