Time-of-flight elastic recoil detection (ToF-ERD) analysis software has been developed. The software combines a Python-language graphical front-end with a C code computing back-end in a user-friendly way. The software uses a list of coincident time-offlight-energy (ToF-E) events as an input. The ToF calibration can be determined with a simple graphical procedure. The graphical interface allows the user to select different elements and isotopes from a ToF-E histogram and to convert the selections to individual elemental energy and depth profiles. The resulting sample composition can be presented as relative or absolute concentrations by integrating the depth profiles over user-defined ranges. Beam induced composition changes can be studied by displaying the eventbased data in fractions relative to the substrate reference data. Optional angular input data allows for kinematic correction of the depth profiles. This open source software is distributed under the GPL license for Linux, Mac, and Windows environments.

Research has noticed that imparting TDD-like testing to an early computing curriculum is challenging because it increases technical and cognitive load for the students. This paper addresses the challenge with a software-based solution constructed to facilitate the process of writing tests. The solution allows using a compact while efficient syntax for formulating tests, writing tests into JavaDoc comments, thus close to the source code that implements intended functionalities, and automates the generation of actual test code. The constructed solution -the ComTest tool -has now been used in four introductory level programming course offerings. The paper presents the tool and concludes with initial lessons learned.

Relation Analysis is a method to find logical couplings in a software by examining a version control log to see which files change together regularly. However, the process can be twisted into finding, for example, illogical couplings between modules, modules with too much influence or burden with responsibility. In this paper we explain how the Relation Analysis was applied to a course information system written in Java to find out hidden connections between the modules inside the software.

One can easily compare the current style of teaching and lecturing to the so called waterfall model of software development. We first design the course, then execute it, and in the end we make tests to see, if everything went well. As with waterfall model, the assessment comes too late, if anything fails.Therefore, we need a lecturing model which entwines assessment into course execution. Test-driven development (TDD) is a model of software development in which the computer program is designed by writing first small tests that assure the meeting of the requirements. In test-driven lecturing, students first take tests to show how well they master the topics to be discussed. In this way both the students and lecturers are assured that everything is going fine, and if not, the problems are found early, so one can react to them.
