Language and argument are epistemic tools that learners can use to help them generate and validate knowledge for themselves, as emphasized in NGSS and previous NRC reports. Not all learning environments elicit or support the use of these epistemic tools equally, thus affecting how students grow in competence in relation to their use. The present…

Persistence is a major issue facing students, particularly those who are both female and from underrepresented ethnic minorities (URM). A closer look at the variables affecting their commitment and capacity for continuing the pursuit of their goal allows us to better design support systems that bolster persistence. This study tests a structural…

Science writing, such as lab reports, allows students to form a meaningful understanding of scientific concepts. However, students often view scientific writing as unimportant and utilize surface level approaches when completing writing assignments. The current study implemented three experimental interventions (directly-communicated,…

This study examines whether students enrolled in a general chemistry I laboratory course developed the ability to participate in scientific argumentation over the course of a semester. The laboratory activities that the students participated in during the course were designed using the Argument-Driven Inquiry (ADI) an instructional model. This…

In 2005 India introduced a new National Curriculum Framework aimed at providing a more constructivist approach to learning for all subjects. Previous research on the impact of curriculum reform in other countries (e.g., United States) concluded that for reform to be successful teachers' orientations toward teaching and learning must be considered…

Those who study secondary science teachers are often concerned with preservice or in-service teacher development. Science teacher educators have acknowledged that this focus is limited, as the induction years of beginning teachers are an important component of teacher development. This mixed methods study focuses on the induction years of…

The purpose of this study was to investigate the possible responses to anomalous data obtained from experiments that are repeatable by carrying out additional or alternative experiments in the laboratory. Based on an analysis of responses from scientists to anomalous data taken from identification experiments on the Vinland Map, it was assumed…

The purpose of this study was to investigate (a) what effect the use of interactive computer-based simulations (ICBSs), the use of laboratory inquiry-based experiments (LIBEs), and the use of combinations of an ICBS and a LIBE, in a conceptually oriented physics course, have on science teachers' beliefs about and attitudes toward the use of these…

This article investigates three teachers' conceptions and use of inquiry-based instructional strategies throughout a professional development program. The professional development program consisted of a 2-week summer inquiry institute and research experience in university scientists' laboratories, as well as three academic year workshops. Insights…

The case-based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual…

This was an experiment to test the extended discretion laboratory approach versus a guided-inquiry approach for teaching biology in a university setting. Among three criterion variables (examination, reports, and quizzes), only the laboratory report scores showed differences between groups and group-by-instructor interaction. (Author/YP)

Determined was the effect of autotutorial instruction in the laboratory portion of a general biology course designed for nonbiology majors. Results indicate positive effects in enrollment, increased retention, and improved student achievement. (CS)

A study of 61 high school biology students found that Interactive Video Disk (IVD) simulation was as effective as actual frog dissection in promoting student learning of frog anatomy and dissection procedures. When used as a preparation for dissection, IVD simulation helped students perform better dissections and learn more from doing dissections.…

Compares two grade 12 science classes, one receiving instruction using the Laboratory-Investigative Approach, and the other using the Lecture-Laboratory Approach, in terms of certain cognitive factors and associated attitudes. (GA)
