Some of the main journals have published new (online first) articles that might be interesting to some:

• Heinz Steinbring wrote an article in ZDM, called: “Changed views on mathematical knowledge in the course of didactical theory development—independent corpus of scientific knowledge or result of social constructions?” In this article he shows how the didactical tradition in Germany has evolved in order to respond to new ideas and approaches in mathematics education.
• Jeff C. Marshall et al. wrote an article in International Journal of Science and Mathematics Education, called “K-12 Science and Mathematics Teachers’ Beliefs About and Use of Inquiry in the Classroom“. Here they describe how they made and used a survey instrument in order to measure mathematics and science teachers’ beliefs about and use of
  inquiry in the classroom.
• Vanessa Ramos-Christian et al. wrote an article in Early Childhood Education Journal, called “Math Fluency: Accuracy Versus Speed in Preoperational and Concrete Operational First and Second Grade Children“. They present a study that aims to investigate the relationship between cognitive ability and math fluency with 38 first and second grade
  elementary aged children.
• Ana Isabel Sacristán and Richard Noss wrote an article in International Journal of Computers for Mathematical Learning, called “Computational Construction as a Means to Coordinate Representations of Infinity“. They describe a design experiment aimed at helping students to explore and develop concepts of infinite processes and objects.
