The study investigated the influence of a connected learning approach for explicit nature of science (NOS) instruction and explicit argumentation instruction, in comparison with a non-connected approach, on students' NOS conceptions and argumentation skills. Participants comprised 42 students enrolled in two sections of grade 10 that were randomly…

Recent instructional reforms in science education aim to change the way students engage in learning in the discipline, as they describe that students are to engage with disciplinary core ideas, crosscutting concepts, and the practices of science to make sense of phenomena (NRC, 2012). For such sensemaking to become a reality, there is a need to…

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…

In order to deepen students' understanding of natural phenomenon and how scientific knowledge is constructed, it is critical that science teachers learn how to engage students in productive scientific argumentation. Simulations for teachers are one possible solution to providing practice-based spaces where novices can approximate the work of…

Understanding how geologists conduct fieldwork through analysis of problem solving has significant potential impact on field instruction methods within geology and other science fields. Recent work has highlighted many aspects of fieldwork, but the problem solving behaviors displayed by geologists during fieldwork and the associated cognitive…

Examines the feasibility of intensive instruction (II) in either the observation of details or hypothesis generation, utilizing a discrepant event filmloop, as a model for improving the open exploration skills of ninth graders. (Author/GA)

Determined whether significant differences exist in cognitive achievement and in the level of acquisition of practical skills among ninth-grade students (N=1025) in cooperative, competitive, and individualistic learning conditions in science laboratories. Results are discussed in terms of their implications for more productive science laboratory…

Studies elementary school childrens' abilities in (1) measuring and constructing angles, and (2) interpreting and constructing linear graphs as a result of instructional formats. Partitioned into instructional treatments of (1) science, (2) science-mathematics, (3) mathematics, and (4) control were 161 fourth- and fifth-grade children. Mathematics…

Investigated different patterns and amounts of instruction on planning experiments with sixth- and eighth-grade students. A model for generating process skill lessons was used to produce all lessons. Three treatments were generated and tested, showing student gains in using process skills of identifying variables and stating hypotheses. (Author/JM)

Determined effectiveness of inquiry approach to science and language teaching to further develop classification and oral communication skills of bilingual Mexican American third grade students (N=64). Results indicate that participation in science inquiry lessons facilitated development of both classification and oral communication skills. (JN)

This study investigated the effectiveness of computer simulations for enhancing the problem solving skills of high school students. Summaries of three related studies are presented. Results indicate that the computerized simulations enabled students to master the objectives of a biology course as effectively as traditional methods. (ML)

Examines (1) how students evaluate information obtained in the science laboratory; (2) the effects of use of microcomputer-based laboratory; and, (3) the effects of explicit instruction on critical evaluation skills. Discusses results in terms of students' propensity to accept incorrect graphs and in terms of the effect of the enhanced instruction…

Reports on a study that investigated the effects of various instructional practices on programming proficiency focusing on characteristics of Pascal classes. States that instructional practices involve extensive on-line access, explicit instruction, and extensive feedback. (ML)
