This study analyzed instructional achievement and intrinsic motivation among 21st century secondary students utilizing a video lecture incorporating both student reaction cutaway images and immediate content interaction within the lecture. Respondents (n = 155) were from multiple classes and grade levels at a suburban Texas high school. Four…

In this study, relations between learning activities of teachers and changes in their beliefs were examined. Thirty-four teachers in Dutch secondary education were asked to complete a questionnaire regarding their beliefs about teaching and learning on two occasions. They were also asked to report on learning activities that they undertook.…

Attempts to answer two research questions: (1) Does the use of a digital camera in laboratory activities increase student learning?; and (2) Does the use of digital cameras motivate students to take a greater interest in laboratory work? Results indicate that the digital camera did increase student learning of process skills in two biology…

Performed a variance analysis of the relation between the amount of time students spend experiencing hands-on science and science achievement. Reports that students who engaged in hands-on activities frequently scored significantly higher on a standardized test of science achievement than students who did not. (Author/JRH)

Presented is a review of three methods for evaluating the effects of laboratory work in high school science instruction. The report focuses specifically on evaluating student performance, what aspects are to be evaluated, and how to evaluate. A table is given of some of the limitations and benefits of each of the assessment procedures. The authors…

Described is a procedure for assessment of student performance in laboratory work (practical work) in Advanced Level Biology in England. Some historical background is included. (PB)

Compared the performance of teachers and students on the Field Experiences Achievement Test with results obtained from seventh-grade students who took the FEAT during its development and validation. Results indicate that tests developed for student use may also be used in inservice teacher education programs. (JN)

Some researchers have argued that it is important to match teaching styles with students' learning styles, although a relatively small amount of research has been done on learning styles in science. This study focused on the differences between male and female secondary school chemistry students in an effort to determine the relationship of gender…

Describes research that documents the falsification of laboratory results by chemistry and physics students. Discusses some factors that encourage students to fabricate results and why some students do not feel the need to falsify data. Contains 16 references. (DDR)

Demonstration of chemical reactions is a tool used in the teaching of inorganic descriptive chemistry to enable students to understand the fundamental concepts of chemistry through the use of concrete examples. For maximum benefit, students need to learn through discovery to observe, interpret, hypothesize, and draw conclusions; however, chemical…

Investigated the efficacy of an instructional program designed to induce students to construct a mental scheme in which experimental design and natural experiments are understood as facets of the same problems and which incorporates a general solution procedure applicable to both. Results show a highly significant posttest achievement by the…

This report presents some of the results of two national surveys which assessed the performance of 13-year-old students in science. It includes an outline of the assessment framework; some of the questions which were written to match it; a description of how well, and how differently, students responded to the questions; and suggests how the…

The development of scientific explorations in schools and a framework for their assessment within the context of Britain's Graded Assessment in Science Project (GASP) scheme is described. The criteria for assessing the planning, implementing, concluding, and evaluating of explorations are provided. (KR)
